Some patients have a lot of astigmatism, it is something they have had their whole life. This astigmatism may have made it difficult to wear contact lenses, and difficult to correct fully correct vision with glasses. Astigmatism is where the shape of the eye is out of round, more shaped like the American football. Unless astigmatism is corrected, it makes it difficult to see at distance and near!
Fortunately, now we can correct your astigmatism with a Toric Plus Lens, or astigmatism correcting implant lens. The result is less dependence on glasses for tasks that require clear distance vision such as driving, sports, or seeing the television. Unless you choose a bifocal/multifocal implant lens you will still need inexpensive reading glasses for near, but “readers” are much less trouble and expense than having to wear bifocals.
Strengths: good distance vision, good intermediate vision, corrects astigmatism, can wear over-the-counter readers
Weaknesses: will need “readers” for near vision
