Eye LASIK operation at 40 years old Many people in their 40s mistakenly think that it is too late for LASIK eye surgery and that they are no longer able to do glasses removal. However, the best age to perform refractive surgery is between 18 and 25 years old. But you should know that these operations are possible up to the age of 55 for people who are able to perform the operation in terms of eye examinations. What is certain is that if it is determined in your eye examinations that you have the conditions for **LASIK operation**, your age is no longer a criterion for performing the operation. People over 40 years old can also easily try their luck to perform LASIK and remove glasses. The beginning of eye aging Refractive surgery, including femtolysic, smile or PRK, corrects defects and improves vision by changing the shape of the cornea and correcting the corneal surface. The best results of LASIK surgery occur when the number of patients' eyes has not changed and has been stable for at least the last 6 months. Special considerations should be taken into account in patients over 40 years old. A vision problem that is usually seen in people 40 years old and older is presbyopia. . Around the age of 40, presbyopia symptoms begin in people. Presbyopia is a term that means that a person has poor vision to see near and has to use glasses. For people who have this problem, the near vision that is used for reading and studying becomes blurred. The gradual loss of flexibility of the eye lens causes the onset of presbyopia. Although patients over 40 years of age can fix their nearsightedness, farsightedness and astigmatism with Femto LASIK, Smile or PRK in the usual way, they still need to wear glasses for good and clear near vision after the operation. These operations can be useful and efficient after the age of 40 when a method called monovision is performed for your eye operation. **Read more:** **Exercise after glasses removal** ### What is monovision? Monovision means that one eye is corrected and treated for clear near vision and the other eye is treated for clear distance vision.
