Purpose: To assess the visual quality after bilateral implantation of the Acri.LISA 366D intraocular lens (IOL; Carl Zeiss Meditec, Jena, Germany) in patients with hyperopia.
Design: Prospective, nonrandomized study.
Methods: One hundred and seventy eyes of 85 patients had bilateral implantation of the Acri.LISA 366D IOL. The patients were divided into 2 groups: low to moderate hyperopia (IOL power, 21 to 24.5 diopters [D]) and high hyperopia (IOL power, 25 to 36 D). Monocular and binocular best spectacle-corrected visual acuity (BSCVA), best distance-corrected near visual acuity (BCNVA), binocular best distance-corrected intermediate visual acuity (VA), and distance contrast sensitivity (CSF) under photopic (85 cd/m(2)) and mesopic (5 cd/m2) conditions were determined.
Results: At the 6-month postoperative visit, there were no statistically significant differences in monocular and binocular BSCVA (P = .06 and P = .09, respectively). Monocular and binocular BCNVA were comparable between both groups (P = .24 and P = .42, respectively). The mean binocular best distance-corrected intermediate VA changed significantly as a function of the distance of the test (P < .01) in both groups, and there were no statistically significant differences between groups at any distance. Differences were not found between groups in binocular CSF under mesopic and photopic conditions.
Conclusions: Bilateral implantation of the Acri.LISA 366D in patients with high hyperopia provided a satisfactory full-range of vision comparable with that obtained in patients with low to moderate hyperopia.
