Purpose : To investigate the visual outcomes, optical quality and patient satisfaction after implantation of PRECIZON presbyopic NVA (Ophtec BV, Groningen, The Netherlands) intraocular lens (IOL).
Methods : This prospective study included 20 eyes of 10 patients who received cataract surgery and PRECIZON presbyopic NVA implantation. Visual acuity measurement, manifest refraction, slit-lamp examination, autokeratometry, corneal topography, and evaluation of corneal wavefront aberration were performed preoperatively and at 1, and 3 months after surgery. Binocular defocus curve, and contrast sensitivity under photopic and mesopic conditions were also examined at 3 months after surgery.
Results : The mean spherical equivalent (SE) was -1.13 ± 2.29 diopter(D) preoperatively and -0.22 ± 0.42 D at the 3 moths postoperatively. At the 3 months postoperative visit, the mean monocular logMAR visual acuities were as follows: uncorrected distance, 0.03 ± 0.10; corrected distance, -0.02 ± 0.14; uncorrected intermediate (80 cm), 0.14 ± 0.06; uncorrected near (40 cm), 0.17 ± 0.08; and distance-corrected near, 0.20 ± 0.09. The mean binocular logMAR uncorrected visual acuities at distance, intermediate, and near were -0.04 ± 0.08, 0.09 ± 0.05, and 0.12 ± 0.05, respectively. Most patients (80%) were satisfied with their visual outcome.
Conclusion : The PRECIZON presbyopic NVA multifocal IOL provides good visual acuity at distance and near, clinical efficacy, predictability and safety. This multifocal IOL can be a good option for treating cataract and presbyopia.
