Comparing immersion ultrasound with partial coherence interferometry for intraocular lens power calculation.

Background And Objective: To compare the utility and accuracy of high-precision immersion ultrasound, partial coherence interferometry, and the IOL Master system (Carl Zeiss Meditec, Dublin, CA) in a tertiary care referral center.

Patients And Methods: Comparative clinical study in a tertiary care, multispecialty, university practice. Participants were consecutive patients scheduled for cataract surgery at Emory Eye Center.

Culture plate temperature and delayed incubation effect on bacterial recovery.

Purpose: To discover if initial culturing conditions (plate temperature and time delay to incubation) adversely influence the recovery of organisms associated with bacterial keratitis.

Methods: The rate of temperature equilibration of culture plates taken from a refrigerator and placed in an incubator and left on the desk was evaluated with a digital thermometer. A standard inoculum for each of five organisms (S.

A new, non-contact wide field viewing system for vitreous surgery.

Purpose: To report a new, noncontact wide field viewing system for vitreoretinal surgery.

Design: Device description: A noncontact wide field viewing system consisting of adjustable hinged arm and a combined condensing lens and reinverting prism has been developed. The arm clamps onto the operating table or wrist rest and holds the lens system in the air above the eye.
