An ophthalmological instrument for facilitating controlled insertion of an intraocular lens having resilient, open-loops into the posterior chamber of an eye includes a holder dimensioned for being held by a surgeon from which extends a loop-receiving member configured for receiving and deforming a first one of the loops from its normally nonstressed arcuate shape into a substantially straight and stressed condition. A displacement device associated with the loop-receiving member is selectively operable by the surgeon for displacing the first loop away from the loop-receiving member so that the stored energy in the loop imparts rotation to the lens as it is inserted into the posterior chamber of the eye.
