1 · What the graph read from it

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.

2 · The registry

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

purposeWe investigated changes in corneal higher-order aberrations (HOAs) after iStent inject® W implantation combined with cataract surgery. STUDY

designRetrospective observational study.

methodsA total of 41 eyes that underwent this procedure between August 2022 and July 2024 were included. Intraocular pressure (IOP), corneal HOAs, coma-like aberrations, and spherical-like aberrations were measured before and at 1, 2, and 3 months after the surgery. A mixed-effects model was used for statistical analysis.

resultsMean IOP significantly decreased from 14.7 ± 2.9 mmHg before surgery to 13.5 ± 2.9 mmHg (P = 0.002) at 1 month, 13.0 ± 2.4 mmHg (P < 0.0001) at 2 months, and 12.9 ± 2.8 mmHg (P < 0.0001) at 3 months after surgery. The mean corneal HOAs was 0.221 ± 0.136 μm preoperatively, and this was not significantly different compared with those postoperatively (0.208 ± 0.100 μm at 1 month, 0.222 ± 0.134 μm at 2 months, and 0.236 ± 0.176 μm at 3 months postoperatively). Similarly, the mean coma-like aberration (0.205 ± 0.132 μm) and the mean spherical-like aberration (0.080 ± 0.043 μm) preoperatively did not significantly change postoperatively.

conclusionFollowing iStent inject W implantation IOP is reduced whereas, corneal HOAs remain stable for up to 3 months.
