The Engineer
A new circular cutting tool will make cataract surgery an easier process for doctors, according to its developers. The device from Warwickshire-based Warwick Design uses a circular superelastic nickel-titanium blade to cut an opening in the anterior of the capsule, a cellophane-like part of the eye that retains the failing lens. Current blades require surgeons to tear a circular hole, a skilled procedure that can lead to serious consequences if performed incorrectly.
