RESUMEN
BACKGROUND: Prolonged screen time and abnormal postures can cause backache, neck pain, headache, and finger pain. Studies have shown that excessive usage of gadgets has increased during the coronavirus disease 2019 (COVID-19) pandemic, causing health and ocular hazards. This study used qualitative research methods to understand the health and ocular effects of gadget usage following the COVID-19 postlockdown in optometry students. MATERIALS AND METHODS: A qualitative study using a semi-structured face-to-face interview was conducted for undergraduate and postgraduate students in different optometry institutes who underwent at least 3 months of online teaching learning during the pandemic after obtaining informed consent. The interviews were conducted online; the sessions were audio-recorded, transcribed, and analyzed. Thematic analyses were conducted to understand the challenges faced. RESULTS: Twenty participants were interviewed, of which 70% (n = 14) were females. Thematic analysis identified seven major themes: gadget usage (frequency of usage, type of device, and time spent), challenges during online classes (comprehension, distraction, and network issues), ocular effects (asthenopic symptoms and ocular symptoms), health effects (musculoskeletal disorders), ways to relieve symptoms, recreational activities (breaks and entertainment), and environment and ergonomics (posture and study area and preferred lighting). All the participants reported ocular/health-related symptoms, including eye strain, burning sensation, headache, back pain, finger pain, and neck pain post the lockdown period due to prolonged gadget usage and poor ergonomic postures. CONCLUSIONS: Given the significant increase in digital usage following the pandemic, the study's findings are currently relevant. The prolonged usage of gadgets and poor ergonomic postures have led to ocular and musculoskeletal problems among optometry students. To improve gadget usage without any health-related consequences, students should have access to information regarding ergonomics, increasing the blink rate, and taking regular digital breaks.
RESUMEN
PURPOSE: To report the prevalence of intraocular lens (IOL) opacification and related clinical features in patients implanted with Hydroview IOL. SETTING: Gloucestershire Eye Unit, Gloucestershire, United Kingdom. METHODS: A total of 1330 eyes of 1265 patients who had cataract surgery with Hydroview IOL implantation between September 2000 and April 2001 were reviewed between April and October 2004. The visual acuity, visual symptoms, IOL status, and associated ocular comorbidity were recorded. RESULTS: One hundred ninety-three (14.5%) of 1330 eyes had evidence of IOL opacification. A total of 56 (4.2%) had visually significant opacification and had IOL exchange. The prevalence of IOL opacification ranged from 1.1% in patients who had surgery in September 2000 to 36.3% in the December 2000 group. In eyes with IOL opacification, the visual symptoms were decreased vision (57%), glare (32%), and mistiness of vision (27%). One hundred forty-four eyes (75%) with IOL opacification had visual acuity of 6/12 or better; 21.5% of diabetic eyes had IOL opacification compared with 14.3% of nondiabetic eyes (P =.06); 20.5% of glaucomatous eyes had IOL opacification compared with 14.0% of nonglaucomatous eyes (P = .033). CONCLUSIONS: This is the first large sample recall of patients implanted with the Hydroview H60M IOL. The overall prevalence of IOL opacification was 14.5%, with peak prevalence in patients who had surgery in December 2000.

We report our observation of a distinct membrane on the posterior surface of the Hydroview (Bausch & Lomb Surgical) intraocular lens during laser capsulotomy in 6 patients. In 3 patients, the retrolental membrane was noted during 4 to 6 weeks of follow-up after laser capsulotomy. The technique of a 2-stage laser capsulotomy in this group of patients is described. The possible cause and significance for this observation are also discussed.
