“…Rohart et al 22 and Taketani et al 23 estimated that hydrophobic lenses caused greater aberrations than hydrophilic lenses. Photic phenomena such as halos or glare in multifocal lenses have been previously reported.…”

ultifocal intraocular lenses (IOLs) enable spectacle independence 1 by providing several points of focus. A new generation of multifocal IOLs, known as trifocal IOLs (designed with three focal points) entered the European market in 2010, with the launch of the FineVision/MicroF IOL (PhysIOL, Liège, Belgium). Many studies describing optical bench testing and clinical outcomes for this IOL have been published since then.The presence of astigmatism in multifocal IOLs scatters each point of focus, resulting in multifocality failure. Therefore, astigmatism correction should also be a surgical goal. An accurate alignment of the toric IOL with the astigmatism axis is key for maximum vision correction. This can only be achieved if the IOL remains stable within the eye (ie, it must not rotate after implantation). The original FineVision/ MicroF IOL, a trifocal IOL model designed for microincision cataract surgery, was adapted with a new double C-loop haptic design that should guarantee the IOL's rotational stability. This new IOL model, which includes a toric component, was named POD FineVision.In this study, we assessed the effect on rotational and capsular centration stability of this new haptic design and whether or not this leads to an improved visual performance to validate the material and the design of the POD FineVision IOL for toric versions. PATIENTS AND METHODS Study deSignIn this randomized controlled trial, we compared the efficacy and rotational stability of two IOLs: a hydrophilic acryl-M ABSTRACT PURPOSE: To compare visual outcomes, rotational stability, and centration in a randomized controlled trial in patients undergoing cataract surgery who were bilaterally implanted with two different trifocal intraocular lenses (IOLs) with a similar optical zone but different haptic shape. METHODS:Twenty-one patients (42 eyes) with cataract and less than 1.50 D of corneal astigmatism underwent implantation of one FineVision/MicoF IOL in one eye and one POD FineVision IOL in the contralateral eye (PhysIOL, Liège, Belgium) at IOA Madrid Innova Ocular, Madrid, Spain. IOL allocation was random. Outcome measures, all evaluated 3 months postoperatively, included monocular and binocular uncorrected distance (UDVA), corrected distance (CDVA), distance-corrected intermediate (DCIVA), and near (DCNVA) visual acuity (at 80, 40, and 25 cm) under photopic conditions, refraction, IOL centration, haptic rotation, dysphotopsia, objective quality of vision and aberration quantification, patient satisfaction, and spectacle independence.RESULTS: Three months postoperatively, mean monocular UDVA, CDVA, DCIVA, and DCNVA (40 cm) under photopic conditions were 0.04 ± 0.07, 0.01 ± 0.04, 0.15 ± 0.11, and 0.16 ± 0.08 logMAR for the eyes implanted with the POD FineVision IOL and 0.03 ± 0.05, 0.01 ± 0.02, 0.17 ± 0.12, and 0.14 ± 0.08 logMAR for those receiving the FineVision/MicroF IOL. Moreover, the POD FineVision IOL showed similar centration (P > .05) and better rotational stability (P < .05) than the FineVision/MicroF IOL. Regarding halos,...

“…This result shows a discrepancy between theoretical design, final IOL manufacturing, and experimental handling. 9 Previous studies [25][26][27][28][29] have analyzed the differences between IOLs in terms of global ocular aberrations; however, this information is affected by the corneal aberrations of the individual eye. This should be taken into account when analyzing the results of the comparisons between IOLs.…”

“…12 Moreover, hydrophilic one-piece IOLs are more flexible and can improve their shapes and reshape better after entering the eye. 9 Because both IOLs were one-piece in our study, this similarity may be the cause of the insignificant difference in coma aberration between the two groups. Coma changes showed a significant increase at the third month versus the first month postoperatively, which is because of the lack of the 13 Although spherical aberration (with respect to the adjustment of these aberrations based on confounding parameters) showed a significant increase over time in our study, no significant difference was observed between the hydrophobic and hydrophilic groups.…”

“…We suggest that these patients be followed for a longer period because Taketani et al 8 and Rohart et al 9 attributed the difference in aberration to the IOL type and shape, but they did not evaluate the effect of the IOL material and biocompatibility. Moreover, because we did not evaluate pseudophakic symptoms subjectively, we suggest that the visual quality of the pseudophakic eyes should be evaluated both objectively and subjectively in future studies to acquire more valuable clinical results.…”
