Abstract

PURPOSE:TO COMPARE EFFICACY OF LONGITUDINAL U/S PULSE, BURST, CONTINUOUS OZIL&OZIL-IP MODE OF PHACOEMULSIFICATION.

METHOD:RANDOMIZED CONTROLLED PROSPECTIVE STUDY OF 240 GD4 DENSE NUCLEUS,60 EACH IN 4 GROUPS OF LONGITUDINAL U/S PULSE,BURST, CONTINUOUS OZIL & OZIL-IP. PARAMETERS STUDIED WERE CDE,U/S TIME, EFU & POST-OPERATIVE ECC&BCVA.

RESULTS:MEAN CDE WAS SIGNIFICANTLY LOWER(p<0.001) IN LONGITUDINAL U/S BURST MODE (10.29±4.2) Vs PULSE MODE (17.81±3.24),OZIL-IP(18.17±6.96)CONTINUOUS OZIL(22.37±5.36). UST WAS SIGNIFICANTLY LOWER IN LONGITUDINAL U/S BURST (18.19±3.19) Vs OZIL-1P(72.07±16.79), LONGITUDINAL U/S PULSE(78.36±20.74), OZIL(80.23±19.89).POST OPERATIVELY THERE WAS NO SIGNIFICANT CHANGE IN ECC&BCVA IN ALL 4 GROUPS. CONCLUSION:THOUGH INTRA-OPERATIVE CDE&UST IS SIGNIFICANTLY LOWER IN LONGITUDINAL BURST MODE COMPARED TO OZIL-IP,OZIL,&U/S PULSE MODE, HOWEVER IT DOES NOT AFFECT THE POST-OPERATIVE VISUAL RECOVERY EMPHASIZING THE RELEVANCE OF TECHNIQUE IN PHACOEMULSIFICATION.
