What is Cataract?

The normal crystalline lens of the eye is clear and transparent. Whenever the lens develops cloudiness or opacity, it is called a ‘cataract’. This opacification obstructs light from being transmitted to the retina causing blurring of vision. This may be compared to a window that is frosted or fogged with steam.

 

What Causes a Cataract?

 

Most cataracts occur as a result of:

  •   Increasing age. The normal process of ageing may cause the lens to harden and turn cloudy.

 

Other less common causes of the development of cataract are:

  •   Injuries to the eye,
  •   Certain medication such as steroids
  •   Infections or inflammations within the eye,
  •   Radiation,
  •   Diabetes - can accelerate the process of cataract formation,
  •   Rarely some children are born with cataracts - as a congenital abnormality

 

MICS METHOD

  •   There may be hazy and blurred vision.
  •   Frequent changes in glass power.
  •   In nuclear cataract near vision becomes clear which is known as SECOND SIGHT FOR AGED
  •   Double vision and distortion of images may occur.
  •   The eye may be more sensitive to light glare, making night driving difficult.
  •   Things may seem brighter with one eye than the other.

      



                     



What is the treatment for Cataract?

  • Treatment for cataract is always by an operation to remove the opaque lens from the eye.
  • No medicine or drops can remove the cataract or opacity of the lens.

 

When should one be operated for Cataract?

When a cataract causes enough loss of sight to interfere with the patient’s routine lifestyle, it is time to remove it. Depending on individual needs, the patient and the ophthalmologist decide together when the cataract should be operated.

DO NOT WAIT FOR THE CATARACT TO GET MATURE as unnecessary delay can lead to avoidable complications and more difficult surgery. Cataract surgery can be undertaken successfully in any season. Summer season have absolutely no effect on the outcome of the cataract surgery. In short, whenever a patient is visually handicapped to carry on his / her daily activities, it is time to consider cataract surgery.

 

About Cataract Surgery

There are several surgical techniques for cataract removal. Cataract surgery through phacoemulsification is the most modern and advanced method for performing cataract surgery The operating surgeon is the best person to decide which technique is likely to yield the best result.

Phacoemulsification through a small incision is the most advanced method and allows safe and predictable surgery. A small instrument called the phaco probe is introduced within the eye. Ultrasonic vibrations generated within the probe break the cataract into multiple small pieces (emulsification), which are then removed using a suction device through the same probe. After removing the cataract, a foldable intraocular lens (IOL) is implanted in the eye through this small incision.

 

Advantages of Topical Phacoemulsification


Types of Intraocular Lenses

Mono-focal Non-Aspheric IOL: With this lens, the patient is required to wear spectacles selectively for distance and near vision to obtain clear vision as this IOL has only one point of focus. However, less contrast sensitivity and sharpness of vision compare to Aspheric IOL.

Mono-focal Aspheric IOL: With this lens, the patient is required to wear spectacles selectively for distance and near vision to obtain clear vision as this IOL has only one point of focus. However, the asphericity of the IOL leads to improved contrast sensitivity and sharpness of vision.

Toric IOL: It is meant for patients with existing corneal astigmatism (cylindrical numbers). It gives good quality distance vision with less dependence on glasses; patients will still require glasses for tasks such as reading or working at the computer.

Multifocal IOL: The lens is designed to provide both near and distance vision and thereby reduce spectacle dependency.

Multifocal Toric IOL: This lens has unique properties of multifocality as well as toxicity. It offers minimal dependence on glasses to patients who have pre-existing corneal astigmatism, thus allowing a full range of distance, intermediate, and near vision, Your doctor will suggest which IOL is suitable for your eye condition and your visual requirement.

 

How much visual recovery to expect?

Cataract surgery has a very high success rate, over 99% of cases are technically successful. It is, however, important to realize that factors other than technically successful cataract surgery play a very important role in the visual recovery after cataract surgery e.g. the condition of the retina, optic nerve, pre-existing disease, amblyopia (lazy eye), etc. Sometimes it may be difficult to diagnose the abnormality before the surgery because of the dense cataract.

With advances in science and technology, cataract surgery is now safer and more predictable than ever.
