This is a private hospital. A professional eye hospital is better. There are many surgical treatments for myopia, including corneal refractive surgery and intraocular refractive surgery, and the operation time is not the same. Excimer laser surgery and femtosecond laser surgery usually don't take too long, and they can be completed in about 10 minutes. Intraocular refractive surgery is similar to cataract surgery, so the operation time is relatively long, which usually takes about half an hour. Different operators may have slightly different time due to different proficiency. But this kind of operation is a very delicate operation, so we must go to a regular hospital for examination and diagnosis.
