Abstract Details

PURPOSE: To evaluate the efficacy of the new toric intraocular lens (IOL) Precizon (Model 565, Ophtec BV, The Netherlands), with emphasis on its rotational stability and tolerance for misalignment.


Department of Ophthalmology - Hospital Pedro Hispano, Matosinhos, Portugal


A prospective observational analysis of all patients submitted to Precizon toric IOL implantation between December 2013 and February 2014, with a minimum follow-up time of 6 months was performed. Uncorrected distance visual acuity (UVDA), best spectacle visual acuity (BSCVA), refraction, lens axis, endothelial cell count and complications were registered.


15 eyes with a mean refractive cylinder of 2,66 ±0,9 D were analyzed. The final mean log-mar UDVA and BCSVA significantly improved (p=0,000). UDVA was ≥ 5/10 in 93,3% of the patients and ≥ 8/10 in 86,7%. BSCVA was 10/10 in 93,3%. The mean refractive cylinder significantly improved (p=0,000), with a final mean value of 0,38±0,27D. The mean lens rotation was 3,7±2,8º, with 80% of the patients having lens rotations ≤ 5º. Relative to the target value of residual astigmatism of 0,15±0,21D, the average percentage residual astigmatism was 11% with an average residual astigmatism per degree of rotation of 2,6%. There was one intraoperative complication, namely the breaking of one haptic during the IOL injection, that forced to its explant.


Precizon toric IOL is an effective and reliable option to correct preexisting astigmatism in cataract surgery. This lens not only revealed good rotational stability, but also seems to have a better tolerance to rotation than traditional toric IOL.
