Long-term follow-up of SMILE-derived corneal stromal lenticules preserved in nutrient capsules for treating corneal diseases.
Observational study in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 investigate the long-term safety and efficacy of using keratorefractive lenticule extraction (KLEx)-derived corneal stromal lenticules preserved in nutrient capsules for the treatment of corneal diseases.
settingEye and ENT Hospital of Fudan University.
designObservational study.
methodsTen eyes of 10 patients with corneal diseases (6 males, 4 females, age 38.10 ± 9.11 years, ) were treated with phototherapeutic keratectomy combined with epikeratophakia or intrastromal keratoplasty using KLEx-derived lenticules. Corneal stromal lenticules which used for transplantation was extracted from healthy myopia patients and stored in nutrient capsules at 4 °C for 28 days. Patients underwent slit-lamp microscopy, uncorrected and corrected distance visual acuity (CDVA), subjective refraction, corneal topography, and anterior segment optical coherence tomography evaluations preoperative and were followed-up at 1-week, 1-month, 3-months, and 1-year postoperatively.
resultsNo complications occurred intra- or postoperatively. CDVA increased by at least two lines in seven eyes and by one line in one eye, while remaining unchanged in two eyes, by the final follow-up. There was no significant difference found in the comparison of each postoperative corneal thickness to preoperative measure. The lenticules maintained a good degree of transparency 1-year post-operatively and adhered closely to the adjacent tissue. Intraocular pressure remained stable from preoperatively to all points postoperatively. There was no significant difference in corneal endothelial cell density values between pre and all post-operative time points.
conclusionKLEx-derived corneal stromal lenticules preserved in nutrient capsules for up to 28 days can be safely and effectively utilized as allografts for the treatment of corneal diseases, demonstrating favorable long-term outcomes.
