To evaluate the efficacy of the viscocanalostomy/trabeculotomy with the Omni System for lowering intraocular pressure when performed at the time of cataract surgery.
This prospective study will comprise 50 eyes undergoing combined cataract surgery/Omni. The preoperative and postoperative IOP and number of ocular anti-hypertensive medications will be recorded. Eyes will be stratified according to their preoperative IOP (<20mmHg, 20-25mmHg, >25mmHg). Data will be analyzed for the 1M, 3M, 6M, 12M, 24M visits.
To date 18 eyes have been treated with a follow-up of 30 days or more. Mean pre-op IOP and number of medications is 18.7+/-4.1mmHg and 1.0+/-1.0 respectively. Mean postoperative IOP at 1M and 3M is 16.9+/-3.0mmHg and 14.8+/-2.2mmHg, respectively. All eyes were on the same or fewer number of IOP lowering medications at both postop intervals. Mean reduction in IOP is -1.8+/-3.6mmHg (-9 to +3mmHg) at 1M and -5.3+/-4.8mmHg (-11 to +1mmHg) at 3M.
The data suggests that combined viscocanalostomy/trabeculotomy performed at the time of cataract surgery has a tendency to significantly lower eye pressure (p=0.009 at 3M) and that the effect is stronger at 3M compared to 1M postoperatively. Longer follow-up on more eyes is needed to help assess the longer term efficacy of this new technique.
