PURPOSE: The intra- and postoperative characteristics of two foldable single-piece intraocular lenses (IOL) with identical hydrophilic acrylic material, but different haptic designs (Akreos Adapt and Akreos Fit), were compared in combined phacoemulsification and pars plana vitrectomy (PPV). METHODS: This was a prospective, randomized study in patients with simultaneous cataract and vitreoretinal surgery. Group A (n=47 patients) included implantation of Akreos Fit IOL (two-point haptic) and group B (n=46 patients) implantation of Akreos Adapt IOL (four-point haptic). All intraoperative modifications of small-incision phacoemulsification and three-port PPV and IOL implantation and centration were documented. At 1 and 2 days and 6 months after surgery, best-corrected visual acuity (BCVA), slit-lamp appearance (including inflammation, IOL centration, capsulorhexis diameter, posterior capsule opacification (PCO), tonometry, and fundus findings were evaluated. RESULTS: The groups did not differ with respect to age, surgical indications and modifications, intraoperative IOL handling, and centration. At day 2, inflammation and capsulorhexis diameters were similar, but IOL decentration was slightly more frequent with Akreos-Fit IOLs. Six months after surgery, the rates of PCO, posterior synechiae, and BCVA were similar. Akreos-Fit had slightly smaller capsulorhexis diameters and slightly more capsular contraction and IOL decentration (P>0.05). CONCLUSIONS: Both of the Akreos IOL are feasible for combined phacoemulsification and PPV. Although similar in intraoperative handling, BCVA, and PCO, IOL centration was slightly better with Akreos-Adapt than with Akreos-Fit after combined surgery.
