“…Among the 11 patients who received combined IOL fixation and other procedures, such as PPV and iris reconstruction, there were no significant intraoperative or postoperative complications reported over the longterm follow-up. Moreover, the incidence of complications was far lower than those reported in earlier studies [4,5,[10][11][12][13]. The mean postoperative BCVA was significantly improved compared with that before surgery (0.39 ± 0.56 logMAR vs. 0.89 ± 0.72 logMAR, p < 0.05).…”

Aims To explore the application and long-term clinical effects of modified Yamane technique in intrascleral intraocular lens (IOL) fixation combined with or without iris reconstruction. Settings and design The data of patients receiving IOL fixation with modified Yamane technique in an ophthalmology department between December 2021 and August 2023 were analyzed retrospectively. The longest follow-up duration was > 12 months. Methods and material The trailing haptic was fixed with the needle before the leading haptic. The silicone haptic stoppers were used to stabilize the IOL when iris reconstruction was combined. Preoperative and postoperative best-corrected visual acuity (BCVA), corneal endothelial cells (CECs), postoperative intraocular pressure (IOP), surgical indications and methods, and postoperative complications were recorded. Anterior segment optical coherence tomography (OCT) was used to evaluate IOL decentration and tilt. The paired sample t-test or Wilcoxon rank sum test were used to compare the results of the same index before and after the operation. Results Twelve patients (12 eyes) were included in this cohort. There were 1 case of IOL dislocation, eight cases of lens dislocation or subluxation, and three cases of aphakia. Traumatic lens dislocation was the main cause of aphakia. Primary lens extraction was performed in previous surgeries, and all three were combined with pars plana vitrectomy (PPV). Four of 12 patients underwent IOL fixation and iris reconstruction. The mean age of participants was 63 ± 10.61 years. The mean BCVA increased from 0.89 ± 0.72 logMAR to 0.39 ± 0.56 logMAR at the last visit (p < 0.05). The postoperative relative refractive error was − 0.13 ± 0.42 D (–0.60 D to + 0.57 D). The OCT showed that the IOLs were well centered, with a mean decentration of 0.20 ± 0.13 mm and a mean tilt of 2.31°±0.93°. Ten patients did not experience any complications. Conclusions The modified Yamane technique in IOL fixation surgery, especially combined with iris reconstruction, reduces operation difficulty, increases operational stability and safety, and improves postoperative visual acuity without serious intra- or postoperative complications. The long-term improvement effect was remarkable.

“…Application of foldable three-piece IOLs have been reported in a handful of sutureless scleral fixation techniques ( 2 , 8 ). Given that suture fixation of PCIOLs remains the most widely accepted method for significant long-term stability and safety, we modified it with a special designed foldable three-piece PCIOL in our previous study ( 7 ). The haptic ends of this PCIOL (PY60AD, HOYA Medicals, Shinjuku, Tokyo, Japan) is designed with an enlarged cone shape, which enables us to knot the suture directly at the junction of haptic ends and avoid suture slippage.…”

“…The option of using foldable IOLs remains limited for scleral fixation. In our previous study, a modified technique for scleral suture fixation of a three-piece PCIOL was proposed ( 7 ). While it is a general trend to develop novel fixation techniques for more flexible usage of various designs of IOLs.…”

PurposeTo present the outcomes of a new technique for intrascleral fixation of a flanged three-piece foldable intraocular lens (IOL) without a conjunctival incision.Materials and methodsWe retrospectively reviewed a consecutive series of 12 eyes of 12 patients who underwent scleral IOL fixation using this technique.ResultsThe follow-up period ranged 3–12 months. There was a significant improvement in best-corrected visual acuity, from 0.8 (1.6) logarithm of the minimum angle of resolution (logMAR) preoperatively to 0.45 (0.8) logMAR at the final postoperative follow-up (p = 0.012). Notable complications included one case of pupillary IOL capture and increased intraocular pressure.ConclusionOur novel technique is a viable solution for managing secondary IOL fixation, enabling the use of a wider variety of IOLs and simplifying the reposition process for dislocated three-piece IOLs. This approach has the potential to lower complication rates and enhance patients’ recovery.
