If you require cataract removal surgery, choosing the right lens implant is an important decision for you and your doctor. The lens implant selection is the basis for optimum vision enhancement post surgery, and lifestyle improvement. In the past, patients had limited lens implant options to meet their visual needs. Today’s lens technologies now offer optimum natural-vision with premium lenses. 

The cornea is the clear front window of the eye and should be perfectly round – like the shape of a door knob. Astigmatism means that the cornea is slightly oval in shape – like the back of a spoon. If the cornea has significant astigmatism, then details such as print or street signs will appear blurred without glasses. Eyeglasses optically correct this blur by compensating for the oval shape of the cornea. 

In the past, when an artificial lens, called an intraocular lens implant, or IOL, was placed inside the eye during cataract surgery or lens replacement surgery, it did not have any power of accommodation. These IOLs are called single focus IOLs, and allow an eye to see either far away, or close-up, but not both.
