Lamellar keratoplasty is a type of eye surgery that involves replacing a portion of the cornea, the clear front surface of the eye. This procedure is often used to treat conditions like keratoconus or corneal scars, where only a part of the cornea is affected. By removing the damaged layer and replacing it with healthy tissue, vision can be improved while preserving the surrounding corneal structure. During the surgery, the surgeon carefully removes the affected layer of the cornea and replaces it with a donor graft. This technique allows for faster recovery and less risk of complications compared to full-thickness corneal transplants. Lamellar keratoplasty can be performed using various methods, including microkeratome or femtosecond laser technology, depending on the specific needs of the patient.
