The Eye

The aftermath of an eye surgery can often be a painful one -- possible infections loom, as well as blurred vision and inflammation. I-Therapeutix, based in Waltham, Massachusetts, developed the I-ZIP bandage, a hydrogel coating that offers a suture-free method for healing cataract incisions. The company, which closed a $15 million round of venture capital in June, also hopes to aid glaucoma patients by creating gel-like eyelid inserts that will administer medication automatically.
