Question: I have just had cataract surgery and a toric lens implant for astigmatism in my left eye done. My cataract surgeon told me the lens had "rotated" about 10 degrees-how serious is this? Should I consider correcting this? How soon? I am doing my right eye next week.
Answer: It is possible to have a primary misalignment during the cataract surgery itself or in the unusual case a secondary rotation of the toric lens implant after the surgery. This is extremely rare with the Alcon AcrySof® Toric Lens Implant but is known to occur with other brands. In any event, there is no need to be concerned or to actually do anything to adjust the rotation unless it causes a problem with vision. A small rotation of 10 degrees-unless it is a very significant amount of astigmatism-should not typically cause too much vision disturbance. The best course of action is to follow the recommendation of your Cataract Surgeon.
