Abstract Details

Purpose:

To compare the panel data in three different settings during phocoemulsification.

Setting:

Tertiary care eye hospital of eastern India.

Methods:

In this prospective randomized control trial 285 consecutive cases of phacoemulsification where randomly distributed into three different intraoperative settings. Group 1: IOP 20mmHg; aspiration 60 vacuum 700+ mmMg. Group 2: IOP 20mmHg; aspiration 26 vacuum 700+ mmMg. Group 3: IOP 46mmHg; aspiration 26 vacuum 650 mmMg.The following data were analyzed- CDE, aspirated fluid volume, average longitudinal power and average torsional amplitude.

Results:

Mean CDE 4.9, 9.76, 10.37 in group I, II, and III respectively. Mean aspirated fluid volume 73.12ml, 55.05ml and 48.75ml in each group, average longitudinal power consumed 1.14%, 0.42% and 0.66% in each group, average torsional amplitude 27%, 35%, and 51.54% in each group. One way annova showed mean CDE was significantly different with (p<0.05). Regression analysis showed significant reduction of mean CDE in group 1 along with reduced average torsional amplitude.

Conclusions:

Dissociative setting comparison of lowest IOP with highest aspiration and vacuum results in increased deficiency of phocoemulsification.
