Effect of the COVID-19 pandemic on cataract surgery by residents who had routine surgical simulator training during residency.

PURPOSE: To assess the effect of the Coronavirus disease 2019 (COVID-19) pandemic on cataract surgery by residents who had mandatory surgical simulator training during residency. METHODS: In this retrospective, observational analytical study, the total number of cataract surgeries and surgical complications by all senior residents of 2019 (2019 class; prepandemic) and 2020 (2020 class; affected by the reduced number of elective surgeries due to the COVID-19 pandemic) were collected and compared. All residents had routine mandatory cataract surgery training on a virtual surgical simulator during residency. The total score obtained by these residents on cataract challenges of the surgical simulator was also evaluated. RESULTS: The 2020 and 2019 classes performed 1275 and 2561 cataract surgeries, respectively. This revealed a reduction of 50.2% in the total number of procedures performed by the 2020 class because of the pandemic. The incidence of surgical complications was not statistically different between the two groups (4.2% in the 2019 class and 4.9% in the 2020 class; p=0.314). Both groups also did not differ in their mean scores on the simulator's cataract challenges (p<0.696). CONCLUSION: Despite the reduction of 50.2% in the total number of cataract surgeries performed by senior residents of 2020 during the COVID-19 pandemic, the incidence of surgical complications did not increase. This suggests that surgical simulator training during residency mitigated the negative effects of the reduced surgical volume during the pandemic.

Astigmatism Profile in a Large Series of Brazilian Patients.

PURPOSE: To assess anterior, posterior, and total corneal astigmatism in a large sample of Brazilian patients. METHODS: In this retrospective cross-sectional study, all patients whose corneas were imaged with the Galilei G6 (Ziemer Ophthalmology) between January 2017 and February 2019 at HOPE Eye Hospital, in Recife, Brazil, were eligible to participate. Anterior, posterior, and total corneal astigmatism values were collected and analyzed. RESULTS: The study included 3,253 eyes of 1,919 patients. The mean magnitude of the anterior, posterior, and total corneal astigmatism was 1.50 ± 1.11, 0.34 ± 0.15, and 1.29 ± 0.98 diopters (D), respectively. Corneal astigmatism was greater than 0.50 D in the anterior cornea of 86.3% of eyes (2,807 eyes) and in the posterior cornea of 13.2% of eyes (429 eyes). Vertical alignment of the steepest corneal meridian was observed in the anterior cornea of 74.5% of eyes (2,423 eyes) and in the posterior cornea of 93.1% of eyes (3,029 eyes). The correlation between the astigmatism magnitude of the anterior and posterior cornea was strong when the steep anterior meridian was aligned vertically (r = 0.720; P < .001), and absent when it was aligned horizontally (r = 0.102; P = .036). CONCLUSIONS: Corneal astigmatism values in the Brazilian population were similar to those found in other ethnicities, suggesting that toric calculators, nomograms, coefficients of adjustment, and formulas that were developed based on astigmatism values of other populations may be used in Brazilian patients with comparable accuracy.

Effects of COVID-19 pandemic on stress level of residents and fellows during ophthalmology training.

Purpose: To evaluate the impact of coronavirus disease 2019 (COVID-19) on the mental health of residents and fellows in ophthalmology. Methods: A questionnaire composed of 42 questions was applied to Brazilian residents and fellows in Ophthalmology. The questionnaire addressed the demographics of participants, their working conditions before and during the COVID-19 pandemic, and the Perceived Stress Scale (PSS-10). Results: The study had a total of 271 participants in Ophthalmology training, from which 100 were fellows and 171 were residents. Before the pandemic, Ophthalmology residents and fellows had a higher workload (P < 0.001), and residents worked more hours than fellows (P = 0.001). During the pandemic, the workload of both residents and fellows decreased and equalized (P = 0.195). No correlation was found between the working hours during the pandemic and their stress level were observed (P = 0.760). Higher stress scores were identified in women ophthalmologists (P = 0.001) as well as in residents and fellows that had their surgical training interrupted during the pandemic (P < 0.001). Conclusion: The stress level of residents and fellows during the COVID-19 pandemic was similar, however, those that had their surgical training interrupted during the pandemic presented higher level of stress. Female physicians also presented higher level of stress compared to male physicians.

Prevalence of macular abnormalities identified only by optical coherence tomography in Brazilian patients with cataract.

PURPOSE: To assess the prevalence of macular abnormalities not suspected by the biomicroscopic fundus examination and identified only by macular optical coherence tomography (OCT) in the preoperative evaluation for cataract surgery in a large series of Brazilian patients. SETTING: Private practice, Recife, Brazil. DESIGN: Retrospective case series. METHODS: All eyes that had cataract surgery by the same physician between August 2014 and July 2016 were eligible. Excluded were eyes with a previous diagnosis of macular abnormalities, with a suspicious biomicroscopic fundus examination, and without OCT results. Based on the preoperative macular OCT, patients were divided into the following 2 groups: those with a normal OCT and those with an abnormal OCT. RESULTS: Nine hundred fifty-two eyes (614 patients) were included in the study. Macular OCT identified abnormalities in 47 eyes (4.9%) of 44 patients (7.2%). Thirty-one eyes (3.3%) had epiretinal membrane, 7 (0.7%) had age-related macular degeneration, 4 (0.4%) had intraretinal cysts, 4 (0.4%) had a lamellar hole, and 1 (0.1%) had a macular hole. Patients with an abnormal OCT had a statistically significant higher mean age (P = .004). CONCLUSION: In the preoperative evaluation for cataract surgery in Brazilian patients, 7.2% of those with a normal biomicroscopic fundus examination had macular abnormalities that were identified only by OCT.
