Penetrating keratoplasty (PKP), also called a full-thickness corneal transplant or corneal graft, is a surgical procedure for treating severe corneal diseases. In this operation, the entire damaged cornea is removed and replaced with a healthy donor cornea.

Comprehensive Eye Examination: Your ophthalmologist will conduct a thorough eye exam to assess your cornea and overall eye health.

Corneal Size Measurement: Your corneal size will be precisely measured to ensure the donor cornea fits properly.

Medical Clearance: Additional tests, such as blood work, EKG, and chest X-ray, may be required to confirm your overall health is suitable for surgery.

Discontinuation of Certain Medications: You may need to stop taking medications like blood thinners before the surgery to reduce bleeding risks.

Mental Preparation: Prepare mentally for the surgery by discussing any concerns with your ophthalmologist and seeking emotional support.

Comfort and Pain Management: Your ophthalmologist will use either local anesthesia to numb the eye or general anesthesia to ensure no pain during the procedure.

Precision and Accuracy: A surgical instrument called a trephine creates a precise opening in the damaged cornea to remove diseased tissue.

Grafting and Suturing: A matched donor cornea is trimmed to fit and secured with fine sutures to ensure proper healing and integration.

Post-operative Care: After surgery, your eye will be covered with a protective bandage, and you will be prescribed antibiotics and anti-inflammatory drops to prevent infection and promote healing.
