What Are My Options for Contact Lenses for Keratoconus?
Keratoconus is a chronic disease of the cornea, in which it loses its ability to maintain its spherical shape, becomes thin, stretches, becomes cloudy, and does not perform its natural functions.
Without treatment, the disease leads to a progressive decrease in visual acuity, up to blindness.
Often the first complaint we will look out for here at EyeDrs is decreased vision, inability to improve visual acuity with the usual glasses or lenses, and frequent changes of glasses. We also check for any noticeable glare, flashes, distortion of objects, foggy images, redness, and dry eyes.
Further symptoms can be recognized by the doctor during the examination which depends on the degree of keratoconus development:
- Astigmatism – the disease impairs the eye’s ability to focus light rays on the retina, increases pre-existing astigmatism, and increases the corneal refractive power.
- Thinning of the stroma (basic substance) of the cornea in the center, conical bulging forward.
- at corneal microscopy – cracks in the descemetal membrane.
- Superficial and then deep stromal scarring;
- In the terminal (final) stages – protrusion of the lower eyelid when looking downward (Munson’s symptom), ring-shaped deposition of gland in the epithelial layer around the cone (Kayser-Fleischer ring).
