Abstract:
1. A sterile barrier for use with a slit lamp, the slit lamp having a proximal handle and a distal light slit transmitting window, the sterile barrier comprising: a flexible tubular membrane having a distal first end, a proximal second end, and an opening therebetween, the opening extending through the first end; a resilient band attached to the first end of the tubular membrane so that an opening of the resilient band is substantially coextensive with the opening adjacent the first end, the resilient band having a relaxed configuration and a resiliently expanded configuration; the opening adjacent the first end and the resilient band in the resiliently expanded configuration being sufficiently large to receive the handle proximally therethrough; the opening adjacent the first end, when the resilient band is in the relaxed configuration, being as small as or smaller than a cross-section of the slit lamp between the handle and the window so that the band will releasably restrain the sterile barrier from moving proximally off the handle.
