Complications

No structured complication observations are available for this arm. This means “not reported in this dataset,” not zero complications.

Study design

Extended prospective follow-up of a noncomparative case series through seven years.

Limitations and notes

Clear lens extraction is represented under the RLE procedure. Forty-nine eyes contributed the seven-year retinal-detachment denominator.

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.
