Understanding What Is Cylindrical Power & How to Manage It
Meaning Of Cylindrical Power
Understanding What Cylindrical Power is: When the cornea, the frontmost layer of the eye, has an oblate rugby ball-like shape rather than a typical spherical one, it’s a sign of cylindrical power eye. Only in a specific orientation known as the axis does this shape cause the power to materialise. It indicates that the eyes are shaped so that a cylindrical quantity is required for clear vision, not that the eyes are weak or defective.
Patients with cylindrical eyesight of more than 3 diopters receive a topography test once a year to ensure they have not developed keratoconus, as very high cylindrical numbers (>3.00) may signal a disorder known as keratoconus.
There are many eye care centers, and the best ones with extraordinary expert teams are found in an eye hospital in Delhi at Suresh Garg Eye & Laser Hospital.
Now, let’s delve more into the in-depth study of cylindrical power, its diagnosis, and its management.
Causes of Astigmatism (cylindrical power)
The cornea’s aberrant shape results in astigmatism. Patients with cylindrical refractive error possess an oblate cornea rather than the typical spherical configuration. In most instances, it is a congenital disorder, meaning the cornea’s uneven shape is present at birth.
It is a hereditary genetic condition. People with a familial predisposition to astigmatism may subsequently develop the condition due to keratoconus and other illnesses. Cylindrical vision may also arise from traumas and specific disorders.

Symptoms of Astigmatism (Cylindrical Power)
The severity of the illness can affect the symptoms of cylindrical power, which can differ from person to person. Listed below are some symptoms that are rather prevalent and should not be ignored:
- Visual impairments such as blurred or distorted vision are brought on by an uneven dispersion of light on the retina, which is the source of these visual impairments.
- One of the first and most prevalent symptoms of astigmatism is the appearance of this symptom.
- You may experience strain and discomfort in your eyes when you are concentrating on surrounding items or reading small lettering.
- Astigmatism may lead you to squint to see clearly.
- If, in addition to having vision issues, you are also experiencing regular headaches, you should seek medical attention.
- Cylindrical eye disorders can make seeing well at night and in dark environments more difficult. This can lead to poor night vision.
Diagnosis of Astigmatism
- Eye Chart
An eye chart is a common diagnostic tool for various eye tests, including cylindrical power. In this test, you will be asked to read letters from a chart hung on a wall. It helps the doctors determine the acuity or sharpness of your vision at various distances.
- Phoropter
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. It helps the doctor find your refractive error and the spectacles power you need. The doctor will prescribe you glasses for clearer vision based on the test results.
- Autorefractor
An autorefractor is a computer-controlled machine used in eye exams to measure refractive errors accurately. It is one of Mumbai’s best methods for diagnosing cylindrical power and other refractive errors. 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.
- Keratometer
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.
Managing the Astigmatism
- Healthy Diet
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.
- Glasses
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 designed to reflect light to ensure it completely reaches the retina. In addition to astigmatism, eyeglasses can be used to treat nearsighted or farsightedness.
- Corrective Contact Lenses
Like eyeglasses, contact lenses also help patients live a normal life without 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
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. Several types of refractive surgeries are available, such as LASIK and LASEK.

FAQS About Cylindrical Power
1. Can Cylindrical Power be Cured?
As mentioned above, cylindrical power can be cured through laser eye surgery. 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.
2. When To Seek Professional Help?
If astigmatism affects your daily life, seeking professional help is necessary. 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.
3. Can astigmatism be cured through management?
Astigmatism cannot be cured, but effective management can control the condition, prevent further damage to the optic nerve, and preserve the remaining vision.
4. How often should I have my eyes checked if I have astigmatism?
Individuals with astigmatism should have regular eye exams, typically every 3 to 6 months, to monitor IOP and disease progression.
5. Can astigmatism medications have side effects?
Yes, astigmatism eye drops can have side effects like eye irritation and redness and systemic effects like heart rate changes. Discuss any concerns with your eye care professional.
