Abstract

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.

  Figure 3 Slit lamp biomicroscopy (A, B) and ultrasound biomicroscopy (C) 1 day after phacoemulsification. (A) There is a gap between the posterior capsule and IOL. Anterior shift of IOL is noted. (B) Full coverage of the optic with continuous curvilinear capsulorrhexis margin is shown. (C) Anterior bowing of the IOL and touch of the optic to iris margin is noted.

  Figure 4 Slit lamp biomicroscopy (A) and ultrasound biomicroscopy (B) 1 day after irrigation and aspiration of remnant OVD behind IOL. (A) The gap between the posterior capsule and IOL disappeared. (B) Anterior bowing of the IOL and touch of the optic to the iris margin disappeared showing the usual PCL location within the bag.
