Cataract Surgery Patients - Which Implant Is Right for Me?
Cataract surgery is an advanced outpatient procedure that helps many people to see better each year. We routinely perform cataract surgery through a microscopic incision using just eye drops for anesthesia, as well as IV sedation. The cataract surgery takes a few minutes on average and the complication rate is low for most eye surgeons. A cataract is a clouding of the lens of the eye and it is removed using gentle computer controlled ultrasound called phacoemulsification. Once the defective lens of the eye is removed, the cataract surgeon places an intraocular lens implant or IOL to restore vision.
There is a choice in implants these days and it is important that you discuss your options with your cataract surgeon. Dr. Jeffrey Martin feels that your eye surgeon should be aware and comfortable with the implant choices that are currently available, and advise patients on which implant is right for them based on their individual needs. The standard implant generally corrects nearsightedness and farsightedness and patients that have little to no astigmatism do well with a standard implant, but they will need glasses for near vision. If a patient has astigmatism, which is a cornea that is oblong instead of spherical, there are toric implants that correct astigmatism. This will give a patient with astigmatism the best chance at glasses-free distance vision.
Patients that desire near and far vision without glasses or contact lenses have three FDA approved implant lens options that provide the best chance at greatest range of vision. There is the accommodating lens, Crystalens, which has three subtypes of lenses. The basic idea is that the lens moves in the eye slightly when a patient focuses and gives better far and near vision without glasses and contact lenses. The multifocal lenses Tecnis Multifocal and ReSTOR have a ring pattern to the lens that gives simultaneous near and far vision. With multifocals, part of the light is focused for near and part of the light is focused for distance.
These modern premium implants have revolutionized cataract surgery and make life easier for those patients that need cataract surgery. Dr. Jeffrey Martin is encouraged by the current technology in cataract surgery and excited about the future.
