The disadvantages of LASEK surgery, which is known as quasi-molecular laser subepithelial keratomileusis, are slow recovery, postoperative pain, and the possibility of subepithelial corneal clouding. There are many advantages of this surgery, which brings the hope of correction for some patients with ultra-high myopia and relatively thin corneal thickness; however, there are also some disadvantages as follows: 1. Slow recovery: it usually takes about one week after the operation to recover normal vision, the recovery time is longer, but the recovery time also varies from person to person. 2. Post-operative pain: usually about three days after the operation, the pain is lighter than laser optical keratomileusis, but heavier than excimer laser surgery pain. 3. Complications: LASEK surgery patients may have corneal subepithelial turbidity (HAZE), generally the younger the patient, the higher the degree the more likely to have corneal subepithelial turbidity. Currently, there are many types of laser surgery used to correct myopia. Patients are advised to consult with a specialist to weigh the pros and cons before choosing the right type of surgery.
