What is cataract?
If due to age or any other cause, there is opacity or clouding in the lens, vision gets affected. This clouding of the natural lens inside the eye is called cataract. Cataracts typically, in adults, causes gradual diminished vision and progress slowly.

What are the common causes of cataract?

  • The most common cause of cataracts is really just aging.
  • Systemic diseases can be associated with cataracts, such as diabetes
  • Drugs can cause cataracts, such as steroids
  • Any other disease in the eye can also lead to cataract,eg uveitis
  • Injury to eye
  • Children can be born with congenital cataract
If you have any of these symptoms, it is best to seek expert advice. One of the reasons to have an eye exam is not just to diagnose cataracts or no cataracts, but to make sure there isn't any other problem that's causing loss of vision. It could be glaucoma, diabetes in the eye, other serious problems that might be changing the vision, and that's important to determine. Is it cataract alone, or is they’re any other issue going on?

What is the treatment for cataract?
The only definitive treatment for cataract is surgery. THERE IS NO PROVEN EFFECTIVE MEDICAL TREATMENT FOR CATARACT WORLD OVER.

When do I get operated for cataract?
The timing for cataract surgery really depends almost always on the patient. When does your vision become a problem? When can you no longer drive, maybe no longer do the activities you like to do, see TV, read, do your crossword puzzle? when does the daytime glare bother you?When you can't get by, that's the time to do cataract surgery.

 What is the surgery for cataract?
It is a sophisticated procedure called phacoemulsification which over years has become one of the most successful and safe surgeries. The complete surgery is done through a very small self sealing incision. The cloudy lens is broken into small pieces and sucked out by an ultrasonic high speed vibrating handpiece.After all the cataract material is removed,the back capsule of the lens is left behind on which a clear foldable intraocular lens is implanted. Most of the times we do the surgery under topical anesthesia-only eye drops are used to make your eyes numb so that there is no pain felt.. As there is no injection near the eye involved, patient feels very comfortable and goes back without any pad and bandage.

What is the advantage of phacoemulsification with Foldable IOL?
The main advantages are early recovery and decreased occurrence of spectacle power (astigmatism/cylindrical error). Foldable IOL vis a vis Non Foldable are better as they go thru the same small incision. For non foldable lens ,one has to enlarge the size of incision.

How long is my stay in hospital?
It is a day care surgery where the patient comes in goes home the same day in couple of hour

What is the recovery time?
Our patients are allowed to resume their normal routine activity on the same day. There are no restrictions on diet, watching TV, reading etc. Initially you may have little hazy vision, mild redness or watering or foreign body sensation. You may notice that colors are different,blue or a red tinge.All this settles down in couple of days. It is advised to wear tinted glasses for outdoor activities to protect the eye from dust n sun for 1 or 2 weeks. Swimming and splashing of water in eyes is to be avoided for couple of weeks.
When does my vision restore fully?
Final glasses prescription is given one month after the surgery. You may or may not need any correction for distance but for reading, you would need glasses
Are there any risks and complications of surgery?
Like any surgery, there is a small potential of risk and complication, but with the newer machines n expertise, these are much less .Some of the complications can be serious, such as bleeding, infection, damage to the inside of the eye, the retina.  
Can the cataract come up again after surgery?
We have to leave behind the capsule of natural lens while operating, on which the clear artificial lens is placed. In few patients, over time this capsule gets cloudy. It’s called an after-cataract, the good news is, if you do get that opacification, it can be easily taken care of in few minutes as an OPD procedure by laser. A small opening is made in the capsule by laser, which helps to restore your vision back to normal.

Can both the eyes be operated together?
No never. Most surgeons will do one eye, make sure that eye is healed and doing well, and then operate the other eye after about 3 to 4 weeks.

What are the latest advancements in cataract surgery?
There are lot of advancements being made in cataract surgery both on machinery and intraocular lenses.

  • Cold phacoemulsification:
    The ultrasonic power and vibrating tip of phaco hand piece induces thermal change at incision and back of cornea. The newer generation machines have built in softwares  to create micropulses which allows more cooling time and hence less thermal damage to surrounding structures.
  • Microincision phacoemulsification:
    The instrumentation used are all micro-fine so that the incision for surgery is further reduced to 1mm.There is no surgically induced astigmatism and allows faster recovery.

IntraOcular Lens:
There is a whole lot of research and advances being made in the intraocular lenses in terms of the material being used, their optics, design etc. We now have implants that can block ultraviolet light, give better contrast sensitivity- sharpness in vision, are more biocompatible and decrease the rate of posterior capsule opacification.

  • Aspheric intraocular lens-spherical aberration free:
    The cornea has inherent positive aberrations. After implanting a traditional spherical intraocular lens, the implanted lens ‘s spherical aberrations can add up to it cause lower contrast sensitivity. The aspheric lens have negative or no spherical aberrations so that patient may have better sharpness in vision.
  • Ultraviolet protective intraocular lens:
    The material of these lens have chromophoric compound incorporated in them to absorb and filter out the ultraviolet light. Hence they protect the eyes from the harmful effect of ultraviolet light such as age related macular degeneration
  • Multifocal intraocular lens:
    These lens promise to give a person freedom from wearing glasses after cataract surgery. They are designed in such a way that their optics allows both distant and near vision, hence, reducing the dependence on glasses. These have to be chosen by the doctor for each patient on an individual basis as there is a selection criteria for opting them. Some patients may still require glasses for fine prints and some may have lower contrast and color saturation. Hence the decision of opting for multifocal has to be discussed for each patient with the surgeon.
Laser Cataract Surgery :
People have a myth that laser is being used in India to operate on cataract. The technique called phacoemulsification for cataract surgery uses the ultrasonic power to break cataract into small pieces. The quest for utilizing laser for cataract surgery had started two decades back but despite the excitement associated with using neodymium Yag or erbium Yag laser for cataract removal, there is still an on going research to refine the technique and laser system machines (Photon,Phacolase,Dodick etc) for cataract surgery.Highlight: No stitch, No injection, No pad and bandage in cataract surgery

Why choose us for your cataract surgery?
At our hospital, we use the latest technique and instrumentation for phacoemulsification. Adequate time and effort is given for detailed examination of every individual, ideal lens is chosen after exact calculation of lens power. The foldable intraocular lenses used are of premium quality. Most surgeries are done under topical anesthesia which gives the advantage of “No injection, No  pad and bandage” .Each surgery is done under the supervision of anaesthetist in an ultramodern aseptic operation theatre.
