Keratoconus in Oman — everything you need to know in one place

? What is keratoconus?

Keratoconus is a condition that affects the cornea — the clear front layer of the eye. The cornea gradually becomes thinner and bulges forward into a cone shape instead of its normal round curve. This change in shape scatters the light entering the eye, so vision becomes blurred and distorted.

It often begins in the teenage years or twenties and may progress slowly over years. The reassuring news: with early detection and follow-up, its progression can be halted and good vision preserved.

1 Symptoms to watch for

• Blurred, distorted vision that isn't fully corrected by glasses.
• Frequent changes to your glasses prescription over short periods.
• Halos and starbursts around lights, especially at night.
• Noticeably poor night vision.
• High, irregular astigmatism.
• Light sensitivity and glare, sometimes with itching and frequent eye rubbing.

2 How do we diagnose keratoconus?

Accurate diagnosis relies on a specialist exam including corneal topography / tomography — imaging that measures the curvature and thickness of the cornea with high precision and reveals early changes even before symptoms are obvious.

Early detection matters greatly, because it opens the door to halting the condition before it advances — and this is where a specialized center with modern equipment makes all the difference.

3 Treatment options (depend on the stage)

• Early stages: glasses or soft contact lenses to correct vision.
• Corneal cross-linking (CXL): a procedure that strengthens the cornea's bonds and stops the disease from progressing. It doesn't reverse existing damage but prevents it from worsening — so it's recommended early when there is active progression.
• Rigid and scleral lenses: to correct vision when glasses are no longer enough.
• Intracorneal ring segments: to improve corneal shape in selected cases.
• Corneal transplant: a last resort reserved for very advanced cases only.

4 Scleral lenses — clarity and comfort

Scleral lenses are large-diameter rigid lenses that rest on the white of the eye (the sclera) and vault over the cornea without touching it, creating a reservoir of fluid between the lens and the cornea.

This design delivers sharp, comfortable vision even on irregular corneas, and is one of the best solutions for advanced keratoconus patients for whom glasses or standard lenses no longer work. At our center we measure and fit the lens specifically to your eye and follow up with you after delivery.
