Comparative Analysis of Effective Lens Position and Refractive Outcomes in Scleral-Fixated versus Intracapsular Intraocular Lenses.
Article in Clinical ophthalmology (Auckland, N.Z.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
Purpose: To evaluate the outcomes of scleral-fixated intraocular lenses (IOLs) implanted using either Yamane technique or Gore-Tex suture fixation, in comparison to intracapsular lens fixation, and to assess the efficacy of various lens formulas in achieving predicted refractive targets. Patients and Methods: This study included 45 eyes from 44 patients with scleral-fixated IOLs, comprising 37 Yamane eyes and 8 Gore-Tex eyes. Preoperative refractive predictions from various formulae were compared with final postoperative refraction. Outcomes assessed included effective lens position (ELP), postoperative predictive error, and changes in visual acuity. The ELP of scleral-fixated IOLs was compared with that of intracapsular IOLs in fellow eyes. Results: Average ELP for Yamane IOLs was 0.62 mm more posterior relative to intracapsular IOLs but was not significantly different for Gore-Tex IOLs. Average postoperative logMAR acuity change was significant at -1.30 (p=4.5x10 Conclusion: Different scleral fixation techniques result in variations in ELP compared to intracapsular IOL placement. In our hands, when using the Yamane technique, surgeons should aim for a myopic refractive target to offset hyperopic errors when employing the Barrett Universal II, Hill-RBF, or Hoffer QST formulas, and a hyperopic target when using the Holladay formula. For Gore-Tex IOLs, a slightly hyperopic target is recommended to counter myopic error when using the Barrett Universal II formula, whereas a slightly myopic target is advised with the Holladay formula to offset hyperopic error. A limitation of our study is the small sample size for patients who underwent Gore-Tex suture fixation.
