Astigmatism is a common and treatable eye condition that occurs when there are imperfections in the curvature of the eye that causes blurring and distortion in near and far away objects. It is correctable with spectacles, contact lenses and refractive eye surgery.
People of all ages can be affected by astigmatism and it is usually accompanied with long or short sightedness.
Astigmatism is caused by an irregular shaped eye. This affects the focus of light entering the eye which can distort the vision. The front of a ‘normal’ eye should typically be a symetrically curved shaped like a football but for those with the condition have more of a rugby ball shaped cornea, which have different curvatures in different directions. This changes the focus of light so it is not sharply focussed on the back of the eye.
The most typical symptom of astigmatism is blurry or distorted vision. Many people who have low levels of astigmatism are asymptomatic but a significant amount of astigmatism can cause:-

Astigmatism is mostly a hereditary condition. However other eye conditions can also cause the condition:
There are a number of options available to correct astigmatism. Spectacles, toric contact lenses and refractive eye surgery are all suitable methods to correct astigmatism. Laser eye surgery (LASIK or LASEK) are effective treatments. Cataract and Lens Replacement Surgery can also correct astigmatism. Refractive eye surgery will also correct any long or short sightedness, which may be present during the time of surgery.
Astigmatism surgery is done with a laser to change the shape of the cornea in two meridians and correct the irregularity. The laser surgery will also repair any long or short-sightedness, which may be present during the time of surgery. This is a speedy procedure and takes between 10-15 minutes to treat both eyes. The correction can be done on one eye immediately after the other.
It is never too early to correct astigmatism.
The surgery to correct astigmatism only takes between 10-15 minutes.
Astigmatism occurs when the eye looks like a rugby ball instead of a football. This irregular shape creates two focus points for light instead of one, thereby making the resulting image blurred.
Alongside the blurred vision, you may also experience squint, headache and fatigue as symptoms.
Surgeons use laser surgery to correct the shape of the eyeball so that light can rest directly on the retina for better vision. Wearing lenses (either from glasses or soft contact lenses) are also helpful in directing light to focus in the right place.
Studies show that the use of Rigid Gas Permeable (RGP) lenses is more effective than the soft contact lenses since it holds the shape of the eye in place. So, when the light comes in, it hits the spherical surface instead of the natural irregular one. The downside of this method of correction is that it may be uncomfortable for some patients.
Yes. Glasses with cylindrical lenses help in adjusting the way the eye focuses on light, thereby making the patient’s vision clearer. However this solution is not permanent and without the glasses, vision will revert back to blurry and distorted. Only refractive surgery is a solution to cure astigmatism permanently.

I had an absolutely wonderful experience doing Lasik at this clinic. Their entire staff was extremely professional and courteous throughout the entire process.
My surgeon was wonderful, made me feel entirely at ease before and during surgery. Highly recommended.
Laser eye surgery, now glasses free after 23 years! :)
I have always thought about laser, I have worn glasses for 23 years. I was very anxious, worried about the what ifs. I had an appointment with Dr Mani, he explained everything to me and I decided to go ahead with the surgery. It was so fast, Dr Mani did remind me to be patient and I think this is very important. I am now glasses free and hoping this will continue! After care was good, a week after surgery I was concerned and Dr Mani invited me down to check my eyes to be sure all was ok. Thank you

I had a great experience performing my laser eye surgery at Optimal Vision Clinic. All the staffs are very helpful, co-operative and supportive throughout the treatment process. On the first call, they explained the entire procedure in details and gave necessary instructions at every stage. My eye surgeon made me feel comfortable and relaxed before and during the procedure. Aftercare was done properly with a thorough check-up of my eyes. I would like to recommend this clinic to everyone!
Very happy and impressed with the highly professional care and service I’ve received at the Optimal Vision clinic. Dr Mani is so professional, and he explained everything about Laser surgery and answered all my questions. The surgery was quick and almost completely painless. My eyes have healed perfectly and quickly. I would highly recommend this clinic.
My husband had been experiencing discomfort in his left eye since July and was seen by various doctors/consultants even at the Queen Mary’s hospital but no abnormalities were found.
This week Dr. Mani discovered the fault which happened to be Retina detachment with three tears.
Dr. Mani’s preciseness and his perfectionist attitude to attention to details, detected the source of the main issue and saved my husband’s eye. We feel utterly grateful and can not recommend him enough for his excellence.
