Purpose To demonstrate the use and potential for two very disparate measures of glare and dysphotopsia Methods We report the development of a system of measuring pseudophakic dysphotopsia dependent on patient recognition of photographic plates. The photographs are structured such that type and intensity of varied dysphotopsia can be assessed. The photographs have been used in preliminary studies to assess prevalence of dysphotopsia and also to compare the amount in patients with different intraocular lenses. In a parallel study C‐Quant measures of stray light were obtained on 106 patients referred to the cataract clinics. In addition to tests of visual acuity and contrast sensitivity (LogMar and Pelli‐Robson), cataract morphology was assessed using the Oxford cataract grading system. The paper examines associations and differences between the visual and clinical measures and using latent class analysis explores subgroups of different patient profiles
