The document describes the iDESIGN Advanced WaveScan Studio System, a new technology for wavefront-guided LASIK. It captures over 1,200 data points from each eye, more than previous technologies, to create a highly personalized treatment plan. The system is indicated for correcting nearsightedness up to -11 diopters and astigmatism up to -5 diopters. Clinical studies showed 99% of patients had clear, sharp vision without limitations after surgery.
Final clinical outcomes of laser refractive surgerySwetha Velpula
This document summarizes an optometrist conference that reviewed laser refractive surgery procedures. It discussed that LASIK can currently treat up to 11 diopters of myopic astigmatism and 4.5-5 diopters of hyperopic astigmatism. It is important to perform thorough preoperative evaluations including corneal topography and pachymetry. Results from the local eye center showed that 76% achieved 6/6 or better unaided vision after LASIK and PRK procedures. Complications were low, with only 2 eyes requiring enhancement procedures.
Extracapsular cataract surgery involves removing the clouded lens and surrounding capsule from the eye. The most common method is phacoemulsification, which uses ultrasound to break up the lens for removal through a small incision. After removal of the cataract, an intraocular lens implant is typically placed. Surgery is usually quick and has a high success rate in improving vision, but risks include infection, swelling, bleeding or complications that may require further treatment.
The document discusses refractive surgery procedures for correcting vision, including LASIK, PRK, and lens implants. It describes how each procedure works to reshape the cornea and lens to reduce nearsightedness, farsightedness, and astigmatism. The risks are generally low but include infection, glare, and gradual refractive change over decades. The benefits are improved vision, though not necessarily perfect vision. Costs typically range from $1000 to $2500 per eye.
LASIK is a laser eye surgery procedure that can permanently correct vision problems like nearsightedness, farsightedness and astigmatism. It involves using a laser to reshape the cornea to improve vision and eliminate the need for glasses or contacts. To be eligible for LASIK, a person must be at least 18 years old and have stable vision for at least a year. An eye exam will determine if a person's eyes and corneal thickness make them a suitable candidate for the procedure. If eligible, LASIK only takes a few minutes per eye and most people can return to regular activities within a day or two with a high success rate and minimal risks.

Glaucoma is a leading cause of irreversible blindness that damages the optic nerve and results in progressive vision loss. It is often asymptomatic in early stages. Glaucoma is controlled by lowering eye pressure through eye drops, laser treatment, or surgery. Regular monitoring is required long-term to preserve remaining vision as damage cannot be reversed. Risk factors include family history, age, eye injuries, and certain medical conditions. Early detection through eye screening can prevent vision loss from glaucoma.
Retinal detachment occurs when the retina separates from the back of the eye. It is a medical emergency that can cause permanent vision loss if not repaired. The retina is made up of layers and receives images that the brain interprets as vision. Retinal detachment can be rhegmatogenous, tractional, or exudative and risks include nearsightedness, eye surgery or injury. Diagnosis involves eye exams and ultrasound. Treatment may involve laser, cryotherapy, scleral buckle surgery, pneumatic retinopexy or vitrectomy to seal retinal breaks and reattach the retina. Nursing care focuses on medication administration, activity safety, and education on signs of recurrence and postoperative care.

- A cataract is a clouding of the lens in the eye that can cause vision loss. It is often related to aging but may be caused by other factors like smoking.
- Symptoms include decreased vision, glare from lights, and frequent changes to prescriptions. Cataract surgery is usually done to replace the cloudy lens with an artificial lens implant.
- There are different types of intraocular lenses that provide varying levels of vision correction and independence from glasses after surgery. Conventional lenses correct one distance while newer lenses aim to provide multifocal vision.
This document discusses visual disorders and low vision. It defines different levels of visual impairment from moderate to profound based on best corrected visual acuity and visual field diameter. Causes of low vision including various eye diseases are described. Methods of low vision evaluation and different low vision devices like magnifiers, telescopes, electronic devices are explained. Low vision rehabilitation strategies including use of assistive devices and training are also summarized.
Dr. Om Patel presented on myopia (nearsightedness). There are several types and causes of myopia, including axial myopia caused by an elongated eyeball, curvatural myopia from increased corneal or lens curvature, and pathological myopia associated with degenerative changes. Treatment options discussed included optical correction with glasses or contacts, as well as surgical procedures like LASIK, PRK, and phakic intraocular lenses for high myopia. The goal of treatment is to slow progression and provide clear vision.
The document discusses various topics related to contact lenses and corneal treatments including:
1) Edge lift and edge clearance in contact lens design and their effects on tear exchange and lens movement.
2) Corneal topography, its uses in evaluating conditions like keratoconus and fitting contact lenses. Different topography devices are also mentioned.
3) Corneal cross-linking for progressive corneal conditions like keratoconus to strengthen the cornea using riboflavin and UV light. Various techniques and the procedure are outlined.
Retinal detachment is a serious condition where the retina peels away from its underlying supportive tissue layer. It can cause permanent vision loss if not repaired soon. The summary examines the risk factors, types, signs and symptoms, diagnosis, and treatment options for retinal detachment. Surgical methods like scleral buckling, cryopexy, laser photocoagulation, pneumatic retinopexy and vitrectomy aim to reattach the retina. Prompt treatment usually leads to vision improvement, though the prognosis depends on factors like macula involvement and presence of proliferative vitreoretinopathy. Post-operative care and home management are important to monitor for complications and aid recovery.
The document provides an introduction to refractive surgery. It discusses different vision conditions like myopia, hyperopia and presbyopia. It explains how these conditions can be corrected through glasses, contact lenses or refractive surgery options like LASIK and PRK. It addresses common myths about refractive surgery, discussing the safety, effectiveness and long-term outcomes of these procedures.
This document outlines pre- and post-surgery protocols for refractive surgery cases. It discusses evaluating patients for stability and medical history, performing exams of visual acuity, keratometry, eye pressure and retina. LASIK criteria include determining stability after contact lens removal. Post-LASIK follow up includes vision checks and flap/inflammation monitoring for 1 year. Medication protocols involve pre- and post-op antibiotics and steroids. Risks include dryness, glare and halos.
This document discusses advanced surface ablation procedures like PRK and LASEK for correcting refractive errors like myopia, hyperopia, and astigmatism. It describes how the eye works, different types of refractive errors, and the PRK and LASEK procedures. For PRK, the epithelium is removed and the laser reshapes the cornea. For LASEK, the epithelium is displaced using alcohol before reshaping the cornea and replacing the epithelium. Both procedures involve a bandage contact lens and have risks like blurry vision, halos, or need for retreatment. Patients should discuss their options and expectations with their ophthalmologist to determine if refractive surgery is right for them.

This document discusses preoperative evaluation and measurements that should be performed for patients undergoing cataract surgery. It describes testing visual acuity under different lighting conditions, performing refraction, and using glare testing and contrast sensitivity testing to evaluate visual function. External examination of the eyes and adnexa and assessment of motility, pupils, conjunctiva, cornea, anterior chamber, and iris are also recommended to inform surgical planning and ensure patient safety.
VISUAL AIDS FOR CHILDREN IN LOW VISION AND CONTACT LENSITM UNIVERSITY
This document discusses visual aids for children with low vision. It begins by defining low vision according to WHO classifications. Common causes of low vision in children are then outlined, including albinism, retinopathy, and macular degeneration. Both optical and non-optical low vision aids are described. Optical aids discussed include magnifying spectacles, hand magnifiers, stand magnifiers, telescopes, tinted lenses, and filters. Non-optical aids include reading lamps, writing guides, and bold line paper. The principles of low vision aids and factors to consider when prescribing them are also summarized. Contact lenses that can help children with low vision conditions such as aphakia and corneal problems are briefly mentioned.
The document discusses various refractive surgeries including PRK, LASIK, and LASEK. It covers prerequisites for surgery such as patient counseling, age requirements, and testing that should be done. The different types of refractive surgeries are categorized as corneal-based, lenticular-based, or combined. Specific procedures like PRK, LASIK, and LASEK are described in detail, outlining their advantages and disadvantages. Potential complications are also reviewed. In summary, the document provides an overview of different refractive surgery options and important considerations for patient evaluation and treatment.
Refractive eye surgeries have become enormously popular worldwide.
Although numerous types of surgical and laser refractive procedures are available today, a procedure known as laser in situ keratomileusis (LASIK) to correct nearsightedness is currently the most common type.
The document discusses refractive surgeries and provides details on LASIK (Laser-Assisted In Situ Keratomileusis) specifically. It summarizes that LASIK combines lamellar corneal surgery using a microkeratome to create a corneal flap with excimer laser ablation of corneal stroma beneath the flap. The procedure involves creating a corneal flap using a microkeratome, ablating the stroma with an excimer laser according to a calculated profile, and repositioning the flap. Complications are minimized as the flap protects underlying tissues from the laser.

Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
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.

The measurement and treatment of refractive errors has been profoundly beneficial to people. Over the last several hundred years, correcting errors of refraction with spectacles, and later contact lenses, has provided countless millions of people with good vision. With the advent of wavefront technology, we can now better assess the visual function of the eye. No longer restricted to measuring sphere and cylinder, wavefront aberrometers can now quantify other types of aberrations that can impair vision, such as coma and spherical aberration. Using these devices, we are gaining a much better appreciation of the optical characteristics of the eye. In addition to this robust diagnostic capability, wavefront technology is now being used to treat ocular aberrations in the form of wavefront-guided laser-assisted in situ keratomileusis (LASIK).
WFG LASIK, is a variation of refractive surgery where, in the preoperative stages, a highly precise 3-D map of the eye is generated, detailing higher and lower order aberrations (HOAs/LOAs) in the eye. The wavefront capture provides an accurate assessment of the eye and allows the surgeon to tailor the excimer laser, and, rather than applying a sphero-cylindrical correction to the cornea, the laser is instructed to ablate a sophisticated spatially variant pattern based on measurements from an aberrometer.

The iDESIGN System is smart technology that creates an intricate, personalized map of your eye
The technology behind the iDESIGN System was originally developed for high-powered telescopes to view distant objects in space.
Working like a computer “brain,” the iDESIGN System takes 5 different types of measurements of the eye to create a detailed picture of the eye’s imperfections.
These measurements give your doctor a representation of the patient’s vision, based on the behavior of light waves. This device compares the behavior of light passing through the eye to the behavior of light as it would pass through an ideal eye without nearsightedness or astigmatism
This personalized, detailed picture is unique to each patient – just like a fingerprint, no two are alike
Your doctor develops a 100% personalized treatment plan based on these comprehensive measurements.
The iDESIGN system can capture the shape of the cornea; its curvature/power; the ocular wavefront; a patient's refraction (how light passes through the eye); and pupil diameter under different lighting conditions − all in one scan of the eye.
Wavefront refraction measures the refractive error of the patient - more reproducible (repeatable) than the manifest refraction – where the patient gives input, subjective
Wavefront aberrometry measures refractive aberrations of the eye, detects the higher order aberrations in the eye. Complex aberrations include distortions such as coma, trefoil, and spherical aberration, as well as numerous others that cannot be adequately corrected through spectacle lenses.
Keratometry measures the curvature of the anterior surface of the cornea.
Corneal topography – map gives information about the shape of the cornea.
Pupillometry measures pupil diameter under controlled scotopic and photopic lighting conditions.
By providing more high-quality measurements, the iDESIGN system improves iris registration – maximizing the chances for successful iris registration. The iDESIGN system takes an image of the patient’s iris and notes up to 24 identifying marks. This image is transferred with the treatment plan to the excimer laser. The patient’ s eye rotates when moving from sitting to lying down so the excimer laser rotates the treatment to ensure it is positioned correctly.
Your LASIK procedure just got smarter, giving you the freedom to live hassle-free from contacts or glasses
The iDESIGN System captures more data than ever before, creating a detailed picture of your eye’s unique imperfections and accurately plans a treatment that’s 100% personalized
With its outstanding accuracy, iDESIGN System can help correct a broader range of astigmatism (up to -5D) in people with nearsightedness.
