1. Indications

The procedure of keratophakia is indicated for patients with specific refractive errors and conditions that affect visual acuity. The following are the explicitly provided indications for performing keratophakia:

• Aphakia - A condition characterized by the absence of the eye's natural lens, often resulting from cataract surgery or congenital issues.
• Myopia - Also known as nearsightedness, this condition causes difficulty in seeing distant objects clearly.
• Presbyopia - An age-related condition that leads to a gradual loss of the eye's ability to focus on nearby objects.
• Astigmatism - A refractive error caused by an irregular curvature of the cornea or lens, leading to blurred or distorted vision.

2. Procedure

The keratophakia procedure involves several critical steps to ensure the successful implantation of the donor corneal tissue. The following outlines the procedural steps as described:

• Step 1: Preparation of the Patient - The patient is positioned comfortably, and the eye is anesthetized to minimize discomfort during the procedure. The surgical area is then prepared to maintain a sterile environment.
• Step 2: Visualization of the Eye - An operating microscope is employed to provide a magnified view of the eye's structures, allowing the surgeon to perform the procedure with precision.
• Step 3: Peeling Back the Anterior Lamella - The surgeon carefully peels back the anterior lamella, which is the outer layer of the cornea, to create a pocket within the corneal stroma for the donor tissue.
• Step 4: Insertion of Donor Corneal Tissue - A piece of frozen donor cornea, previously shaped to the appropriate curvature for the patient’s specific refractive error, is inserted into the pocket created in the corneal stroma. Alternatively, an intraocular lens may be used.
• Step 5: Suturing the Implant - The donor tissue is secured in place using sutures to ensure stability and proper positioning within the cornea.
• Step 6: Post-Procedure Care - After the surgical steps are completed, the eye is typically covered with a patch or shield to protect the surgical site and facilitate healing.

3. Post-Procedure

Following the keratophakia procedure, patients are advised to follow specific post-operative care instructions to promote healing and ensure the best possible outcomes. The eye may be covered with a patch or shield to protect it from external irritants and to prevent accidental rubbing or pressure on the surgical site. Patients are typically monitored for any signs of complications, and follow-up appointments are scheduled to assess healing and visual acuity. It is essential for patients to adhere to prescribed medications, such as anti-inflammatory or antibiotic eye drops, to reduce the risk of infection and inflammation during the recovery period. The expected recovery time may vary, and patients should be informed about potential changes in vision as they heal.
