Keratoconus is an eye condition characterized by the thinning and bulging of the cornea, resulting in irregular astigmatism and distorted vision. It usually starts during. teenage years or early adulthood and progressively worsens over time.
Keratoconus is a progressive eye disorder that affects the cornea, the clear front surface of the eye. In this condition, the cornea thins and bulges into a cone-like shape, resulting in distorted vision. Early detection and appropriate management are crucial for preserving vision and improving quality of life.
Symptoms
Blurred or distorted vision
Increased sensitivity to light
Eye strain & discomfort
Halos or ghosting around lights
Frequent changes in eyeglass prescription
Difficulty with night vision
Diagnosis
A comprehensive eye examination by an ophthalmologist or optometrist is necessary for a keratoconus diagnosis. Diagnostic tools may include:
Corneal topography
Visual acuity testing
Slit-lamp examination
Treatment Options
Eyeglasses and Contact Lenses: Mild to moderate keratoconus can often be managed with specialized eyeglasses or contact lenses designed for irregular corneas.
Advanced Contact Lenses: Scleral lenses, hybrid lenses, or rigid gas permeable lenses may be recommended for more severe cases, providing improved visual acuity and comfort.
Corneal Cross-Linking: This non-invasive procedure involves applying ultraviolet light and riboflavin (vitamin B2) to strengthen the cornea and slow down the progression of keratoconus.
Surgical Interventions: In advanced cases, corneal transplant surgery (keratoplasty) may be considered to replace the damaged cornea with a healthy donor cornea.
