This retrospective observational multicentre cohort study compared the rate of postoperative cystoid macular oedema (CME) between two intraocular lens (IOL) scleral fixation (SFIOL) techniques: a flanged IOL fixation technique (Yamane technique) and a suture IOL transscleral fixation technique (conventional technique). The study included 207 eyes with postoperative CME that had undergone SFIOL and were observed for > 12 weeks between January 2019 and January 2021. The primary endpoint was a comparison of the rate of postoperative CME at 3 months between groups. Secondary endpoints were a comparison of postoperative best-corrected visual acuity (BCVA) at 3 months between groups and an analysis of characteristics associated with postoperative CME in the Yamane technique group. The Yamane technique group developed postoperative CME in 13.0% of eyes at 3 months, compared with 1.9% in the conventional technique group (odds ratio: 7.99, P = 0.045). Postoperative BCVA was consistently significantly higher in the Yamane technique group. Although many retinal surgeons have performed the Yamane technique because of its convenience for SFIOL, our findings suggest that the Yamane technique carries an increased risk of postoperative CME compared with the conventional suture method. Therefore, careful management of postoperative CME is needed after SFIOL.

Article Synopsis
- This study examined the effectiveness of bone SPECT imaging with and without SwiftScan technology in patients with prostate cancer bone metastases.
- Involving 10 patients and 130 metastatic lesions, the research compared the quality of images produced at various acquisition times, showcasing improved quality scores and correlation coefficients with SwiftScan.
- Findings indicated that SwiftScan allowed for a 50% reduction in acquisition time while still maintaining acceptable image quality and accurate quantitative measurements like SUV and contrast-to-noise ratios.
Comparing dislocation force between a flanged haptics IOL and a harpoon haptics IOL.

To compare two different secondary IOL fixation techniques, either flanged or hooked, regarding the least required force to dislocate the haptic in human corneoscleral donor tissue (CST). Experimental laboratory investigation. The least required dislocation force (LRDF) of two different fixation techniques, namely the flanged haptics (FH, as described by Yamane) and the harpoon haptic technique (HH, as described by Carlevale) were investigated using 20 three-piece IOLs (KOWA PU6AS) and 20 single-piece IOLs (SOLEKO CARLEVALE) fixated to human scleral tissue.

Purpose: To evaluate the outcomes of scleral-fixated intraocular lenses (IOLs) implanted using either Yamane technique or Gore-Tex suture fixation, in comparison to intracapsular lens fixation, and to assess the efficacy of various lens formulas in achieving predicted refractive targets.
Patients And Methods: This study included 45 eyes from 44 patients with scleral-fixated IOLs, comprising 37 Yamane eyes and 8 Gore-Tex eyes. Preoperative refractive predictions from various formulae were compared with final postoperative refraction.
Recent advances and current challenges in suture and sutureless scleral fixation techniques for intraocular lens: a comprehensive review.

Over the past two decades, both suture and sutureless techniques for scleral fixation of intraocular lenses have seen significant advancement, driven by improvements in methodologies and instrumentation. Despite numerous reports demonstrating the effectiveness, safety, and superiority of these techniques, each approach carries with it its own drawbacks, including an elevated risk of certain postoperative complications. This article delves into various surgical techniques for scleral fixation of posterior chamber intraocular lenses, discussing their procedural nuances, benefits, drawbacks, postoperative complications, and outcomes.
