Gen 1 was used because Gen 2 was not available at the time of the study. However, Gen 1 can still be a good reference.Methods: Thirty-two consecutive eyes were included in this prospective nonrandomized study. ORange was used after phacoemulsification and intraocular lens implantation. There were no complications and no withdrawals from the study. The refraction data from the ORange were recorded in spherical equivalents and put into Excel. One week postoperatively, autorefraction was done and the data were again recorded in spherical equivalents and put into Excel. Both sets of data were then transferred to SPSS for a correlation study. Because ORange is an objective refractor, it is necessary to use another objective refractor, such as the Zeiss Autorefractor, for comparison. Measurement at 1 week postoperatively is for cornea clearance for autorefraction and is the closest time to intraoperative assessment for comparison.Results: The Pearson correlation was r = +0.56, P < 0.01, which qualifies for a moderate or good correlation (0.5–0.75).Conclusion: Intraoperative refraction using the ORange Gen 1 after cataract surgery and intraocular lens implantation is moderate to good when correlated with objective autorefraction 1 week after cataract surgery.Keywords: cataract surgery, intraocular lens implantation, refraction, autorefraction, intraoperative wavefront aberrometer  Ming ChenDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2011, Iss default, Pp 197-199 (2011)
