Effect of Capsular Tension Ring on Refractive and Morphological Outcomes in Pseudoexfoliative Eyes.

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 effect on anterior chamber depth (ACD) and postoperative refractive prediction error (PE) of capsular tension ring (CTR) implantation during phacoemulsification in pseudoexfoliative (PEX) eyes. Methods: Prospective case-control study of eyes submitted to uneventful cataract surgery, divided into three study groups: Group 1 - controls; Group 2 - PEX eyes without CTR implantation; Group 3 - PEX eyes with CTR implantation. Biometric data including ACD were measured preoperatively and 1-month postoperatively, using swept-source anterior segment optical coherence tomography (ANTERION Results: A total of 25 eyes were included in each group. Anterior chamber increased significantly in all groups (p<0.001), with the change being significantly greater in Group 2 compared to Group 1 (p=0.014). No significant differences in ACD changes were observed between Group 3 and the other groups (p>0.05). In Group 2, a significant hyperopic shift (p=0.035) and 12% of eyes with a prediction error above 1D was observed, which were not seen in Groups 1 or 3. The percentage of eyes with a PE within ±0.25D was significantly lower in Group 2 (p=0.013). IOP and ECD decreased similarly across all groups (p>0.05). Conclusion: Routine CTR implantation during uneventful phacoemulsification in PEX eyes appears to prevent the pseudoexfoliative hyperopic shift previously reported, likely due to more even zonular tension distribution. If CTR is not used, a slightly myopic target should be considered.
