Abstract

Purpose:

To report a novel technique for repurposing disposable wide-angle lenses used in vitreoretinal surgery for noncontact posterior segment examination.

Methods:

Clinical technique report with imaging.

Results:

The disposable lens for the noncontact BIOM viewing system manufactured by OCULUS Optikgerate GmbH (Wetzler, Germany) is a 100-diopter converging lens with wide-angle viewing ability. When appropriately processed after initial use, this lens is able to safely provide clinically useful viewing of the posterior segment when combined with a slit-lamp microscope, at a fraction of the cost of commercially available lenses.

Conclusion:

Repurposing used disposable lenses from a noncontact surgical viewing system provides an alternative means of posterior segment examination at a minimal cost. This technique could improve access to retinal evaluation and care in resource-poor settings.
