Keratoconus is a common bilateral corneal condition, occurring in more than 1 in 1000 people. The condition typically starts in adolescence and early adulthood.
Usually one eye is involved more than the other. Infrequently it may occur only in one eye.Keratoconus is a disease with an uncertain cause, and its progression following diagnosis is unpredictable. It is more common in people with allergies or those who rub a_imagetheir eyes frequently. If afflicting both eyes, the deterioration in vision can affect the patient’s ability to drive a car or read normal print. Further progression of the disease may lead to a need for surgery.
Despite its uncertainties, keratoconus can be successfully managed with a variety of clinical and surgical techniques, and often with little or no impairment to the patient’s quality of life.
KERATOCONUS (FROM GREEK: KERATO- HORN, CORNEA; AND KONOS CONE)
The cornea is the clear window on the front of the eye. It is usually a regular spherical dome in shape. The substance of the cornea consists of hundreds of layers that are linked to each other by a substance called collagen. If these collagen cross-links between layers are lost due to keratoconus, there is a progressive corneal thinning and stretching which gradually progresses, often in both eyes.
Normal pressure within the eye causes the cornea to bulge forward into an irregular cone shape. When light enters the eye, it first passes through the cornea. If the cornea has turned conical, there is distortion of the image. The eye develops astigmatism (cylindrical errors) and myopia [shortsightedness] and the vision may become severely blurred.
A simulation of the multiple images seen by a person with keratoconus:
Reported risk factors for keratoconus include eye rubbing, a family history of keratoconus, genetic predisposition, certain systemic disorders such as Down’s syndrome, ocular allergy, connective tissue disease, and long-term rigid contact lens wear. It is usually an inherited corneal disorder, often in an autosomal dominant fashion. This means that approximately 50% of family members may end up with it. But it also can be random with no other family members affected. It affects men and women in equal proportions and is bilateral in 90% of patients.
At early stages, the symptoms of keratoconus may be no different from just having the need for spectacle correction. As the disease progresses, the vision deteriorates. Visual acuity becomes impaired at all distances, and night vision is sometimes quite poor. Some individuals have vision in one eye that is markedly worse than that in the other eye. Some develop photophobia (sensitivity to bright light), eye strain from squinting in order to read, or itching in the eye. There is usually little or no sensation of pain. Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light.
Nitial management is tried with rigid contact lenses by our contact lens specialist. In very early stages of keratoconus, spectacles can suffice to correct minor astigmatism. As the treatmentcondition progresses, spectacles may no longer provide the patient with a satisfactory degree of visual acuity, and most doctors will move to managing the condition with contact lenses.
Rigid gas permeable contact lenses for keratoconus improve vision by means of tear fluid filling the gap between the irregular corneal surface and the smooth regular inner surface of the contact lens, thereby creating the effect of a smoother cornea.
Very few potential risks associated with this treatment have been reported so far. The Ultraviolet light dose used is designed to prevent damage to the cells that line the back of the cornea or the other structures within the eye.
No lens opacities (cataracts) have been attributed to this treatment in European trials.
The treatment involves the outer layer (epithelium) of the cornea.
There is therefore discomfort and a short-term haze.
For the first week following surgery you should protect the eye from injury. Do not rub or put pressure on the eye.
Take small pieces of cotton wool and place them in a bowl containing water. Boil for 15 minutes and keep the bowl covered. Wash your hands with soap. Take a small piece of the sterilized cotton wool from the bowl. Squeeze out the excess water. Clean the discharge around the upper and lower lids without applying pressure on the eye. This is generally needed in the morning as long as the ointment is being used at bed time. Fresh cotton is to be boiled twice a day if needed.
Never use a pin/needle to open the eye drop bottle. Screw on the cap tight to open it.
Retract the lower lid and instill one drop of the prescribed eye drop into the eye. Eye drops should be used as per the prescription. Only 1 drop at a time is enough.
Keep both eyes closed for atleast 10 minutes after
each eye drop. Put on dark glasses throughout the day for one week.
Wipe tears below the margin of the dark glasses. Do not touch the eye.
Do not place cotton wool between the glasses and the eye.
Do not sleep on the operated side for 2 days.
For the first 5 days from the time of operation, take a bath below the neck. Face and hair can be washed after 5 days. But avoid getting water inside the eye.
Avoid strenuous activities.
Do not lift any objects heavier than 10 kg for about 5 days after the surgery
You may start reading and watching TV after 2 days. Take rest frequently with both eyes closed.
Many people return to light work immediately after surgery, but please discuss your needs with your doctor during your post operative visit (next day).
Ask your doctor about any specific activities you may have in mind as in leaving town, driving, yoga, walks, gym etc.
