How myopia surgery is done

When myopia surgery is performed, for patients with different degrees, the following methods can usually be taken to perform the surgery:

1. Below 1,000 degrees: corneal refractive surgery can be performed, and usually femtosecond laser surgery or excimer laser surgery can be performed to cut the corneal stroma layer and grind lenses to change the refractive state of the cornea, so as to make the patient's eyesight get effective improvement;

< p>2, more than 1000 degrees: crystalline lens IOL implantation can be performed, which can generally change the refractive state of the whole refractive system by implanting lenses to improve the patient's vision. The surgery can change the patient's entire refractive interstitium including cornea, aqueous humor, crystalline lens, and vitreous body, so that the refractive power is changed.

Keratoconus surgery and crystalline lens implantation are both safe and efficient ways to correct myopia. keratoconus surgery is recommended for patients with less than 1,000 diopters, and IOL implantation is an option for patients with more than 1,000 diopters. Both procedures can correct the patient's myopia status.
