Patients who received the AcrySof PanOptix intraocular lens (IOL) (Alcon) with its new diffractive trifocal design achieved satisfactory vision at all distances with a high rate of spectacle independence and very little photic phenomena, Yonca Akova, MD, reported.
This IOL is a one-piece, aspheric, non-apodized diffractive hydrophobic lens with a 4.5-mm central trifocal zone and 15 diffractive zones. The IOL has adds of +3.25 diopters (D) for near vision and +2.17 D for intermediate focus.
She and her coinvestigators conducted a prospective, non-comparative, non-randomized study to evaluate the refractive and visual outcomes and the satisfaction levels of 69 patients (40 men, 29 women; mean age, 64.5 years) after bilateral implantation of this IOL during cataract surgery or refractive lens extraction. All surgeries took place from October 2017 to June 2018. The patients underwent ophthalmologic examinations preoperatively and 6 months postoperatively.
The primary outcome measures were the manifest refraction; uncorrected distance visual acuity (UDVA), intermediate VA (UNVA) at 60 centimeters, and near VA (UNVA) at 40 centimeters; defocus curves, dysphotopsia, spectacle independence, posterior capsular opacification (PCO), and the results of the visual function test-14 (VF-14), Dr. Akova recounted. She is professor of Ophthalmology, Department of Ophthalmology, Bayındır Hospital, Ankara, Turkey.
