| Background: Radial keratotomy is a major type of refractive surgery. This study was performed to determine the association of visual evoked potential (VEP) and radial keratotomy.
Materials and methods: In this cross-sectional descriptive-comparative survey, 25 patients under radial keratotomy attending to Basir Clinic in 2014 and 2015 were enrolled and the VEP results, including voltage and latency, were determined and compared with 25 control subjects.
Results: The mean voltage was 5.6 ± 2.0 microvolt and 6.0 ± 2.2 microvolt in case and control groups, respectively (P>0.05). Mean latency duration was 95.7 ± 6.1 millisecond and 95.6 ± 5.7 millisecond in case and control groups, respectively (P>0.05).
Conclusion: Totally, according to the obtained results, it may be concluded that there is no significant association between visual evoked potential and radial keratotomy.
