“…A long-term study would be particularly useful to provide information on the IOL material stability because hydrophilic IOLs may have calcification. The occurrence of calcification is nevertheless low: in a study of 806 cases of IOLs with the same 26% hydrophilic acrylic raw material as the POD FineVision IOL, Tassignon et al 27 reported only two cases of calcification.…”

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,...

“…Integrating the OCT into the operating microscope opens the possibility of viewing the space of Berger in real time. In this article, we report the first results of a new real-time intraoperative OCT technique to image the space of Berger while performing a planned posterior capsulorhexis for bag-in-the-lens (BIL) cataract surgery [22]. …”

Background: The presence of a space between the posterior capsule and the anterior vitreous was first reported in 1887, but difficulties inherent in examining this structure made it impossible to visualize this area in vivo until now. Estimation of the size of this space was considered to be impossible. Materials and Methods: We utilized an optical coherence tomography (OCT) system attached to the Zeiss Opmi Lumera 700/Rescan microscope (Zeiss Ltd., Jena, Germany) to provide real-time images of the Berger space, the anterior hyaloid and the ligament of Wieger. Results: Imaging in 3 patients provided beautiful, real-time OCT images of the Berger space and of the ligament of Wieger. In one highly myopic eye, there was even evidence of anterior vitreous detachment. Conclusion: Previously unseen transparent structures of the eye can now be imaged intraoperatively using real-time OCT. This new technology seems very promising in achieving a better understanding of the anterior vitreous interface, more specifically of the anterior hyaloid and its posterior capsule attachment by the ligament of Wieger. Changes in the anterior hyaloid and its capsular attachment may contribute to a better understanding of the posterior segment complications after cataract surgery.

“…The demographic characteristics of the cohort are summarized in table 2. The mean age of the patients was 68 years ± 11.2 which was comparable with the mean age of 65.0 years ± 18.3 in the largest reported cohort of BIL surgical patients [16]. Summaries of the duration of diabetes, HbA1c and blood pressures, where obtainable, were included.…”

Assessment of the Bag-in-the-Lens Implantation Technique in Diabetic Patients

Cataract is a common condition observed in patients with diabetes mellitus frequently requiring surgical intervention. The bag-in-the-lens (BIL) intraocular implant is an alternative approach to standard lens-in-the-bag cataract surgery. The lens is supported by anterior and posterior capsulorhexes, which confers a number of advantages in terms of lens centration, rotational stability and prevention of posterior capsular opacity. The purpose of this report is to describe the results of BIL cataract surgery in a retrospective cohort of diabetic patients. Fifty-four cases of BIL surgery are included with a follow-up period of 1 year. Visual acuity outcomes were comparable to previously published standard lens-in-the-bag procedures. There were no reports of posterior capsular opacification and the grade of diabetic retinopathy remained stable. Three cases of clinically significant macular edema were detected over the follow-up period. We conclude that the BIL implantation technique is an advantageous approach to treating cataract in the diabetic population.

Abstract: The BIL IOL met the ISO criteria; that is, primary PCCC was safe in healthy eyes and in eyes with ocular comorbidities and no eye developed PCO over a mean follow-up of 26.1 ± 21.3 months.
