What you are really asking is whether LASIK can correct both near vision and far vision and is it reasonable to consider another type of refractive surgery-Lens Replacement Surgery as an alternative to LASIK when correcting both far and near vision.
First, you need to understand a little about your eye problem and condition. If you are wearing bifocals to see BOTH near and far, it means that you have some distance vision problem such as nearsightedness, farsighted and astigmatism as well as presbyopia. Presbyopia is an eye condition that occurs because the crystalline lens in the eye loses its ability to flex and change focus, compromising your arms length and near vision. Presbyopia is a condition of the crystalline lens whereas nearsightedness, farsightedness and astigmatism are typically conditions of the cornea. Thus, the best treatments for presbyopia are often done by replacing the crystalline lens-so called lens replacement surgery. It is entirely possible that at 57 years old you have the very beginning of a trace of a cataract forming in your crystalline lens. Thus, by recommending Lens Replacement Surgery your eye surgeon is attempting to remove the crystalline lens and thus the future cataract problem, correct your distance vision and your presbyopia all in one procedure. This may in fact be the best recommendation. A good way to answer the question “Is Lens Replacement Surgery an option for me, is to find an eye surgeon who is both a cataract surgeon and a laser eye surgeon who will evaluate you and give you a second opinion on and guide you through the right decisions in selecting the best type of laser eye surgery or lens replacement surgery for you. The simple answer to the question “Which is better PRK or LASIK?, is to choose a reputable a laser surgeon who takes the time necessary to evaluate you properly and guide you through the right decisions in selecting the best type of laser eye surgery.
