Symptoms of keratoconus

The first symptom is usually the need for correction of vision, either with eyeglasses or contact lenses. When the disease progresses, visual acuity decreases both when looking at close and far distances, and vision impairment is especially pronounced in darkness. The patients can also develop photophobia (fear of bright light), decreased contrast of vision and “multiple” images around the object being looked at.

Keratoconus can be diagnosed with corneal topography investigation. A topographer is an instrument that provides three-dimensional atlas picture of the cornea by measuring the thicknesses and radiuses of the cornea in several locations. In our clinic we use two topographers: “Topolyser” – Wavelight Inc. and “Pentagam” – Oculus.
