The cornea plays a vital role in vision by functioning as the eye’s primary focusing element. As the clear, dome-shaped front part of the eye, it covers the iris, pupil, and anterior chamber, and its unique shape and transparency allow it to bend (refract) light rays. This refraction is essential for properly focusing light onto the retina at the back of the eye, which in turn sends visual signals to the brain.

In addition to its focusing capabilities, the cornea sendingacts as a protective barrier, shielding the inner structures of the eye from dirt, debris, and potential hazards. Its smooth, clear surface also helps maintain optimal visual clarity. Any irregularities or damage to the cornea can disrupt light transmission and cause vision problems, highlighting its importance in ensuring clear and accurate vision.

The cornea is a critical component of the visual system, acting as the eye’s primary focusing element and providing a protective barrier. Its role in refracting light and maintaining eye health is essential for clear, sharp vision.

Common Corneal Disorders

Common corneal disorders can be broadly categorized into ocular surface disorders, ectatic disorders, infectious disorders, and corneal degenerative and dystrophic conditions. Each category encompasses a variety of conditions that can affect the cornea’s health and function, impacting vision and overall eye wellness

Ocular Surface Disorders

Dry Eye Syndrome

A condition characterized by insufficient tear production or poor tear quality, leading to dryness, irritation, and discomfort.

Allergic Conjunctivitis

Inflammation of the conjunctiva (the membrane covering the cornea) due to allergic reactions. It can cause redness, itching, and swelling.


Inflammation of the eyelids that can affect the cornea and ocular surface, causing irritation and potential infection

Allergic Conjunctivitis

Inflammation of the conjunctiva (the membrane covering the cornea) due to allergic reactions. It can cause redness, itching, and swelling.

Chemical Injury

A condition where the stem cells located in the limbus (the area between the cornea and sclera) are damaged or depleted. This can lead to a breakdown of the corneal surface.

Ectatic Disorders


  • A progressive thinning and bulging of the cornea, resulting in distorted vision. It is often treated with specialized contact lenses, corneal cross-linking, or corneal transplant.

Pellucid Marginal Degeneration

  • A thinning of the cornea along its lower edge, causing irregular astigmatism and visual impairment.

Posterior Keratoconus

  • A rare condition where the back surface of the cornea becomes steepened, which may lead to visual distortion and require monitoring.

Corneal Transplants

Corneal transplants, also known as corneal grafts or keratoplasty, are surgical procedures that involve replacing a damaged or diseased cornea with healthy donor tissue. These transplants are performed to restore vision, alleviate pain, or improve the appearance of the cornea in patients with various corneal conditions.

Indications for Corneal Transplants

Corneal transplants may be indicated for a variety of conditions, including:

  • Corneal scarring due to injury or infection.
  • Keratoconus is a progressive thinning and bulging of the cornea.
  • Fuchs’ dystrophy, an inherited condition affecting the inner layer of the cornea.
  • Corneal degeneration or dystrophies that impair vision.
  • Persistent corneal swelling or clouding w
  • Failed previous corneal transplant.

Types of Corneal Transplants



Penetrating Keratoplasty 



Deep Anterior Lamellar Keratoplasty

Endothelial Keratoplasty

Endothelial keratoplasty is a type of corneal transplant that focuses on replacing the innermost layer of the cornea, known as the endothelium, while preserving the other layers. There are three main types of endothelial keratoplasty:
