    Intraoperative aberrometry can help improve refractive results

    Aphakic and pseudophakic readings both provide useful information

     

    Study results

    The mean refractive deviation between the intraoperative aphakic and intraoperative pseudophakic refractions was 0.21 ± 0.27 D, between the phakic and manifest refractions 0.21 ± 0.28 D, and between the pseudophakic and manifest refractions 0.18 ± 0.26 D, Dr. Wiley reported.

    The investigators found that the difference between the predicted postoperative spherical equivalent based on the aphakic measurement and the pseudophakic spherical equivalent measurement was 0.5 D or less in 84% of eyes.

    Regarding the refractive outliers, seven of the 50 eyes had a pseudophakic refraction that differed by more than 0.5 D from the aphakic refraction. In five (71%) of the seven eyes, the pseudophakic prediction was closer to the manifest refraction than the aphakic fraction.
