We provide professional support in Cornea and its diseases.
The cornea is the transparent tissue in the front of the eye specialized to focus light.
It ensures that the light coming from the external environment is effectively focused on the retina.
The cornea has to be transparent for proper diffraction
of light. Therefore, it does not have blood vessels in its structure.
Since the cornea contains many nerve fibers in its
structure, it is very sensitive to external factors.
Like all living tissues, the cornea can be affected by all disease-causing causes.
The shape and transparency of the cornea may deteriorate
after congenital diseases. For example, the cornea may be congenitally
smaller than normal, a condition called microcornea.
Corneal infections are called keratitis.
Rheumatic diseases can damage the cornea. For
example, rheumatoid arthritis can be threatening by reducing moisture on the
The cornea can also be affected by allergic diseases. For example, vernal conjunctivitis, a type of allergic disease,
can cause damage to the cornea.
Keratoconus is a disease characterized by thinning of the cornea, conical tapering and
associated high astigmatism and visual impairment (see Keratoconus title).
Since the cornea is located in the outermost part of the eye, it is very vulnerable to injury.
After corneal trauma, the integrity of the eyeball may be
impaired, which is a condition that needs to be treated urgently.
The most important thing to do after the eye comes into
contact with acid or alkaline chemicals is to immediately wash the eye with
plenty of water and apply to a medical center equipped with the necessary
equipment. It may be necessary to wash the eye with liters of water, the
remaining chemical residues must be cleaned by turning the eyelids.
Corneal surgery is performed to change the integrity,
transparency or optical properties of the cornea.
Corneal transplant (keratoplasty) is a transplant surgery with a high chance
of success. Lamellar keratoplasty is a half-fold replacement of corneal
tissue. Penetrating keratoplasty is a full-thickness replacement of
Today, corneal surgery is commonly performed to correct myopia, hyperopia and astigmatism
Interventions to correct the refractive error are most often performed with the excimer laser (see Excimer Laser head).
