Purpose: Association of asthenopia with multiple professions involving prolonged near work is well-established but asthenopia is under-reported in postgraduate surgical trainees. The purpose of this study was to determine the prevalence of asthenopia in surgical trainees and determine the associated risk factors. Methods: This study was an institute-based observational study, conducted between July 2024 and September 2024. Out of 107 surgical trainees, 102 responded to a structured asthenopia questionnaire. Detailed ophthalmic evaluation was performed in 43 trainees who consented and presented voluntarily. Visual acuity (Snellen), cover test (near and distance), positive (PFV) and negative fusional vergence (using a prism bar at near and distance), stereoacuity (Randot), near point of convergence, near point of accommodation and accommodative amplitude (using the Royal Air Force rule) were measured. Statistical analysis was performed using SPSS 22. Results: The prevalence of asthenopia was found to be 67.6%. The highest prevalence was found in Ophthalmology trainees. Out of 43 who presented for orthoptic assessment, 11 were advised to pursue refractive correction. PFV near was significantly lower in trainees with asthenopia (mean = 10.1 PD) compared to those without asthenopia (mean = 15.1), p = 0.03. Conclusion: Asthenopia among surgical trainees was high. The visual precision needed for surgical procedures, lack of sleep and the extensive academic curriculum may contribute to asthenopia in surgical trainees. Routine ophthalmic and orthoptic testing may help alleviate symptoms.
