About Keratoconus Management
Keratoconus is a progressive condition in which the cornea, normally round and dome-shaped, becomes thin and begins to bulge into a cone-like shape. This distortion affects how light enters the eye, leading to blurred or distorted vision that cannot always be corrected with glasses alone. Early diagnosis and tailored management are essential to preserve vision and prevent progression.
At our clinic, we provide a comprehensive approach to keratoconus care, combining advanced diagnostic imaging with the latest therapeutic options. These include corneal collagen cross-linking (CXL) to stabilize the cornea and halt disease progression, custom contact lens fitting (such as scleral or hybrid lenses) for optimal vision correction, and corneal ring implants (Intacs) for reshaping and improving corneal regularity. In advanced cases, corneal transplantation may be considered.
Frequently Asked Questions
1. What are the early signs of keratoconus?
The most common early symptoms include blurred or distorted vision, frequent changes in glasses prescriptions, increased sensitivity to light, and difficulty seeing at night.
2. How is keratoconus diagnosed?
Diagnosis is made through a comprehensive eye examination, including corneal topography or tomography, which map the shape and thickness of your cornea with high precision.
3. Can keratoconus be cured?
There is currently no cure, but its progression can be effectively stopped with corneal collagen cross-linking (CXL), a minimally invasive procedure that strengthens corneal tissue.
4. What is corneal collagen cross-linking (CXL)?
CXL involves applying vitamin B2 (riboflavin) eye drops and then activating them with ultraviolet light. This process increases collagen bonds in the cornea, stabilizing its shape and preventing further thinning.
5. Will I still need glasses or contact lenses after cross-linking?
Yes, most patients still require vision correction, but their prescription often stabilizes after CXL, and vision can be significantly improved with specialized contact lenses.
6. What types of lenses are used for keratoconus?
- Options include rigid gas-permeable (RGP), hybrid, or scleral lenses. Scleral lenses are particularly comfortable and provide clear, stable vision by vaulting over the irregular cornea.
