Abstract Details

Purpose:

To evaluate whether autorefractometry values after implantation of a bioanalogic, polyfocal, intraocular lens (WIOL-CF; Medicem) correlate with manifest refraction values. This information is important mainly for post-operative follow up of patients where autorefractometers are widely used.

Setting:

Department of Ophthalmology, University Hospital Kralovske Vinohrady and 3rd Medical Faculty Prague, Czech Republic.

Methods:

Eyes that underwent cataract surgery with implantation of a bioanalogic, polyfocal IOL were retrospectively evaluated in this study. Values from the autorefractometer (Nidek) were compared with the manifest refraction values to determine the correlation between the 2 methods. Spherical and cylindrical refractive errors were collected minimum one month after the surgery.

Results:

16 eyes of 8 patients were included in this study. The mean spherical refractive error was +3.57 ±1.649 diopters (D) measured by autorefractometer and -0.03±0.195 D in manifest refraction. The mean cylinder value was -1.69 ±0.93 D and 0.00 D, respectively. The mean SE was +2.72 ±1.29 D and -0.03 ±0.195D, respectively. No statistical correlation was found comparing measurements by autorefractometer and manifest refraction.

Conclusions:

The results show that postoperative values measured by autorefractometer cannot be used to estimate the manifest refraction in eyes with bioanalogic, polyfocal IOL.
