What Is Keratoconus?
Keratoconus is a progressive condition in which the cornea becomes thinner and more cone-shaped. This can cause irregular astigmatism, frequent prescription changes, glare and reduced visual quality.
Diagnosis
Corneal topography or tomography, pachymetry and a complete eye examination are used to assess shape, thickness and progression. Follow-up intervals depend on age and documented change.
Corneal Cross-linking
Cross-linking aims to strengthen the cornea and slow or stop progression in suitable eyes. Its main purpose is stabilization; additional visual correction may still be required.
Corneal Ring Options
Intracorneal ring segments, including synthetic segments or selected tissue-based options, may improve corneal shape in appropriate patients. Suitability depends on thickness, scar status and cone location.
Advanced Disease
Contact lenses may improve vision at different stages. In advanced disease with significant scarring or poor functional vision, corneal transplantation may be considered. Treatment is selected after detailed corneal analysis.
