A normal cornea, the outer covering of your eye, is dome-shaped. The corneal tissue may become weak and fail to hold its round shape. It causes the eye to bulge outward and take the form of a cone. This condition is called keratoconus. It occurs in one or both eyes.
Here are the signs that could suggest you have keratoconus:
Blurred or distorted vision.
Double vision when looking with one eye.
Sudden clouded vision.
A need for frequent alterations to your eyeglass prescription.
Increased light sensitivity.
Progressive myopia as the front of the eye expands.
Irregular astigmatism due to the changing shape of the cornea.
Bright lights seem to have halos around them.
Light streaks in your vision.
An optometrist will most likely start you on prescription glasses. If your case is only mild, wearing eyeglasses is enough to resolve the issue soon. If there’s no improvement, the eye doctor may further the treatment.
Here are some standard treatment methods:
There are now specially made soft contact lenses designed to correct keratoconus of the mild to moderate stage. These lenses are custom-made based on a person’s exact detailed measurements. They are also wider in diameter and more stable to wear than regular soft lenses.
Corneal crosslinking is a treatment procedure meant to toughen the cornea by adding to the anchors that link the collagen fibers together.
Corneal crosslinking is of two types. The first, epithelium-off crosslinking, refers to the removal of the outer layer of the cornea. Without the epithelium, riboflavin can enter the cornea freely. Riboflavin is a type B vitamin that activates in the presence of UV light.
The second method, epithelium-on crosslinking, is when the epithelium is left intact. It is also called transepithelial crosslinking. With this method, there’s less discomfort, lower risk of infection, and recovery is only in one day.
Corneal crosslinking promotes quick recovery. It also reduces the need for corneal transplants for keratoconus patients.
Gas permeable contact lenses are porous but also rigid. They press onto the cornea, changing its shape to improve your vision. The previously wavy cornea now takes a smooth uniform shape, making it easy to refract light.
Sclera lenses are porous large-diameter contact lenses. The lenses are wide enough to cover the sclera, the white part of the eye. Sclera lenses are also steadier than standard gas permeable contact lenses. They do not shift in your eye when you blink. Unlike regular gas permeable lenses that apply pressure to the cornea, these do not press on your eyeball. They are more comfortable to have on.
Intacs are FDA-approved arc-shaped corneal inserts that the doctor places in your eye through surgery. Intacs are designed to reshape the cornea to enhance your vision. They are suitable for when contact lenses and eyeglasses are no longer helpful. Another advantage is that these implants can be removed and replaced in a simple 10-minute surgery.
