Purpose To asses visual quality after bilateral implantation of the Acri.LISA 366D intraocular lens (IOL) (Carl Zeiss Meditec) in patients with high and low–moderate myopia. Methods A total of 304 eyes of 152 patients had bilateral implantation of the Acri.LISA 366D IOL. The patients were divided into 2 groups: low–moderate myopia (IOL power from 15 to 20.5 D) and high myopia (IOL power from 0 to 14.5 D). Monocular and binocular best-corrected distance visual acuity (BCVA) and best distance-corrected near visual acuity (BCNVA), binocular best distance-corrected intermediate visual acuity (BCIVA), and distance contrast sensitivity (OS) under photopic (85 cd/m2) 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 BCVA (p=0.13 and p=0.22, respectively). Monocular and binocular BCNVA was comparable between the groups (p=0.26 and p=0.09, respectively). The mean binocular BCIVA changed significantly as a function of the distance of the test (p<0.01) in both groups, and there were no statistically significant differences between groups at any distance. Monocular and binocular CS under photopic and mesopic conditions was similar between both groups (p>0.01). Conclusions Bilateral implantation of the Acri.LISA 366D in high myopic eyes provides a satisfactory full range of vision comparable to that obtained in low–moderate myopic eyes.
