Evaluation of two techniques for irrigation/aspiration retrolental viscoelastic removal in cataract surgery

Purpose: To compare surgical results after phacoemulsification using two different techniques for removal of Ophthalmic Viscoelastic Device (OVD). Methods: A randomized prospective study was conducted on 77 patients who underwent cataract surgery. In the first group, OVD was removed over the optic by small abrupt horizontal and vertical displacements of the IOL. In the second group OVD was removed by placing the I/A probe behind the IOL. Intraocular Pressure (IOP), Intraocular Lens Position (IOLP) and refraction were analyzed over the first six weeks.
