Autorefraction after implantation of diffractive multifocal intraocular lenses.
OBJECTIVE
To evaluate whether autorefractometry values after implantation of diffractive multifocal intraocular lenses (IOLs) correlate with manifest refraction values.


METHODS
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).


CONCLUSIONS
Findings show that postoperative autorefraction can be used to estimate the manifest refraction in eyes with diffractive multifocal IOLs.
