Abstract Details

Purpose:

We introduced three changes in the management protocol of PPC  for better control during surgery with resultant less chances of Posterior Capsular Rent (PCR)

Setting:

Eye7 group of eye hospitals, New Delhi, India

Methods:

1. Visco-dissection: Once the nucleus is removed after hydrodelineation, the epinuclear girdle sticking to the cortex is separated from the fornix of the bag using multi-point visco-dissection, extending the separation to 1.5 mm short of the PPC area. 2. Low Intra Ocular Pressure (IOP): The surgery is done at an IOP of 30 mmhg with Active Fluidics. 3. Anterior Chamber Maintainer (ACM): This is attached to a bottle height of 41 cm maintaining a stable chamber of 30 mmhg at all times, even while moving instruments in and out of the eye, and also during pauses in phaco irrigation.

Results:

40 cases of PPC were performed. PCR was encountered in only two cases (5%). Recent literature mentions a PCR rate of 7.1% to 16.4%. Bringing the incidence to 5 % is a step forward.

Conclusions:

Without a visco-dissection, removing the epinuclear girdle with an Irrigation Aspiration cannula poses a challenge, is time consuming and many a times the resultant manipulations results in a PCR. Maintaining the IOP at 30mmhg during the entire course of surgery reduces risk of PCR in an already compromised Posterior Capsule. Without an ACM, the chamber stability at 30mmhg cannot be secured. Without Active Fluidics, phaco cannot be done at an IOP of 30mmhg.
