AI Article Synopsis
- The study aimed to assess patient outcomes and visual function after implanting trifocal and trifocal toric intraocular lenses (IOLs) with the help of intraoperative aberrometry.
- The research involved 21 participants who had cataracts, with a focus on post-operative visual acuity and various visual performance metrics over a 3-month follow-up period.
- Results showed that nearly all subjects achieved good visual acuities at different distances, and most had minimal prediction errors and low residual astigmatism, although some activities like night driving and reading small text presented challenges for some individuals.
Article Abstract
Purpose: To evaluate patient outcomes and visual function following trifocal and trifocal toric intraocular lens (IOL) implantation using intraoperative aberrometry at a single site in the US.
Methods: This prospective, single arm study included 21 subjects that completed 3 month follow-up. Inclusion criteria were visually significant cataract and potential post-operative visual acuity of 20/25 or better. Endpoints included postoperative prediction error, refractive outcomes, uncorrected visual acuities at distance (UDVA), intermediate (UIVA), and near (UNVA), contrast sensitivity, and subject responses on the modified Visual Function Quality of Life Questionnaire (VF-14 QOL).
Results: Binocular UDVA, UIVA, and UNVA were 20/25 or better in 100% (21/21), 100% (21/21), 90% (19/21) of subjects. The absolute prediction error was 0.50 D or less in 79% (33/42) of eyes, and 81% (34/42) and 86% (36/42) of eyes achieved ≤0.5 D of residual astigmatism and manifest refraction spherical equivalent, respectively. On the modified VF-14 QOL, driving at night, reading small print, and reading a newspaper or book were the tasks that had the lowest percentages of subjects reporting no difficulty or a little difficulty.
Conclusion: Implantation with trifocal and trifocal toric IOLs using intraoperative aberrometry can provide high refractive precision, leading to excellent visual performance and low visual task difficulty at all ranges (distance, intermediate, and near).

Mass Casualty Incident Training in Immersive Virtual Reality: Quasi-Experimental Evaluation of Multimethod Performance Indicators.
J Med Internet Res
January 2025
Psychological Institute and Network Aging Research, Heidelberg University, Heidelberg, Germany.
Background: Immersive virtual reality (iVR) has emerged as a training method to prepare medical first responders (MFRs) for mass casualty incidents (MCIs) and disasters in a resource-efficient, flexible, and safe manner. However, systematic evaluations and validations of potential performance indicators for virtual MCI training are still lacking.
Objective: This study aimed to investigate whether different performance indicators based on visual attention, triage performance, and information transmission can be effectively extended to MCI training in iVR by testing if they can discriminate between different levels of expertise.
Artificial Intelligence in Predicting Ocular Hypertension After Descemet Membrane Endothelial Keratoplasty.

Institute of Vision Research, Department of Ophthalmology, Yonsei University College of Medicine, Seoul, Korea.
Purpose: Descemet membrane endothelial keratoplasty (DMEK) has emerged as a novel approach in corneal transplantation over the past two decades. This study aims to identify predisposing risk factors for post-DMEK ocular hypertension (OHT) and develop a preoperative predictive model for post-DMEK OHT.
Methods: Patients who underwent DMEK at Gangnam Severance Hospital between 2017 and 2024 were included in the study.

Background And Purpose: The objective was to examine the adjuvant effect of active pulsed electromagnetic field (PEMF) versus microwave (MW) therapy, as well as sham PEMF, in addressing pain and improving functionality for treating knee osteoarthritis (KOA).
Methods: This was a double-blind, placebo-controlled, randomized clinical trial. Individuals diagnosed with KOA were assigned to an intervention combining an exercise program (EX) with active PEMF, MW, or sham PEMF.

Background: Few studies reported the long-term clinical outcomes and joint degeneration of patients with chronic lateral ankle instability (CLAI) and small osteochondral lesions of the talus (OLTs) following simultaneous open modified Broström-Gould (MBG) surgery and arthroscopic bone marrow stimulation (BMS). The purpose of this study was to study the long-term results of patients after BMS and BMG surgery, and to further evaluate the potential effect of OLT size on postoperative results.
Methods: In this retrospective study, 110 CLAI patients were divided into 57 patients with OLTs (including 24 patients having combined small osteochondral lesions of the tibial plafond) receiving simultaneous BMS and MBG surgeries (BMS+MBG group), and 53 patients without OLTs receiving isolated open MBG surgery (MBG group).
