Abstract
This ophthalmological instrument is intended to aid in the removal of the mount (lens haptic) of an artificial intraocular lens from the eye, allowing the portion of the mount located behind the iris to be captured and severed by means of an axially sliding cutter installed inside the instrument head, in a tubular guide. In order to capture, sever and remove the mount from the eye in one single operation, it is the intent for the tubular guide to have a lateral opening at its tip, which is closed off by a stop plate at its face end. Parallel with the cutter, a holder with axially sliding motion is supported inside the tubular guide, which may be moved to contact the stop plate, independent of the cutter. The loop end to be severed is inserted sideways into the opening and, initially, clamped down by the holder against the stop plate, only to be severed by the cutter. Subsequently, the severed loop end is removed from the eye while still clamped down by the holder.
