Limitations and notes

Abstract-reviewed, single-center study. Enrolled counts are 400 patients and 800 eyes; endpoint denominators and attrition were not independently specified in the abstract, so they remain unstructured. The overlapping high-cylinder subgroup is not a separate additive arm.

Missing fields are not interpreted as negative findings. Arm counts may not be additive in all study designs.

Study evidence level
A simple, non-GRADE hierarchy based on design: randomized and large regulatory trials are high; prospective cohorts moderate; retrospective observational studies low. Manual review can override this label.
