Keratoconus is a condition where the cornea thins and bulges into an irregular cone shape and this can distort vision over time if not monitored. Corneal Collagen Cross-linking or simply C3R or CXL is a procedure that is meant to prevent this progression at an early stage. Cornea Specialist, Indore, Dr. Birendra Jha uses cross-linking to maintain the stability of the cornea before it calls for further advanced intervention.

What is Corneal Cross-linking (C3R/CXL) ?

Corneal Collagen Cross-linking is a procedure that thickens the cornea by increasing the number of molecular bonds (cross-links) between the collagen fibers in the corneal tissue. It is done by applying riboflavin (vitamin B2) drops to the cornea and then activating them with a controlled dose of ultraviolet-A (UV-A) light, which triggers the formation of new bonds and stiffens the corneal structure.
The main objective of cross-linking is not to undo existing corneal distortion but to halt or substantially slow down the progression of diseases such as keratoconus, retaining as much of the patient’s current visual acuity and corneal shape as possible.
Cross-linking for treating conditions

Indications of Cross-linking (C3R/CXL) in Indore are mainly:

• Progressive keratoconus, especially in younger patients where the disease tends to progress faster
• Pellucid marginal degeneration, which is a different type of progressive thinning of the cornea
• Corneal ectasia after LASIK, a rare complication of refractive surgery
• Some cases of corneal thinning detected early by routine screening topography

Signs That Could Indicate Progressive Corneal Thinning

If you see immediately consult an eye specialist in Indore

• Spectacle power rapidly deteriorating or frequently changing
• Increasing astigmatism not completely correctable with glasses
• Seeing clearly or seeing things clearly, especially in the nite
• Increased light and glare sensitivity
• A family history of keratoconus with your vision changing rapidly
• Rubbing the eyes frequently, which is associated with progression of keratoconus

Diagnosis of Progression Prior to Cross-linking

Diagnosis is based primarily on corneal topography, which provides a detailed map of the curvature of the cornea, and pachymetry (measurements of corneal thickness). Serial topography scans over several months are often used to confirm that the condition is truly progressing, an important factor in determining whether cross-linking is indicated.

The Cross-linking Process

Cross-linking is usually done as an outpatient procedure. Riboflavin drops are applied on the cornea for a period of time to achieve adequate saturation and then exposed to a timed dose of UV-A light under controlled clinical conditions.
The procedure can be performed as (based on the particular case):

• Epithelium-off (standard) cross-linking — the thin outer layer of the cornea is removed to allow better penetration of riboflavin
• Transepithelial (epithelium-on) cross-linking — a milder form used in selected cases
• Combined with cross-linking with other procedures such as Topo-Link C3R for topography guided treatment

Recovery usually includes a regimen of eye drops, temporary light sensitivity and mild discomfort for a few days. Regular follow-up with topography confirms that the cornea is stable as planned.

Why Niramay For Cross-linking 

Dr. Birendra Jha, a cornea specialist in Indore, stresses the importance of early diagnosis of progressive corneal disease, since cross-linking works best before the cornea thins significantly. For patients, serial topography monitoring is a great advantage in that it objectively verifies if and when they actually need treatment.
