AI Article Synopsis
- - The study aimed to assess the efficiency of venturi versus peristaltic pump phacoemulsification systems in patients undergoing laser cataract surgery at Mercy Health System in Springfield, MO.
- - Key metrics analyzed included energy use, ultrasound time, and total phaco tip time during surgery, with findings showing the venturi system required less energy and time compared to the peristaltic system.
- - The results indicated that the venturi system was more efficient overall with no significant differences in complications between the two systems, based on data from 995 eyes.
Article Abstract
Objective: To compare the efficiency of venturi and peristaltic pump phacoemulsification systems in patients undergoing routine laser cataract surgery.
Design: Single center, nonrandomized clinical study.
Participants: The study compared consecutive eyes with moderate nuclear sclerosis undergoing routine laser cataract surgery at the Outpatient Eye Center, Mercy Health System, Springfield, MO, USA.
Methods: Each surgery used the same femtosecond laser settings. Surgeries were performed with either a venturi or peristaltic vacuum system by a single surgeon (WJS). The EFX, percent power, ultrasound time (UST), the total time that the phaco tip was in the eye (phaco tip in/out time, PIOT), and the surgery time (speculum in/out time) were recorded. Exclusions and intraoperative complications were also analyzed.
Results: 995 eyes were included in the study. The EFX in the venturi eyes (1.7 ± 1.3; n = 521) compared to peristaltic eyes (2.1 ± 1.4; n = 474) was lower (p < 0.0001). Similarly, the UST in the eyes performed with the venturi system versus the peristaltic system was reduced (32.4 ± 22.3 s vs 40.7± 25.7 s; p < 0.0001). The PIOT in the venturi group compared to the peristaltic group was less (71.1 ± 31.1 sec vs 79.1 ± 36.1 s; p = 0.0002). The case time (speculum in/out time) was lower for the venturi eyes (307.2 ± 68.8 s vs. 311.6 ± 53.6 s; p = 0.268).
Conclusion: In eyes undergoing routine laser cataract surgery, the use of the venturi pump system was more efficient compared to the peristaltic pump system based on energy use and time, and there was no significant difference in complications.

Outcome of a Mix-and-Match Approach with a Monofocal Aspherical and a Bifocal Extended Depth-of-Focus Intraocular Lens to Achieve Extended Monovision in Cataract Patients.

Background: Extended monovision is a novel mix-and-match approach that has been recently introduced. It involves implanting an aspherical monofocal intraocular lens (IOL) for distance vision in the dominant eye, and a bifocal extended depth-of-focus (EDOF) IOL in the nondominant eye. The target refraction for the nondominant eye is - 1.

Purpose: To investigate potential modes of programmed cell death in the lens epithelial cells (LECs) of patients with early age-related cortical cataract (ARCC) and to explore early-stage intervention strategies.
Methods: Anterior lens capsules were collected from early ARCC patients for comprehensive analysis. Ultrastructural examination of LECs was performed using transmission electron microscopy.

Purpose: We report a single case of ocular decompression retinopathy (ODR) following neodymium-doped yttrium aluminum garnet laser peripheral iridotomy (Nd:YAG LPI) for primary acute angle-closure glaucoma associated with delayed visual recovery secondary to optic nerve head edema and macular thickening.
Observations: A 56-year-old female patient presented to the emergency department with primary acute angle-closure glaucoma. After topical and IV therapy did not improve intraocular pressure (IOP), an Nd:YAG LPI was performed.
