Cylindrical power, also known as astigmatism, is a common eye condition in children caused by a misshapen cornea or lens. It can cause serious vision-related problems in both children and adults. However, children are at risk of improper development of vision. This may occur for several reasons, but with a proper understanding of what cylindrical power is and the ability to recognise the symptoms, it can be treated at an early stage.
In this blog, we will explain in detail what cylindrical power is, what are the factors that cause it, common symptoms that you should recognise, and more.
Cylindrical power of the eye, also known as astigmatism, is a refractive problem in the cornea. This is a very common vision-related condition that changes how the light passes through the eye. In this condition, the patient’s cornea is misshapen; it is often curved and cylindrical like a rugby ball, hence the name.
Due to this, light cannot pass through the retina as it usually would, leading to blurred vision. Patients suffering from cylindrical power of the eye often complain about difficulty in reading clearly as well as recognising things at a distance. There can be several causes of astigmatism; let’s unpack them.
As mentioned earlier in the blog, cylindrical eyesight is caused by the irregular shape of the cornea. Patients with cylindrical power vision have oblate cornea instead of the natural spherical shape. In most cases, this is a congenital condition, i.e., the irregular shape of the cornea is present during birth.
This is a genetic disorder that can be passed through genes. Some patients with a family history of astigmatism can develop the disorder later in life due to keratoconus and other disorders. Cylindrical eyesight can also develop due to injuries and certain diseases.
The symptoms of cylindrical power may vary depending on the severity of the condition. Here are some common symptoms that you should not ignore.
An eye chart is a common diagnostic tool used for various types of eye tests, including cylindrical power. In this test, you will be asked to read letters from a chart hung on a wall. This helps the doctors determine the acuity or sharpness of your vision at various distances.
A phoropter is an ophthalmic testing device used to measure the refractive errors in the eye. In this test, you are supposed to look through a binocular-like structure and see which letters you can see clearly. This helps the doctor find your refractive error and the spectacles power you need. Based on the test results, the doctor will prescribe you glasses for clearer vision.
An autorefractor is a computer-controlled machine used in eye exams to accurately measure refractive errors. This is one of the best methods for the diagnosis of cylindrical power and other refractive errors in Mumbai. The autorefractor measures the changes in eye movement and the retina once light enters the eye. The doctor also shows a picture that moves in and out of focus and measures the changes in the eye. The autorefractor takes several measurements to provide accurate results.
A keratometer is used to measure the curvature of the anterior surface of the cornea. It does so by projecting light at the cornea and measuring the size of an image reflected. The diagnostic procedure may also involve a corneal topography scan, which helps find imperfections and distortions on the corneal surface.
A healthy and balanced diet is of utmost importance for optimal eye health. Eat a balanced diet rich in vitamins, minerals, and antioxidants to improve cylindrical power. These nutrients are often found in leafy greens, fish, fruits, and nuts. Additionally, staying hydrated also helps you maintain optimal eye health.
Cylindrical power glasses are the most common treatment for astigmatism. Glasses specifically made for cylindrical eye shapes can help you see clearly by compensating for the uneven cornea. These glasses are specifically designed to reflect light to ensure it completely reaches the retina. In addition to astigmatism, eyeglasses can also be used to treat nearsightedness or farsightedness.
Similar to eyeglasses, contact lenses also help patients live a normal life without any invasive treatment. Your doctor prescribes contact lenses after a complete eye test. Corrective contact lenses are another variation of these lenses prescribed to patients to wear at night. These lenses help to even out the curvature of the eye.
Refractive eye surgery is a good option for people who wish to regain normal vision without relying on glasses or lenses. Refractive surgery uses a laser beam to reshape the cornea, correcting vision problems. There are several types of refractive surgeries available, such as LASIK and LASEK.
Yes, cylindrical power can be cured by means of laser eye surgery as mentioned above. However, it is to be noted that the cylindrical power of the eye does not go away naturally. Eyeglasses and lenses are some of the non-surgical options to keep astigmatism in check in daily life.
If astigmatism is affecting your daily life, seeking professional help is a must. Common symptoms like blurred vision and poor night vision can be dangerous. If you suspect astigmatism, contact a reputed eye hospital in Mumbai at the earliest.
Cylindrical power is a common eye condition in children and adults alike. It is caused by to oblate cornea instead of a normal spherical shape and is highly treatable with laser eye surgeries like LASEK and LASIK. If you notice symptoms like blurred or distorted vision, poor night vision, and headaches that accompany it, you must get your eyes diagnosed by professionals.
