BANGALORE, India — The latest tip designed for microphakonit offers better fluidics with a smaller incision, yet does not affect the overall technique, according to a surgeon speaking here.

“The 700-µm tip has made a world of difference because it has altered the necessary fluidics, which enables you to do phaco utilizing a fairly high level of vacuum,” Ocular Surgery News India Edition Editorial Board Member Keiki R. Mehta, MD, said during the All India Ophthalmological Society conference.

The tip, designed by OSN India Edition Editorial Board Member Amar Agarwal, MS, FRCS, FRCOphth, has been used frequently by top Indian cataract surgeons, Dr. Mehta said.

“Essentially, the technique remains identical,” he said. What changes is an increase in the amount of vacuum a surgeon can use, as compared to 900-µm phaco, allowing for up to 500 mm Hg of vacuum, he said.

Dr. Mehta added that the procedure is not slow, as some might expect, but that it proceeds at the conventional speed. In his own twist to the operation, Dr. Mehta said he uses a “wagging” technique to gather the cataract pieces.

“This is a system that works well and gives you excellent results,” he said. “Frankly, there is no reason for you not to do it.”
