Initial screening tests
Standard diagnostic workup

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Corneal Cross-Linking (CXL)
A minimally invasive procedure that uses riboflavin eye drops and ultraviolet light to strengthen corneal collagen fibers, slowing or halting keratoconus progression. This is considered the gold standard for preventing further corneal thinning and distortion.
Rigid Gas Permeable Contact Lenses
Specialized contact lenses that create a smooth refractive surface over the irregular cornea, significantly improving visual acuity in keratoconus patients. Requires proper fitting by an experienced eye care professional and regular follow-up visits.
Additional treatment options
Intracorneal Ring Segments (ICRS)
Small plastic arc-shaped segments surgically implanted into the cornea to flatten and regularize its shape, improving vision and potentially delaying the need for corneal transplantation. The procedure is reversible and adjustable.
surgicalRegular Corneal Topography Imaging
Serial imaging to map corneal shape changes over time, enabling early detection of disease progression and timely intervention. Typically performed every 3-12 months depending on disease severity and rate of change.
monitoringCorneal Transplant (Penetrating Keratoplasty)
Replacement of the diseased cornea with healthy donor tissue for advanced cases no longer manageable with other interventions. Requires prolonged recovery and lifelong monitoring for rejection signs.
