If you want to have full femtosecond surgery at the age of 50, you need to choose whether you are suitable for full femtosecond surgery based on the state of your eyes and the advice of your doctor, and you should not judge from your age alone. The age requirement for full femtosecond myopia laser surgery is about 18 to 50 years old, because it requires a two-millimeter corneal incision to correct myopia. If you are over 50 years old, full femtosecond surgery is less recommended. This is because the body is in a state of aging after middle-age and old age, and the ability to heal and recover from surgery is reduced. And with age, the eyes may age and eye fatigue will become more and more obvious. If you have cataracts, cataract surgery and laser surgery may have conflicting issues, and you should also choose carefully whether or not to undergo surgery. Indications for full femtosecond surgery include myopia in the range of 300-1000 diopters. If accompanied by high astigmatism and poor corneal conditions, full femtosecond surgery is not suitable, depending on the judgment of the doctor. If the age of 50 years old, myopia is stable, there is no contraindication for surgery, such as glaucoma, diabetes and so on. The cornea thickness meets the requirements, combined with the doctor’s advice and guidance, the surgery can usually be performed. If you are at the age of 50 and are considering full femtosecond surgery, it is recommended that you consult your doctor in a timely manner, complete the relevant examinations, and choose whether or not to undergo full femtosecond surgery based on the condition of your eyes and in accordance with your doctor’s advice.
