Cataract Eye Treatment


What Happens In Cataracts

A cataract majorly refers to a cloudy area in the lens of your eye. As you get older, cataracts become very common! In the initial stages, it might be unclear that you have a cataract.But over time, cataracts lead to blurred or less colorful vision. You may have trouble reading or doing other everyday activities.

But, the good news for you is : surgery can help you get rid of cataracts. Cataract surgery is safe and corrects vision problems caused by cataracts.

Reason for Cataract

Causes Of Cataract

As such, the exact reason for Cataract is still unknown! But age factor is a big concern, though! As we grow older, the proteins that make up the eye's natural lens can clump together to form a cloudy layer on the lens making it harder to see.

The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. It also adjusts the eye's focus, letting us see things both up close and far away.

Water and protein make up most of the lens of the eye. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it.

No one knows for sure why the eye's lens changes as we age, forming cataracts. But some of the major causes could be

Types of Cataracts


Treatment Options

Microincision Phacoemulsification Cataract Surgery

A small incision is made on the side of the cornea, the clear, dome-shaped surface that covers the front of the eye. Your doctor inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the lens so that it can be removed by suction. This is called as Phacoemulsification.

At Sri Eye Care, we use a newer modification of this technique as Microincision Phaco Surgery [MICS], where the size of incision is only 2.2mmm. This has a dual advantage of faster healing time as well as better control of post-operative astigmatism. Once the lens material is removed from the eye, a foldable artificial lens is placed in the remaining capsular bag. The procedure is usually performed with the help of numbing drops, without the need of painful local anaesthetic injections.

Extracapsular Cataract Surgery

Extracapsular Cataract Surgery

Your doctor makes a longer self-sealing incision on the side of the cornea and removes the cloudy core of the lens in one piece. The rest of the lens is removed by suction. Prior to cataract surgery, antibiotic eye drops may be prescribed to prevent infection. This type of cataract surgery is most often done with local anaesthesia.

The latest modification of this technique is known small incision cataract surgery or SICS. This type of technique is less preferred due to the longer healing time as well as the unpredictable astigmatic control it offers.

Frequently Asked Questions

What is a Cataract? Cataract

A cataract is a cloudiness of the eye's natural lens, which lies between the front and back areas of the eye, directly behind the pupil.

Are cataracts found only in older people? Cataract

Most cataracts develop slowly over time and affect people over age 50. About half of the Indian population has a cataract by age 65, and nearly everyone over age 75 has at least a mild cataract in one or both eyes.

In rare cases, infants can have congenital cataracts. These usually are related to the mother having Rubella, Chickenpox, or another infectious disease or nutritional deficiency during pregnacy; but sometimes they are inherited

How is a cataract removed? Logo

A small port is made in the front surface of the eye. A circular hole is then cut in the front of the thin membrane (anterior capsule) that encloses the eye's natural lens. Typically the lens is then broken into smaller pieces with the Microphacoemulsification [MICS] system and is removed from the eye.

Once the entire lens is removed, it is replaced with a clear implant called an intraocular lens (IOL) to restore vision. With the latest technology, the eye heals quickly after surgery without stitches or bandages.

How is a cataract detected? Logo

The best way to detect a cataract is through an eye exam. It is important to attend regular eye examinations, as many eye conditions cannot be detected otherwise. If you are experiencing changes in your vision, it is best to see your eye doctor right away.

How fast does a cataract develop? Logo

It depends on the person. For most people, cataracts develop very slowly over a period of years. Cataracts in younger people tend to develop faster, as well as cataracts in those with diabetes. For the first couple years, the changes may not be apparent, only a slight decline in vision.

Will spectacles be needed after the surgery? Logo

The patients will often need after a cataract surgery to use spectacles for reading, writing and manipulating small objects. The surgery extracts the crystalline lens damaged by cataract but does not restore the accommodation (good vision far and near altogether) ability. At present however thanks to the developments in intraocular lenses there has been presented a possibility to reduce the spectacles dependence or even drop them at all.

The intricate design of a multifocal lens allows to simulate the natural crystalline lens operation. This sort of lens will have several “focuses” each providing proper vision at a given distance range, both far and near. According to clinical research data around 85% of patients having had a multifocal lens implanted do not use spectacles or contact lenses ever.

Has one to be admitted to a hospital? Logo

There is no need to stay overnight in the hospital. The surgery is performed as daycare procedure. It takes 10-12minutes per eye. The patient goes home the same day, after the final check by the doctor.

What are the other modalities to treat cataract? Logo

Although people with very early cataract can be managed easily with glasses, earliest possible cataract extraction is becoming more popular due to the increased safety and accuracy of the procedure. Also, since most cataract surgeries are machine based procedures, the softer the cataract is, the lesser energy is use to liquify the lens matter, and faster the healing time.

Will my cataract surgery be painful? Cataract surgery

Most cataract surgeries performed at Sri Eye Care are done under topical anaesthesia. In simple terms, it means that drops are used to numb the eyes completely. So, the patient does not even feel anything.

What are the precautions after my cataract surgery? How many days of rest would I need? Surgery

After the surgical procedure, the patient rests in our cataract lounge for 15-20 minutes and is explained about the necessary medications and precautions. Usually, bandages are not used after the procedure to aid in faster visual recovery. Instead protective goggles are given.

We advise all our patients who have undergone the cataract procedure

  • Right ArrowTo use the protective goggles on for a period of 4 days indoors
  • Right ArrowTo avoid splashing water on their face and avoid wetting their hair for a period of 1 week
  • Right ArrowTo avoid exposure to dust, fumes and steam for a period of 1 week
  • Right ArrowTo resume TV watching, reading and near work within 24 hours of the cataract surgery
  • Right ArrowOnly with mulifocal and trifocal lenses
  • Right ArrowAvoid swimming for a period of 6 weeks
Can cataract be prevented from occurring by putting some drops or having some tablets or capsules Logo

There is no drop or any tablet or capsule that can prevent cataract, yes a few drops ( Cinneria or drops containing Pottasium Iodide) claim to reduce cataract & prevent it from happening, they are not effective & most of the people who use it eventually develop cataract and have to undergo cataract surgery.
