Abstract

PURPOSE: This review emphasizes the effect of light on visual efficiency, the impact of different lighting focuses, types of lighting, and their influence on vision and productivity. Light sources and standards are intriguing subjects for ophthalmologists. Guidelines regarding the level of lighting influence on visual activities can enhance visual performance.
METHODS: This article was developed based on literature reviews, with a bibliographic survey conducted in databases such as PubMed, MEDLINE, Web of Science, Embase, LILACS, and SciELO.
RESULTS: Provides recommendations for understanding information regarding the influence of lighting on visual performance.
CONCLUSION: Proper workplace lighting is crucial for improving visual efficiency, safety, productivity, and worker health. Efficient workplace lighting should avoid light sources directed towards the worker's face, prevent harmful glare, be more intense in the work area, and uniform in the rest of the room. Ophthalmologists should be knowledgeable about and provide guidance on correct lighting to ensure patient comfort and satisfaction with visual correction.

Abstract

PURPOSE: The OrbiTau surgical simulator is a synthetic eye model developed to enhance cataract surgical training. Herein, we aimed to describe the perspectives of Harvard’s Ophthalmology faculty and residents regarding the effectiveness of OrbiTau.
METHODS: A cross-sectional study was conducted in which 11 surgeons from the Massachusetts Eye and Ear Infirmary, with prior experience utilizing simulated phacoemulsification platforms, conducted cataract surgery with the OrbiTau. Subsequently, they completed a satisfaction questionnaire using the Likert scale.
RESULTS: Regarding the various OrbiTau components, 90.90% of the participants reported that the OrbiTau lens capsule was comparable to that of the human lens during capsulotomy. Furthermore, 72.72% of the participants found that the OrbiTau lens consistency was analogous to that of the human lens nucleus. Approximately 63.63% of the participants reported that the model’s posterior lens capsule resembled the native posterior capsule, and 72.72% of the participants noted that the model’s red reflex was similar to that of the dilated human pupil. Most participants believed that the OrbiTau was easier to use and more realistic than other commercially available simulators.
CONCLUSION: Our single-institution survey of the Orbitau demonstrated that this model realistically replicates ocular structures and may be a viable option for cataract surgery training.

Abstract

PURPOSE: In Brazil, it has traditionally been standard practice to teach a wide range of surgical techniques to all ophthalmology residents, with the aim of equipping them to manage most ocular conditions. However, with modern developments, access to subspecialists has expanded to nearly the entire country. This raises the question of whether it is still necessary to teach numerous surgical techniques to every resident. This study evaluates the effectiveness of surgical training in Brazilian ophthalmology residency programs to determine if comprehensive surgical training for all residents is truly effective, thereby providing evidence to inform educational policy decisions.
METHODS: A cross-sectional study using a questionnaire distributed to physicians engaged in eye care.
RESULTS: A total of 137 physicians responded to the survey, with 104 (76.0%) having already completed their specialization. The findings indicate that most practicing ophthalmologists received surgical training during residency in cataract, glaucoma, oculoplastic, and strabismus surgeries. Nonetheless, many of these specialists no longer perform most of these surgeries in practice, except for cataract surgery. While 53.8% of those who completed residency reported satisfaction with their training, 35.6% indicated that they wished they had received better surgical preparation.
CONCLUSION: The training of ophthalmology specialists must be made more efficient. Training efficiency is reduced when time and resources are devoted to surgical procedures that many specialists will not perform in their careers.
