Abstract Details


To evaluate the refractive outcomes and rotational stability of the PRECIZON Toric IOL (Ophtec) for the correction of preexisting corneal astigmatism in patients undergoing routine cataract surgery.


Hospital de Braga, Braga, Portugal


Patients with cataract and corneal astigmatism > 1,5 diopters (D) measured by ALLEGRO Biograph (Wavelight) were included in this prospective study. Pentacam HR (Oculus) was performed in all patients pre-operatively and the cornea was marked in the sitting position with a pendulum marker. The minimun follow-up was 1 month. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), residual refractive sphere, residual keratometric and refractive cylinders, and toric IOL axis were measured before and 1 day, 1 week, and 1 month after surgery. IOL misalignment and rotational stability were assessed by retroillumination photographs and by OPD-SCAN III (Nidek).


Fourteen eyes of 8 patients were included in this study. The mean pre-operative corneal astigmatism was 3,44D. The mean cylinder reduction was approximately 70% with a mean post-operative refractive cylinder of 1,1D. The mean post-operative UDVA was 0,68. Mean IOL rotation was 3,5 degrees with all eyes with an IOL rotation inferior to 10 degrees. No complications were observed.


Implantation of the PRECIZON Toric is a safe and effective method to correct corneal astigmatism in patients undergoing routine cataract surgery. The IOL showed a good rotational stability.
