Keratoconus is a noninflammatory dystrophy of the cornea, i.e. the transparent portion of the eye surface encountered by light rays entering the eye.
In this condition the cornea tapered (i.e. takes a conical shape) causing astigmatism and blurred vision. This condition occurs in both eyes during adolescence.
What are the symptoms of the condition?
- Increasing myopia
- Distortion of images
- blurred vision
Symptoms usually appear in late adolescence. The disease usually progresses slowly for 10 to 20 years and then stabilized. Starts, i.e., usually around 15, and continues until the 35 years.
To diagnose the condition used the technique of “topography of the cornea”, based on which we make the diagnosis even in subclinical forms, ie those who do not show symptoms. In particular, it gives us the position (height and width) of the corneal disorder, the range of kampylometrikis derogation and frequent tests the stability of the anomaly time .
At the same time, using the appropriate software simple topography can really help implement semi gas-permeable contact lenses. It behaves as a simulator application of a particular lens surface without the ‘hassle’ of the eye lenses that do not fit with this eye morphology.
What is the appropriate treatment?
The main treatment is the semi-hard contact lenses, and a proportion of patients can not be treated in this way leads to corneal transplant with a good prognosis.
- Glasses: Prescription glasses high astigmatism improves vision. The new refraction will be attempted by an ophthalmologist will almost always not fully satisfy the patient. The reason is that the deformation of the cornea is completely impossible to correct in every point with glasses.
- Contact lenses
- Surgery: The modern ophthalmology has made great strides in terms of radical treatment (therapeutic / invasive intervention) in keratoconus.
