CORNEA SERVICES TO PROTECT
VITAL PART OF THE EYE
The outer layer at the front of your eye is the cornea. It helps to focus on the light so that you can see properly. Well!! As per the specialist, the length of the cornea ranges around 12 millimeters in length and 11 millimeters in height. When the light passes through the dome-shaped cornea, it helps to bend the light and thus helping the eye to focus on a specific object.
The cornea is one of the sensitive tissues of the body. A change in the shape of the cornea causes several refractive problems, like myopia, hyperopia, and astigmatism. However, with the right kind of treatment, all these conditions can be cured.
Structure of the Cornea
The human cornea consists of five layers. Now, let’s discuss about these layers in details.
- Corneal Epithelium (Maintains Healthy Eye)
It is a thin multicellular epithelial tissue layer of easily generated cells. The tears keep it moist. Any irregularity of this section might distort the air tear-film interface’s smoothness. Well, it is the most important element of refractive power and also reducing visual activity. It comprises of six layers that cast-off continuously on the exposed layer and keep on regenerating.
- Bowman’ Layer(Eye Protection)
This portion is a tough layer made of collagen, nidogen, laminin, perlecan to protect the corneal stroma and it is about 8-14 micrometers thick. It can be portrayed as a cellular, a condensed area of apical stroma and mainly comprised of woven collagen fibrils.
- Corneal Stroma(Clarity of Eye)
It is the broad transparent middle layer made up of collagen fibers with occasional shared interconnected keratocytes. The 90 pct of the corneal thickness is composed of the stroma. The stroma comprises roughly around 200 layers of type I collagen fibrils. The two statements that are stating the transparency of the cornea:-
- The lattice positioning of the collagen fibrils in the stroma.
- The spacing of the neighboring collagen fibrils must be less than 200 nm.
- Descemet’ Membrane(Protection From Infection)
It is a thin cellular layer that acts as the reshaped basement membrane of the corneal endothelium. This layer consists of collagen type IV fibrils. It is around 5-20 microns thick.
- Corneal Endothelium(Nourishes Eye Fluid)
It’s a low cuboidal monolayer made up of mitochondria-rich cells. The cells are responsible for controlling fluid as well as solute transport from corneal and aqueous stromal compartments. These cells do not regenerate and help to reduce the over cell density of the endothelium. The iris pigments also get deposited here. If the endothelium is not being able to maintain the proper fluid balance then it will cause stromal swelling and subsequent loss of transparency.
Conditions That Affect The Cornea
Small scratches in the cornea will heal on their own. Deeper scratches can cause corneal scarring and even loss of vision.
It is an inflammation and swelling of the cornea. This happens due to infections on the contact lenses.
- Dry Eye
It happens when it does not make enough tears to wet. Well!! AT times it can because of vision problems.
- Corneal Dystrophies
It creates cloudy vision when matter builds on the cornea.
Diseases That Affect Cornea
- Ocular Herpes
- Stevens-Jonson syndrome
- Iridocorneal endothelial syndrome
Several Treatments for Corneal Conditions
- Laser Treatment
The laser treatment called phototherapeutic keratectomy (PTK) is done to reshape the cornea, make a clear vision, and remove scar tissue.
- Corneal Transplant Surgery
The doctor removes the damaged part and replaces it with the healthy corneal tissue, which is denoted by a donor.
- Artificial Cornea
It is an alternative to corneal transplant, where the doctor replaces a damaged cornea with an artificial one.

Patients suffering from certain conditions that might lead to corneal blindness should go for corneal transplantation. The conditions are mentioned below:
- Scarring of the cornea from past injuries, infection, or surgeries.
- Keratoconus causes thinning of the cornea.
- LASIK complications
- Swelling in cornea because of hereditary weakness
Corneal transplantation, also known as corneal grafting is a procedure to rectify the blindness that is caused by corneal disease. The operation requires the removal of the damaged cornea and replacing it with healthy corneal tissue. The corneal tissue is either entirely implanted or partially implanted. The corneal tissue is taken from a deceased person with no eye disease.
The vision starts to improve with time, provided the surgery becomes successful and the tissue or graft is well-accepted by the eye of the recipient. However, the healing takes time and the patient might be advised glasses.
