Abstract Details


To evaluate the postoperative outcomes after implantation of a hydrophilic aspheric Precizon® toric intraocular lens, with a transitional conic toric surface, (IOL) for the correction of corneal astigmatism in patients undergoing cataract surgery.


FISABIO OFTALMOLOGIA MEDICA (FOM) Cornea and Refractive Surgery Unit


A total of Fifty-three eyes of 32 patients with cataract received a Precizon toric IOL( model 565, Ophtec) with a cylindrical power between 2.0 and 6 D. Retrospective non comparative clinical study were analysed. IOL power calculation was performed using optical coherence biometry (IOLMaster®). Outcomes of visual acuities, refraction, and IOL rotation were analyzed at the 1st week, 1st, and 3rd month’s evaluations.


Target refraction was emmetropia. Corrected distance visual acuity (CDVA) increased from median 0.3 ± 0,2 preoperatively to median 0.9 ± 0,1 at 3 months postoperatively (p<0.001). Mean preoperative corneal astigmatism was 3.1 ± 0,6 D. The mean preoperative subjective cylinder was -3 ± 1 D and 3 months postoperatively -0.5± 0,4 D(p<0.001). At last follow-up, 36% of the eyes had a residual astigmatism of 1 D, 29.5% of 0.75 D, 11.5% of 0.5 D, 0% of 0,25D and 23% of 0 D. None of this IOLs required realignment.


Precizon® toric IOL showed good postoperative clinical outcomes regarding efficacy and safety in the correction of preexisting regular corneal astigmatism associated with cataract surgery.
