Review of intraocular lens power calculation formulas in eyes after corneal refractive surgery.
Review in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The correct post-operative refractive outcome is a crucial aspect of phacoemulsification. Mostly, it relies of effective lens position (ELP) estimation resulting from the selection of appropriate intraocular lens (IOL) power calculation formula. ELP estimation is especially difficult in eyes that have undergone corneal refractive surgery (CRS) since quandaries in achieving an accurate corneal power. It is caused by incorrect measurement of anterior corneal curvature, changes in posterior corneal curvature and aberration of corneal refractive index (1.375). At least several dozen IOL power calculation formulas in eyes with previous CRS have been developed to date. Seventeen the most used formulas were described, and their accuracy was evaluated in this study. The trueness of the formulas was assessed using the mean absolute error (MAE), median absolute error and percentage of eyes with prediction error within ± 0.5 D and ± 1.0 D. In the most studies, Barrett True-K obtained the smallest MAE in previously hyperopic eyes. In previously myopic eyes, Barrett True-K yielded accurate results also, but the Okulix and the Triple-S formulas performed equally well. Thus, Barrett True-K usually achieves the accurate outcomes in IOL power calculation in eyes that have undergone CRS. However, there is still no consensus on the formula choice in post-refractive eyes.
