ABSTRACT

Introduction: The term „Cataract‟ derived from Greek which means „Water fall‟. The senile cataract is the leading cause of Treatable Blindness in world. Our study is limited to the two techniques called “Divide and conquer” and „stop and chop‟. Aims and Objectives: Our study will be designed to compare the "divide & conquer" and "stop & chop" techniques of nucleofractise during phacoemulsification with respect to - Duration of phaco and Energy required. Incidence of corneal edema. Visual outcome in techniques under study. Intraoperative and Postoperative complications during both techniques. Materials and Methods: This study will be designed to compare the „Divide and Conquer‟ technique with that of the “stop and chop” technique with respect to phaco time and energy required, incidence of corneal odema, visual outcome and intraoperative and post operative complications. The work was done on the cases of uncomplicated senile cortical cataract admitted to the Upgraded Department of Ophthalmology, Darbhanga Medical College & Hospital, Laheriasarai, for cataract extraction by phacoemulsification technique. Divide and Conquer Technique Trenching Cracking the Nucleus Stop and Chop technique Central Sculpting Broken into two halves Chopping and Emulsification RESULTS: The average time and effective phaco time required in Divide & Conquer technique was more than stop and chop technique. There was no significant difference statistically among the two technique of nucleotomy (p>0.05). By the end of the study, all the patients in all two groups had the visual acuity of 6/9 or better CONCLUSIONS: Nucleotomy techniques stop &chop and divide& conquer are safe and effective regarding effective phaco time, Post-operative corneal status.One should select any one type of nucleotomy technique and perfect on that particular technique to achieve excellency.

Keywords: Nucleofractise, phaco time, corneal oedema.
