Abstract Details

Purpose:

To evaluate visual and refractive outcomes and rotational stability of the new aspheric Precizon® toric intraocular lens (IOL) (Ophtec, Groningen, The Netherlands) for the correction of corneal astigmatism in patients undergoing cataract surgery.

Setting:

Instituto de Microcirugía Ocular, Barcelona, Spain

Methods:

Prospective, non-randomized case series. Patients with regular corneal astigmatism greater than 0.75 diopters (D) of astigmatism underwent phacoemulsification and Precizon® toric IOL implantation. IOL power calculation was performed using optical coherence biometry (IOLMaster®, Carl Zeiss Meditec), and the Ophtec toric IOL calculation Software (http://calculator.ophtec.com). Preoperative marking was performed using the Robomarker (Surgilum, Wilmington, NC). Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, and IOL rotation were analyzed preoperatively and 3 months postoperatively.

Results:

Precizon toric IOL was implanted in 171 eyes of 119. Three months postoperatively, UDVA was ≥ 20/40 in 89.38% of eyes. None of the eyes lost any line of CDVA. The mean spherical equivalent was reduced from -0.59±3.84D to -0.47±0.70D, with 91.98% of the eyes within ± 1.00 D of attempted correction. The mean preoperative keratometric cylinder was -1.93±1.11 D and the mean postoperative refractive cylinder was -0.78±0.82D, with 84.56% of the eyes within ± 1.00 D of attempted cylinder correction. Three (1.7%) IOLs required realignment due to intraoperative positioning error. Twelve (7%) eyes required enhancement with corneal refractive surgery.

Conclusions:

Precizon® toric IOL showed excellent visual and refractive outcomes, as well as very good rotational stability and safety, in the correction of preexisting regular corneal astigmatism in patients undergoing cataract surgery.
