Light sensitivity and pain sensation during cataract surgery. A comparative study of two modes of anaesthesia.
Trial report in International ophthalmology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
The objective of this study was to compare the light sensitivity and pain experienced by patients undergoing cataract surgery under subtenon and topical with intracameral anaesthesia. Fifty-four patients were randomly assigned to receive either two drops of proxymethacaine 0.5% as topical anaesthesia with 0.5 ml preservative-free 1% intracameral lidocaine or 4 ml 2% lignocaine as subtenon anaesthesia. Light sensitivity and overall pain perception were recorded at the end of surgery. The mean pain score in the subtenon group (0.11; range 0-1) was lower than in the topical group (1.07; range: 0-3, P < 0.001). The mean light-sensitivity score was lower in the subtenon group (0.26; range: 0-4) than in the topical group (1.29; range: 0-4, P = 0.001). Subtenon anaesthesia was more effective in suppressing light sensitivity and pain during cataract surgery than topical with intracameral anaesthesia. This suggests that use of subtenon anaesthesia may lead to a more comfortable operative experience.
