简要总结

Purpose: Comparison of two torical intraocular lenses with differents haptic design in patients with cataract.

Methods: In this prospective, randomized clinical trial 120 eyes of 60 patients underwent phacoemulsification. In patient's eyes the Tecnis torical IOL (Abbott Medical Optics) or the AT Torbi torical 709 MB IOL (Zeiss Medical AG) were randomly implanted. Three months after surgery visual acuity, rotation stability and astigmatism correction were evaluated.
