title: [Intraoperative Measurement of Refraction with a Hand-Held Autorefractometer].
abstract: OBJECTIVE
  The aim of this study was to evaluate an intraoperative measurement of objective refraction with a hand-held retinomax instrument.
  
  
  METHODS
  At the end of cataract surgery objective refraction in a lying position was measured with a retinomax instrument. On the first postoperative day the same measurement was performed with a retinomax and a standard autorefractometer. To evaluate the differences between measurements, the spherical equivalent (SE) and Jackson's cross cylinder at 0° (J0) and 45° (J45) was used.
  
  
  RESULTS
  103 eyes were included. 95 of them had normal cataract surgery. Differences between retinomax at the operative day and the standard autorefractometer were 0.68 ± 2.58 D in SE, 0.05 ± 1.4D in J0 and 0.05 ± 1.4D in J45. There were no statistically significant differences between the groups.
  
  
  CONCLUSIONS
  Intraoperative measurement of the refraction with a retinomax can predict the postoperative refraction. Nevertheless, in a few patients great differences may occur.
