Patients who receive this type of IOL will still require glasses for intermediate and near vision after surgery If you are experiencing difficulty seeing up close without the use of reading glasses, you may be a candidate for one of the new technologically advanced IOLs that can provide a full range of vision.This means that you could see clearly at distance and near and everything in between, with little or no dependence on bifocals or reading glasses.Intraocular lenses, or IOLs, are implantable lenses that are used to replace the natural lenses of the eyes when they have become damaged.Scientists originally designed IOLs to treat cataracts.I have been doing a lot of research on the success rate of cataract surgery of paitients with high nearsightedness.I am really getting anxious because there seems to be a lot of risk involved.Stanley Chang, MD (Harkness Eye Institute, New York). Chang is chairman of the Harkness Eye Institute at Columbia University and on staff at Columbia University Medical Center and New York-Presbyterian Hospital in New York.His areas of expertise include complex retinal detachment, diabetic retinopathy and macular disorders. Chang developed several revolutionary surgical approaches to treat complicated forms of retinal detachment and he was the first to use perfluoropropane gas in the management of retinal detachment worsened by scar tissue proliferation.
surgeon to implant the light-adjustable artificial lens and the first dual-optic accommodating IOL. Chang has designed a number of popular cataract surgical instruments that bear his name and are used worldwide.As scientists continue to research cataracts and ocular health, we are likely to see even more types of IOLs.Nevertheless, today's lenses offer outstanding results. Most patients are happy with their procedures, and they enjoy significantly improved vision.Cataracts are opacities that form in the eye’s crystalline lens and are caused by a breakdown of tissue and accumulation of proteins that make up the lens.Over time, cataracts cloud the lens and do not allow light to reach the retina, producing blurred vision.
