Cataract Surgery (Phaco)


The human crystalline lens, which is clear and transparent is part of the focusing mechanism of the eye. With age,
the lens becomes cloudy and opaque, thereby hampering normal vision. Any opacity in the crystalline lens, which leads to decreased vision is cataract.
eye with cataract
The early cataractous lens bends light irregularly, so the images formed are blurred and unclear. When opaque,
the cataract may cut off light nearly in total, causing blindness (reversible).

What causes Cataract ?

Ageing is the most common cause. With age, proteins of the eye lens get altered and opacified leading to
cataract. Other causes include congenital and developmental anomalies, trauma, inflammation of the eye,
metabolic diseases like Diabetes, Hypothyroidism etc.,

What are the common symptoms of Cataract ?

Cataract makes simple tasks difficult and in some cases impossible to perform.

This happens on account of :

Cloudy or Blurred Vision

Changes in one's perception of colours

Sensitivity to bright lamps or sunlight

Poor night vision

Difficulty in driving especially at night

Frequent changes in eye glass prescription


What are the treatment options for Cataract ?

Surgery is the only course of treatment for cataract. There are two options available for cataract surgery :

Conventional Cataract surgery or Extra Capsular Cataract Extraction (SICS/ECCE)

Injections are given near the eye

Requires an incision of 7-8 mm

The cloudy eye lens is removed in one piece

A hard plastic lens is implanted

Multiple Stitches are required in ECCE

Final glass prescription could take even upto 10 weeks

Microincision Cataract Surgery (PHACOEMULSIFICATION)

Requires a very small incision of 1.5 - 2.8mm

Cataract Extraction with Phacoemulsification is followed by
foldable lens implantation

Walk-in Walk-out procedure

Stitchless, bloodless, painless surgery

Chances of infection are very low

  Minimum post surgery precautions

Quicker healing and recovery

When to go for Cataract removal ?

Cataract should be removed as soon as it begins to affect daily activities. With any of the above mentioned symptoms setting in, it is the right time to go for Cataract removal. 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 or rainy season have absolutely no effect on the outcome of the cataract surgery.


What is the recommended treatment for cataract ?

With phacoemulsification and implantation of foldable Intra Ocular Lens (IOL), treatment of cataract has
become very simple and sophisticated. The procedure is safe, accurate and leads to rapid recovery. Thus
phacoemulsification with foldable lens implant is the most recommended treatment for cataract.

What is phacoemulsification with foldable IOL ?

In phacoemulsification, ultrasound power is used to break the hard cataract into minute pieces, which are then
sucked out through a small 1.5-2.8mm incision. A foldable lens (IOL) of the required power is then implanted.
The soft construction allows the lens implant to be folded for insertion through a 1.5 to 2.8mm micro incision.
Once in place, the lens unfolds to its regular size of 6 mm.

What are the advantages of phacoemulsification with foldable IOL over conventional cataract surgery ?

It allows for a injectionless, stitchless, painless, no bandage surgery

Drops of local anaesthetic agent are used instead of an injection in the eye, thus leading to a walk-in
walk out procedure

Early visual rehabilitation for the patient

Minimum curvatural changes occur in the eye following surgery

Post surgery, the wound is very secure

Final glasses can be prescribed within two weeks


How soon after phaco surgery, will I be able to see ?

In some cases, the patient is able to see almost immediately following the surgery, although most
patients experience clear vision after one or two days

Will I need glasses after phaco surgery?

You may need to wear glasses only to fine -tune your vision. These spectacles have normal lenses unlike
thick lenses used in the past. If unifocal IOL is used, near vision glasses are almost always required.

Will activities have to be restricted after phaco surgery ?

Normal activities including walking, reading, writing, watching television etc. may be resumed soon after the
surgery. However, during the first week after the surgery, it is better to avoid strenuous activities & avoid
exposing the eye to water or dust.

Is there any diet restriction after phaco surgery?

There are absolutely no diet restrictions after phaco and you can continue with your normal diet. However, diet
regulation advised for other diseases like Diabetes, High blood pressure, etc must continue.

Can I have phaco surgery on one eye even if the other eye had been operated upon by the conventional
surgery ?

Yes, you may have micro incision Phaco surgery on your "Second Eye" provided there is no specific
contraindication for Phaco.

How long will the procedure take ?

With the advanced technique of the cataract surgery, removal of the cataract takes just about 2 minutes and the entire procedure would take about 5-8 minutes. All procedures are done with advanced operating microscopes form Carl Zeiss (Germany) & Signature

Benefits of Phaco surgery:

No hospitalization - Walk in, Walk out surgery.
Smaller incision- hence lesser complications related to the incision size.
Lesser induced astigmatism because of smaller incision.
No bandages minimal precautions.
No restriction on normal activities. Can join work from next morning.
Fast recovery of good vision in a matter of days.
Final spectacles at one or two weeks.
Early visual rehabilitation.
