A surgical procedure known as epithelial debridement is conducted to loosen and separate the outermost layer of the cornea, called the epithelium. Following the loosening process, the loosened epithelial layer is carefully lifted away from the cornea, creating access for laser ablation. Laser ablation involves the use of a laser to reshape the cornea, correcting refractive errors such as myopia, hyperopia, or astigmatism. This precise surgical technique aims to enhance the focusing ability of the eye and improve visual acuity. By performing epithelial debridement and subsequent laser ablation, patients can achieve clearer vision and reduce their dependence on corrective lenses.
