PURPOSE: To evaluate whether autorefractometry values after implantation of diffractive multifocal intraocular lenses (IOLs) correlate with manifest refraction values. SETTING: Tokyo Dental College Suidobashi Hospital, Tokyo, Japan. METHODS: This retrospective study evaluated eyes that had cataract surgery with implantation of a diffractive multifocal IOL. One month or more postoperatively, the autorefraction values were compared with the manifest refraction values to determine the correlation between the 2 methods in sphere, cylinder, and spherical equivalent (SE). RESULTS: The study evaluated 156 eyes of 84 patients. The mean spherical refraction was 0.13 diopters (D) +/- 0.66 by autorefraction and 0.26 +/- 0.50 D by manifest refraction. The mean cylinder value was 0.94 +/- 0.58 D and 0.61 +/- 0.48 D, respectively. The mean SE was -0.34 +/- 0.66 D and -0.06 +/- 0.48 D, respectively. All 3 measurements by autorefraction and manifest refraction were well correlated (r(2) = 0.67, 0.66, 0.64, respectively). CONCLUSION: Findings show that postoperative autorefraction can be used to estimate the manifest refraction in eyes with diffractive multifocal IOLs.
