Expected Results With LASIK
If you and your doctor feel you did not achieve the expected results with LASIK, an enhancement surgery, which is a second surgery, may be performed. This can increase the odds of achieving good functional vision. This is usually necessary in about 10 to 18 patients out of 100. Patients with high degrees of nearsightedness, farsightedness, or astigmatism may be at a higher likelihood of needing an enhancement procedure to achieve their best possible vision.
Patients over the age of 40 may need or continue to use some form of reading glasses after LASIK because of a condition called presbyopia. Presbyopia is a normal, age-related decline in near vision that occurs in many people around the age of 40 years old. It is a natural process in which your lens loses its ability to bend. When this happens, you cannot read or do close-up activities, such as threading a needle, without using reading glasses -- even if you have the LASIK procedure. This decline in near vision occurs, regardless of whether you have LASIK.
Because individual situations can vary, if you have any questions about your expected results with LASIK surgery, you and your doctor can discuss your particular situation. It is important that your expectations match those of your doctor.
