This document discusses different types of intraocular lenses (IOLs) used to correct presbyopia. It begins by explaining that monofocal IOLs only correct far vision and do not provide near vision correction without glasses. It then describes multifocal IOLs, including bifocal and trifocal lenses, which aim to provide both near and far vision corrections simultaneously. The document discusses key principles and technologies used in multifocal IOLs, specifically refractive lenses with multiple zones, diffractive lenses using interference patterns, and apodized diffractive lenses. It provides details on specific IOL models and compares technologies between traditional bifocal, trifocal, and newer trifocal lenses.
This journal club discussed a study that evaluated the visual outcomes of binocular implantation of a new extended depth of focus intraocular lens called the Supraphob Infocus IOL. The study aimed to assess the safety and efficacy of this lower cost IOL in patients undergoing cataract surgery compared to the FDA approved TECNIS Symfony IOL. The study found that the Supraphob Infocus IOL provided good visual acuity, contrast sensitivity, and stereoacuity outcomes comparable to the TECNIS Symfony IOL. It also induced less ocular aberrations. Based on its safety, efficacy and lower cost, the study concluded that the Supraphob Infocus IOL can
The document discusses aspheric intraocular lenses (IOLs) and how they can improve vision quality compared to conventional spherical IOLs. It provides evidence that aspheric IOLs reduce spherical aberration and increase contrast sensitivity and functional vision compared to standard IOLs. The document also notes that factors like biometry measurements, IOL calculation formulas, and surgical technique are important for achieving optimal visual outcomes with aspheric IOLs.
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.

IOL Selection- What to Ask and What to Tell Patientspresmedaustralia
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.
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.
Monovision is a technique for correcting presbyopia by giving the person clear vision both near and far. It works by correcting one eye for distance and the other eye for near vision, inducing anisometropia. The brain learns to use the distance eye for far and the near eye for close up. It is most successful when the non-dominant eye is corrected for near. Multifocal IOLs provide multiple focal points in each eye to give clear vision at different distances, but reduce contrast sensitivity and can cause glare or halos. Factors like dominance, suppression, lifestyle and expectations must be considered for both techniques.

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 challenges and new technologies for accommodating intraocular lenses to treat presbyopia. It summarizes several hinged and dual-optic accommodating IOL designs currently in development or clinical trials, including their mean accommodative amplitudes. However, it notes that fibrosis and capsular contraction often reduce accommodative abilities over time for hinged lenses. Other challenges include determining optimal lens powers and preventing complications. The document explores several experimental technologies as well, but notes many hurdles remain to restoring full accommodation.
Visual acuity and patient satisfaction results with a new trifocal diffractiv...presmedaustralia
The document summarizes a study evaluating visual acuity and patient satisfaction results with a new trifocal diffractive intraocular lens (IOL). 32 patients underwent bilateral implantation of the AT LISA 839MP IOL. At 8-12 weeks post-op, patients had good unaided distance, intermediate, and near vision. A survey found greatly improved unaided vision and high satisfaction, though some reported increased glare and halos. The IOL provided good intermediate vision without compromising other distances. Results demonstrated the IOL's effectiveness in reducing spectacle dependence.
Sir Harold Ridley was the first to successfully implant an intraocular lens in 1949 using polymethylmethacrylate (PMMA). Early intraocular lenses had high complication rates of dislocation and glaucoma. The evolution of intraocular lens design led to foldable lenses made of silicone and acrylic materials that are implanted in the capsular bag for better stability and lower complication rates. Modern multifocal and toric intraocular lenses provide patients with independence from glasses by correcting presbyopia and astigmatism. Precise biometry and surgical technique are important for optimal outcomes with premium intraocular lenses.
Accommodative and multifocal intraocular lensesBijan Farpour
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.
An intraocular lens (IOL) is an artificial lens implanted in the eye during cataract surgery or refractive lens exchange to replace the natural crystalline lens and correct vision. IOLs have evolved over generations from rigid PMMA lenses to modern foldable designs made of silicone, acrylic, or hydrogel materials. IOLs are either placed in the posterior chamber behind the iris or in the anterior chamber in front of the iris. Newer multifocal and accommodating IOL designs aim to provide both distance and near vision. Precise biometry is required to calculate the optimal IOL power to achieve the desired postoperative refraction. Potential complications include dislocation, opacification, deposits, and inflammation.
This document provides information on various types of phakic intraocular lenses (IOLs) that are implanted to correct refractive errors while leaving the natural lens in place. It discusses the history of phakic IOLs and describes anterior chamber angle-supported IOLs, iris-fixated IOLs, and posterior chamber phakic IOLs. The key points covered include the indications, surgical procedures, power calculation methods, potential complications, and advantages/disadvantages of each phakic IOL type.

1) The document describes a study on using secondary intraocular lens (IOL) implantation through the piggyback technique to correct residual refractive errors after cataract surgery.
2) 5 eyes that had primary IOLs implanted in the capsular bag underwent secondary Sulcoflex IOL implantation in the ciliary sulcus.
3) Results found median uncorrected and corrected distance visual acuity improved after secondary IOL implantation. The median spherical equivalent refractive error was within 0.00 diopters of the targeted correction.
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.
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.

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.
The document discusses considerations for selecting premium intraocular lenses (IOLs). It emphasizes listening to patients' desires and managing expectations. Various IOL options are suitable for different patients depending on their visual needs, personality, and ocular health factors. Careful preoperative evaluation, surgical technique, and postoperative management can help optimize outcomes and patient satisfaction.
This study compared visual outcomes after cataract surgery using femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification (CPS) with implantation of an extended depth of focus (EDOF) intraocular lens (IOL). The study found that FLACS produced significantly less IOL decentration and tilt, lower wavefront aberrations, better contrast sensitivity, and fewer visual disturbances reported by patients. Therefore, FLACS may provide improved visual performance compared to CPS when using an EDOF IOL by achieving a more precisely centered IOL position. The study provides evidence that lens positioning is an important factor for optimal visual outcomes with EDOF IOLs.

This document summarizes the one-year outcomes of presbyopia correction using monovision surface ablation (PresbyMAX μ-Monovision PRK) in 44 eyes of 22 myopic and hyperopic patients. Key results include: 1) Myopic patients achieved refractive stability between 1-3 months, with good distance and near vision, while hyperopic patients showed stability at 6 months; 2) Visual and refractive outcomes met or exceeded targets in both groups; 3) Safety was high with no loss of more than one line of vision; 4) Outcomes support PresbyMAX as an effective treatment for presbyopia.
This document discusses various options for treating presbyopia, including corneal inlays. It provides details on three types of corneal inlays - Raindrop, Flexivue Microlens, and Kamra. Raindrop uses a hydrogel implant to change corneal curvature and improve near vision. Flexivue Microlens is a removable hydrogel lens that creates two focal points for bifocal vision. Kamra utilizes a small aperture to increase depth of focus by blocking peripheral light rays. Both Flexivue and Kamra are approved in Europe but still in clinical trials in the US, while Raindrop is also in US trials and approved in Europe.

2) Endovascular interventions had high restenosis and failure rates, while open surgeries resulted in better mid-term patency but higher amputation rates.
3) An aggressive surgical approach along with intensive medical management and follow-up is needed for these high-risk patients due to their underlying disease and risk factors. A multidisciplinary team approach

This document discusses the classification of gastroesophageal reflux disease (GERD) and challenges in classifying patients. It notes that while some patients with typical GERD symptoms respond to treatment, they remain unclassified and may not actually have GERD. A single classification system based on symptoms and endoscopy does not capture all clinical conditions related to GERD. Patients who do not respond to PPIs should be referred to a gastroenterologist. Some GERD patients have significant esophageal motility issues. Those who do not respond to PPIs may require an esophageal biopsy. Some PPI responders actually have eosinophilic esophagitis. Some GERD patients have multiple gastrointestinal comor

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

The skin is the largest organ and its health plays a vital role among the other sense organs. The skin concerns like acne breakout, psoriasis, or anything similar along the lines, finding a qualified and experienced dermatologist becomes paramount.
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

Trifocal intraocular lenses: a comparison of the visual performance and quality of vision
provided by two different lens designs. Gundersen GK, et al.
• Purpose: To compare PanOptix and FineVision trifocal IOL designs, evaluating longer-term refractive
outcomes, visual acuity (VA) at various distances, low contrast VA and quality of vision.
• Methods: 60 patients binocularly implanted (30 patients per group) were evaluated 6 months to 2 years
after surgery.
• Results:
- BCIVA & UIVA were significantly better for the
PanOptix lens at 60 cm (p<0.01).
- The binocular defocus curves differed −1.0 D
(FineVision better), −1.5 and −2.00 D (PanOptix better)

Visual performance after bilateral implantation of 2 new presbyopia-correcting intraocular
lenses: Trifocal versus extended range of vision. Monaco G, et al.
• Purpose: To compare the visual outcomes and quality of vision of PanOptix and Symfony IOLs
with those of a monofocal IOL (AcrySof SN60WF)
• Methods: 20 patients in each arm of the study (60 patients,120 eyes) completed the outcome
assessment at 4 months postoperatively
• Results:
- PanOptix had significantly better near VA
(0.02 ± 0.06 logMAR) than Symfony group
(0.07 ± 0.08 logMAR; p=0.05)
- The defocus curve showed PanOptix IOL
had better intermediate/near performance than
the Symfony lens and both multifocal IOLs
performed better than the monofocal IOL (figure)
