Keratophakia is a specialized surgical procedure classified as a type of keratoplasty, which involves the transplantation of corneal tissue. In this procedure, a piece of frozen donor cornea is meticulously shaped to achieve the desired curvature that is specific to the patient's refractive error. The primary goal of keratophakia is to correct refractive errors and enhance visual acuity in patients suffering from conditions such as aphakia (absence of the lens), myopia (nearsightedness), presbyopia (age-related loss of near vision), and astigmatism (irregular curvature of the cornea). During the operation, an operating microscope is utilized to provide a detailed view of the eye's structures. The anterior lamella, which is the outer layer of the cornea, is carefully peeled back to create a space for the donor corneal tissue implant. This reshaped donor tissue, or alternatively an intraocular lens, is then positioned deep within the corneal stroma and secured in place with sutures. Following the completion of the procedure, it is common practice to cover the eye with a protective patch or shield to promote healing and protect the surgical site.
