Astigmatism and More about it

An abnormally shaped cornea or lens is the root cause of astigmatism. Being astigmatic is extremely typical. The reason why each person’s cornea and lens are unique is unknown to medical professionals. However, they are aware that having astigmatism is a hereditary condition (passed down from parents).

Astigmatism can also be brought on by: Eye condition. Eye damage or after surgery. It is a fallacy that reading in dim light or watching television while seated closely to a screen creates astigmatism or aggravates it. The cornea and lens on the front of the eye are typically perfectly round. This aids in finely focusing light rays onto the retina to improve vision.

Some signs of astigmatism include: Eyesight that is hazy or distorted in certain places. Eyestrain. Headaches. Trying to see properly while squinting. Unpleasant vision. Astigmatism is not usually indicated by these symptoms. For a thorough eye exam to determine the cause of your symptoms, consult an ophthalmologist.

Children might not be aware that their vision is fuzzy. And they won’t likely voice an issue with distorted or blurry eyesight. However, if untreated, astigmatism can: Influence a child’s performance in sports and at school. Vision loss and amblyopia (lazy eye). This is why early childhood eye exams conducted by a pediatrician, family physician, or other eye care specialist are crucial. To receive the best care if astigmatism or another eye condition is discovered, consult an ophthalmologist.

Astigmatism can be identified by ophthalmologists during a thorough eye examination. Testing might involve: Eye diagram. On an eye chart, you will be required to read the letters. This evaluates your ability to see clearly at different distances, or visual acuity.

· Phoropter

You inform your doctor which letter you can see better by peering through a huge, binocular-like gadget. Your doctor formulates a prescription for you that will give you the best eyesight possible based on the information you submit.

· Autorefractor

Additionally, this tool aids in determining your astigmatism or other refractive defect. It operates by projecting a light into the eye and seeing how the light changes as it reflects off the retina. Your cornea’s curvature is measured by a keratometer.

Contact lenses for astigmatism or spectacles. To improve vision, they function by refractively concentrating light on the retina at the rear of your eye. RGP and toric soft lenses are the two primary astigmatism contact lens kinds (rigid gas permeable). RPG lenses might perform better for astigmatism that is more severe.

· Cataract Surgery

A laser reshapes the cornea during LASIK and other operations to modify how light passes through it.

There is no one optimal approach to correct astigmatism; the greatest correction is the one that works for your lifestyle and vision demands. Following your examination, you and your ophthalmologist can go over your options in in detail.
