Background: With the advent of phacoemulsification and other new techniques or innovations in it to give good postoperative results has been progressing steadily. Various methods of nuclear management in phacoemulsification like direct chop and stop and chop helps in reducing ultrasound energy, thereby decreasing surrounding tissue damage and early post-operative recovery. Among the both many surgeons have dissimilar opinions regarding the same, hence a sneak peek into comparison among both techniques is necessary. Objectives: To study phaco parameters which include phaco power, vacuum, aspiration flow rate, effective phaco time in direct chop and stop-and-chop techniques, intra and post-operative complications and to assess post-operative visual acuity. Methods: A prospective interventional study was carried out from December 2017 to June 2019 in which 150 patients who met inclusion and exclusion criteria underwent detailed examination and were divided into Group 1 and 2 equally to undergo phacoemulsification surgery by Direct chop and Stop and chop respectively with similar machine parameters. Intraoperatively EPT and complications noted. Postoperative follow up done. Visual acuity at 4 weeks was recorded. Results: Mean age was 63.06 Y in Group 1 and 63.85 Y in Group 2. There were 22(29.3%) cases with PSC NS1 and 53(70.07%) cases with PSC NS2 in both groups. EPT was the main intraoperative parameter compared. Mean EPT was 2.55s in direct chop group and 2.59s in stop and chop group. Intraoperative and postoperative complications were similar in both groups (p-value 0.98). Of 75 patients in each group, 73(97.7%) in Group 1 and 72(96%) in Group 2 achieved BCVA of 6/6 - 6/9 at the end of 4 weeks. Conclusion: The study showed that both the techniques of phacoemulsification showed equal productive response with regards to surgical duration and post-operative outcome. [ABSTRACT FROM AUTHOR] |
