Karataconus is the thinning and sharpening of the cornea. In keratoconus patients, the amount of corneal angle increases gradually as a congenital feature, and this results in cornea protrusion. With the increase in the cornea’s forward bulge, astigmatism occurs. Keratoconus disease has different stages, which are mild (stage 1), middle (stage 2), advanced (stage 3), and severe (very advanced). The first sign of keratoconus is blurred vision. Among the complaints are increased light sensitivity, glare, diminished night vision, headache, difficulty in reading, double vision, burning, stinging and redness. The quality of life of the patients in this group falls, and the visual quality may be affected at a later stage.

Keratoconus is usually a disease that affects both eyes, but one eye can be more affected than the other.

Equal female / male ratio. Keratoconus is often recognized in youth ages, rarely in the twenties and sometimes in later stages of life.

Changing and increasing astigmatism in every eye examination should suggest keratoconus disease. If the disease is left untreated, the cornea becomes extremely thin (severe keratoconus), and the vision of the patient is diminished by edema and turbidity.

Contact lenses are used in corneal cross-linking, intra-corneal rings, corneal transplantation, keratoconus treatment.

Contact lenses are used in corneal cross-linking, inra-corneal rings, corneal transplantation, keratoconus treatment.

Soft contact lenses are more suitable for patients with keratoconus because soft contact lenses and glasses can not completely correct the irregular structure of the eye’s surface. However, contact lenses of this type are also more difficult to use, and patients are not always comfortable. It requires patience and care by both the patient and the doctor.

Increasing the internal bonds of the corneal layer using riboflavin in ultraviolet and drop form and making the cornea more resistant. The purpose of this treatment is to stop the ongoing keratoconus disease.

Corneal ring is one of the recently developed treatment methods for keratoconus patients. Two small, semi-circular pieces that are viewed as transparent are placed in the cornea. The corneal rings do not stop the progression of keratoconus, and temporarily correct the visual impairment caused by keratoconus disease.

20% of keratoconus patients need corneal transplantation. Corneal transplantation is the surgery to replace the central 7-9 mm section of the cornea. Corneal transplant surgery may be an inevitable end to late-onset keratoconus patients. Although success in this surgery is reported as 95%, it rarely involves serious complications.
