What is Cataract?

Cataract is an opacity in the lens of the eye. The normal lens is transparent and allows light to reach the retina. When it becomes opaque (Cataract) light does not reach the retina and the patient is unable to see clearly.

Why does Cataract form?

Cataract is the most common cause of blindness in our country. The causes o formation of cataract are not fully known.

1.It is an aging problem.

2.Ultraviolet light exposure.

3.Deficiency of protein and vitamins.

Apart from cataract in old age (senile cataract) cataract can also occur in children (congenital cataract) or Adolescents (Developmental cataract). Injuries can produce cataracts in all age groups. Patients with Diabetes mellitus develop cataracts earlier than a normal person.


1.Blurring of image in bright light.

2.Double images.

3.Image distortion.

4.Unequal vision in eyes.

Treatment of Cataract

Till today there is no drug, which has been proved to cure cataract. The only treatment available is surgery i.e., removal of cataract.

When does cataract require removal?

Apart from the mature cataracts, even immature cataracts need to be removed if it hampers with the patients visual requirements. There is no necessity to wait for the cataract to ripen as in earlier times.

At Rajan Eye Care Hospital we are performing the latest techniques for cataract removal. We remove the cataract through a small incision by an ultrasonic aspiration technique called Phacoemulsification. Almost all the patients are implanted with intraocular lenses. The success rate after surgery is close to 99.5%.

Evolution of Cataract Surgery


Small incision cataract surgery

Continuting the trend of Smaller is Better, Minimally invasive surgeries like cardiac and Gastro-enterology surgery, the cataract surgery has also moved from large incision (12mm) to smaller incision (6mm) to even smaller incision (3mm). And then to micro incision.

The present options in phaco surgeries are:

1.Standard Phaco

First Generation Phaco surgery done using simpler machines, the incision size is 3.2 mm. This type of surgery was first conducted in late 70’s. The surgery was done using injection to give local anesthesia.

2.Cold Phoco

The second generation phaco surgery, the normal incision size is 2.8mm but it is much safer since the amount of heat being delivered to the eye gets reduced significantly thus reducing the trauma. The walk-in, walk-out surgery thus resulted without using injection and patch.

Now-Asia’s First Microincisional (Mini-Keyhole) Cataract Surgery

Bausch & Lomb introduces a revolutionary technology for doing. 1.6mm to 1.8mm Micro incision cataract surgery. The stellaris MICS platform enables surgeon to do a microincision (1.6 – 1.8mm) cataract surgery that is not possible with any other system.

The Stellaris MICS platform consists

STELLARIS, Vision Enhancement System that performs stellaris MICS.

Akreos AO MIL, the advanced optic lens that is capable of being inserted through sub 1.8mm incision

Stability over time

Quality of vision

Capsular transparency


The Stellaris MICS technology offers the following benefits

  1. Quicker Surgery (Sutureless)
  2. Faster Recovery (Most Comfortable)
  3. Minimal Post-Operative Restrictions
  4. Better Vision Quality (AO Technology)
  5. Astigmatism Neutral (Least Dependancy on Spectacles)
  6. All the surgeries are performed using disposable pack to ensure high safety standards.
