Outcome of pediatric cataract surgery including color vision, stereopsis, and cognition in a tertiary eye care center in India.
Article in Oman journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPediatric cataract is an important cause of avoidable childhood blindness in India. Although there are studies on clinical features and visual acuity outcomes of pediatric cataract surgery, there are no studies that look into aspects of color vision, stereopsis, and cognitive functions in children with cataracts. Studying these parameters pre- and postsurgery will help us assess the overall components of visual function that are critical for the child's development. With this in mind, we aimed to study the clinical features, outcome of treatment, color vision, stereopsis, and cognitive functions in children with cataracts. MATERIALS AND
methodsDesign: Hospital-based prospective descriptive study. Data of 68 children (0 < 18 years) were collected, on the clinical features, visual acuity, color vision, stereopsis, and social and intelligence quotient before and after surgery. Data analysis was performed using Graph Pad Prism software version 9.4.0 (673).
resultsNinety eyes of 68 children (36-bilateral/32-unilateral) were operated. A total of 46 children were available at 6 months' follow-up (28 bilateral cataracts (46 eyes) and 18 unilateral cataracts). Nineteen (67.8%) of the bilateral, had a best corrected visual acuity of 6/6-6/18 in the better eye and nine (50%) of the unilateral had a visual acuity of 6/18-6/6 in the operated eye. Preoperatively, 61.5% of the children had a stereopsis of 100-600 arc-secs. Post-operatively, 84.4% of the children had a stereopsis in the range <50-600 arc-secs. All children had color vision deficiency. Preoperatively, 62% of the children had strong and moderate deficiency, whereas postoperatively, 66.6% had mild deficiency. We found negative correlation (
conclusionMajority of the children had improved visual acuity after surgery. This outcome can be extrapolated to the overall improvement in stereopsis, color vision, and higher cognitive functions.
