Abstract Details

Purpose:

1. To use 3 D high resolution OCT built in the Catalys Femtosecond LASER system to detect pre-existing posterior capsular defect in posterior polar cataracts. 2. To increase intra operative safety during posterior polar cataract surgery.

Setting:

An observational study conducted on patients having posterior polar cataract, and opting for Femto LASER assisted cataract surgery, conducted in the operation theatre of our eye hospital.

Methods:

An observational study was conducted on 15 eyes of posterior polar cataract undergoing femtolaser assisted cataract surgery. Real time OCT guided imaging of CATALYS femto-laser system provides three-dimensional high-resolution reconstruction of the anterior segment structures showing integrity of the posterior capsule. In any case that showed a discontinuity of the posterior capsule, the posterior offset was increased to create an epinuclear cushion, thereby providing an additional safety zone.

Results:

Out of the 15 eyes that were observed, posterior defect was observed in 6 eyes (40%) on OCT imaging and found in 4 cases (26.6%) intraoperatively. All the cases were managed successfully with or without the use of anterior vitrectomy.

Conclusions:

Intraoperative 3 D high resolution OCT is an effective tool to diagnose pre-existing Posterior capsular defect in cases of posterior polar cataract, and hence take measures to reduce the risk of complications during surgery.
