About Cataract:

In a healthy eye, light enters the eye and passes through a clear lens focussing onto the retina at the back of the eye. The different parts of the retina collect this light and send a message to your brain, enabling you to see. In cataract, the lens becomes cloudy and blocks light from passing through. This causes blurred vision, colors might be muted, and you may experience difficulty in reading signs while driving at night..

Key Points to Remember:

• A cataract is not a growth or a film over the eye, but it occurs when the natural lens inside your eyes gets cloudy. It is not contagious.

• It is very common in older adults.

• The symptoms of cataracts are progressive and cannot be corrected with glasses or contacts

• When symptoms become bothersome or limit your daily activities, it’s time to consider treatment.

• Surgery is the only effective cure and is very safe.

 Causes & Risk Factors:

Cataracts in eyes are caused by changes in the proteins of the natural lens.

Conditions that can increase risk of cataract include:

• The most common cause of cataract is degenerative changes due to Increased Age

• Eye diseases like glaucoma, diabetes, infections and inflammation inside the eye etc.

• Prolonged Use of steroid drugs or certain other medication.

• Eye injuries

• Direct exposure to sunlight While people above the age of 45 are at a greater risk, cataract can sometimes occur in children. Both adult and childhood cataracts can be treated.

Symptoms If you have cataract, you may experience the following symptoms

• Cloudy pupil

• Colors of objects may appear faded

• Poor eyesight at night

• Difficulty in driving at night, especially because of the glare of lights

• Difficulty in reading in dim light

• Blurry vision or Coloured haloes

• You may see multiple images or double images (double vision)
How Cataract can be treated?

Cataracts are treated through a safe, effective surgery. Your doctor will remove your cloudy opaque lens and replace it with an artificial lens also called as “Intraocular Lens”, or an IOL. Since light can pass through this new lens, clear vision is restored. Unlike contact lenses, the IOL stays in your eye forever.

There are many types of IOLs.

The lens options include Monofocal lenses – corrects only distance vision, and Multifocal lens – corrects distance, intermediate and near vision. In cases of Astigmatism, customized “toric monofocal lenses” or “toric multifocal lenses” can be used.Your new lens should be able to restore vision to nearly what it was earlier, though you may need to wear glasses for reading or driving. Doctors and counsellors can help you choose the best lens for you.In adults, surgery is done under local anaesthesia. You will be awake, but you will not feel any pain.

Drishti Eye Hospitals offers various advanced surgical techniques to treat cataract. Based on the type of cataract you have, your health condition and your lifestyle, the Ophthalmologist will recommend the most suitable and safest option for you. The commonly used surgical techniques are:

Small Incision Cataract Surgery (SICS):

This is also a new technique where the cataract is removed manually through a slightly larger incision. This technique is used if your cataract is excessively hard, making phacoemulsification difficult.

Phacoemulsification (PHACO):

• This is the most commonly performed technique currently.

• In this method a tiny instrument is inserted through a very small incision.

• Ultrasound vibrations break the cataract into tiny pieces.

• These pieces are gently suctioned out.

FEMTO Laser Cataract Surgery

:The Femto-second laser is the latest breakthrough in advanced cataract surgery, resulting in higher precision and safety of crucial steps of the surgery. The laser can help in• Creation of surgical incisions• Perfect Circular opening on the lens surface (capsulotomy)• Fragmentation of the natural human cataractous lens
The additional advantage of this laser is that it helps in the correction of pre-existing corneal astigmatism (cylindrical power).

Advantages to PHACO/FEMTO:

• Faster healing because the incision is so small• Less likely to need stitches or sutures• Fewer follow-up visits• Stable vision within 1 month of surgery• Patients can read or watch TV after 1 week

Risks and Associated Complications

Complications are very rare and most can be treated. They usually occur when a patient has another eye disease that interferes with vision. If you have another eye condition, your consulting doctor may want to treat it before the cataract surgery.

Risks include:

• Inflammation

• Infection

• Bleeding

• Swelling

• Secondary cataract

• Vision loss

Preparing for Routine Cataract Surgery at Drishti:

You will likely need to take eye drops on the day before surgery, the day of surgery, and just after surgery. An eye doctor or counsellor will provide you with specific instructions as to when to apply the drops. Please inform the doctor if you are allergic to any medications.Do not use any other medicines on your eyes. Follow the doctor or counsellor’s instructions carefully. For quick healing without any complications, you must take your medicines as advised.


After the surgery, your vision should slowly get better. At first, your vision may be blurred. Your eyes may be itchy, watery, or slightly red for a few days. This is a normal part of healing. With proper care, your eyes should heal completely within 8 weeks.

Once you return home, you will need to take the following precautions:

• Remove the eye bandage and wear dark glasses

• Wash hands with soap before applying eye drops

• Clean the eyes once a day with a sterile cotton ball. To sterilize the cotton, dip it in boiling water and wait until it cools to room temperature.

• Wear dark glasses when traveling

• Follow the medication chart closely

For the first month, you will also need to:

• Avoid sunlight, smoke, and dust

• Avoid tobacco, smoking, and alcohol

• Patients with glaucoma will need to take their glaucoma medicines regularly

• Patients with diabetes or hypertension should monitor their blood sugar, blood pressure, and cholesterol levels

Precautions to be followed after cataract surgery

:• Avoid using the TV, computer, or smart phone. If you feel any eye pain, stop using electronics entirely.

• Do NOT remove the eye shield, bandage, or patch for 1 day.

• Do NOT go to sleep while wearing your glasses for 3 days.

• Do NOT sleep on the side of the face with the operated eye for 3 days.

• Do NOT shave for 1 week.• Avoid playing with children or pets for 1 week.

• Do NOT get water on face, shower, wash hair, or use facial cosmetics for 1 week.

• Do NOT wipe near the eye with anything other than a sterile tissue/cotton ball for 1 week.

• Do NOT go outside without wearing the dark sunglasses for 10 days.

• Avoid cooking foods that create smoke or steam for 10 days.

• Do NOT do anything that creates “pressure” on the body, such as lifting heavy weights or strenuous exercise for 15 days.

• Do NOT ride a two-wheeler without protective glasses for 15 days.

• Do NOT let dust or smoke get into the eye for 15 days.

• Resume all normal daily activities after 15 days.

If you have severe eye pain, redness, or vision loss, please visit an eye hospital immediately.

Which is the best surgical procedure?

The best surgical procedure is one that combines high precision and has the greatest safety margin. As of now Laser Cataract Surgery and selecting a package where all disposable instrumentation is used is probably the best.

Can cataract come back?

Once cataract is removed it cannot reoccur. However over a period of time, some patients may complain of cloudy vision. This condition is called secondary cataract and it can be treated by a simple laser procedure.

How successful is the cataract surgery?

The overall success rate of a cataract surgery is +98%. Continuous innovation in techniques and instruments has made the procedure simpler and safer than before.

Which is a good technique for cataract surgery?

Phacoemulsification is a good technique and has the following benefits – micro incision, stitch less, safe and fast visual recovery.
