A non-inflammatory, bilateral, ectatic disorder where the central cornea progressively thins, causing it to bulge outward and form a round, irregular cone in early puberty. Due to the cornea's abnormal shape, the light entering the eye is prevented from being focused on the retina, leading to distorted vision (irregular astigmatism) and an increase in myopia. Glasses and soft contact lenses eventually do not correct vision requiring solutions like rigid gas permeable contact lenses or keratoplasty (mainly when corneal scarring occurs).
