Impact of accommodation, convergence and stereoacuity on perceived symptoms and surgical performance among surgeons.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMinimally invasive surgery (MIS) is not without impact on surgeons' neck/shoulder/head and eyes. However, the mechanisms for concurrent symptoms are not clear. This study aims to examine the effect of visual impairments on physical symptoms and surgical performance among surgeons performing simulated surgical tasks using two-dimensional (2D) and three-dimensional (3D) viewing modes.
methodsGynaecologists with experience in laparoscopy performed four simulated surgical tasks in the 2D and 3D viewing modes. Visual parameters (accommodation, convergence and stereoacuity) were measured prior to commencement. Objective performance measures were derived from the laparoscopic tasks, and surgeons also self-reported their mental and physical workload using the NASA-TLX. In addition, perceived symptoms were measured using Visual Analogue Scales, the Simulator Sickness Questionnaire and the Computer Vision Syndrome Questionnaire.
resultsSeventeen healthy gynaecologists participated in this study. There were significant relationships between visual impairments and both the perceived symptoms and surgical performance scores of MIS surgeons. Surgeons with a higher number of accommodation/convergence dysfunctions and/or poorer stereoacuity tended to have poorer objective performance scores on simulated surgical tasks in both viewing modes. NASA-TLX scores indicated that surgeons with poorer stereoacuity also perceived themselves to have been less successful at accomplishing tasks. However, these surgeons also reported less intense physical symptoms and simulator sickness.
conclusionsSurgeons' performance for the simulated surgical tasks correlated with visual functions, and it also impacted on the symptoms experienced. Regular screening of surgeons' vision and vision therapy may be required to decrease physical symptoms and improve surgical performance.
