Corneal abrasions are a common eye problem in which the eye's cornea (an important part of the eye that allows light to enter properly) is scratched. In order to treat it, a doctor has to ...
Keratoconus is the most common grounds for conducting a penetrating keratoplasty, generally accounting for around a quarter of such procedures. [60] The corneal transplant surgeon trephines a lenticule of corneal tissue and then grafts the donor cornea to the existing eye tissue, usually using a combination of running and individual sutures.
Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness.EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy, is a corneal epithelial disease that may result in recurrent corneal erosions, irregular corneal astigmatism, and decreased vision.
The most common corneal disorders are the following: Corneal abrasion – a medical condition involving the loss of the surface epithelial layer of the eye's cornea as a result of trauma to the surface of the eye. Corneal dystrophy – a condition in which one or more parts of the cornea lose their normal clarity due to a buildup of cloudy ...
Keratitis is a condition in which the eye's cornea, the clear dome on the front surface of the eye, becomes inflamed. [1] The condition is often marked by moderate to intense pain and usually involves any of the following symptoms: pain, impaired eyesight, photophobia (light sensitivity), red eye and a 'gritty' sensation.

Dry eye syndrome is a common eye disease. [3] It affects 5–34% of people to some degree depending on the population looked at. [5] Among older people it affects up to 70%. [10] In China it affects about 17% of people. [11] The phrase "keratoconjunctivitis sicca" means "dryness of the cornea and conjunctiva" in Latin. [12]
Corneal surface irregularity and asymmetry are also caused by long-term contact lens wear; these problems are sometimes correlated with astigmatism in contact lens wearers and are thought to be caused by hypoxia, surface molding, and chronic and mild trauma to the cornea from contact lens use. [1]
(H52.2) Astigmatism — the cornea or the lens of the eye is not perfectly spherical, resulting in different focal points in different planes (H52.3) Anisometropia — the lenses of the two eyes have different focal lengths (H52.4) Presbyopia — a condition that occurs with growing age and results in the inability to focus on close objects
