What is a cataract?

Cataract is a condition in which clouding of the lens occurs, which results in diminished eye sight. In normal individuals light enters the eye through the lens, the amount of light entering the eye is controlled by ‘Pupil’. Eventually, light then falls on the retina which is rich with blood vessels and nerves that send visual signals to the brain.

A cloudy formation in the eye lens in is thus a very discomforting situation hugely impairing the vision.

Services offered

Following are the cataract removal services available at Sandhya Eye Hospitals

Phacoemulsification : Phacoemulsification is a surgical procedure in which cataract in the eye is emulsified with an ultrasound hand piece. This surgical method requires a very small incision and doesn’t require any stitches. After removal of the bits and pieces of cataract from the extant lens a new lens is then inserted into the eye. This procedure facilitates faster healing of the patient immensely and the patients can perform their normal work soon after the surgery.

Small Incision Cataract Surgery (SICS) : This is one of the fastest of cataract removal surgeries that can be undertaken at high volume and low cost. As the name suggests in this procedure cataract is removed manually after making a small incision in the eye. The small incision then heals quickly enabling patients to perform their daily chores.

Extracapsular Extraction : Extracapsular extraction is a surgical procedure in which the lens of the eye is removed through a large incision. Later an artificial Intra Ocular Lens (IOL) is implanted and the incision is then closed with stitches. Healing process after extracapsular extraction is longer and this procedure is performed only in cases where the cataract is advanced.

Choice of lenses while cataract surgery

The following types of lenses can be implanted after cataract surgeries through a 1.8 to 2.8 mm opening

Aberration-Free/Aspheric IOLs

This category of Intra-ocular lens provides good quality vision to the patient after implantation in terms of greater contrast sensitivity and quality night vision. Besides, these lenses also filter out harmful UV/Blue light which are harmful to the retina.

Toric IOLs

These lenses after implantation correct astigmatism thereby helping the patient to avoid glasses for normal vision.

Multifocal IOLs

These IOLs provide clear vision for all distances therefore patients who had multifocal IOL implants need not wear glasses. At times, patients may experience glare during nights with multifocal IOL implants but gradually the vision adapts to these lenses.

Accommodating IOLs

These IOLs have flexible hinges which help to change focus depending on the distance of the object, thus avoiding the necessity of glasses for the patients.
