Abstract

To evaluate the misalignment of a new single-piece microincisional hydrophobic acrylic intraocular lens (IOL) in emmetropic, myopic and hyperopic eyes within the first 3 months after surgery. Vienna Institute for Research in Ocular Surgery, Karl Landsteiner Institute, Hanusch Hospital, Department of Ophthalmology, Vienna, Austria. Patients with age-related cataract were included in this prospective study. Each patient received a single-piece microincisional hydrophobic acrylic IOL (AF-1 NY-60, Hoya) in the study eye. Subgroups of emmetropic, myopic and hyperopic eyes were defined according to IOL power calculation. Anterior chamber depth (ACD) measurements were performed with an AC-Master. Tilt and decentration of the IOL were measured with a Purkinje meter. Follow-up assessments were performed 1 h, 3 weeks and 3 months after surgery. Forty-two eyes of 42 patients (21 emmetropic, 10 myopic and 11 hyperopic eyes) were included. The mean ACD 1 h, 3 weeks and 3 months after surgery was 4.597 ± 0.533, 4.483 ± 0.347 and 4.438 ± 0.398 mm, respectively. Differences in ACD between follow-ups and between subgroups were not statistically significant (both p > 0.05). On average, 3 months after surgery IOLs were tilted 0.81 ± 2.86° nasally...Continue Reading
