Cataract - Treatment of Cataract

From time to time many people claim to reverse halt or treat cataract using medication and eyedrops which is a fallacy.

The only treatment for cataract is to remove it.

In the fifties and sixties intracapsular surgery was performed where the whole lens in its bag was removed after the eye was cut open by 180 degrees i.e. half the eye was cut open with a blade. The big disadvantage was that since there was no lens the vision was poor and very thick +10 number spectacles had to be worn continuously. Patients lay still for upto 2 months at a time till the wound healed. Naturally in the summer this was intolerable as bathing was banned for more than a month. Even today people refrain from cataract surgery in the summer as a hangover of the old days!

The 1970’s saw the advent of implantable lenses. The eye was still cut open but by about 120 degrees now and fewer stitches were put. The risk of bleeding and poor vision and more complications were still there.

Lenses in the eye are not a new invention. During world war two a young English Ophthalmologist (Sir) Harold Ridley noticed that small fragments of the cockpit canopy of the spitfire fighter in the eyes of pilots did not cause any reaction. Till 15 years ago all lenses were made of this Perspex material!

Modern cataract surgery as we know it today uses different techniques to remove cataract out through between 0.7 mm to 3 mm. Laser energy or ultrasound energy or warn water jets are used to break up the cataract which is sucked out. The most modern of these techniques, about 2006 onwards uses warm water jets called AQUALASE to simply remove the lens gently by dissolving it. Also we can now go in through just 0.7 millimeter (as big as the tip of a ballpoint) and break up the cataract with ultrasound energy where the tip vibrates 40,000 times a second called 700 micronphaco.

Earlier energy was applied to the cataract in large “packets”.New for 2014 is “programmable Emmision” where size and duration of the packets are modulated by a computer.

This means that as compared to just 5 years ago less than 10 percent of the energy is used to remove the same grade of cataract.There fore the eye recovers faster.

The lenses which are implanted in the eye today are very soft and are rolled up and injected into the eye through as small as 1 mm where they will open up. Naturally since the opening is so small it seals nearly instantly and the patient does not need sutures or a bandage.he can even resume work the next day with just protective glasses. Since the opening is so minute. The risk of bleeding is virtually absent and diabetics do not need time to heal etc as the amount of actual healing needed is miniscule.

These lens materials today are biocompatibleacrylic and should comfortably outlast even a young patients lifespan as they are non reactive with the body.

Lenses can be single focal i.e. the person does not need spectacles for distance or multifocal which means he or she is spectacle independent after surgery. However multifocal lenses are a compromise and the person may see rings of light at night and may still need a small number to read. Even so they have greatly gained in popularity despite their increased cost. For eg. theLisaTri multifocal lens retails for upwards of 1500 dollars for a single lens!

In short, Cataract Surgery is no more the major adventure it was just 20 years ago and modern technology along with new techniques allow for a short hospital visit and nearly instant recovery

Most Common Surgery Now Safer
New Cataract Surgical Device Designed to Reduce Complicationsinfiniti2-224x3641

More than 2.5 million people undergo cataract removal surgery in the US each year, and now researchers at Alcon Laboratories have recently devised a new technique that could make the most commonly performed surgery in the US a little safer.

There’s a new advancement in lens removal technology that may reduce the risk of thermal burns and other potential complications called the AquaLase® Liquefaction Device.

Instead of using a metal probe, a doctor can now dissolve a patient’s clouded lens with pulses of warm naturally balanced solution to ‘wash away’ the lens layer-by-layer. First Alcon Infiniti Cataract Surgical System sold in India, Installed at our Institute.

AquaLase® Liquefaction Device is part of the Infiniti™ Vision System, the world’s first tri-modal cataract removal surgical instrument.

Alcon’s entirely new AquaLase® liquefaction device that generate fluid ultra micro-pulses in milliseconds, gently and with unprecedented, virtual, total safety safely break up and remove the natural lens material, dissolving the cataract.

Increased flexibility and greater options provide surgeons with more control over the lens-removal procedure, which potentially offers the reduced risk of complications. It also represents the first departure from ultrasound phacoemulsification, which has been the industry standard for almost 25 years.
