There are several different types of intraocular lenses (IOLs) that can be used to replace the natural lens during cataract surgery. The most common type is monofocal IOLs, which only focus at one distance and may require reading glasses. Multifocal IOLs allow vision at multiple distances without glasses by dividing the visual field into sections for different focal lengths. Toric IOLs are designed for patients with astigmatism to reduce blurry vision from an irregularly shaped cornea. The document discusses the benefits and suitability of these different IOL options.

How currently achieve an EDoF lens
This document discusses parameters for achieving an extended depth of field (EDoF) intraocular lens. It notes that chromatic aberration (LCA), spherical aberration (SA), refractive index (RI), Abbe number, and high order aberrations (HOA) can influence EDoF, and that LCA, SA, and HOA can potentially be addressed through diffractive optics, aspheric profiles, and low add designs. Specific EDoF lenses discussed include the Zeiss At Lara, Tecnis Symfony, Mini Well, Oculentis Comfort, and IC-8, highlighting their optical performance and ability to extend depth of field while maintaining good visual quality.

RECENT ADVANCES IN INTRAOCULAR LENS
1) Intraocular lenses (IOLs) are artificial lenses implanted during cataract surgery to replace the clouded natural lens and correct vision. 2) IOLs have evolved over generations from rigid PMMA lenses to modern foldable designs made of silicone, acrylic, or hydrogel materials. 3) IOLs can be mono-focal, providing a single vision correction, or multi-focal, attempting to provide both near and distance vision without glasses. Accommodating IOL designs also aim to restore the eye's ability to focus at different distances.
Rose K lens.pptx
The ROSE K family of lenses were invented by Paul Rose to closely mimic the cone-like shape of the cornea for keratoconus. The lenses use complex geometry that can be customized for each eye. They provide excellent corneal health and high success rates of over 80%. Design features include aspheric optics, aberration control, and flexible edge lifts. Standard lenses do not ideally fit keratoconus, but ROSE K lenses contour to the cone shape with little tear pooling at the base. Types include ROSE K2 for irregular corneas, post-graft, and nipple cones. Fitting involves selecting the base curve, optimizing the peripheral fit, diameter, location, movement, and
Toric iol
1) Toric IOLs are used to correct corneal astigmatism during cataract surgery. They have a cylindrical optic to neutralize corneal astigmatism.
2) The material and design of toric IOLs affect their postoperative rotational stability, with acrylic IOLs showing the highest stability. Larger diameter and loop haptic designs also increase stability.
3) Proper patient selection, preoperative measurements, surgical technique, and IOL alignment are important for achieving optimal visual outcomes with toric IOL implantation. Accurate axis alignment is critical to achieve the intended astigmatic correction.
Newer IOLs
This document discusses the evolution of intraocular lenses (IOLs) from early generations implanted in the 1950s to newer IOL designs. It covers generations I-VI of IOLs and their complications. Newer IOL designs discussed in more detail include aspheric, multifocal, accommodative, toric, phakic and aniridia IOLs. The benefits and limitations of different IOL materials and designs are presented.
Multifocal iols
Multifocal IOLs provide both near and distance vision without glasses by utilizing concentric zones of different optical powers (refractive MFIOLs) or diffractive properties to split light between two focal points. While eliminating need for glasses, they can cause visual side effects like glare and reduced contrast sensitivity. Careful patient selection and counseling, accurate biometry and surgical technique are important for successful multifocal IOL implantation outcomes.

Toric iol
This document discusses toric intraocular lenses (IOLs) for correcting astigmatism during cataract surgery. It provides details on the evolution of toric IOL designs from early PMMA lenses that often rotated, to current acrylic models with improved stability. Precise keratometry measurements and accounting for surgically induced astigmatism are important for toric IOL power calculations. The document outlines the toric IOL implantation procedure and factors affecting postoperative rotation. Toric IOLs can provide high levels of spectacle independence when used appropriately in patients with regular corneal astigmatism over 1.5 D.
IOL power calculation formulae
The document discusses various formulas used for calculating intraocular lens (IOL) power, including SRK, SRK2, Holladay, Haigis, and Holladay 2. It explains the factors these formulas account for such as axial length, corneal power, anterior chamber depth, and how they have evolved over generations to improve accuracy. Special considerations for calculating IOL power in cases involving prior refractive surgery, silicone oil filling, posterior staphyloma, and using optical biometry devices are also summarized.
Update in intraocular lenses
This document summarizes an expert lecture on updates in intraocular lenses (IOLs). It discusses the historical evolution of IOLs from 1949 to present day, with over 298 available IOL options now catalogued online. The main characteristics of IOLs that determine their optical features are reviewed, including refractive power, asphericity, toricity and multifocality. Platform designs and their impact on biocompatibility and postoperative outcomes are also evaluated. Specific IOL types like toric, refractive multifocal, and diffractive bifocal and trifocal lenses are then analyzed in depth for their designs and performance characteristics. Head-to-head comparisons of popular trifocal IOL models are made based on visual ac
Specular microscopy
Specular microscopy is used to examine the corneal endothelium and analyze pathological changes. There are contact and non-contact types, with contact providing higher resolution but potential discomfort. The procedure involves placing the patient comfortably and using fixation to keep the eye still while obtaining images. Images are then analyzed to study normal endothelium morphology, diagnose corneal endothelial diseases, and monitor conditions like aging, diabetes, surgery, trauma, and compare surgical techniques. Specular microscopy can detect disorders like Fuchs' endothelial dystrophy and help with decisions like eye banking and surgery.
IOL Selection- What to Ask and What to Tell Patients
This document discusses factors to consider when selecting an intraocular lens (IOL) for cataract surgery. It notes that the patient's visual goals, the surgeon's expertise, and improvements in IOL technology all converge to determine the best IOL choice. Key factors include visual quality, patient expectations and needs, IOL design, and the surgeon's experience. Age-related eye changes and aberrations must also be addressed. Newer "multifocal light" IOLs aim to provide good distance and near vision with fewer side effects compared to traditional multifocal IOLs. The continual goal is high quality vision correction taking into account higher order aberrations like spherical aberration.
ad - IOL power calculation presentation.pptx
- IOL power calculations require considering several factors including axial length, corneal curvature, lens constants, and intended postoperative lens position.
- Different IOL power calculation formulas are better suited for different eye characteristics like normal versus long axial lengths.
- Accurate biometry measurements from devices like the IOL Master and precise consideration of effective lens position are important for accurate IOL power calculations.
- Newer fourth generation formulas like Holladay 2 and Haigis that incorporate additional parameters generally provide the highest accuracy over a wide range of axial lengths.
Diplopia charting
Diplopia charting involves recording the separation of double images seen by a patient in nine positions of gaze. The examiner uses a red glass over one eye while holding a light source in different positions. The patient reports if they see one image, two separate images, or a tilted image. The separation is greatest in the direction of an underacting or paralyzed eye muscle. When recording the results, the patient's right and left sides are noted along with the distance of any separation between images and any tilting. The diplopia chart should be interpreted along with a clinical exam and Hess chart.
Achieving accurate iol power calculations
1. Accurate IOL power calculations require precise measurements of axial length and corneal power using modern devices like optical biometers. Errors in these measurements can lead to incorrect IOL powers.
2. Newer theoretical formulas like Holladay II and Haigis are generally more accurate than older formulas or regression formulas. They take into account additional parameters like anterior chamber depth.
3. Special considerations are needed for calculating IOL power in children, eyes with previous refractive surgery or conditions like high myopia which can affect biometry measurements. Repeat measurements may be needed if initial values are outside normal ranges.

Glass prescription in children
This document provides guidelines for prescribing glasses in children. It discusses that the pediatric eye is different from the adult eye in terms of axial length, corneal curvature, and lens power. The goals of prescribing glasses in children are to provide a focused retinal image and achieve optimal balance between accommodation and convergence. It is more difficult to prescribe glasses for children due to lack of subjective response and poor attention. American guidelines provide recommendations on refractive errors that warrant correction at different ages. Factors like emmetropization, amblyopia risk, and presence of strabismus are considered. Frame selection depends on the child's condition and age, aiming for correct fit, comfort, safety, and not hindering nasal development.
Iol power calculation in pediatric patients
- Many factors affect intraocular lens (IOL) power calculation in pediatric patients including age at surgery, laterality, amblyopia, axial length, keratometry, and expected myopic shift due to ongoing eye growth.
- Normal eye development involves rapid growth of the axial length and changes in lens power in the first years of life.
- Target postoperative refraction must account for this myopic shift and generally involves undercorrecting more in younger patients.
- Accurate biometry using immersion ultrasound or optical techniques is important to minimize errors from corneal compression.
- Formulas, IOL type and position can further influence outcomes.
Assessment of corneal endothelium
This document discusses the corneal endothelium and techniques for assessing its health and function. The corneal endothelium is a single layer of hexagonal cells that maintains corneal clarity by pumping fluid out of the stroma. Assessment techniques described include specular microscopy, which examines cell density, morphology, and patterns at high magnification; confocal microscopy and anterior segment OCT for in vivo imaging; and ultrasound pachymetry to measure corneal thickness as an indicator of endothelial function. Common endothelial diseases like Fuchs' dystrophy and conditions affecting assessment are also reviewed.

Pigment epithelial detachment (PED)
Pigment epithelial detachment (PED) occurs when the retinal pigment epithelium separates from the underlying Bruch's membrane, usually due to fluid accumulation. There are several types of PED including drusenoid, serous, and vascularized PEDs. PEDs can be caused by conditions like age-related macular degeneration and central serous choroidopathy. Optical coherence tomography is used to characterize the type and contents of the PED. Treatment depends on the specific cause and characteristics of the PED.
Toric iol 2
Toric IOLs are intraocular lenses that correct both astigmatism and nearsightedness or farsightedness. They have different optical powers in different meridians of the lens and alignment markings. Toric IOLs can correct between 1-8 diopters of astigmatism, though small rotations may not affect the correction and rotations of 30 degrees or more will eliminate the effect. Limbal relaxing incisions are an alternative that make small incisions in the cornea to reduce astigmatism but only correct 1-3 diopters and the results may change over time. When implanting a toric IOL, the surgeon aligns markings on the IOL with markings made on
Keratometry & autorefraction
Keratometry measures the curvature of the cornea using the reflection of light off the corneal surface. There are two main types - manual keratometers using movable mires or prisms to assess curvature, and automated keratometers using photosensors. Keratometry is used to detect astigmatism, monitor corneal conditions, and assist in contact lens and refractive surgery. It provides important information but has limitations as it only measures the central cornea and assumes a symmetrical shape.

Different Types of Intraocular Lenses in Cataract Surgery.pptx
Intraocular lens or IOL is a premium, tiny and artificial lens for the eye. It is used to replace the natural lens of the eye to remove the cataract. Know what are the different types of IOLs used in the Cataract Surgery.
Mutifocal iols
This document discusses different types of multifocal intraocular lenses (IOLs) used in cataract surgery. There are three main types: refractive, diffractive, and a combination. Refractive IOLs use concentric rings of different optical powers while diffractive IOLs use diffraction optics to create two focal points. Combination IOLs can provide the advantages of both refractive and diffractive technologies. The document also covers specific multifocal IOL models and considerations for patient selection.
Spectacles
This document discusses various types of lenses and coatings used in eyeglasses. It describes unifocal lenses that provide single vision correction and multifocal lenses like bifocals and trifocals that correct for both distance and near vision. Progressive lenses provide a seamless transition between vision corrections. Hi-index and lightweight lenses reduce thickness. Photochromic lenses darken in sunlight and clear in low light. Polarized and tinted lenses reduce glare. Polycarbonate lenses are impact resistant. Anti-reflective coatings improve vision clarity and comfort.
Cataract And Presbyopia
This document discusses cataracts and presbyopia, as well as treatment options performed by Dr. Helga Fuenfhausen Pizio. A cataract is a clouding of the eye's lens that causes vision problems and is common in older adults. Symptoms include blurry or faded vision. Surgery is the only treatment and involves removing the clouded lens and replacing it with an artificial lens. For presbyopia, which causes near vision issues, multifocal lenses can provide both near and distance vision after cataract surgery without glasses. Dr. Pizio performs cataract surgery using small incisions and ultrasound and was the first in Nevada to implant a new multifocal lens.
Accommodative and multifocal intraocular lenses
This document discusses accommodative and multifocal intraocular lenses (IOLs) that are surgically implanted to replace the eye's natural lens and help restore vision and the ability to focus at different distances. It provides information on how the eye works, common refractive errors, the IOL procedure, types of IOLs including multifocal and accommodative IOLs, risks and considerations, and whether refractive surgery is right for a given patient.
Intraocular lens
The document summarizes the history and generations of intraocular lenses (IOLs). It discusses the first IOL implanted by Sir Harold Ridley, made of polymethyl methacrylate (PMMA). Later generations included foldable materials, multifocal IOLs, and accommodating IOLs. Premium IOLs now offer features like toric designs to correct astigmatism and aspheric optics for better vision quality. While multifocal IOLs provide simultaneous distance and near vision without glasses, they can cause visual side effects like halos and reduced contrast sensitivity. Accommodating IOLs aim to restore a degree of natural accommodation but may not provide fully unaided near vision for small print.
Multifocal contact lens
Multifocal contact lenses can correct both near and distance vision and are an alternative to bifocal glasses for people with active lifestyles. There are several types of multifocal contact lens designs, including soft, gas permeable, and hybrid lenses. The most common design is a diffractive lens with concentric circles of different optical powers. Multifocal contact lenses provide clear vision at multiple distances but may cause glare or hazy vision during adjustment. They also have advantages like less need for extra eyewear but disadvantages such as greater difficulty adapting to them.
Marietta Eye Clinic's Eyewear Center
This document discusses various lens options available at an Eyewear Center. It describes designer frames that come with a one-year breakage warranty. It also discusses the advantages of progressive lenses that provide multifocal vision. Anti-reflective lenses are described as enhancing prescription lenses by allowing 99% light transmission for better sharpness and clarity. Transitions lenses are highlighted as conveniently adjusting tint levels based on outdoor light conditions to reduce glare and eye strain.
Presbyopia
Presbyopia is the loss of accommodation that occurs with aging. It results in a decreased ability to focus on near objects and is caused by lenticular and extralenticular changes within the eye. Symptoms typically begin around age 40 and accommodation is completely lost by ages 50-60, affecting 100% of the population. Treatment options include reading glasses, bifocal and multifocal contact lenses, refractive surgery such as LASIK, and intraocular lens implants. Newer treatments being researched include corneal inlays and injectable accommodating intraocular lenses.
Comparing Extended-Depth-Of-Focus and Multifocal IOLs
Based in Rockville, Maryland, Dr. Anthony Roberts provides client-centered ophthalmology care for a broad range of eyesight issues such as glaucoma, corneal disease, dry eyes, and diabetic retinopathy. Offering advanced Lasik procedures, Dr. Anthony Roberts provides extended-depth-of-focus (EDOF) intraocular lens (IOL) options to patients with complex vision challenges.
IOLs are typically implanted as part of refractive lens exchange or following cataract extraction, within the surgical treatment of presbyopia. Traditional multifocal IOLs employ diffractive optic lenses and separate light between near, intermediate, and long distances. This means that the user is only able to focus on a single distance at a time, with blur, halo, and glare sometimes occurring due to the multiple focal points.
By contrast, EDOF-IOLs provide a single elongated focal point that seamlessly improves depth of focus and range of vision. This emerging technology is ideal for patients who do not want their functional vision compromised as they shift focus across distances.

This document discusses various intraocular lens (IOL) options for treating presbyopia during cataract surgery. It describes multifocal IOLs that provide simultaneous focus at multiple distances using diffractive or refractive optics, as well as accommodating IOLs that aim to mimic the eye's natural lens. Popular multifocal IOL models include the ReZoom, AcrySof ReSTOR, and Tecnis, while the Crystalens is an example of an accommodating IOL. The document also addresses factors to consider when selecting an IOL and managing patient expectations.
Modern cataract surgery
Cataract is the opacification of the natural lens in the eye that can disturb vision. Modern cataract surgery aims to remove the cataract through small incisions using various techniques like phacoemulsification while implanting an intraocular lens (IOL) to replace the natural lens. IOLs are made of materials like acrylic and silicone and can be monofocal, multifocal, or toric to correct vision and astigmatism with the goal of minimal surgery and fastest recovery of quality vision.

Contact lenses air optix
There are two main types of contact lenses: hard and soft. Hard contact lenses are made of plastic, silicone, or fluoropolymers and hold their shape firmly over the eye. Soft contact lenses are made of flexible plastic and are more comfortable but require daily removal. An eye doctor can help determine which type is best based on an individual's lifestyle and eye health factors. Proper cleaning and disinfecting of lenses is important to prevent infection.
Types of Camera Lens
Camera lenses come in a variety of types to suit different photographic needs. The major types of digital camera lenses are standard lenses, macro lenses, telephoto lenses, wide angle lenses, specialist lenses, and kit lenses. Standard lenses have a mid-range focal length similar to human vision. Macro lenses are designed for close-up photography while telephoto lenses provide magnification for distant subjects. Wide angle lenses capture a wider field of view and fisheye lenses use strong distortion. Specialist lenses create specific effects while kit lenses are basic lenses bundled with entry-level cameras. The type of lens used depends on the subject and photographic goals.

OCULAR BIOMETRY AND IOL.pptx
Intraocular Lens (IOL) power calculation is a crucial step in cataract surgery and certain refractive surgeries like phakic IOL implantation. The goal is to determine the appropriate power of the IOL to be implanted into the eye, ensuring that the patient achieves their desired postoperative visual outcome. Several formulas and methods are available for IOL power calculation, and the choice of formula depends on various factors, including the patient's eye measurements and the surgeon's preference. Here, we describe the basic principles and some commonly used formulas.
Ocular Biometry:
Ocular biometry is the process of measuring various dimensions of the eye, primarily the axial length, corneal power, and anterior chamber depth. These measurements are essential for accurate IOL power calculation and achieving the desired post-surgical refractive outcome. Here are the key components of ocular biometry:
Axial Length: This measurement determines the overall length of the eye, from the cornea's front surface to the retina's back surface. Axial length is a critical factor in IOL power calculation because it helps determine the eye's focusing power.
Corneal Power: The cornea is the transparent front surface of the eye, and its curvature affects the eye's refractive power. Corneal power is typically measured using techniques like keratometry or corneal topography. It helps account for the eye's astigmatism and assists in selecting the appropriate IOL.
some basic notions on how they are measured is explored here.
Corneal Cross-Linking .pptx
Corneal cross-linking is a treatment for keratoconus that uses riboflavin eye drops and UV light to strengthen the collagen in the cornea. There are two types of cross-linking - epithelium-off which removes the outer corneal layer, and epithelium-on which leaves it intact. Cross-linking adds bonds between collagen fibers to help stabilize the cornea. It is best used early in keratoconus before the cornea becomes severely irregular. Keratoconus causes the cornea to thin and bulge into a cone shape due to weakened collagen from decreased antioxidants. It is diagnosed based on changes in corneal shape and vision problems. Treatment options include glasses, contacts, cross-linking, and

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort. acne vulgaris -Mpharm (2nd semester) Cosmetics and cosmeceuticals

TYPES OF INTRAOCULAR LENSES.pptx
- 1. DIFFERENT TYPES OF CATARACT LENSES AY I E N W I F R U B I H R N . C O A
- 2. CATARACT LENSES ? During cataract surgery, the natural lens of the eye is removed and replaced with an intraocular lens, or an IOL. These cataract lenses are designed to restore and correct vision for those suffering from cataracts. There are many different types of cataract lenses available, and each type of lens provides specific benefits. WHICH OF THEM IS GOOD FOR YOU?
- 3. TYPES OF CATARACT LENSES
- 5. MONOFOCAL IOLS The most common types of cataract lenses are monofocal IOLs. Monofocal lenses only have one focusing distance. • Distance • Intermediate • Near— Depending on your preferences. Most cataract patients choose monofocal IOLs that allow them to focus on things at a distance and use reading glasses when needed.
- 7. MULTIFOCAL IOL For those who want to achieve optimum vision at all distances, multifocal IOLs are the cataract lenses for you. Unlike monofocal IOLs, multifocal lenses allow you to see well at more than one distance. Multifocal lenses are usually only used if they can be implanted into both eyes, and will work best for patients who don’t have any eye diseases.
- 9. ACCOMMODATING IOLS This type of lens works with the implant inside the eye as it moves to help you focus at various distances. Overall, accommodating IOLs are known to provide enhanced distance vision for many cataract patients. However, compared to the other options, it’s not ideal for near vision.
- 11. TORIC IOLS Toric IOLs are designed for those with cataracts who want to reduce astigmatism. Toric IOLs are usually recommended for those with corneal astigmatism, or blurry vision caused by an irregularly shaped cornea. These cataract lenses are available in several powers, and can help correct a range of diopters of astigmatism.
