Article Abstract
Objectives: To evaluate YAG capsulotomy rates following implantation of two types of trifocal intraocular lenses (IOLs).
Methods: In this retrospective cohort study consecutive patients who underwent cataract surgery with a trifocal IOL from 1st May 2017 to 30th October 2019 at Aga Khan University Hospital, Karachi were included. Eyes which either had an AT Lisa Tri or Alcon PanOptix IOL implant were included. The primary outcome measure was Nd: YAG laser. Univariate analysis of all predictor variables was performed followed by a multivariate regression analysis of those which were significant. A p-value of < 0.05 was taken as significant.
Results: A total of 328 eligible eyes were identified. Nine eyes were excluded. Out of the 319 eyes of 177 patients included in this study, 180 received AT Lisa Tri while 139 of them received Alcon PanOptix Trifocal IOLs. The mean (SD) age of the patients was 52.29 years (±11.04). Gender was equally distributed with 91(51.4%). male patients. Median (IQR) time to laser capsulotomy was 8 months (3-16). Clinically posterior capsular opacification (PCO) was present in 75(23.5%) eyes. A total of 39(12.2%) eyes underwent Nd: YAG laser capsulotomy. Among the AT Lisa Tri group 29 (16.1%) eyes underwent laser capsulotomy compared to 10 (7.2%) (n=10) in Alcon PanOptix group (p=0.016). In both univariate and multivariate analyses, gender and IOL type were statistically significant.
Conclusions: Eyes implanted with AT Lisa Tri showed a significantly increased rate of YAG capsulotomy. A prospective randomized control trial is recommended to confirm these findings.

Impact of central corneal astigmatism on postoperative visual outcomes in patients undergoing trifocal intraocular lens implantation.

Background: To investigate the impact of central corneal astigmatism on postoperative visual outcomes in patients with trifocal intraocular lens (IOL) implantation.
Methods: This retrospective study included 278 eyes of 278 patients who underwent uneventful cataract surgery with implantation of the trifocal IOL (AT LISA tri 839MP). Patients were divided into two groups according to the total corneal refractive power (TCRP) in 3 mm zone centered on the corneal apex: low astigmatism group, TCRP ≤ 0.
A Comparative Analysis of the Effects of Misaligning Different Trifocal Intraocular Lenses.

This laboratory study aims to assess the effects of misaligning different trifocal intraocular lenses (IOLs) under varying spectral and corneal spherical aberration (SA) conditions. With an IOL metrology device under monochromatic and polychromatic conditions, the following models were studied: AT ELANA 841P, AT LISA Tri 839MP, FineVision HP POD F, Acrysof IQ PanOptix, and Tecnis Synergy ZFR00V. The SA was simulated using an aberration-free and average-SA cornea.

School of Health, Concordia University, Montréal, Québec, Canada.
Background: Physical characteristics and perceptions of an environment can have enduring effects on one's mental health. The present study aimed to determine whether a set of measures of neighborhood safety - independent built environment features, parents' perception of neighborhood safety and community cohesion, and children's perception of neighborhood safety - best related to symptoms of depression in young boys and girls from Montréal, Québec.
Methods: Data were from the Quebec Adipose and Lifestyle Investigation in Youth (QUALITY) cohort.
Purpose: To assess visual outcomes and stability of lens alignment more than 3 years after implanting either the AT Lisa Tri Toric (Carl Zeiss Meditec) or the Acrysof IQ Restor Toric (Alcon Laboratories, Inc) intraocular lens (IOL).
Methods: Patients who had received either the AT Lisa Tri Toric or the Acrysof IQ Restor Toric IOL were included in the study. The average follow-up period was 5.
