Corneal Surgery

Corneal Surgery

Diseases of the Cornea and Anterior Segment of the eye are increasing in prevalence. As we age, the incidence of age-related corneal degeneration increases, and corneal diseases are a significant cause of blindness in both developed, and developing countries. Fortunately, developments in surgical technique and ophthalmic technologies now allow us to successfully treat many blinding corneal conditions. Current forms of Corneal Transplantation, Artificial Cornea Surgery, Artificial Iris Surgery, and Pterygium Surgery can now be performed with less complications and good success rates.

The Cornea

The cornea is the clear transparent window at the front of the eye, allowing light to focus and enter the eye. If the cornea is damaged or distorted by injuries or infection, or becomes cloudy due to various corneal diseases, vision may be significantly reduced, or lost. The cornea has several layers consisting of different tissue layers – some corneal diseases affect only inner or outer layers, while other corneal diseases may affect all the layers of the cornea.

Corneal Transplantation

Corneal Transplantation is a surgical procedure, in which the diseased layers of the cornea are replaced by healthy donor corneal tissue donated by another individual when he or she passes away. The replacement of the cloudy cornea, with a clear and healthy new cornea, restores vision to the corneal transplant patient.

Current forms of Corneal Transplantation

The Cornea consists of several layers, and in many patients, not all the layers are diseased or damaged. In the past, corneal surgeons only performed one main procedure – the Penetrating Keratoplasty (PK) operation, whereby the entire central aspect of the cornea was replaced by a donor cornea – a full-thickness transplant.

Artificial Cornea Surgery

Corneal transplantation may not be the ideal treatment for some of the more severe corneal diseases. In some patients, who have previously had failed corneal transplants, and in some severe cases of chemical or thermal injuries affecting the cornea, in certain severe dry eye or inflammatory states, an Artificial Cornea (otherwise known as a Keratoprosthesis, or KPro) may be indicated.

Pterygium Excision with Conjunctival Autograft
New Forms of Pterygium Surgery

The current innovation in pterygium surgery is Conjunctival Autografting using Fibrin Glue – this procedure uses fibrin glue to attach a conjunctival graft (taken from under the eyelid) in pterygium excision – this procedure has the lowest rate of recurrence of the pterygium (in the region of 1-2%), provides a good cosmetic result, and is sutureless surgery, which reduces patient comfort after surgery.
