Keratectomy

Keratectomy is a surgical procedure used in ophthalmology to treat various corneal disorders. It involves the removal of a portion of the cornea, which is the clear, outer layer of the eye. The most common type of keratectomy is photorefractive keratectomy (PRK), which is used to correct vision problems such as myopia, hyperopia, and astigmatism. During this procedure, the cornea's outer layer is removed, and a laser is used to reshape the underlying tissue. After the procedure, the outer layer of the cornea naturally grows back. Keratectomy can also be used to treat other corneal conditions, such as scars or diseased tissue. In these cases, a larger portion of the cornea may need to be removed, and a corneal transplant may be necessary. Patients who undergo keratectomy may experience some discomfort and blurry vision for a few days after the procedure. However, these symptoms typically resolve relatively quickly, and patients can resume normal activities within a few days to a week. Ophthalmologists commonly use keratectomy procedures to help their patients with vision and other eye-related disorders. It is an effective and safe procedure, with minimal risk of complications. By choosing the keratectomy procedure, patients can expect to see a significant improvement in their vision and a better overall quality of life.
