B Hex Pupil Expander

This surgical video, presented by Dr Ohoud Owaidhah a glaucoma consultant at King Khaled Eye Specialist Hospital, presents the initial experience at KKESH with the B-Hex pupil expansion device in a case of pseudoexfoliation glaucoma and cataract undergoing combined phacoemulsification with trabeculectomy. The B-HEX® Pupil Expander (Med Invent Devices) is a disposable 6.5 mm flexible hexagonal device with notches at corners and flanges at sides. Alternate flanges with positioning holes are tucked under the iris to engage the notches to the margin of the pupil to provide a 5.5 mm expanded pupil. The preloaded B-HEX is inserted and removed through a 1 mm or larger incision using a manipulator or 23-gauge micro-forceps. The thin profile and uniplanar design allow unhindered instrument movement during phacoemulsification, cortical cleaning, and intraocular lens implantation. The B-HEX is safely used even after capsulorhexis since the thin uniplanar notches are directly visualized to avoid the capsule margin.
