A preliminary investigation into the direct measurement of intra‐ocular light scatter after radial keratotomy

A glare score based on intra‐ocular light scatter and a questionnaire‐based subjective assessment of glare were determined for 18 patients who had undergone radial keratotomy (RK) two weeks to 27 months previously. Results were compared to those of 15 control subjects. T‐tests showed no significant difference in glare experienced under photopic conditions by RK patients and control subjects. There was no systematic relationship between glare scores and the subjective assessment of glare, nor between glare scores or subjective assessment of glare and the time which had elapsed since surgery. However, a weak relationship (r2=0.36) was found between glare scores and absolute refractive error. It was concluded that RK did not produce significant levels of intra‐ocular light scatter under photopic conditions (155 lux).
