Background: Hard brunescent nuclei are difficult to chop with traditional techniques, because leathery tough strands may connect the posterior surface and span across the fragments, which poses a challenge to completely divide the nuclei. The ultra-chopping technique was designed to mitigate this issue. Purpose: To compare the intraoperative parameters between Ultra-Chopper and Divide & Conquer Techniques. Setting: This study was performed at Hospital Oftalmológico de Brasília, Brasília, DF, Brazil. Patients and Methods: A prospective, randomized and comparative study. Patients with the diagnosis of dense cataract and surgical extraction programmed were divided into two groups: Ultra-Chopper and Divide & Conquer. Intraoperative data were collected and submitted for the statistical analysis. Results: 36 eyes were included, 19 eyes with Ultra-Chopper and 17 eyes with Divide & Conquer. Groups were statistically equivalent in age and nucleus density. There were no surgical complications. Torsional time and cumulative dissipated energy were significantly reduced in the ultra-chopper group. The ultra-chopper group had less total case time, fluid usage and aspiration (ASP) time. Conclusion: The ultra-chopper tech- nique can reduce ultrasound energy dissipation during cataract surgery, and decrease case time, fluid usage and ASP time.

Evaluation of the Effectiveness of Preloaded IOL Injectors in Surgical Time

Open Journal of Ophthalmology 2021年第4期11卷 339-347页

Background: The implantation of the intraocular lens (IOL) is still subject to error and complication, as it can result in traumatic opening of the IOL leading to rupture of the posterior capsule and zonular dialysis, it takes time to train paramedic teams to assemble such IOLs with the manual injectors. Moreover, there is a potential risk of comtamination and endophthalmitis as there is manipulation of the IOL and cartridge. The preloaded IOLs tend to reduce those unwanted results and may optimize the surgical time. Purpose: The aim of this study is to compare the effectiveness and implantation time between three injectors and three intraocular lenses, two pre-loaded and one conventional. Methodology: Videos of thirty patients undergoing cataract surgery from December 2019 to December 2020 at the Hospital Oftalmológico de Brasília (HOB), Brasília, Brazil were included in this observational, analytical retrospective study, non randomized. All patients had their surgeries recorded, from which the time of injection and opening of the intraocular lens (IOL) was extracted, 20 eyes were implanted with preloaded intraocular lens, and 10 eyes with conventional IOL implant. The patients were divided into three groups with similar eye characteristics. The first received the AutonoMeTM (CE) injector with the Clareon® IOL, the second the IsertTM injector (I) with the Hoya® IOL, and the third was injected with Johnson & Johnson Platinum 1 Series injector used to deliver Sensar
