Intraocular Implants in Cataract Surgery

A cataract is a clouding of the natural crystalline lens of the eye. As people age, the lens of the eye naturally becomes more dense and eventually begins to opacify. This causes symptoms such as glare from oncoming headlights while driving at night, glare from sunlight, and general blurred vision. When the symptoms of cataract become significant enough, Dr. Jeffrey Martin, of North Shore Eye Care, suggests cataract surgery in Long Island at our practice. Dr. Jeff Martin is an Assistant Clinical Professor of Ophthalmology at SUNY Stony Brook, and is an expert in cataract surgery. Dr. Martin feels that cataract surgery should be done through a small incision without stitches in most cases assisted by eye drops for ocular anesthesia and IV sedation. Successful cataract surgery usually takes a few minutes and patients return home the very same day.
When a cataract is removed, we replace the defective lens with an intraocular implant or IOL. Patients may choose a standard implant that is usually covered by insurance and will give a patient good distance vision if they do not have astigmatism. Patients with standard implants will need glasses to clearly see near objects. Many of Dr. Martin's patients choose advanced technology IOLs that are designed to reduce the need for glasses to see far and near objects. Patients that choose a multifocal or accommodating implant are the most likely to eliminate dependency on glasses or contact lenses. These lenses include the Crystalens, ReSTOR, ReZoom, and Tecnis Multifocal. There is also a Toric implant from Alcon that is able to reduce or eliminate astigmatism. The Toric implant is an excellent choice for patients with astigmatism.
