Ask an Eye Doctor and Get an Answer ASAP
Hello and thanks for your question. Are you available to chat?
What you're referring to is called a refractive lens exchange. If your lenses are now cataracts, then the same procedure is done but called cataract surgery. The procedure involves making two small incisions in the eye (3mm and 1mm) and using a small ultrasound probe, to gently break up your lens and vacuum it out. An artificial intraocular lens implant (IOL) would then be implanted in its place. There are newer lenses on the market these days that allow a person to have relative glasses independence at near, intermediate and far distances--they can be a bit pricey, but many people swear by them for the independence they get from spectacles. Can this surgery make dry eye worse? Yes, but usually the effect is transitory and not long-lasting. As long as the dry eye is well controlled and given appropriate attention after the surgery, it usually is not permanently made worse. Does this help answer your question?
