Keratoconus
queratococono is a disease that damages the internal structure of the cornea and produces alterations in the surface thereof, thereby taking an irregularly shaped cone that produces astigmatism and myopia that eventually contributes to the gradual loss of sight.
Causes
generally this begins at puberty, the cause is unknown although theories imply a hereditary risk factor, and the ongoing process is recorded to the third and fourth decade of life. Each case demonstrates specific characteristics of progression.
Symptoms
the loss of vision due to keratoconus generated greatly impact the quality of life of patients, limiting their normal activities such as driving or social interaction. In severe cases high levels of visual loss and distortion can prevent the development of every day of the most basic life activities.
Importantly, this condition is a dystrophy of the cornea and its treatment depends on the severity of the deformation and thinning of the skin.
Treatment
Among the treatment options include glasses, intracorneal implantation, and corneal transplant to the more severe cases.
Is currently carrying out the intracorneal ring implants which are positioned within the corneal thickness to change the curvature of the same, without altering the focus area. This technique is reversible if it does not have the expected results.
The studies seek to achieve a recovery technique to morphological original cornea, and visual rehabilitation, regardless of the degree of progress of this disease.
Corneal transplant
Corneal transplants are used when symptoms when patients have hypersensitivity to contact lenses and eye disorders you from driving, working or performing their daily work.
Corneal transplants have a success rate of 95% and the transplant success rate is higher, its techniques are improved day by day. During this transplant is sought to remove the central part of the patient’s cornea and replace it with healthy donor cornea.
Keratoconus is a progressive disease that must be controlled by an ophthalmologist, during frequent visits will be defined when the graduation is needed glasses or contact lenses. At first, the lenses can be used for myopia and astigmatism caused, but given the progress of the disease, contact lenses are rigid gas permeable only way to correct defects in the patient’s eyesight.
