By Tahira Hafeez, Maham Irshad and Saher Irshad


OBJECTIVE: purpose of study was to determine causes of posterior capsular rupture during phacoemulsification.Study Design: it is a retrospective study.Duration of study: In this study data was taken of previous 7 months from January 2018 to July 2018.Setting: Study was conducted in Ophthalmology ward of Bahawal Victoria Hospital Bahawalpur Pakistan.Patients and Methods: Total 62 cases were studied. These cases were admitted in the ward on opd bases. A Proforma was designed for documenting all data related to the patient. Proper written consent was taken from in charge of the ward for conducting this study. Data was collected from previous record of the ward. Only those cases were included in the study having complete data mentioned in the record rest of the cases with incomplete data were excluded from the study. These patients were admitted for phacoemulsification and complications were reported. Follow up of these cases was made for observing post operative outcome. Causes of capsular rupture included trauma by chopper, dialing of intra ocular lens and implantation of intra ocular lens. Results were calculated in the form of frequencies and data was analyzed using Microsoft office and SPSS version 2007. Data was expressed in the form of tables and graphs.Results: There were 190 cases which underwent phacoemulsification during given period of study on elective basis. These cases were admitted and prepared for surgery after taking anesthesia fitness etc. Complete data of these cases was collected from previous record of the ward. Their operation noted and all investigations, indication of surgery and all investigations and procedure notes were seen. Out of these 190 cases 62(32%) cases developed complications related to the procedure. Posterior capsular rupture was reported in these cases due to different reasons. Most common cause of this complication was heated phacoemulsification tip in 25 cases. In 9 patients rotation of nucleus was its cause. Out of these 62 cases 6(9.7%) cases got capsular rupture during lens implantation, in 11(17.7%) cases trauma by simco cannula, in 8(12.9%) cases capsular rupture occurred during dialing of intra ocular lens.  Trauma by chopper tip occurred in 3(4.8%) cases. It was seen that most common cause of lens rupture was heated phacoemulsification tip followed by rotation of nucleus second most common cause.    Conclusion:  During phacoemulsification  we should take care throughout the procedure as capsular rupture may happen in any stage of the procedure. Osmotic balance of lens and surrounding environment is most important. Heated tip of phacoemulsification is the major cause of rupure of lens
