Q: After excimer laser surgery, will myopic patients still experience retinal degeneration, lacunae and detachment? A: The risk of retinal cracks and detachment in myopic patients is higher, mainly due to the long eye axis and the relative weakness of the retina, which has no obvious relationship with the surgery. Although patients do not need to wear glasses after excimer laser surgery, the condition of the retina at the bottom of the eye has not been improved by the surgery. Therefore, postoperative myopic patients may still have retinal lesions. Therefore, it is recommended that post-surgery patients have their fundus examined regularly for early preventive treatment.
