There was a time when a cataract operation would take about 40 minutes or more to perform. Recovery would be slow and there were be several restrictions for the patient, such as no shower for a few days or stepping out in the open.
But technological changes have brought a big change in cataract surgeries. Dr Keiki Mehta, a leading eye surgeon and Surgical Chief and Medical Director of Mehta International Eye Institute (MIEI), Mumbai, refers to the new FemtoSecond laser device called Catalys, a bladeless, precision laser cataract system that he has introduced at his hospital.
"This is a completely automated system," remarks Mehta. "The big advantage is that it takes less than a minute for the operation. The patient lies down, the laser is turned on, and turns the cataract lens into fragments."
The entire procedure, including sucking out the fragmented parts and putting a new lens, is completed in less than 60 seconds. If the cataract is hard, it would take about 40 seconds, but if it is soft, the procedure can be done within 20 seconds. The patient can walk out of the clinic, go home, take a shower and return to work the next day. Mehta says it is an extremely reliable and risk-free system.
His institute has also deployed a new system for treating glaucoma. The system drains the fluid inside the eye. It also reduces the chances of damage to the eye in case of injury.
MIEI has also introduced the Tecnis Symfony Extended Range of Vision intraocular lens, which gives a full range of vision from near to far distance without any glare. The hybrid intraocular lens provides high quality vision in all lighting conditions.
"The results have been good and patients are very happy," says Mehta. "They have done away with the need for glasses forever. The person will never get cataract as the natural lens has been replaced."
Mehta says he is planning to set up a 10,000-square feet centre of excellence at Parel in central Mumbai to cater to the needs of patients from across the metropolis. The local civic body had imposed restrictions on starting new operation theatres in the city, but it has recently amended the rules allowing new facilities to come up.
