This study evaluated the distribution of ocular biometric parameters and characteristics of corneal astigmatism measured using the IOLMaster device in cataract patients residing in Central China. Studies of corneal astigmatism in cataract patients from Southern [1, 11], Northern [9] and Eastern [10] China have previously been published. We compared these previous results with those in the present study and found that the corneal power in patients from Northern China was greater than that in other different regions, while the difference among other areas was not obvious. The highest astigmatism in patients from the four areas did not exceed 7.00 D, but the percentage of cataract patients with astigmatism higher than 1.00 D was the greatest in Northern China. This is probably attributed to a regional difference in the populations, as well as different environmental and life style factors [12].
