Abstract Details

Purpose:

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

Setting:

Clínica Rementería, Madrid, Spain

Methods:

The study included patients having bilateral implantation of the AcrySof® IQ PanOptixTM Toric 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 43 eyes of 43 patients. After the surgery the mean sphere was 0.17 ± 0.42D for AR and 0.03 ± 0.02 for RM (p=0.03); the mean cylinder was -0.49 ± 0.31D for AR and -0.05 ± 0.21D for RM (p<0.001), mean M was: -0.13 ± 0.40D for AR and 0.01 ± 0.12D for RM (p<0.001), mean J0 was 0.18 ± 0.16D for AR and 0.02 ± 0.10D for MR (p<0.001) and mean J45 was -0.04 ± 0.16D for AR and 0.00 ± 0.03D for RM (p<0.001).

Conclusions:

The results of this study suggest that patients implanted with the Panoptix toric 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
