How is Cataract Surgery Performed?
Cataract surgery involves removal of the cloudy lens, and replacement with an artificial lens, which is called an intraocular lens. The cataract is typically removed using ultrasound. I have had the opportunity to perform cataract surgery using a femtosecond laser, which may ultimately prove superior. It is too early to say at this point. Cataract surgery generally takes only a few minutes, and the success rate is extremely high.
For decades, the intraocular lenses we implanted after removing a cataract were of a fixed focus variety, meaning that they would focus on one point in space. Reading glasses were required for near and intermediate vision with these older intraocular lenses. Newer intraocular lenses have the ability to see well at near as well as distance. Examples of these lenses include the Crystalens, Tecnis Multifocal and Restor. Each of these lenses has unique advantages. There are endless good and bad sources of information available on-line regarding these lenses, but nothing can substitute for a thorough consultation with your surgeon.
