Abstract Details

Purpose:

To evaluate the visual and wavefront outcomes of patients who underwent cataract surgery with the implantation of a new transitional toric monofocal intraocular lens (IOL) - Precizon Toric IOL (model 565, Ophtec BV).

Setting:

Hospital da Luz, Lisbon, Portugal

Methods:

This prospective case series included 50 eyes with cataract and regular corneal astigmatism between 1.00 and 4.00 diopters (D) submitted to phacoemulsification with implantation of a Precizon Toric IOL. Over a 4-month follow-up period, the main outcome measures were uncorrected and corrected distance visual acuities (UDVA and CDVA, respectively), spherical equivalent (SE) refraction, residual astigmatism, rotational stability of the IOL (OPD-Scan III, Nidek) and higher order aberrations (HOA) (OPD-Scan).

Results:

Mean UDVA was 0.05 ± 0.09 (0.3 to -0.15) LogMAR (P<.001) and mean CDVA was -0.02 ± 0.08 (0.05 to -0.15) (P<.001). UDVA was 0.3 logMAR or better in 49 (98%) eyes and 0.1 LogMAR or better in 43 (86%) eyes. Mean SE refraction was -0.18 ± 0.39 D (-1.12 to +0.50), with 47 (94%) eyes within ±0.50 D of the attempted spherical correction. Mean refractive cylinder was -0.34 ± 0.46 D (-1.00 to 0). Mean toric IOL axis rotation was 1.59 ± 2.15° (0 to 7°). Ocular aberrometry improved after surgery (for HOA RMS p=.002).

Conclusions:

The implantation of the Precizon toric IOL in patients with cataract and corneal astigmatism provided excellent visual outcomes, predictability of refractive results, rotational stability and good optical performance.
