Autorefraction after implantation of diffractive multifocal intraocular lenses.

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.
