At present, the possible sequelae of myopia surgery are:
1, corneal flap eccentricity, angular flap misalignment, corneal flap wrinkle, corneal interlayer debris or blood residue.
2. The laser cutting is off center, and the corneal knife cuts through the cornea.
3, postoperative lifelong glare and glare: myopia is more common in high altitude areas, seeing things with halo.
4. Undercorrection or overcorrection: This situation will be reoperated, which is not ideal after reoperation.
5, vision rebound: especially for people with high myopia, vision began to decline a few years after surgery.
6, the best corrected vision decline: after surgery, the vision that can be achieved when wearing glasses can not be achieved.
7, reading difficulties, dry eye, decreased corneal sensitivity, pain.
8. Irregular astigmatism: Almost all people who have myopia surgery have different degrees of irregular astigmatism after surgery.
9. Corneal infection, diffuse interlaminar keratitis and formation of central corneal island.
10, corneal peripheral degeneration or scar formation, corneal central pigmentation.
Although myopia surgery has been developed for 20 years, the technology is very mature, but because it is surgery after all, the postoperative influence can not be completely eliminated at present, so surgery is generally not recommended.
To avoid surgery, it is best to find myopia and treat it in time. Experts suggest that early myopia can be well controlled or improved as long as bad eye habits are corrected in time and eye-pleasing nutrients are taken orally, and it can be well controlled or improved for a period of time, and there is no need for surgery in adulthood.
