Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose: To assess the relationship between measures of light distortion and retinal straylight in normal and post-LASIK subjects. Design: Cross-sectional, non-randomized, masked observational case series Setting: Clinica Oftalmologica Novovision, Madrid, Spain. Methods: Thirty eyes from 30 healthy subjects (mean age 33.9±8.3 years old; mean spherical equivalent (MSE) -2.06±1.40 D) and thirty six eyes from thirty six refractive surgery patients (mean age 36.1±7.7 years old; mean preop MSE -3.43±2.23 D) were examined with the Starlights and the C-Quant straylightmeter in a case-control study. Results: The age of both treated and control groups was not statistically different (p>0.05). Statistically significant differences between controls and post-LASIK eyes were found for luminous distortion index (LDI), but not for retinal straylight. Correlation analysis yielded significant correlation between retinal straylight Log(s) values and BCVA measures (r=0.379, p=0.002). Control subjects showed significant correlation between MSE and retinal straylight Log(s) values (r=-0.650, p<0.001), while post-LASIK eyes showed a significant correlation between LDI and Log(s) values (r=0.338, p=0.044) and between Log(s) values and BCVA (r=0.460, p=0.005). Correlation between measures obtained by both methods was higher after LASIK than in control eyes, although values were quite scattered in any case. Conclusion: Light distortion phenomena and retinal straylight measures are correlated in both normal and postsurgical eyes. Both parameters are increased in LASIK subjects compared to control non-operated subjects. © 2011 Springer-Verlag.
