Ozil Phacoemulsification Handpiece versus Phacofragmatome in the Management of Dropped Lens Fragments: A Randomized Controlled Trial

Abstract Purpose In cataract surgery, dislocation of lens fragments into the vitreous cavity is a rare but significant complication. This study compares the effectiveness of the Ozil phacoemulsification handpiece with the traditional phacofragmatome in managing posteriorly dislocated lens fragments to improve patient outcomes. Methods A prospective, randomized study was conducted at a tertiary care hospital in eastern India from January to June 2023, involving 40 patients divided into two groups using block randomisation. Group 1 underwent surgery with the phacofragmatome, while Group 2 used the Ozil handpiece. The primary objective was to evaluate the surgical duration and intraoperative complications, with secondary objectives assessing postoperative Best Corrected Visual Acuity (BCVA), incidence of Cystoid Macular Edema (CME), and safety of surgical sites. Results The use of the Ozil handpiece significantly reduced surgical duration (110 ± 2.54 seconds) compared to the phacofragmatome (152 ± 2.23 seconds, p < 0.001) and minimized the risk of lens fragments falling onto the retinal surface. No significant difference was found in postoperative BCVA or the incidence of CME between the two groups, indicating similar visual outcomes and safety profiles. Conclusion The Ozil phacoemulsification handpiece offers a more efficient and potentially safer alternative for managing posteriorly dislocated lens fragments in cataract surgery compared to the traditional phacofragmatome. These findings suggest the Ozil handpiece could improve surgical outcomes and patient safety.
