“…This is similar to studies by Isawumi et al [18] and Adewoye et al [19] Although participants were significantly skewed towards females, gender showed no statistically significant association with intraoperative complications or postoperative UCVA. In a large retrospective series of 79,777 patients by Aravind et al [4], sex (P = 0.42) and age (P = 0.21) were not significantly associated with intraoperative complications.…”

Abstract:Purpose: To appraise the learning pattern in Manual Small Incision Cataract Surgery (MSICS) of a trainee ophthalmologist. Setting: Sankara Eye Hospital, Pammal, Chennai, India. Design: Retrospective study. Methods: Case files of patients who underwent MSICS during the training were reviewed. Surgical complications, nucleus density, extent of supervisors' intervention in surgeries and visual acuity were either tabulated or graphically presented. Two-way ANOVA and multiple regressions were used to compare dependent variables. Results: There were 123 eyes of 123 patients {males 49 (39.8%), females 74 (60.2%)}. The mean age was 63.19 + 6.6 years with a range of 40-80 years. The worst postoperative visual acuity (VA) was in the first month of training. With an overall complication rate of 30.9%, posterior capsular rent (PCR) was most prevalent in eyes operated in the first month of training (3 of 18 eyes, 16.7%). Supervisors' intervention in surgeries was highest in the first month of training and declined as training progressed. Fischer's Exact test for intraoperative complications and extents of supervision showed a statistically significant (P = 0.012). Multiple logistic regression analysis showed that density of nucleus was statistically significant (P = 0.02). Conclusions: Three months appear sufficient for learning the surgical rudiments of MSICS for a trainee with a modest competence in Extra-capsular Cataract Extraction (ECCE), especially if surgeries are performed on a continuous basis during the period.

“…La moyenne d’âge des patients est variable dans la littérature, suivant les critères d'inclusion. Nous avons inclus des patients d'au moins 40 ans et avons retrouvé une moyenne d’âge de 66 ans qui est proche de la littérature [ 6 , 7 ]. Cette moyenne d’âge est plus élevée dans les pays occidentaux pour les cataractes séniles du fait de leur survenue plus tardive.…”

La cataracte est la première cause de cécité curable dans le monde. Son traitement est chirurgical. Le but de notre travail a été d’évaluer les résultats de la phacoalternative ou la chirurgie de la cataracte à petite incision. Il s'est agi d'une étude transversale descriptive à collecte prospective allant du 1er janvier au 31 septembre 2014, chez des patients âgés d'au moins 40 ans. Les données socio-démographiques, l'acuité visuelle, l'astigmatisme et les complications ont été évalués. Nous avons inclus 300 yeux de 286 patients. L’âge moyen était de 66 ans (écart type 9,93) avec une prédominance masculine de 57,7%. Les co-morbidités étaient dominées par l'hypertension artérielle 30,33% des cas. L'acuité visuelle pré-opératoire était de moins de 1/20è dans 70, 7% des cas. En biométrie, la puissance moyenne était de 21,50 dioptries. L'implant posé a été adéquat dans 60%. Les principales complications per-opératoires étaient le chémosis post-anesthésie 4,67% et l'issue de vitrée moins de 2% des cas. Les complications post opératoires précoces ont été dominées par l’œdème de cornée 26,33%, et les complications tardives par la cataracte secondaire. L'astigmatisme induit était de 1, 12 dioptrie en moyenne (écart type 1,26). Sans correction, les résultats visuels étaient mauvais dans moins de 1%, limites dans 31%, et bons 68% suivants les normes de l'Organisation Mondiale de la Santé. La phacoalternative donne des résultats satisfaisants, avec peu de complications. L'amélioration du plateau technique et la disponibilité d'implants adéquats pourraient les améliorer.

“…Bifocal IOLs create two focal points for near and far distance, and thus intermediate VA is less than the near or far VA ( 8 – 10 ). However, intermediate vision is increasingly important because screen work has become present in nearly everybody's everyday life ( 4 , 11 ). More recently, trifocal IOLs have been developed to supply the visual function at the intermediate distance ( 12 ), which is regarded as an important factor in patient satisfactory outcomes, specifically for those with extended computer use and higher patient expectations ( 13 ).…”

The comparative efficacy of trifocal and bifocal intraocular lenses (IOLs) remained uncertain among patients undergoing cataract surgery. A systematic review and meta-analysis was performed to answer this question. PubMed, Cochrane Library and Embase were searched to capture relevant randomized controlled trials (RCTs). Visual acuity (VA) and patient's satisfaction were regarded as primary outcomes. Secondary outcomes included residual sphere, spherical equivalence, residual cylinder, posterior capsular opacification (PCO), spectacle independence, and other complications. Statistical analysis was done using RevMan 5.2.0. A total of 9 studies (11 RCTs) with 297 participants (558 eyes) were included. Meta-analysis showed significant differences between trifocal and bifocal IOLs in the uncorrected near VA (mean difference [MD], −0.008; 95% confidence interval [Cl], −0.015 to −0.001; P = 0.028) and uncorrected intermediate VA (MD, −0.06; 95% CI, −0.10 to −0.02; P < 0.01). Trifocal IOLs were associated with decreased PCO incidence when compared to bifocal IOLs (relative risk [RR], 0.54; 95% CI, 0.31 to 0.95; P = 0.03). Trifocal IOLs may be superior to bifocal IOLs because of its improved intermediate VA and reduced incidence of PCO.
