Abstract Details

Purpose:

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.

Setting:

Hospital de Braga, Braga, Portugal

Methods:

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).

Results:

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.

Conclusions:

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.
