Factors Affecting Visual Outcome after Small Incision Lenticule Extraction (SMILE) Pro.
Article in Korean journal of ophthalmology : KJO, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo report the factors affecting visual outcomes after small incision lenticule extraction (SMILE) in eyes treated with the Visumax 800.
methodsThis is a retrospective study with cross-sectional design of eyes underwent SMILE Pro using Visumax 800 at Jakarta Eye Center. Patients ≤40 years old with a corrected distance visual acuity of >20 / 25, manifest refractive spherical equivalent ≤10.0 diopters (D), and cylinder refraction <5.0 D were included. Evaluation of visual outcomes was conducted at 1 day and 1 month postoperatively.
resultsA total of 258 eyes from 132 patients were analyzed. Among the total, 94% achieved an uncorrected distance visual acuity (UDVA) of 20 / 20 at 1 month postoperatively. Of the eyes with high myopia, 81% achieved a UDVA of 20 / 20, followed by 97% and 99% in moderate and low myopic eyes, respectively. Spherical equivalent refraction (r = 0.273, p < 0.01), optic zone (OZ; r = 0.260, p < 0.01), cap thickness (r = 0.209, p < 0.01), and residual stromal thickness (RST; r = 0.256, p < 0.01) showed a significant but weak correlation with UDVA at 1 month postoperatively. There is increasing risk to get <20 / 20 UDVA in right eyes (odds ratio [OR], 3.101; p < 0.045), eyes with high myopia (OR, 9.964; p < 0.01), 100-μm cap thickness (OR, 4.578; p < 0.01), ≤6 mm OZ (OR, 10.556; p < 0.01), and <300-μm RST (OR, 9.100; p < 0.01) at 1 month postoperatively.
conclusionsSMILE Pro results in promising visual outcome in early postoperative period. Patients with low to moderate myopia have better visual outcomes than those with high myopia. A small OZ, thin cap thickness, and low RST could increase the risk of not achieving the maximum visual outcome after SMILE. A prospective study with a longer follow-up period that includes comprehensive variables is needed to fully understand the factors affecting visual acuity after SMILE.
