If a cataract is truly not affecting your vision at all, you don't need to have anything done. Cataracts typically advance, but very slowly. So when it does become an issue for you, you can safely wait until then and still get the same good result. Are...

It would help to know more precisely what you mean by "corrective eye procedure." I presume you are referring to myopia/astigmatism correcting surgery (like LASIK) and not glaucoma or cataract surgery. If so, there are several procedures that can be done to correct...

Why do doctors put a lens in the eye after removing a cataract? Is it possible to remove a cataract without surgery? What are the chances of having a cataract again, after surgery? This question shows how we eye doctors could be doing a much better job educating our...
