Cornea - Our Service

About Cornea

The cornea, a transparent and domed structure at the front of the eye, is nothing short of remarkable. It serves as the eye's primary focusing lens and plays a pivotal role in vision. At Global LASIK Laser Center, we recognize the significance of the cornea in maintaining clear and healthy vision. Let's delve into the world of the cornea and understand its crucial role in our eye care services.

The Cornea's Role in Vision

Imagine the cornea as the eye’s clear window, responsible for allowing light to enter and refracting it onto the retina. This process is fundamental for clear and sharp vision. The cornea is uniquely designed to provide two-thirds of the eye’s focusing power, with the crystalline lens in the eye providing the remaining third.

Common Vision Problems and the Cornea

Many common vision problems, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, are directly related to the cornea’s shape. These conditions occur when the cornea’s curvature is irregular, causing light to be improperly focused on the retina. Vision correction procedures, including LASIK, PRK, and LASIK with C3R, often involve reshaping the cornea to address these issues.


LASIK (Laser-Assisted In Situ Keratomileusis)


  • LASIK adjusts the cornea’s curvature using a precise laser, allowing light to be accurately focused on the retina.
  • This reshaping of the cornea is customized to each patient’s specific vision needs, resulting in clear vision without the need for glasses or contact lenses.


  • PRK also reshapes the cornea’s surface to correct refractive errors.
  • Unlike LASIK, PRK involves removing a thin layer of the corneal epithelium before laser treatment, making it suitable for individuals with thinner corneas.

PRK (Photorefractive Keratectomy)


C3R (Corneal Collagen Cross-Linking)


  •  LASIK with C3R combines LASIK’s vision correction capabilities with corneal strengthening through C3R.
  •  The corneal collagen cross-linking enhances corneal stability, making it an ideal choice for those with thin corneas or a predisposition to corneal disorders like keratoconus.

The cornea’s role in vision is undeniable, and its unique properties make it a central focus in eye care and vision correction.
