Q. What is Cataract?
A Cataract is a clouding that develops in the Natural lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. Our eye works like a camera where light from various objects passes through clear cornea and clear natural lens , so as lens start getting clouded and our vision starts getting blurred even we can see but quality of vision gets bad as lens get more clouded (mature) our vision deteriotes further.
Q. What are Types of Cataract?
Cataract can occur at any age. Cataract is usually aging process, senile cataract, occurring in the elderly, is characterized by an initial opacity in the lens, subsequent swelling of the lens and final shrinkage with complete loss of transparency. Moreover with time the cataract cortex liquefies to form a milky white fluid in , which can cause severe inflammation if the lens capsule ruptures and leaks. Untreated, the cataract can cause glaucoma. Very advanced cataracts with weak zonules are liable to dislocation anteriorly or posteriorly.
These days we see cataract in lot of Young patients.
Some children develop cataracts, called congenital cataracts, before or just after birth but these are usually dealt with in a different way to cataracts in adults.
Cataract can develop after injury to the eye called Traumatic cataract. They are managed with special care.
Cataract can develop due to some eye conditions like glaucoma, Uvetis, certain medicines like steroids and certain diseases like Diabetes they are called Secondary cataract.There primary cause has to be managed well.
Q. What are symptoms of cataract?
Some common symtoms are- Blurry vision, Poor colour perception, Glare , poor night vision, double vision or multiple images and frequent changes in glasses number , sometime pain due to raised eye pressure.
Early in the development of cataract distance vision decreses and changes in lens causes temperory improvement in near vision, which gives false impression to the patient that his near vision is increasing, and the gradual yellowing and opacification of the lens may reduce the perception of blue colours. Cataracts typically progress slowly to cause vision loss and are potentially blinding if untreated. The condition usually affects both eyes, but almost always one eye is affected earlier than the other.
Q. What do do next?
Folowing examinations are done:
- Vision test
- Tonometry ( Checking eye pressure)
- Dilated eye (retinal) examination
- B-scan ( If required)
- A-scan ( to check the power of Intraocular Lens to be implanted)
Treatment ( Surgery )
Surgery is the only treatment, there is no other treatment , surgery is done by three methods:
1. Old Extracapsular surgery
Where a large incision( 6 to 8 mm) is made to remove the cataract and large non Foldable IOL( intraocular Implant )Is put in the eye. Sutures are taken, this take long time to heal and large incssion causes more glasses number.All modern eye hospital don’t do this surgery anymore. Here injection is given to numb your eyes.
2. Modern PHACOEMULSIFICATION eye surgery
Where surgery is done through very tiny incision ( 2.8 mm) on the side of your cornea and a tiny probe is inserted in your eye and it breaks and softens the cataract by ultrasound waves and remove the cataract by suction. Thenlatest foldable IOL( Intraocular Implant ) is injected through this small incision. The whole surgery finishes fast and no suture is required. Recovery is fast.
3. Latest MICS ( Microincision cataract surgery)
With latest technology now we are doing cataract surgery through even very small ( 2.2 mm) incision and there are latest IOL( Intraocular Implants ) which go through this tiny incision.Hence recovery is very fast.
In modern day surgery we don’t use any injections. Surgery are done under eye drops and no eye bandage is put after surgery.
Risk & Complications
With advanced technology and good surgery , risk and complications are very less.
Which lens to chose? IOL( Intraocular Implants )
IOLs( Intraocular Implants ) are commonly called lenses. They are of two types:
1. Old type Non foldable IOL which are of rigid material – goes through large incision, not used in modern day surgery
2. Latest FOLDABLE IOLs/ lenses- Soft Acrylic material goes through small incision. they are of two types : Monofocal & Multifocal
Monofocal Foldable lenses: where your distance vision is corrected but you need to wear glasses for near vision . Among monofocal ASPHERIC lenses gives you much sharper vision.Followin figure shows few monofocal lenses
Special Toric lenses can correct your high cylindrical number.
Multifocal / Presbyopic Lenses are latest premium lenses which decreases your dependency on near vision.
Lenses are of Hydrophilic material or Hydrophobic material. Hydrophobic lenses causes less posterior capsule opacification.
Q. What happens on the day of surgery?
Your total stay at our eye centre is two hours. It is fully Aircontioned with very comfortable stay.Our staff takes good care of you. Post operative instructions are told to you in detail.
Q. Will I need any procedure after cataract surgery in future?
Months to years after cataract surgery your eye tissue which supports lens may become cloudy( posterior capsular opacification) and blurr your vision. Whenever this happens it can be treated by painless small opd procedure called YAG Laser capsulotomy.This happens less in Hydrophobic lenses.
