Comparison between different techniques of phaco emulsifi cation divide and conquer and horizontal chop.
Pak J Surg Jan ;36(2):190-4.

Objective: Comparison between different techniques of phaco emulsification Background: KELMEN in 1967 introduce phaco-emulsification for cataract removal aiming to find a safe and effective way of removing lens. At present phaco-emulsification is the procedure of choice for cataract extraction for most ophthalmologists. Material and Methods: This prospective study include 150 eyes of 150 patients attending the out patient department of Ziauddin Hospital, north campus and Civil Hospital, Karachi. Patient ages between 40 to 60-years with senile cataract, nuclear grade from 2 to 4 under went detail history taking full ophthalmic examination, A&B scan, Corneal pachymetry and endothelial cell count (ECL) and nuclear grading. All patient were operated by the same surgeon using Laurette Alcon Phaco Machine. Study was conducted between 1st June, 2018 to 30th June, 2019. Results: Statically significant endothelial cell loss (ECL) following all study technique. 3-months post-operatively (12.6 & 10.5 in group-I & group-II respectively). The nuclear grade and absolute phaco time had positive correlation with higher ECL whereas age, sex, axial length, did not effect ECL. Significant increase in central corneal thickness (CCT) was observed at immediate post-operative week. Among two study group (14% & 10.5% respectively). Th ere was no statistically significant different between the two groups. Post-operative CCT pachymetry values were return to pre-operative value at 3-months post-operatively. Conclusion: Significant & equal endothelial cell count occur after two study technique. Absolute phaco time and nuclear grade has a positive co relation with higher ECL. Age, sex, and axial length do not effect ECL. CCT increase significantly and equal post-operatively following 2-techniques.
