Keratoconus – ICRS, CCL
In the case of keratoconus, retina is bulged into a conical shape. Keratoconus is a retinal disease during which the retina is slowly but permanently becoming more and more conical and thin. This is the cause of the increase of short-sightedness and of the development of irregular astigmatism. It occurs around 20 years of age. The disease develops for many years, often 10 or 20 years.
It is difficult to correct the condition with glasses. Sometimes hard contact lenses can help. In the last phase of the disease, the cornea becomes cloudy and its transparency is limited.
Previously, the only solution was corneal transplantation. Today we can put off the transplantation by means of ICRS and CCL techniques.
ICRS and CCL are not covered with health insurance companies. The price of the ICRS surgery is CZK 34 thousand, price of CCL is CZK 16 thousand
Your questions
- What is keratoconus?
Slowly but permanently, the cornea is becoming more and more conical and thin.
This causes the progression of the short-sightedness and the occurrence of irregular astigmatism.
It is difficult to correct the condition with glasses, sometimes hard contact lenses can help.
In the last phase of the disease, the cornea becomes cloudy and its transparency is limited.
Previously, the only solution was corneal transplantation. - Can keratoconus be treated?
Keratoconus cannot be completely cured. We can provide efficient aid, though.
It is possible to flatten the improper and irregular curve of the cornea in keratonus and to stabilize it by implanting special plastic segments (kerarings). They are abbreviated as ICRS - Intrastromal Corneal Ring Segments.
It is possible to strengthen and stabilize the corneal tissue by means of the CCL method - Corneal Cross Linking. - What is ICRS?
ICRS - Intrastromal Corneal Ring Segments, sometimes also referred to as Keraring - is a method during which the improper and irregular curve of the cornea in keratoconus is flattened and stabilized by implanting special plastic segments.
- Do you implant “rings”, “segments”, “kerarings”?
Yes, we do. We use ICRS - Intrastromal Corneal Ring Segments to stabilize eye keratoconus.
- What is CCL?
CCL or Corneal Cross Linking (sometimes also CXL) is a method of strengthening the cornea.
By combining riboflavin and selective ultraviolet rays, we can create strengthening linkages among the individual molecules of the corneal tissue.
Thus the corneal tissue becomes stronger and more resistant.
It is particularly used in keratoconus and pellucid marginal degeneration. - Is it true that keratoconus can be treated with radiation therapy?
Yes, it is. But it is not ionizing radiation.
The cornea is exposed to the ultraviolet light that creates strengthening linkages among the individual molecules of the corneal tissue by means of substance called riboflavin.
Thus the corneal tissue becomes stronger and more resistant.
It is particularly used in keratoconus and pellucid marginal degeneration.

Ophthalmologist after PRELEX
Even though I've been involved with multifocal intraocular lenses for over 20 years, it is amazing what I've been able to learn in the past three weeks from my own experience with having multifocal lenses in my eyes. (PRELEX with Alcon Acrysof Restor Multifocal lens)
The decision to travel to NeoVize EyeClinc and to heve the laser surgery there was one of my best decisions in my life.
