With the conference at Bombay Ophthalmologist’s Association (BOA) being flooded with expertise. Live surgeries were a huge success and doctors across the country came up with new techniques to better the processes.
Dr Mahipal Sachdev, Padma Shri awardee, Chairman, Medical Director & Senior Consultant Ophthalmology, Formerly Associate Professor, Dr R P Centre All India Institute Of Medical Sciences, who conducted a microincision surgery said, “I did a microincision cataract surgery, where you can push in the lens and remove the cataract and push then lens through 2.2mm incision.”
Further, he emphasised that the machine used in the surgery was highly specialised and fast, “What I demonstrated separate from the other surgery, was the use of a machine signature pro, which goes up to high vacuum. The pull on the fragment of the cataract is very high. And you can go up to 6.50 vacuum and 60 flow rate. It’s a fast machine and whenever the machine is fast, it has to have a very high end technology. So this is called as fusion fluidics.”
In it there are microprocessors which are sensing the inner part of the eye, every 4 milliseconds. So 250 times a second, it is sensing the pressure at the vacuum within the eye. And the vacuum and the flow rate are done by pump and the amount of energy that we need is reduced.
“When you are doing this procedure, you have to break the cataract into small pieces, that is done by ultrasonic energy and then it is suck out. So, here, the sucking is so controlled that the amount of energy needed to break cataract is less and that is the advantage. Second advantage is, there are different types of pumps, the machines are either based on peristaltic pumps, or on a venturi system. So this machine allows you to switch from one pump to another,” added Dr Sachdev.
Normally, machines are either peristaltic or venturi. So this machine allows you to switch pumps on the basis of the stage of surgery where you are in. So if you are removing a cortex , that time a ventury pump is much more efficient.
“The third advantage is there is a casa software, in it whatever is being done on the machine, is transmitted on to your iPads. And you can observe various surgeons, and customised these settings of the machine for different surgeries.”
“So I showed a high vacuum, high flow, minimal power MICS surgery that is Microincision Cataract Surgery.”
The live surgery also witnessed the implantation of an extended range of vision lens, “I implanted a extended range of vision lens ERV. It is FDA approved. It gives a patient a good vision at all distances (near, distance and intermediate) without the need of post operative glasses. There is dysphotias. This means that there is some amount of glare, double vision, star bust effect, which normally people get when they are using bifocal Lens,” he explained.
But this symphony lens has reduced dysphotias to a very significant extent because of two to three proprietary technologies, one is echelette design. Second is back surface of the lens is achromatic. So achromatic reduces the glare and the hallos and the patient gets good contrast even in dim light conditions, he explained.
