Multifokal Progressif Refraktif Difraktif Lens: Optik Tasarım ve Klinik Sonuçları

Pur po se: To evaluate the visual functions of patients who had implantation of new-concept intraocular lens (IOL) OptiVis™, which\udhas aspheric bifocal diffractive and progressive refractive design.\udMa te ri al and Met hod: In this prospective study, 52 eyes of 27 patients had a new multifocal IOL OptiVis™ implantation through\ud2.5 mm incision after cataract surgery with phacoemulsification. 25 of the patients had simultaneous bilateral phacoemulsification\udwith OptiVis™ IOL implantation. Two patients with different multifocal IOL previously implanted underwent monocular OptiVis™\udimplantation. Monocular distance, near and intermediate visual acuities and contrast sensitivity of the patients were recorded. Presence\udof glares and halo, frequency of spectacle use and patients’ satisfaction were questioned.\udRe sults: The mean age of the patients was 71.10±10.60 years and the mean follow-up time was 20.35±13.99 months. The mean monocular\uduncorrected visual acuities of the patients were 0.96±0.11 (Snellen card in decimals) for distance, J1.07±0.26 (Jaeger card) for near (33 cm)\udand J2.25±0.55 for intermediate (60 cm) at 6 months after the operations. The mean best-corrected monocular visual acuities were\ud0.97±0.08, J1.05±0.23 and J2.23±0.54, respectively. The mean monocular contrast sensitivity of the patients under photic conditions were\ud47 in 1.5 cycles per degree (cpd), 73 in 3 cpd, 61 in 6 cpd, 17 in 12 cpd and 2 in 18 cpd. The halo and glare problems which were moderate\udat the first postoperative month, were mild or none in 20 patients (74.07%) and moderate in 7 patients (25.92%) at 3 months after the\udsurgery. Only one patient (3.70%) sometimes needed glasses for far vision. Posterior capsule opacification was seen in 3 eyes (5.76%).\udDis cus si on: OptiVis™, with its diffractive bifocal design, provided very good distance and near vision without any contrast loss.\udAdditionally, this IOL provided considerably good intermediate vision with its progressive refractive design, thus resulted in high patient\udsatisfaction.
