Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 6
Abstract
Objective: The purpose of this study was to evaluate the phacoemulsification for various grades of cataract by Peristaltic versus Venturi. Methods: This was a comparative longitudinal study. The study included 112 patients with cataract who underwent cataract extraction by Phacoemulsification by peristaltic pump (Group I) and by Venturi pump (Group II). Group I consisted of 53 patients and Group II consisted of 59 patients. Postoperatively patients were given antibiotic, steroid and mydriatic drops for 6 weeks. Second day, 1 week, 6 weeks, 3 months, 6 months and 1 year follow up was done with postoperative examination which included visual acuity assessment, slit lamp biomicroscopy, tonometry keratometry, direct ophthalmoscopy to see media clartity. The post-operative data was collected at the end of study i.e. at 1 year. Results: Majority of the patients of the both Group I (77.4%) and Group II (81.4%) had cortical cataract. The nuclear hardness of grade 3+ was among more than one third of the patients in both Group I (47.2%) and Group II (45.8%). There was no significant difference in the pre-operative parameters between the groups. There was significant difference (p<0.05) in effective phaco time in both the groups. There was significant difference (p<0.05) in effective phaco time in both the groups. There was no significant (p>0.05) difference in intra and post-operative complications between the groups. Conclusion: The venturi pump was found to be better than peristaltic pump, however, there was no significant difference between the groups in terms of the outcome assessment.
