Results
Other related information Stepwise multiple regression analysis was performed to investigate the relation between several variables and the contrast sensitivity function. The dependent variable was the AULCSF. The explanatory variables included patient age, gender, logarithm of the minimal angle of resolution (logMAR) of uncorrected and corrected distance visual acuities (UDVA and CDVA), the grade of nuclear sclerosis, log(s), and ocular HOAs.
