What to do if corneal perforation occurs

Everyone is familiar with the cornea. Once it is affected, it will cause vision obstruction and even make you unable to see anything anymore. This is a very painful problem. But what if corneal perforation occurs? Corneal perforation can cause blindness. The options include penetrating corneal transplantation or artificial cornea transplantation, but in general, corneal transplantation is a better choice.

1. What to do if corneal perforation occurs

1. Penetrating corneal transplantation

Penetrating keratoplasty is a procedure that replaces the entire thickness of the cloudy and diseased cornea with a fully transparent cornea. Indications can be divided into optical, therapeutic, plastic, and cosmetic aspects according to the purpose of surgery. Common indications for optical keratoplasty include keratoconus, corneal scars caused by various reasons, various corneal dystrophies, and corneal endothelial cell failure caused by various reasons.

2. Lamellar keratoplasty

Lamellar keratoplasty is a partial-thickness corneal transplant. During the surgery, only the diseased tissue in front of the cornea is removed, and then a partial-thickness transparent cornea donor is transplanted to repair the removed area. The chance of immune rejection after surgery is low. It is commonly used clinically to treat middle and superficial corneal opacities, corneal dystrophic opacities, keratoconus, middle and superficial corneal infections, corneal tumors, etc.

3. Artificial corneal transplantation

Artificial corneal transplantation is a surgical method in which a special optical device made of transparent medical polymer material is implanted into the corneal tissue to replace part of the corneal scar tissue and restore vision. Since problems such as corneal tissue rejection of artificial synthetic materials have not been resolved, the long-term effect is poor, often causing aqueous humor leakage at the transplant site and shedding of the transplant, so it is not possible to use it widely at present.

Complications of corneal transplantation

1. Rejection reaction: All tissues transplanted to others may be rejected;

2. Various eye infections;

3. Glaucoma;

4. Loosening of corneal sutures;

5. Refractive error after surgery.
