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 report a case of diffuse intraocular lens (IOL) opacification in a patient who started complaining of blurred vision in his left eye over the course of three years after having phacoemulsification surgery combined with capsular bag fixation of a C-flex 570C IOL. The IOL had been repositioned in the ciliary sulcus following its subluxation.

methodAn IOL exchange was performed, and the explanted IOL was sent for histopathological analysis.

resultsScanning electron microscopy identified multiple crystalline-like deposits on both sides of the IOL. The optic was more extensively involved than the haptics. Energy-dispersive X-ray spectroscopy confirmed the predominance of calcium within the deposits.

conclusionsThe breakdown of the blood-aqueous barrier seems to be a key component of this calcification process. Ciliary sulcus fixation is not a suitable option for C-flex 570C IOLs.
