I have worn a single +4 contact lense in my right eye for over 15 years. I am now struggling with a cataract. After biometry prior to lens replacement my surgeon was surprised to see that I have quite severe astigmatism. I want to end up with an implant so I can read without glasses (as I do at the moment with my contact lense) but am concerned that a toric lens will be the answer. The reason I say this is because for 15 years I have had no problem using the +4 contact and had no idea I had astigmatism in that eye. Any advice enormously appreciated.
