Corneal Collagen Crosslinking with Riboflavin (CXL) Corneal collagen crosslinking is a safe, minimally invasive procedure designed to stabilize and strengthen the cornea in patients experiencing progressive keratoconus or corneal ectasia. The procedure involves applying riboflavin (Vitamin B2) eye drops combined with controlled ultraviolet (UV-A) light exposure to reinforce corneal fibers. Procedure Steps: Preparation: The eye is numbed using topical anesthetic drops to ensure patient comfort. Epithelium Removal (if applicable): The corneal surface layer (epithelium) may be gently removed to allow optimal riboflavin absorption. Riboflavin Application: Riboflavin drops are applied at regular intervals for approximately 30 minutes to saturate the cornea. UV-A Exposure: The cornea is exposed to controlled UV-A light for around 10-30 minutes, activating the riboflavin to facilitate collagen crosslinking. Completion: A protective contact lens may be placed to promote healing and comfort post-procedure. Recovery: Patients typically experience mild discomfort, sensitivity to light, and blurred vision initially, but these symptoms usually improve within a few days. Prescribed eye drops are used to aid healing and prevent infection. Benefits: CXL significantly slows or stops keratoconus progression, preserves vision, reduces the risk of corneal transplantation, and improves overall corneal stability. Risks: Although generally safe, potential complications include temporary irritation, light sensitivity, corneal haze, or infection. Such complications are rare and usually manageable.
