Abstract Details

Purpose:

To report the technique and the outcomes of surgery for posterior polar cataract utilizing the novel positive pressure float technique.

Setting:

Mehta International Eye Institute, India

Methods:

This prospective study included 56 eyes with posterior polar cataract without any co-morbidity. All eyes underwent pre-operative CCT (central corneal thickness). Performed by a single surgeon by a standardized technique. A 23 gauge pars plana infusion inserted prior commencement of surgery and connected by a “Y” tube to the line from fluid inflow leading into the phacoemulsifier. Thus, fluid simultaneously flows to both the posterior and the anterior segment stabilizing the face. Cases were evaluated at 4 weeks for CCT, AC reaction, IOL centration, presence of CME, UCVA and BCVA. OCT was done in all patients with PCR or CME.

Results:

This prospective study included 56 eyes with posterior polar cataract without any co-morbidity. All eyes underwent pre-operative CCT (central corneal thickness).

Cases were evaluated at 4 weeks for CCT, AC reaction, IOL centration, presence of CME, UCVA and BCVA. OCT was done in all patients with PCR or CME.

Conclusions:

Posterior polar cataracts represent a large subset of non traumatic referrals in our centre. Using the balanced anterior / posterior segment fluid flow system we have had no breaks in the posterior polar cataracts .Understanding the fluidic dynamic principles involved in the technique, anticipating the possible problems and managing them adequately with a posterior segment fluidic balance helped us achieve satisfactory technical and visual outcomes.
