Cataract

What is Cataract?
A cataract, mainly characterised by blurring vision, is the clouding of the lens in the eye leading to a decrease in vision. It appears as if the patient is seeing through a cloud/fog. As time passes the cloud/fog gradually gets denser and blocks the vision.

Some patients may also suffer from decreased colour contrasts, halos, etc. Subsequently, if untreated the vision is completely lost and the patient can see nothing but white light.

What causes cataract in the eye?
The lenses in our eyes are made up of protein and water. The protein is arranged in a precise way which keeps our lens clear and allows light to pass through it. As we age, the protein in the lens may cluster together and start to cloud small areas of the lens.
This is a cataract and over time, it may grow larger making it harder to see.
Symptoms:
Cataracts usually form quite slowly and you may not even realize until they start to block the light. Some of the symptoms are:
 Cloudy, blurry, foggy vision
 Changes in the way you see colour
 Inability to see in dim light
 Sensitivity to glare and light
 Increasing difficulty with vision at night
Treatment:
Unlike popular beliefs, glasses or medications will not cure cataracts. The only treatment is surgical removal of the affected lens. Since the eye cannot function without a lens, an artificial lens known as Intra Ocular Lens (IOL) is surgically implanted in the eye.

ECCE: Extra Capsular Cataract Extraction

This procedure involves cataract extraction along with the capsule that hold the lens. A non-foldable rigid lens is used for this procedure which requires a relatively larger incision, stitches and religious post-operative care.
This procedure is preferred only in special conditions like trauma or surgery failure. It is mostly avoided in modern days because of low levels of comfort, less than peaceful post-operative healing period and availability of easier and safer technology.
SICS: Small incision Cataract Surgery

This procedure involves cataract extraction with a smaller incision. A foldable lens is injected using an injector that allows the doctor to implant the IOL through a smaller incision. No stitches are required and post-operative period requires convenient, but important post-operative care. This procedure is known to have minimal complications.

PHACO: Phacoemulsification

Phaco is the most advanced procedure for cataract extraction. Unlike the previous techniques, this technique uses an Ultrasonic hand piece that modifies the crystalline lens and is then aspirated through a suction system.
Later, a foldable lens is implanted with an injector through minimal incision. Use of phaco machine reduces the surgery time drastically, enabling surgeons to make miracles in few hundred seconds.

MICS: Micro incision Cataract Surgery

MICS is technically an advanced lens injection system and does not differ much from phaco. The cataract extraction is like Phaco, using an ultrasonic probe to dim the lens and aspiration through suction system. This technique uses tightly foldable lens that is implanted through to narrow injector, requiring even smaller incision than SICS. Smaller incision facilitates faster recovery and fewer complications.

All these procedures differ minutely from one and other with the core function being removal of cataract lens and implanting the artificial lens. Do not worry about the cost as the cataract surgery is one of the most economic procedures in the surgical field.

Types of lens used -

Generally, the lenses used are Non – foldable or Rigid lens, Foldable, Hydrophobic, Hydrophilic, Acrylic, Multifocal, MICS.

Companies that are global giants in the field of ophthalmology research come up with lenses that contain more than one feature for example; “A foldable acrylic hydrophilic lOL” is one the most favourite IOLs for surgeons.

Each hybrid lens possesses a specifically well-developed feature of its own along with all the core characteristics that are required to restore the vision.

Your vision after the surgery

After a safe and successful surgery, you will experience a vision as if looking through a washed clean glass. However, after the surgery, if you opt for mono focal lens, glasses will be required for reading purpose.
