Keratoconus (Corneal Diseases)
Keratoconus is the conical tapering of the normally rounded cornea (transparent layer of the eye) forward. It is a progressive and vision-impaired disease, usually starting in adolescence. Myopia and irregular astigmatism develop in patients with keratoconus. For this reason, patients cannot see the distance and the near very clearly. Eye degrees constantly increase and therefore frequent glasses change is required.
What Causes Keratoconus?
The cause of this disease is an imbalance of enzymes in the cornea. As a result, substances called "free radicals" cause oxidative damage in the cornea. Thus, the cornea becomes weaker and gives an anterior waist. Genetic predisposition is valid for this disease. For this reason, more than one keratoconus patient is frequently encountered in the same family. Among other reasons; ultraviolet rays of the sun, excessive eye rubbing, wearing contact lenses that do not fit the eye well and chronic eye irritation.
Treatment of Keratoconus
In the early and mild stages, glasses and soft contact lenses are sufficient to increase vision. However, as the disease progresses, the cornea becomes thinner and distorted; Glasses and soft contact lenses are not enough at this stage.
Keratoconus Treatment Methods:
- Corneal Cross-Linking
- Special Soft Contact Lenses
- Rigid Gas Permeable Contact Lenses
- Hard Gas Permeable Contact Lens On Soft Contact Lens (Piggyback Lens Application)
- Hybrid Contact Lens
- Scleral or Semi-Scleral Lens
- Corneal Ring (İntacs)
- Cornea Transplant (Keratoplasty)
