Abstract Details

Purpose:

Evaluation of rotation and influencing factors of an aspheric 1-piece hydrophobic acrylic intraocular lens (IOL) enVista MX60 within 6 months after operation in over 100 eyes

Setting:

Department of Ophthalmology, Medical University of Vienna

Methods:

An aspheric 1-piece enVista MX60 (Bausch and Lomb) non-toric IOL was implanted in 116 eyes of 60 patients. Predetermined time-steps for measuring the IOL alignment were: End of Surgery (EoS), 1 hour (1h), 1 week (1w), 1 month (1m) and 6 months (6m) after implantation. Axial length (AXL) was measured preoperatively and IOLs were implanted in 4 different intended axis` (0, 45, 90, 135�Â�°) which were randomly assigned. Measurement of Decentration and tilt were conducted with a Purkinje Meter (by Schaeffel) and causes potentially influencing IOL rotation, such as presence of anterior fibrosis were assessed.

Results:

Preliminary results in 20 out of 116 eyes, show varying results. Median absolute rotation (EoS to 6months): 1.5�Â�° [range: 0-14.8�Â�°]. Median rotation EoS to 1h was 1.5�Â�° [0; 12�Â�°], 1h to 1w: 1.6�Â�° [0.1; 4.1�Â�°] and 1w to 1m: 1.0�Â�° [0; 2.4�Â�°]. More results will be presented.

Conclusions:

Rotation stability is a very decisive factor in assessing a decent toric IOL design. Preliminary results show an early variability in the first hour, however a stable IOL alignment was observed following 1 week. For a reliable valuation of the IOL design all follow-ups need to be complete. Influencing factors will be evaluated after last follow-up.
