Corneal endothelial cell loss with different techniques of nucleus delivery in Manual Small Incision Cataract Surgery- Randomized Controlled Trial.
Article in Journal of cataract and refractive surgery, 2024. 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
purposeTo compare corneal endothelial loss in manual small incision cataract surgery (MSICS) following three different techniques of nucleus delivery (Viscoexpression, Irrigating Vectis, Phacosandwich).
settingMahatma Gandhi Medical College and Research Institute, Puducherry, India.
designProspective, single blinded, randomized controlled trial.
methodsWilling patients > 40years of age with immature cataract and posted for MSICS were recruited for the study. Those with systemic or ocular comorbidities which may influence corneal endothelium, dilated pupil size of <5mm, intraoperative complications and postoperative corneal haze were excluded. They were randomly divided to one of the three groups (Group 1- Viscoexpression, Group 2- Irrigating Vectis, Group 3- Phacosandwich) for nucleus delivery. Visual acuity and corneal endothelial parameters were recorded preoperatively and postoperatively at 6-8weeks.
resultsA total of 90 patients with mean age of 59.13 ± 9.42 years (range 40-82years) were studied with 30 patients in each group. Following MSICS there was a 12.12% (p=0.001) endothelial cell loss. It was 10.81% in viscoexpression group, 11.3% in irrigating vectis group and 14.28% in phacosandwich group. Post hoc analysis with Dunn Bon ferroni test showed endothelial cell loss following viscoexpression and irrigating vectis methods of nucleus delivery were comparable (p=0.096) and significantly lesser (p<0.001) than in Phacosandwich group.
conclusionThere was significant endothelial cell loss following MSICS. Nucleus delivery by viscoexpression and irrigating vectis had similar endothelial cell loss while it was greater with phacosandwich technique.
