Abstract
Purpose To evaluate the effect of asphericity and blue light filter (BLF) of three different intraocular lenses (IOLs) on the visual performance, second- and third-order aberrations (defocus, coma, trefoil), and contrast sensitivity after uneventful cataract surgery.MethodsOne hundred and twenty eyes of 60 patients with clinically significant cataract were randomly assigned to receive one of the three IOL types: Bioline Yellow Accurate (aspheric, with BLF, i-medical, Germany), BioAcryl 60125 (spherical, without BLF, Biotech, France), and H65C/N (aspheric, without BLF, PhysIOL, Belgium). Each IOL was implanted in 40 eyes. Complete ophthalmologic examination, functional acuity contrast testing and wavefront analysis were performed 60 days postoperatively.Results The mean postoperative best-corrected visual acuity (BCVA) was 0.95 0.08, not differing statistically among the IOL groups (P = 0.83). Mean defocus and coma values did not yield any statistically significant difference through the IOL groups varying from –0.784 to –0.614 μm and 0.129 to 0.198 μm (P = 0.79 and 0.34, respectively). Bioline Yellow Accurate IOL presented less trefoil aberrations, 0.108 0.05 μm, compared to the other two IOL types (BioAcryl [0.206 0.19 μm] and Physiol [0.193 0.17 μm], P 0.05). Contrast sensitivity values did not differ among the groups under all lighting conditions. Bioline Yellow IOL showed a statistically higher loss of contrast sensitivity (between mesopic and mesopic with glare conditions) compared to the BioAcryl and PhysIOL in 12 and 3 cpd spatial frequencies, respectively (P 0.05).ConclusionBioline Yellow IOL indicated lower contrast sensitivity under mesopic conditions when glare was applied but resulted in less trefoil aberrations after uneventful cataract surgery. No further differences were noted in postoperative visual performance among three IOL groups.
Highlights
In order to achieve the best outcome after phacoemulsification, the intraocular lenses (IOLs) implantation should result in minimal aberrations and high-contrast sensitivity
We compared the visual performance after the implantation of three different IOLs; one aspheric, with blue light filter (BLF); one aspheric, without BLF; and one spherical, without BLF
Our results showed that best-corrected visual acuity (BCVA) did not differ statistically significantly among the IOL groups
Summary
Modern cataract surgery has recently evolved into a refractive procedure aimed at improving. Aspheric and Blue Light Filtering IOLs; Tzamalis et al visual quality in addition to increasing the visual acuity. It is routinely combined with the implantation of intraocular lenses (IOLs) of various materials and designs
