In general, the risks of laser eye surgery for myopia include dry eyes, vision regression, glare, corneal complications, and reduced contrast sensitivity.
1. Dry eyes: Eye dryness commonly occurs after surgery, requiring long-term use of artificial tears; severe cases may affect vision.
2. Vision regression: In some individuals, vision may decline again after a period of time following surgery, possibly necessitating a second procedure.
3. Glare: In low-light or nighttime conditions, visual halos or blurriness may occur, affecting activities such as driving.
4. Corneal complications: Potential complications include corneal infection and displacement of the corneal flap, which may damage the cornea in severe cases.
5. Reduced contrast sensitivity: Decreased ability to distinguish between light and dark contrasts, resulting in diminished depth perception.
The risks of laser corrective surgery vary among individuals, and most complications can be minimized by selecting an experienced surgeon and following strict postoperative care instructions. Before considering such surgery, it is recommended to consult thoroughly with an ophthalmology specialist to understand individual risk factors and fully discuss all potential outcomes.
