New Adhesive May Aid in LASIK Safety

Researchers at Kansas State University have developed a new adhesive with the goal of reducing risks in LASIK surgery. Research shows that a new protocol that involves using ultraviolet light, fibrinogen, and riboflavin may improve the glue to keep the corneal flap in place.

According to those involved in the research, the best corneal flap adhesion is a glue created with the combination of riboflavin and fibrinogen, and then adding binding proteins and ultraviolet light. The ultraviolet light is the same kind used in tanning salons. This is also a nontoxic biodegradable glue used during cataract surgery.

The flap detaching from the cataract is a major risk after LASIK surgery because, once the lens is cut to get to the cornea to be reshaped, the attachment between the cornea and the surface is permanently weakened. If an accident occurs and the flap is knocked loose, the cornea itself can be contaminated, which may result in the need for a corneal transplant.

Although corneal transplants, which replace just a part of the existing cornea, are the most common type of organ transplant, and are a routine outpatient procedure, the Mayo Clinic reports nearly 20 percent of them fail. So, chalk up corneal transplant as an outlier risk of LASIK surgery.

A second study analyzed reactions of the glue at the molecular level to see exactly how the adhesion works. There is hope the glue can be further developed for applications in different medical treatments throughout the body.
