Abstract Details

Purpose:

To assess the validity of automated-refraction (AR) for estimating the manifest refraction (MR) in patients implanted with a trifocal intraocular lens (IOL).

Setting:

Clínica Rementería, Madrid, Spain

Methods:

The study included patients having bilateral implantation of the AcrySof® IQ PanOptixTM IOL.  The IOL power calculation was made in order to obtain emmetropia in all patients. Three month after the surgery patients underwent a complete MR. In all cases, AR was performed as the starting point for obtaining the final MR. For the analysis, sphere and cylinder values were considered and both AR and MR sphero-cylindrical values were expressed in the three power vectors: M (spherical equivalent), J0 and J45

Results:

This study analyzed 62 eyes of 62 patients. After the surgery the mean sphere was 0.07 ± 0.34D for AR and 0.06 ± 0.02 for MR (p=0.38); the mean cylinder was -0.60 ± 0.36D for AR and -0.17 ± 0.38D for MR (p<0.001); mean M was: -0.23 ± 0.31D for AR and -0.03 ± 0.14D for MR (p<0.001); mean J0 was 0.21 ± 0.17D for AR and 0.07 ± 0.17D for MR (p<0.001) and mean J45 was 0.07 ± 0.17D for AR and -0.02 ± 0.11D for RM (p<0.001).

Conclusions:

The results of this study suggest that patients implanted with this trifocal IOL considered show AR results with a trend to a more negative amount of cylinder of about -0.50D, while the other parameters showed no clinical significant differences between AR and MR.
