DIAGNOSTICS Both Eye Corneal Topography:

Corneal topography, commonly referred to as photokeratoscopy or videokeratography, is a non-invasive medical imaging method used to map the anterior curvature of the cornea, the eye's outer structure.

A corneal topography examination creates comprehensive 3D maps of the cornea's shape and curve, making it possible to detect corneal illnesses and abnormal corneal conditions such edoema, scarring, abrasions, deformities, and irregular astigmatisms.

It's a noncontact examination that takes pictures of the eye's surface. Corneal topography isn't a common procedure. Rather, it is used to diagnose specific sorts of abnormalities, to assess the evolution of a disease, to fit certain types of contact lenses, and to schedule surgery.

Disease Overview:

When the cornea or lens is bent more sharply in one direction than the other, astigmatism results. If the curves of your cornea are misaligned, you have corneal astigmatism. If your lens has uneven curves, you have lenticular astigmatism. Blurred vision can be caused by any form of astigmatism.

Disease Signs and Symptoms:

• Vision that is hazy or distorted.
• Discomfort or strain in the eyes.
• Headaches.
• Night vision is difficult.
• Squinting.

Disease Causes:

Although the exact aetiology of astigmatism is unknown, heredity plays a significant role. It's common from birth, although it can also develop later in life. It can also happen as a result of an eye injury or following eye surgery. Astigmatism is common in those who are nearsighted or farsighted.

Disease Diagnosis:

An eye exam is used to determine if you have astigmatism. A comprehensive eye exam includes a battery of eye tests as well as a refraction, which evaluates how the eyes bend light. Your eye doctor may use a variety of tools, shine strong lights into your eyes, and ask you to look through a variety of lenses.

Disease Treatment:

Corrective lenses, either eyeglasses or contact lenses, are the most common therapy for astigmatism of all degrees. You may not require glasses if you have only a small astigmatism and no other vision problems (such as nearsightedness or farsightedness). Corrective lenses will most likely be required if you have moderate or high astigmatism.

Other alternatives for therapy include:

Orthokeratology entails wearing a set of custom-made contact lenses. Because the lenses are stiff, they gradually change the contour of your cornea.

LASIK surgery, or laser in-situ keratomileusis, can treat some forms of astigmatism. Consult your doctor to discover whether it's a good fit for you. A laser is used by the surgeon to remove a little bit of eye tissue and alter the cornea's shape.

PRK (photorefractive keratectomy) is an eye operation that removes tissue from the inner and outer layers of the cornea.
