| Sumario: | Zoraida S Gaurisankar,1 Gwyneth A van Rijn,1 Gregorius PM Luyten,1 Thomas JTP van den Berg2 1Department of Ophthalmology, Leiden University Medical Center, Leiden, the Netherlands; 2Institute for Neuroscience, Royal Netherlands Academy of Arts and Sciences, Amsterdam, the NetherlandsCorrespondence: Zoraida S GaurisankarDepartment of Ophthalmology, LUMC, Albinusdreef 2, 2333 ZA, Leiden, the NetherlandsTel +31 71 526 9111Fax +31 71 526 6576Email z.s.gaurisankar@lumc.nlPurpose: To investigate the effect of refractive correction on straylight.Patients and methods: Straylight values were measured with the C-Quant (Oculus Optikgeräte, GmbH, Wetzlar, Germany) in 1) near-emmetropic eyes (n=30) with various negative powered refractive lenses and in 2) myopic eyes (n=30) corrected with prescribed eyeglasses and contact lenses. The straylight measurements in each group were compared in the different conditions.Results: In the near-emmetropic group, a significant effect (p<0.001) of each added negative diopter was found to increase straylight values with 0.006 log-units. In the second group, no significant correlation with type of correcting lens was found on straylight values.Conclusion: Refractive correction with high minus power (contact) lenses result in subtle increase of straylight values. These changes are relatively small and do not lead to visual disability in a clinical setting.Keywords: straylight, contact lenses, eyeglasses, glare, light scatter, refractive error |
