Cataract Surgery

 What is Astigmatism?

Astigmatism is a vision defect where images are focused on different points near the retina. This can be due to irregular curvatures of the cornea and sometimes the lens as well.

An analogy to describe this condition is to liken the cornea to a rugby ball where one surface is more curved than the other. Light rays enter the eye and get focused on 2 different points, therefore causing blur and/or multiple visions. A cornea that is equally curved in all directions, like a soccer ball, will focus light on a single point, therefore giving clear vision.

An astigmatic eye presents blurry vision at distant and occasionally at near sight. In severe cases, the eye may see double or triple vision. Astigmatism can occur on its own, or together with myopia or hyperopia.

Common treatment options for astigmatism are wearing of glasses and contact lenses, undergoing LASIK or Implantable Contact Lens procedure, and undergoing cataract surgery (if the eye has also developed a cataract).

Cataract and Astigmatism Surgery

The technique for the cataract removal and astigmatism correction will vary from patient to patient, but usually, it is a simple procedure that may even eliminate the need for eyeglasses.

A cataract surgery is usually done as a day surgery which takes about 15-20 minutes depending on the type of cataract surgery. Astigmatism correction adds a few more minutes to that procedure. After about three to four hours in the surgery centre and some rest at home thereafter, most patients are able to resume normal activities the very next day. Patients are still encouraged to wait about a week before resuming normal activities. A few weeks after surgery, a follow-up appointment is necessary to evaluate new eyeglass prescription, if needed.
