Abstract
PURPOSE To determine the prevalence of opacification of a hydrophylic intraocular lens (IOL) with hydrophobic coverage and the percentage of explantations required, determining possible risk factors associated with these opacifications. METHODS This ambispective study enrolled 575 eyes of 296 patients (age 36 to 87 years) that underwent cataract surgery between 2010 and 2017 with implantation of different models of Lentis Mplus IOLs: LS-312-MF30, LS-313-MF15, LS-313-MF30, LU-313-MF30, and LU-313-MF30T (Oculentis GmbH). Visual, refractive, and slit-lamp biomicroscopic changes were evaluated in a long-term follow-up. The percentage of cases with IOL opacification and the percentage of cases in which IOL explantation was required due to such opacifications were calculated at each visit. Five of the explanted IOLs from this series could be analyzed by scanning electron microscopy (SEM-EDX). RESULTS IOL opacification developed in 63 eyes (11.0%). With 95% confidence, the prevalence of IOL opacification was between 842 and 1,401 cases per 10,000 eyes. The time elapsed between surgery and the presence of IOL opacification ranged between 0 and 9.3 years (mean: 4.7 ± 2.2 years). No significant differences in terms of IOL opacification rate were found according to gender (P = .378). No significant differences were found in arterial hypertension, diabetes, hypothyroidism, or hyperthyroidism rates between eyes with or without IOL opacification (P ≥ .053). IOL explantation was needed in 9 eyes (1.57%). SEM-EDX analysis confirmed the presence of rough areas on the IOL surface containing different components, such as calcium, phosphorous, copper, or nitrogen. CONCLUSIONS The prevalence of opacification with time in Lentis Mplus IOLs is high, with no systemic risk factors associated with this complication, suggesting that it may be attributable to the material and/or the manufacturing process.

Qualitative and quantitative analysis of an explanted opacified hydrophilic IOL after over two years from cataract surgery. Eur J Ophthalmol 2023; 33:NP28-NP34. [PMID: 36866563 PMCID: PMC10590018 DOI: 10.1177/11206721221145744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 11/20/2022] [Indexed: 03/04/2023]
Abstract
Opacification of hydrophilic intraocular lenses (IOLs) is an uncommon complication, that can appear after uneventful cataract surgery. We report a case of opacified Hydroview® IOL in a 76-year-old woman, with a previous history of pars plana vitrectomy with silicon oil tamponade in her right eye for a proliferative diabetic retinopathy, who developed an opacification of the IOL after over two years from a silicon oil/BSS exchange in combination with an uneventful phacoemulsification. The patient complained about a progressive decrease in her visual acuity. The slit-lamp examination confirmed the opacification of the IOL. Therefore, because of blurred vision, a combined procedure of explant and exchange of the IOL was performed in the same eye. Qualitative (Optic microscope, X-Ray powder Diffraction (XRD), Scanning Electron Microscopy (SEM)) and quantitative (Instrumental Neutron Activation Analysis (INAA)) analysis of the IOL material were performed. Here, our aim is to report the acquired data of the explanted Hydroview® H60M IOL.

Abstract
PURPOSE To conduct a new exploration and analysis of the ion and fatty acid levels of a medium in which calcified hydrophilic intraocular lenses (IOLs) are present. SETTING Qingdao Eye Hospital of Shandong First Medical University, Qingdao, China. DESIGN Retrospective, laboratory observational case series. METHODS 11 patients (11 eyes) who had implantation of foldable hydrophilic acrylic posterior IOLs were found to have opacification of the IOLs. In vivo and in vitro analyses included the evaluation of patients' clinical characteristics, microscopy, histological staining, energy dispersive X-ray spectroscopy (EDS), the ion level of the aqueous humor (AH) and preserving fluid (PF), and the fatty acid content of AH. RESULTS 10 of 11 cases were female with unilateral opacification, and 7 cases had both-eye cataract surgery, including 1 first eye and 6 second eyes with IOL opacification. 4 types of similar serial numbers were counted. The analysis of AH showed that the concentrations of phosphorus and silicon were elevated but that of calcium decreased, and an increased level of silicon was detected in 3 random PFs. The palmitic (C16:0) and stearic (C18:0) fatty acids were higher than the others in the AH. The EDS confirmed that the IOL surface deposits were composed of calcium, phosphate, and a small amount of silicon. CONCLUSIONS More silicon and higher C16:0 and C18:0 were found in the AH of patients with IOL opacification. New ideas and avenues have been proposed in the study of IOL opacification.

Abstract
We evaluated the influence of intraocular lens (IOL) opacification on the optical performance of explanted hydrophilic acrylic IOLs. We performed a laboratory analysis of 32 Lentis LS-502-1 (Oculentis GmbH, Berlin, Germany) IOLs, explanted due to opacification, in comparison with six clear unused samples of the same IOL model. Using an optical bench setup, we obtained modulation transfer function (MTF), Strehl ratio, two-dimensional MTF, and United States Air Force (USAF) chart images. In addition, we assessed light transmission through the IOLs. The MTF values of opacified IOLs at 3-mm aperture were similar to those of clear lenses, with the median (interquartile range) values of 0.74 (0.01) vs. 0.76 (0.03) at the spatial frequency of 50 line pairs per millimeter in clear and opacified IOLs, respectively. The Strehl ratio of opacified lenses was not lower than that of clear lenses. The USAF-chart analysis showed a considerable reduction in brightness in opacified IOLs. The median (interquartile range) relative light transmission of opacified IOLs in comparison to clear lenses was 55.6% (20.8%) at the aperture size of 3 mm. In conclusion, the explanted opacified IOLs had comparable MTF values to those of clear lenses but significantly reduced light transmission.

Abstract
Purpose To assess the visual and refractive outcomes following exchange of an opacified multifocal intraocular lens (IOL). Patients and Methods A consecutive series of 37 eyes (31 patients) that underwent IOL exchange between November 2015 and May 2021 were included in this study. The indication for surgery in all cases was opacification of a multifocal IOL. Outcome measures included design and anatomical location of the secondary IOL, intraoperative and postoperative complications, visual acuity and refractive accuracy. Results An opacified Lentis Mplus multifocal IOL was explanted from all eyes and replaced with a monofocal IOL in 21 eyes (57%) and multifocal IOL in 16 eyes (43%). Secondary IOLs were implanted in the capsular bag or sulcus or were iris-fixated. IOL exchange was performed at a mean interval of 7 years after the primary surgery. Anterior vitrectomy was required for vitreous prolapse in 9 eyes (24%). Mean corrected distance visual acuity (CDVA) postoperatively was −0.02 ± 0.08 logMAR for eyes with a monofocal secondary IOL and 0.02 ± 0.08 logMAR for eyes with a multifocal secondary IOL. Mean refractive prediction error was −0.57 ± 0.67 D in the multifocal-monofocal group and −0.33 ± 0.59 D in the multifocal–multifocal group. Conclusion An opacified multifocal IOL can be exchanged for a monofocal or multifocal IOL, depending on available capsular support and the patient’s desired refractive outcome. Vitreous prolapse requiring anterior vitrectomy is the most common intraoperative complication. An improvement in visual acuity and a low postoperative complication rate were achieved in this cohort of patients.

Abstract
Purpose: To report the clinical features of patients with opacification of hydrophilic acrylic intraocular lens (IOL) after cataract surgery in neovascular glaucoma.Methods: This retrospective case series included 11 eyes of 10 patients with IOL opacification and neovascular glaucoma (NVG) between January 2006 and December 2010. We included and analyzed cases with opacification of hydrophilic acrylic IOL. An IOL exchange was performed in three cases, and the explanted IOLs were examined grossly and evaluated by light microscopy. Sagittal sections of the optics of the IOLs were evaluated by Von Kossa staining, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX).Results: All 11 eyes of 10 patients were implanted with hydrophilic acrylic IOLs. In addition, there were no cases of hydrophobic acrylic IOL opacification. Nine patients of the 10 patients had diabetic retinopathy and one patient had central retinal artery occlusion. The mean period of IOL opacification after IOL implantation was 19.45 ± 8.52 months and the mean period of IOL opacification after the occurrence of NVG was 14.37 ± 8.51 months. The deposits of the explanted IOLs were shown to consist of calcium by von Kossa staining. The explanted IOLs showed fine whitish irregular granular deposits on the entire anterior surface of the optics by SEM and the presence of calcium deposition was confirmed by EDX analysis.Conclusions: Care is required when using hydrophilic acrylic IOLs in patients with risk of neovascular glaucoma, such as those with diabetic retinopathy or central retinal artery occlusion.

Abstract
PURPOSE We describe the outcomes of intraocular lens (IOL) explantation in a cluster of opaque multifocal Lentis LS-313 following refractive lens exchange (RLE). METHODS Single-centre, single-surgeon, retrospective case series. RESULTS The study enrolled 10 eyes of 10 patients, 6 male and 4 female. All patients had uneventful RLE with multifocal IOL implantation. The mean patient age at the time of RLE was 53 years ± 2.52 (SD). Two eyes had YAG laser capsulotomy prior to explantation. The mean interval between the initial RLE and IOL explantation was 5.4 years ± 1.4 (SD). IOL exchange was performed in all eyes in one procedure. Five eyes had in the bag hydrophobic acrylic IOL (3 multifocal and 2 monofocal), three eyes had 3-piece hydrophobic acrylic IOL in the ciliary sulcus and two had an anterior chamber IOL. Intraoperatively one patient had weak zonules and two patients had zonular dehiscence and required anterior vitrectomy. The mean preoperative CDVA was 0.25 ± 0.15 (SD) logMAR and at the final follow-up, improved to 0.00 ± 0.07 (SD) logMAR (p < 0.01). Light microscopy with von Kossa stain confirmed IOL calcification. No postoperative complications were recorded. CONCLUSIONS IOL exchange appears to be a feasible and safe surgical option for multifocal IOL opacification. However, patients must be warned of additional intraoperative risks including zonular dialysis, vitreous loss, retinal detachment and need for potential scleral or iris fixated IOL or anterior chamber IOL (ACIOL) with its associated sequel of complications. Moreover, YAG laser capsulotomy should be considered carefully as it increases the chances of intraoperative complications and restricts the surgical options of secondary IOL insertion such as in-the-bag IOL exchange with MFIOL.

Abstract
As techniques for modern cataract surgery have expanded and premium intraocular lens (IOL) use is now widespread, patient expectations are high. The need for IOL explantation, whilst still low, remains an ongoing issue. Intraocular lens explantation can be challenging for a number of reasons and as such we have introduced an additional technique to add to the surgeon's repertoire. Bimanual haptic stripping of fibrosis at the specific area where the haptic is adherent to the capsular bag is an effective strategy to aid in dissection of haptics without compromising the capsule or zonules. Given the challenges associated with IOL explantation, newly designed IOLs need to avoid these "sticking points" at which the IOLs interact with the fibrosed capsule. Techniques we have evolved and which are described below should assist anterior segment surgeons to facilitate IOL removal in an efficient and safe way.

Abstract
RATIONALE Only a few cases of intraocular lens (IOL) opacification during phacoemulsification surgery have been reported in the literature; intraoperative emergency due to IOL surface foreign body is even rarer. PATIENT CONCERNS A 76-year-old woman underwent uncomplicated cataract surgery in her right eye. A triangular transparent seemingly foreign body tightly attached to the posterior surface of the IOL was found during IOL implantation; the IOL surface foreign body prevented the patient from obtaining satisfactory visual acuity after surgery. DIAGNOSIS IOL surface foreign body. INTERVENTIONS After confirmation of the surface foreign body by swept-source optical coherence tomography (IOL Master 700), the surface foreign body was removed in a second surgery. After surgery, the IOL was still well centered. OUTCOMES Fortunately, the patient achieved distinctly improved vision without any visual disturbances in her right eye. To identify the material of the foreign body, it was examined by Fourier-transform infrared spectroscopy (FTIR). LESSONS This case suggests that surgeons should carefully observe IOLs before implantation. In addition, effective preoperative planning and skillful surgery can remove foreign bodies smoothly and improve patient vision.

Abstract
Visual impairment resulting from advanced dry age-related macular degeneration (AMD) limits the ability to perform activities required for independent living and adversely affects quality of life. We aimed to determine changes in these parameters in patients with AMD-related geographic atrophy who underwent magnifying cataract surgery (MAGS) using a foldable, bifocal high-add intraocular lens (IOL). The high-add IOL (LENTIS® MAX LS-313 MF 80, Oculentis) was implanted in the better seeing or dominant eye of eligible patients with clinically significant cataract, best corrected distance visual acuity 1.3–0.5 logMAR (20/400–20/63), best corrected near visual acuity >0.8 logMAR (20/125), and stable advanced dry AMD. Self-reported feasibility of performing routine activities and change in quality of life were the main outcome measures. Eleven of 15 operated patients had complete follow-up to 48 months. There were no significant intraoperative or postoperative complications. AMD converted from dry to wet in 2 patients. All patients reported functional gains in the first 3–6 months after surgery, and 10/11 patients reported improved quality of life. From baseline to 48 months, functional performance remained improved in all patients, and quality of life remained improved in the 9 patients with stable AMD. Best corrected distance visual acuity and uncorrected near visual acuity improved in all cases after surgery.
