Understanding Cataracts
A cataract is the clouding of the eye’s natural crystalline lens. The lens assists with focusing light rays on to the retina, which translates the image to the brain. After the lens starts to cloud it is impossible to return the lens to its clear state with medications. It is at this time that cataract surgery is necessary. Some people think a cataract is a growth on the outside of the eye but a cataract is actually the gradual clouding occurring with the lens located inside your eye just behind the pupil.
Cataract Surgery
Cataracts are removed using no needle, small incision surgery known as phacoemulsification. After application of anesthetic eyedrops an incision of 1.8 to 2.7 millimeters in length is then created where the cornea, the clear domed structure on the front of the eye, and the white part of the eye, known as the sclera meet. The cataract is broken into many small pieces using an ultrasonic device and simultaneously removed from the eye.
Once all of the cataract material has been removed, a folded intraocular lens is inserted through the original incision. The lens is then maneuvered into the lens capsule and centered. The lens will remain inside your eye in this location. Intraocular lenses cannot be felt or sensed in any way by the patient. Intraocular lenses never wear out and except in very rare instances, never need to be replaced.
Premium Lens Implants
Preparing for advanced intraocular lenses implant (IOL) cataract surgery is different than simply preparing for standard cataract surgery. These special lenses will need to be custom ordered prior to the surgery using the most accurate measurement of your visual requirements. It is important to consult with Dr. Stephenson prior to surgery to determine which lens type will fit your lifestyle the best.
