- Abstract
Purpose: To assess quality of vision by measuring ocular light scattering with two platforms and comparing them to traditional tests, in healthy subjects and cataract patients., Patients and Methods: One hundred and sixty-eight eyes divided in two groups were examined by the same clinician in a prospective study (group 1, healthy controls, with a mean age of 31.22 [± 6.76]; and group 2, patients presenting with cataract, with a mean age of 60.36 [± 10.27]). Patients with ocular surface disease were excluded from this study. Each group responded to the VF-14 questionnaire, underwent an examination with lens opacities assessed by LOCS III and a measurement of ocular light scattering with two platforms: the OQAS (Visiometrics(©)) and the C-Quant (Oculus(©)). We analyzed correlations between indices of light scattering with the two platforms (respectively OSI and log(s)) and traditional quality of vision tests (VF-14 questionnaire and LOCS III)., Results: Strong correlations were found between the OSI and LOCS III. Moderate correlations were found between the OSI and the VF-14 questionnaire, as well as between log(s), VF-14 questionnaire and LOCS III., Conclusion: Indices of light scattering seems to be valid tools to assess quality of vision, thus lending themselves to routine testing of visual function., (Copyright © 2014 Elsevier Masson SAS.
