Novel device designed for pupil enlargement, stabilization in IFIS eyes
Novel device designed for pupil enlargement, stabilization in IFIS eyesWisconsin ophthalmologist Gerald P. Clarke, MD, has developed a new horseshoe-shaped dilator for use during cases of intraoperative floppy iris syndrome.
Redesigned pupil expansion device reduces cataract surgery risksPre-treatment with the femtosecond laser in eyes undergoing cataract surgery can induce miosis. The use of a pupil expansion device, however, offers an effective method for managing small pupils in femtosecond laser-assisted cases whether the problem pre-exists or is caused by the laser, said Boris Malyugin, MD, PhD.
Managing small pupils: A step-wise approachBoris Malyugin, MD, PhD, explains how he uses a step-wise approach to manage small pupils, starting with an intracameral injection of phenylephrine or epinephrine and eventually working up to pupil expanders.
