Corneal transplant surgery, also known as keratoplasty, is a procedure aimed at restoring vision by replacing a diseased or damaged cornea with a healthy donor cornea. While many patients experience significant improvements in vision post-surgery, it’s important to be aware of the potential complications that can arise. Understanding these complications can help patients make informed decisions regarding their eye health.

One of the most common complications following corneal transplant surgery is graft rejection. Graft rejection occurs when the recipient's immune system identifies the donor tissue as foreign and mounts an immune response against it. Symptoms may include redness, pain, light sensitivity, blurred vision, and a sensation of a foreign body in the eye. It is crucial for patients to recognize these signs early and seek immediate medical attention to address the issue.

Another potential complication is infection. Postoperative infections can affect the eye and the donor graft, potentially leading to serious vision loss if not treated promptly. Patients should be vigilant in monitoring for symptoms such as increased redness, discharge, pain, and swelling. Following the prescribed postoperative care, including the use of antibiotic eye drops, is essential for minimizing the risk of infection.

In some cases, patients may experience complications related to sutures. Suture-related issues can include the displacement or loosening of sutures, leading to astigmatism or improperly healing edges of the cornea. If patients notice any vision changes or discomfort, it is important to consult with their eye care professional for potential suture adjustment or removal.

Elevated intraocular pressure (IOP) is another concern after corneal transplant surgery. Increased IOP can occur due to various factors, including changes in the eye's structure following surgery or prolonged use of certain medications like corticosteroids. If not managed, elevated IOP can lead to conditions such as glaucoma, which may further jeopardize vision.

In rare instances, patients may experience retinal detachment post-surgery. This condition occurs when the retina becomes separated from its underlying supportive tissue, which can lead to significant vision loss if not addressed quickly. Symptoms may include sudden flashes of light, new floaters, or a shadow over the field of vision. Immediate medical intervention is critical for any signs of retinal detachment.

Additionally, patients may develop opacification (clouding) of the graft over time. Although this is more common in older individuals or those with certain underlying health conditions, it can impact visual acuity and may require further surgical intervention to restore clarity.

Emotional and psychological factors can also cause complications. The uncertainty related to surgical outcomes and the recovery process can result in anxiety and depression among some patients. Support groups or counseling can provide valuable assistance in navigating these emotional challenges.

In summary, while corneal transplant surgery can significantly improve vision for many patients, it is crucial to recognize the potential complications: graft rejection, infection, suture issues, elevated intraocular pressure, retinal detachment, and graft opacification. Regular follow-up with an eye care professional, adherence to postoperative instructions, and prompt attention to concerning symptoms can all contribute to a smoother recovery and better long-term outcomes for patients undergoing this procedure.
