Astigmatism can be corrected using glasses, certain types of contact lenses or surgery. The glasses are a good, reliable option. Patients who prefer to wear contact lenses improve more with hard lenses, soft lenses but can be used but are not as effective. Surgery may be an option, especially for those with dry eyes or other diseases that prevent them from using corrective lenses. The most common type of surgery used to correct astigmatism is LASIK (laser in situ keratomileusis).
In this surgery, it makes a small cut in the eye’s surface to create a small flap of tissue, which then rises. Then using a cold laser beam to correct the curvature exists in irregular astigmatism. Generally, recovery is rapid and painless. Read the rest of this entry »
The most common symptom of astigmatism is blurred vision. Some people describe it as double vision but one eye. Some people with astigmatism develop eyestrain, strabismus (crossed eye) and headaches for their efforts to focus on objects that are near or far. People are born with astigmatism, but may not be noticed until the child begins to attend school or learn to read.
Both the ophthalmologist and the optometrist can diagnose astigmatism using a standard eye exam. Read the rest of this entry »
Astigmatism means the cornea is irregularly shaped. This causes vision problems. The cornea is the transparent layer that covers the lens and iris. The cornea protects these structures and helps to transmit the light entering the eye. Usually the cornea is spherical, although people with astigmatism can be oval or football. This causes light to scatter instead of focusing on a single point as it passes through the cornea and result in blurring of vision.
