What are the dangers of laser surgery on the eyes

The eye hazards of laser surgery are overcorrection, undercorrection, glare, refractive error, dry eye, corneal disease and other complications, but they are generally rare and can be effectively controlled within a short period of time.
1. Overcorrection, undercorrection: that is, the corrected visual acuity is higher or lower than the expected visual acuity after surgery, usually due to the unreasonable design of the surgical program.
2. Glare: After laser surgery, the sequelae of glare, that is, the phenomenon of diffusion and superimposed shadow when seeing the light source, may occur, which can usually be gradually recovered with the increase of time.
3. Refractive regression: Refractive regression is also one of the sequelae of laser surgery, that is, the vision is abnormal again for a period of time after surgery, the specific time varies from person to person.
4. Dry eye: laser surgery is performed on the surface of the cornea of the eye, which will damage part of the corneal nerves, after the operation, some people may have or aggravate dry eye, dry eyes, foreign body sensation, photophobia, visual fatigue and other symptoms, which is also a relatively common sequelae.
5. Corneal diseases: Since laser surgery will act on the cornea, causing corneal damage, if you don’t pay attention to care after surgery, it may cause corneal epithelial hyperplasia, diffuse interlaminar keratitis and so on.
If you want to undergo laser surgery, you should choose a regular hospital to minimize the occurrence of surgical complications. After surgery, pay attention to eye care, follow the doctor’s instructions to standardize the use of medication, maintain eye hygiene, and visit the doctor on time for review.
