Abstract Details


To evaluate the efficacy and predictability of a toric intraocular lens (IOL), the AMO ZCT model, in cataract surgery for patients with corneal astigmatism


Hospital Universitario Quiron Madrid. Department of Ophthalmology


This prospective study evaluated 50 eyes of 35 patients with cataract and a range of astigmatism between 0.75 and 3 diopters (D) that underwent microcoaxial phacoemulsification (2.2 mm incision) cataract surgery and toric implantation. Pre and 1-month and 6-month postoperative uncorrected and corrected distance visual acuity (UDVA and CDVA, respectively), refractive cylindrical error, IOL misalignment,keratometric and topographic cylinder were analyzed.


Pre and 6-month postoperative logMAR UDVA were 0,82 ± 0.46 and 0.08 ± 0.26 respectively. Pre and 6-month postoperative logMAR CDVA were 0,27 ± 0.29 and 0.04 ± 0.26 respectively. Mean preoperative refractive cylindrical error was 1.94 ± 0.72 D (range 0.75 – 3.5 D) and 6-month postoperative refractive cylindrical error was 0.31 ± 0.32 D (range 0 -1 D). The mean IOL misalignment was 3.1 ± 3.29 degrees. The mean SIA was -0.30 ± 0.42 degrees


Implantation of the ZCT toric IOL during cataract surgery was safe and effective in correcting corneal astigmatism. FINANCIAL DISCLOSURE?: No
