Who can talk about the harm of laser myopia surgery?

1, dry eye: users of refractive surgery have a higher probability of dry eye than normal people, and some people may need to use artificial tears for life.

2, keratoconus may appear: because refractive surgery will make the cornea thinner, for some special patients, the thin cornea will gradually protrude forward under the pressure in the eye, thus forming keratoconus. At this time, patients will have progressive myopia and irregular astigmatism that is difficult to correct, so their vision will deteriorate and even undergo corneal transplantation.

3. Corneal infection: Any traumatic operation has the risk of infection. Once infection occurs, it may seriously affect the patient's vision, but the probability of such harm is small.

4. Laser surgery may affect the intraocular pressure measurement of users: corneal thickness has obvious influence on intraocular pressure measurement. When the cornea becomes thinner, its measurement may not truly reflect the actual intraocular pressure. Therefore, people with glaucoma tendency or family history should carefully choose this operation.
