Abstract

ABSTRACT: Purpose : To assess the decentration and tilt of one-piece foldable acrylic intraocular lens following two different intraocular lens implantation techniques. Methods : This prospective, randomized clinical study conducted on 102 eyes of 91 patients who underwent cataract surgery between September 2015 and May 2016 at Ulucanlar Eye Training and Research Hospital, Ankara, Turkey. Intraocular lens implantations were performed with the help of an ophthalmic viscosurgical device or a hydroimplantation technique during surgery. The main outcomes, which were evaluated one day and one month after surgery, were corrected distant visual acuity, intraocular lens tilt, and decentration at the vertical and horizontal meridians. All outcomes were compared between and within implantation technique groups. Results : Angle of tilt and decentration of intraocular lens at the vertical and horizontal meridians showed no significant change within the ophthalmic viscosurgical device and hydroimplantation groups during follow-up ( p > 0.05 for all). However, intraocular lens at both meridians were significantly lower in the hydroimplantation group (Vertical: p = 0.004, Horizontal: p = 0.015), and intraocular lens decentration tilt at both meridians were significantly lower in the hydroimplantation group than in the ophthalmic viscosurgical device group (Vertical: p = 0.004, Horizontal: p = 0.039). Postoperative corrected distant visual acuity outcomes showed no difference between and within the groups during follow-up ( p > 0.05 for all). Conclusions : The intraocular lens implantation technique had an important effect on intraocular lens position. The hydroimplantation technique induces central placement of one-piece foldable acrylic intraocular lenses postoperatively by reducing decentration and the angle of tilt.
