OUTCOME COMPARISON OF TORSIONAL MICROCOAXIAL PHACOEMULSIFICATION USING 30 AND 45 DEGREE APERTURE ANGLE NEEDLE
Journal Title: IJAR-Indian Journal of Applied Research - Year 2017, Vol 7, Issue 9
Abstract
Aims: To assess and compare the postoperative outcomes of torsional microcoaxial phacoemulsification surgeries performed using 30 and 45 degree aperture angled needles. Materials and methods: This randomized, single blinded comparative follow up study was conducted on 80 patients attending Eye OPD diagnosed with uncomplicated senile cataract. Result & analysis: Group A (40 eyes of 40 patients) underwent coaxial torsional phacoemulsification using 45 degree aperture angle & Group B (40 eyes of 40 patients) using 30 degree aperture angle. Both the groups were similar in terms of age, sex, cataract grade and the eye which was operated. (P> 0.05 for each of them).We found lower values of CDE and total UST during the surgery in Group A which were statistical significance with P values =0.0010 and 0.027s respectively. Volume of BSS used in group A was high than in group B but the difference was not statistically significant with P values = 0.214. Mean Endothelial cell loss was higher in Group B in all postoperative visits of 1 week, 1 month and 3 month but this difference was statistically significant only at 1 week post op with P value 0.04 at 1 week , 0.248 and 0.815 at 1 month and 3 month respectively. We found better values of BCVA in group A than group B but the difference was not statistically significant with P values at 1 week, 1 month , and 3 month were 0.20 , 0.09, 0.546 and 0.058 respectively. Conclusion : This suggest that phacoemulsification using 45 degree needle may be slightly superior than 30 degree in terms of total energy dissipated in eyes but the final clinical result is not clinically significant or superior.
