Role of toric intraocular lenses in the correction of keratoconic eyes with cataract.

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
purposeTo investigate the optimal intraocular lens (IOL) corrections for virtual eyes with moderate to severe keratoconus (KC) using ray tracing and comparative analysis of image quality.
settingComputer simulations conducted using MATLAB-based custom ray-tracing software.
designThe study included 20 eyes generated from a statistical eye model called SyntEyes, which produces eye biometrics for KC eyes for optical simulation. The visual Strehl ratio (VSX) was used to quantify image quality based on optical wavefront analysis.
methodsThe eyes underwent various simulated corrections, including spherical and toric IOLs, as well as spherical and toric rigid gas-permeable (RGP) contact lenses, both individually and in combination. Comparisons were made across different correction strategies.
resultsSpherical and toric IOLs alone modestly improved VSX to 0.025 ± 0.004 and 0.034 ± 0.005, respectively, from a baseline of 0.013 ± 0.003 (P < .001). By contrast, eyes corrected with toric RGP lenses after IOL implantation demonstrated significantly higher image quality: 0.250 ± 0.014 (spherical IOL) and 0.246 ± 0.014 (toric IOL) (P < .001). However, combining 2 toric elements often led to overcorrection and increased aberrations.
conclusionsIOL corrections alone are insufficient to compensate for large corneal aberrations present in KC eyes. Subsequent fitting with toric RGP lenses can restore most eyes to normal levels of visual image quality. Among the compared IOL corrections, the combination of a spherical IOL with a toric IOL gave the best average VSX on average and avoids chances of overcorrection.
