          Abstract

          Objetivo: Analisar os resultados obtidos com a aplicação do programa de ensino de facoemulsificação CBO/ALCON no curso de especialização em oftalmologia do Hospital de Olhos do Paraná. Métodos: Realizou-se um estudo retrospectivo analítico dos resultados das cirurgias de catarata realizadas pelo programa de ensino de facoemulsificação CBO/ALCON que utiliza o método "reverso" em pacientes provenientes do ambulatório do SUS do Hospital de Olhos do Paraná. O programa consta da progressão dos alunos por cinco etapas chamadas de "check points", sendo analisadas as intercorrências per-operatórias em cada um deles, bem como as pós-operatórias. Resultados: Do total de 84 olhos operados, 77 (91,67%) apresentaram acuidade visual (AV) final de 20/40 ou melhor. Entre as intercorrências, a principal delas foi a rotura de cápsula posterior (RCP) e ocorreu em 11 (13,09%) dos 13 (15,48%) olhos que apresentaram algum tipo de complicação. Conclusão: O método "reverso" proposto para o ensino de facoemulsificação pelo programa CBO/ALCON se mostra uma forma de ensino adequada, para o médico residente e seu instrutor, e principalmente para o paciente, devido ao baixo índice de complicações.

          Purpose: To analyze the results obtained with a new phacoemulsification teaching method in the specialization course of Hospital de Olhos do Paraná. Methods: A retrospective study evaluated the results of a "reversal" method used in the CBO/ALCON teaching program at the Hospital de Olhos do Paraná. The method is based on the student progression through five checkpoints starting from the end of the surgery towards the beginning and analysis of intra- and postoperative complications at each one of the checkpoints. Results: Of 84 operated eyes, 77 (91.67%) presented final visual acuity of 20/40 or better. Among the complications, the main one was the posterior capsular rupture and occurred in 11 (13.09%) of 13 (15.48%) eyes with complications. Conclusion: The "reversal" teatching method used in the CBO/ALCON teaching program is appropriate to the student, his instructor, as well as to the patient.

          Extracapsular cataract extraction compared with small incision surgery by phacoemulsification: a randomised trial.

          Cataract extraction constitutes the largest surgical workload in ophthalmic units throughout the world. Extracapsular cataract extraction (ECCE), through a large incision, with insertion of an intraocular lens has been the most widely used method from 1982 until recently. Technological advances have led to the increasing use of phacoemulsification (Phako) to emulsify and remove the lens The technique requires a smaller incision, but requires substantial capital investment in theatre equipment. In this randomised trial we assessed the clinical outcomes and carried out an economic evaluation of the two procedures. In this two centre randomised trial, 232 patients with age related cataract received ECCE, and 244 received small incision surgery by Phako. The main comparative outcomes were visual acuity, refraction, and complication rates. Resource use was monitored in the two trial centres and in an independent comparator centre. Costs calculated included average cost per procedure, at each stage of follow up. Phako was found to be clinically superior. Surgical complications and capsule opacity within 1 year after surgery were significantly less frequent, and a higher proportion achieved an unaided visual acuity of 6/9 or better (<0.2 logMAR) in the Phako group. Postoperative astigmatism was more stable in Phako. The average cost of a cataract operation and postoperative care within the trial was similar for the two procedures. With the input of additional spectacles for corrected vision at 6 months after surgery, the average cost per procedure was pound359.89 for Phako and pound367.57 for ECCE. Phako is clinically superior to ECCE and is cost effective.

            Epidemiology of cataract: accomplishments over 25 years and future directions.

            The purpose of this review is to highlight the advances made by epidemiologic research into cataract. Considerable progress has been made in characterizing phenotypes, determining the prevalence and incidence in various population groups, and understanding risk factors for cataract. Cataract surgery research has documented functional improvements following surgery and has identified aspects of surgery delivery that could be made. Cataract is an independent marker of early mortality, providing a possible system for studying the aging process. Promising future work in cataract epidemiology is highlighted. Despite the availability of cataract surgery, cataract is still the leading cause of blindness worldwide. From a public health standpoint, research that can identify ways to delay onset or progression, or achieve the holy grail of prevention of cataract, should remain a leading priority.

              Visual results and complications of phacoemulsification with intraocular lens implantation performed by ophthalmology residents.

              The authors retrospectively analyzed the visual outcome and incidence of complications of 181 consecutive cases of phacoemulsification performed by eight third-year ophthalmology residents. A posterior chamber intraocular lens was implanted in 179 of these eyes. Vitreous loss occurred in 5.5% of cases. The overall incidence of posterior capsule rupture was 9.9%; of the 18 posterior capsular ruptures, 72% were detected during cortical removal and 22% during nuclear emulsification. Postoperative follow-up for 177 eyes was at least 2 months, and 70% were followed for 6 months or longer. Final best corrected visual acuity of 20/40 or better was obtained in 92.6% of eyes. These results are comparable with previous reports of residents' experience in performing planned extracapsular cataract extraction. With appropriate training and faculty supervision, residents learning to perform phacoemulsification and intraocular lens implantation can achieve acceptable results.
