Comparative analysis of myopia correction outcomes and aberration changes between PRK and SMILE: A study based on strict refractive criteria.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 analyze the refractive outcomes and changes in corneal aberrations after PRK and SMILE surgeries, and to compare these two methods. PATIENTS AND
methodsThis retrospective comparative study investigated patients aged 20-40 years who underwent SMILE or PRK for the correction of myopia between - 1.00 D and - 2.00 D, along with a cylindrical power of -0.50 D or lower. Preoperative and 6-month postoperative assessments included uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and corneal aberrations such as higher-order aberrations (HOA), spherical aberrations (SA), vertical coma (Z3,-1), horizontal coma (Z3,1), oblique trefoil (Z3,-3), and horizontal trefoil (Z3,3).
resultsA total of 73 eyes from 73 patients (37 SMILE and 36 PRK) were analysed. Both groups showed significant improvement in UCVA and refractive parameters (p < 0.05), while BCVA remained stable (p > 0.05). Postoperative corneal aberrations increased in both groups, with no significant intergroup differences (p > 0.05).
conclusionsBoth SMILE and PRK are effective and safe for the correction of low myopia, with comparable refractive outcomes and visual quality. Despite an increase in corneal aberrations in both techniques, their impact on overall visual performance is similar. Procedure selection should be individualized based on patient-specific factors and lifestyle.
