Purpose: To evaluate near, intermediate, and distant vision, optical quality, and patient satisfaction with Acri.LISA aspheric diffractive multifocal IOL.
Methods: Forty eyes of 20 patients received phacoemulsification and implantation of Acri.LISA IOL. Visual acuity was measured postoperatively at 1 week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function via questionnaire were measured at postoperative 1 month.
Results: Uncorrected near, intermediate, and distanct visual acuity at 1 month were 0.09 ± 0.14, 0.29 ± 0.17 and 0.11 ± 0.12, respectively. At 6 months, similar visual acuity results were measured. Total and higher-order wavefront aberration values were 0.66 ± 0.29 and 0.24 ± 0.08, respectively. Photopic contrast sensitivity at 1.5, 3, 6, 12, and 18 cycles/degree were 1.38 ± 0.32, 1.73 ± 0.24, 1.75 ± 0.21, 1.33 ± 0.18, and 0.77 ± 23, respectively, and mesopic contrast sensitivity values were 1.37 ± 0.27, 1.72 ± 0.16, 1.63 ± 0.14, 1.01 ± 0.19, and 0.50 ± 0.22. Total subjective visual function score was 3,127 ± 354, near work was 244 ± 36, distance work was 256 ± 21, and night driving was 221 ± 42.
Conclusions: The Acri.LISA 366D multifocal IOL can be effective for improving patient satisfaction after cataract surgery as well as for presbyopia correction.
