What are the different types of implants now available?
We insert a tiny plastic implant into the eye at the time of cataract surgery. Without an implant, your vision would be quite blurred after surgery and you would require thick glasses or contact lenses to see, which is the way cataract surgery was done years ago. There are now three basis types of implants: Standard, Multi-focal or Toric. Your options vary depending on whether you have astigmatism or not. Astigmatism occurs when the front part of the eye is curved or football shaped as opposed to being round or baseball shaped.
If you have astigmatism (a football shaped eye), you may want to consider having a Toric lens implant inserted at the time of your cataract surgery. Many people do not realize that they have astigmatism as it was always been corrected with glasses. Others think that their astigmatism is extreme but it is only moderate. We let you know at the time of your cataract consultation if your astigmatism is enough to benefit from a Toric implant. If you do have significant astigmatism and you elect to have a Standard implant inserted at the time of cataract surgery, your distance vision will be blurred without glasses after the procedure.
Whether you have astigmatism or not, you can now benefit from the placement of a Multi-focal lens implant at the time of your cataract surgery. Multi-focal implants have the advantage of allowing you to see close-up for reading; far-away for driving and golf; and intermediate distances for computers and cooking. It is kind of like "turning back the clock" to the days before you needed reading glasses in your 40's. The two types of Multi-focal implants we current use are the Alcon ReSTOR implant and the AMO Tecnis Multi-focal implant. In the past the multi-focal implant was only available for those without astigmatism ("baseball eyes") but now is available for those with astigmatism ("football eyes") in a combination Toric/Multi-focal lens.
Both the Multi-focal and Toric implants have been well accepted by thousands of area residents who now see better than ever after their cataract surgery. You will learn more at the time of your cataract consultation to help you decide which implant option is best for you.
