The center guarantees that patients will be able to see perfectly after surgery. I don't know what to do. You generally can wait to have the surgery until your vision begins to bother you. If your doctor tells you that you have a cataract, ask whether you need surgery right away, what your risks are based on your general health, and what type of surgery may be appropriate for you, should you choose it. Be suspicious of any promotion promising completely successful, risk-free cataract surgery.
Cataract surgery has a very high success rate, but no surgery is free from risk.
Serious complications are rare, but when they do occur, they could result in loss of vision.
