Bilateral implantation of the Acri.LISA bifocal intraocular lens in myopic eyes.
OBJECTIVE
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 (CS) 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.
