Abstract :

Statement of the problem: Th ere are various descriptive studies on diff erent techniques of supracapsular phacoemulsifi cation that claim to have lesser risk of complications like posterior capsular rent and nucleus drop and increased risk of corneal endothelial damage compared to conventional in the bag techniques of phacoemulsifi cation. But to the best of our knowledge, there is only one comparative study between supracapsular phacoemulsifi cation and in the bag phacoemulsifi cation. Also, the studies do not describe the effi cacy, safety and functionality of supracapsular phacoemulsifi cation in diff erent grades of nucleus sclerosis. Purpose: To compare the safety and effi cacy of Maloneyâ??s Supracapsular technique with Stop and Chop phacoemulsifi cation in diff erent nucleus sclerosis grades. Methodology: A prospective randomized interventional study comprising of 153 patients undergoing surgery by two techniques, evaluated for intraoperative phacoemulsifi cation parameters, complications and endothelial cell loss and change in morphology (coeffi cient of variation and hexagonality). Findings: Operative time, ultrasound time (41.28 ?±19.20s and 88.41 ?± 43.24s), cumulative dissipated energy (10.18?±5.03 and 24.77?±13.09), eff ective phaco-time, fl uid volume, aspiration time and postoperative corneal thickness (on day-1: 575.72 ?± 57.7 ?µ and 605.88 ?± 57.49 ?µ) were signifi cantly higher in stop and chop group. Endothelial cell loss (on day-1: 7.21% and 7.49%) was signifi cant but comparable in two groups. No diff erence in complication rate. No signifi cant correlation with nucleus hardness was seen with the corneal parameters where as an increase in each phacoemulsifi cation parameter was seen with increase in nuclear hardness, with grade 3 using maximum time and energy. Conclusion & Signifi cance: Supracapsular technique uses less phaco-energy and time and both techniques are comparable with respect to fi nal visual outcome and complications, including corneal edema and endothelial cell loss.

Biography :

Isha Chaudhari is completing her post graduate residency tenure in ophthalmology in University College of Medical Sciences, New Delhi, after giving and passing the fi nal examination. Her interests lie in cataract and oculoplastic surgery. She is learning under the guidance of Professor V. P. Gupta, who specializes in cataract surgeries, oculoplastic, squint and corneal surgeries. He also performs myriad of other surgeries like trabeculectomy, glaucoma drainage devices and dacrocystorhinostomy. He is an avid researcher and has many publications to his name. He is also the Head of Department Ophthalmology and the Principal of the above mentioned college. This research has also been done under his guidance and mentorship.
