Can corneal cross-linking surgery cure keratoconus?

Corneal cross-linking surgery cannot cure keratoconus, but it can effectively slow disease progression, stabilize corneal shape, and prevent further vision deterioration. It is currently an important method for controlling keratoconus. If keratoconus progresses rapidly, vision drops suddenly, or there is risk of corneal perforation, prompt medical attention is recommended.

Keratoconus is a degenerative condition in which the cornea gradually thins and bulges forward. Cross-linking surgery uses ultraviolet light in combination with riboflavin to enhance the cross-linking of corneal collagen fibers, increasing corneal rigidity and stability, thereby preventing further corneal thinning and protrusion and controlling disease progression.

This procedure cannot reverse existing corneal shape changes or vision damage, nor can it replace corrective methods such as glasses or contact lenses. It is not suitable for patients with advanced keratoconus or those with severely thinned or perforated corneas, who may require corneal transplantation.

After surgery, patients should use anti-inflammatory eye drops as prescribed, avoid rubbing the eyes and any ocular trauma, maintain good eye hygiene to prevent infection, attend regular follow-up appointments to monitor corneal shape and vision, and avoid prolonged eye strain and strenuous physical activity to protect the eyes and promote recovery.
