Astigmatic axis affects visual acuity after refractive surgery
The axis of astigmatism has a small but definite effect on uncorrected distance vision in eyes that achieved emmetropic spherical equivalent after laser refractive surgery, according to a study.A retrospective cohort of 17,436 eyes of 8,718 patients who underwent LASIK or PRK at the Care-Vision Laser Centers in Tel Aviv, Israel, was divided into three groups according to the steep astigmatic axis: with-the rule (WTR), oblique and against-the-rule (ATR). The oblique group was further divided into oblique WTR and oblique ATR. Uncorrected distance visual acuity (UDVA) was compared among the (Read more...)
