Comparing Rotational Stability Over Time Between Four Monofocal Toric Intraocular Lenses.

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
Purpose: To evaluate the rotational stability of four different monofocal toric intraocular lenses (IOLs) from surgery to 4-6 months postoperative. Methods: This was a subset of data from a prospective multi-center randomized clinical study. High resolution retro-illuminated images of eyes implanted with four different toric IOLs were obtained immediately after surgery, and at 1 day, 1 week, 1 month and 4-6 months after surgery. Fixed scleral features were identified in the surgical image. An independent reading center evaluated the orientation of the IOL from all images, based on the angle between the toric axis marks and these fixed scleral landmarks. Rotational stability was determined by calculating differences in orientation between visits. Results: Digital images from 299 eyes implanted with one of the four IOLs were available for analysis. Orientation data were successfully determined in about 90% of images. Biometry and IOL orientation were not significantly associated with IOL rotation. The Vivinex lens showed the lowest absolute rotation, with a mean value less than 1.5 degrees at all time intervals measured, with a maximum standard deviation of 1.4 degrees. The AcrySof lens was next lowest, with an absolute rotation below two degrees for all intervals. Mean absolute rotation for the Tecnis lens was significantly higher than for the other IOLs (>2 degrees for all intervals). For the AcrySof and Vivinex lenses, there were no reported rotations >10 degrees for any interval; 97% or more of results were <5 degrees, compared to 93% for the AT Torbi lens and 90% for the Tecnis lens. Only 6 lenses (4 Tecnis: 8.3%, 2 AT Torbi: 4.3%) had a rotation > 10 degrees at any time point. Conclusion: Rotational stability appeared excellent for the Vivinex and AcrySof toric IOLs, with slightly more variable performance evident with the AT Torbi and Tecnis IOLs.
