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

purposeTo assess the biometry and postoperative refraction in iris repair using ArtificialIris in combination with an intraocular lens (IOL).

settingDepartment of Ophthalmology, University Hospital Heidelberg, University of Heidelberg, Germany.

designRetrospective observational study.

methodsWe included 44 aniridic and aphakic eyes for IOL implantation in combination with iris prosthesis reconstruction. The iris prostheses were either sutured into the ciliary sulcus and fixed by transscleral suturing or were implanted together with a capsular tension ring and the IOL in the capsular bag. The primary outcomes measured were pre- and postoperative best corrected visual acuity (CDVA), objective and subjective refraction, anterior chamber depth and optical biometry comparing common IOL formulae.

resultsReasons for surgery were trauma (39 eyes), iatrogenic causes (1 eye), aniridic state after severe iritis (2 eyes) or iris tumor (2 eyes). Monocular CDVA improved significantly (p<0.0001) from median 0.55 logMAR (0.0 to 1.98) to 0.16 logMAR (-0.08 to 2.0). There were no significant differences between the postoperative target refraction calculated by the formulae "Haigis", "Hoffer-Q", "SRK/T" and "Holladay 1" (p=0.68). The absolute deviation from target refraction did not differ significantly between the formulae (p=0.87). Median target refraction was -0.42 D (-4.0 to 1.68). Postoperatively median spherical equivalent was 0.00 D (-5.38 to 2.38). Median absolute deviation from target refraction after 5 months of follow-up was 0.98 D (0.06 to 5.17).

conclusionPostoperative refraction using common techniques and using preoperative biometry revealed a well predictable postoperative refraction. There is no correction factor needed.
