PURPOSE: To investigate a potential influence of @entity735 drops on wavefront sensing with the Zywave aberrometer (Technolas Perfect Vision) in terms of @entity2516 ( @entity2516 ) and @entity2008 ( @entity2008 ). METHODS: In this prospective study, 200 @entity735 were measured in miosis and pharmacologically induced @entity5564 with an aberrometer and automated refraction. One @entity735 were dilated with @entity12023 0.5%+ @entity2647 2.5% eye drops ( @entity12023 / @entity2647 group), and the remaining 100 eyes with @entity12023 0.5% ( @entity12023 only group). The @entity2516 values for a pupil diameter of 3.5 mm in miosis and @entity5564 , respectively, were compared and correlated to the corresponding values of automated refraction. Changes in HOAs up to the 4th order were recorded. RESULTS: Predicted phoropter refraction values obtained in @entity5564 were less myopic than in miosis. The spherical equivalent refraction of @entity2516 differed by an average of 0.36    0.36 diopters (D) in the @entity12023 / @entity2647 group. In the @entity12023 only group, the difference was 0.24    0.43 D. Sphere of @entity2516 differed by an average of 0.33    0.36 D in the @entity12023 / @entity2647 group and by an average of 0.24    0.35 D in the @entity12023 only group. @entity1 age had no major influence on the level of difference. Automated refraction yielded a smaller difference in spherical equivalent refraction. Changes in @entity2008 root-mean-square were statistically significant. CONCLUSIONS: The cycloplegic effect of @entity735 drops should be taken into account when interpreting aberration measurements and planning a wavefront-guided ablation. Ideally, the use of @entity735 drops should be avoided to minimize refractive surprises.
