Manual versus Markerless (Image-guided System) Toric Intraocular Lens Implantation Outcomes for Astigmatic Correction in Cataract Surgeries.

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
Objective: Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction. Methods: The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed. Results: A total of 70 patients were included in the study. Results showed no significant difference in the following characteristics between manual and markerless method at one month and two months post-cataract surgery: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near vision acuity (UNVA), corrected near vision acuity (CNVA), refraction spherical equivalent. The UDVA, CDVA, UNVA, CNVA and astigmatism had significantly lower median/mean-rank at one and two months postoperatively compared to pre-operative values. Conclusion: In conclusion, our findings indicated that both manual-based and markerless systems effectively facilitated accurate placement of the toric IOL on the desired axis. Notably, there was no significant difference observed between the two methods. Both systems are straightforward to execute. In low-resource settings like the Philippines, the manual marking method can be employed when markerless guidance equipment is unavailable.
