The Pocket Strabismus Surgical Skills Trainer: design and validation.
Article in Journal of AAPOS : the official publication of the American Association for Pediatric Ophthalmology and Strabismus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSynthetic models for strabismus surgery have the potential to enhance training without the complexities of biologic material. Models described to date are relatively large and costly, potentially limiting access. We set out to design and validate a handheld surgical strabismus trainer.
methodsUtilizing a silicone mold and 3D printer, we developed a 6.25 × 4.5 × 2.5 cm model, the "Pocket Strabismus Surgical Skills Trainer," optimized for practicing essential steps of strabismus surgery, including securing the muscle, scleral passes, and conjunctival closure. The materials required to print each model cost less than US $30. We surveyed participants across three ophthalmology training programs who participated in two workshops. Perceptions were assessed with an anonymous Likert scale questionnaire.
resultsThirty trainees and 6 faculty completed the survey. All participants reported that the pocket simulator had easy open/close, setup, and storage (P = 0.003). The appearance of the eyeball, sclera, and rectus muscles was felt to be sufficiently reproduced among the majority of participants (97%, 86%, and 81%, resp. [P = 0.001]). Most participants agreed that the sclera/extraocular muscles felt realistic (77%/81% [P = 0.005]) and modeled real practice (92%/100% [P = 0.002]).
conclusionsTrainee and faculty perceptions of the Pocket Strabismus Surgical Skills Trainer reflected ease of use, realistic critical ocular tissue structures, and a design that facilitates practice of key surgical steps. These results support our goal to provide a low-cost model that will broaden hands-on strabismus surgical training.
