Effectiveness of Topical Anesthesia in Patients Undergoing Phacoemulsification Cataract Surgery versus Femtosecond Laser-Assisted Cataract Surgery.

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 assess the effectiveness of topical anesthesia in patients undergoing phacoemulsification cataract surgery (PCS) and femtosecond laser-assisted cataract surgery (FLACS), and investigate an efficient anesthesia protocol for FLACS. Methods: Non-randomized, prospective cohort study. In this study, patients undergoing cataract surgery self-selected their preferred technique (PCS or FLACS; n = 100 eyes per cohort) and received three topical anesthesia applications prior to phacoemulsification. Those opting for FLACS were randomized to receive the laser phase using either the Catalys (Johnson and Johnson Vision) or LenSx (Alcon Laboratories, Inc.) system, with one topical anesthesia administration before the laser step and two prior to phacoemulsification. Outcome measures included visual analogue scale pain scores, total surgical, anesthesia, and phacoemulsification durations, and anesthesia efficacy. Results: There was no significant difference in pain perception between the PCS and FLACS groups ( Conclusion: Both PCS and FLACS appeared safe and comfortable under topical anesthesia in this selected cohort. A single application of topical anesthesia was sufficient for the laser step in most FLACS patients, and the protocol of administering additional anesthesia between steps may offer a feasible strategy for workflow optimization. Anesthetic efficacy did not differ between the Catalys and LenSx systems, despite their different patient interface docking mechanisms.
