Effect of the against the rule myopic astigmatism on the near vision of the elderly.

In the two groups of patients with myopic astigmatism the uncorrected near vision was tested after catatract surgery. Each group with 20 patients ages 60-80. All patients enrolled in study have uncorrected far vision 0.5 or better on Snellen tables. In the first group patients were with the rule after surgery myopic astigmatism (1-1.50 Diopter), and in the second group were patients with against the rule after surgery myopic astigmatism (1-1.50 Diopter). Patients in the second group with against the rule astigmatism achieved significantly (p<0.01) better uncorrected near vision.
