“…The subluxated IOL was later repositioned using the double-needle Yamane technique. [ 21 ] The IOL haptic was composed of PVDF and was shortened for repositioning. Due to the relative fragility of the subluxated PMMA haptics in our case series, the Yamane technique may not be the preferable technique to reposition the haptic to prevent haptic damage during manipulation.…”

PURPOSE: The purpose of the study was to report the complications of sutureless intrascleral (SIS) intraocular lens (IOL) fixation and its management. MATERIALS AND METHODS: A multicenter, retrospective, consecutive interventional case series of patients with intra or postoperative complications after SIS IOL fixation during the technical learning curve of vitreoretinal surgeons from three Taiwanese referral hospitals. The used surgical techniques were the Scharioth technique for intrascleral tunnel fixation, Yamane technique (double-needle scleral fixation), and modified Yamane technique (double-needle flanged haptic scleral fixation). The IOL models and surgical instruments used as well as each patient’s ocular characteristics and complication management were recorded. RESULTS: Of the eight included patients, the complications of 3 (37.5%) and 5 (62.5%) were noted intraoperatively and postoperatively, respectively. Haptic-related complications, including haptic breakage, slippage, and haptic disinsertion, occurred in six eyes. Other complications included uveitis–glaucoma–hyphema syndrome, retinal detachment, and IOL tilt. For the two patients with haptic slippage, repositioning was achieved using a modified cow-hitch technique that resulted in favorable IOL centration and restored visual acuity. CONCLUSION: Most complications surgeons encountered during their early exposure to SIS IOL fixation were haptic related. Surgeons should be aware of such complications to prevent and manage them during surgery. Our modified cow-hitch technique could be used to reposition IOLs with unilateral haptic slippage.

“…As previously reported, another technique of trimming the flange tip was considered at the initial stage. 4 The dropped flanged haptic can be captured and externalized at the limbal side port by intraocular forceps before trimming the flanged tip. Thereafter, the trimmed haptic can be inserted into the 27-gauge needle by the conventional steps.…”

To report the development of a novel, simple-to-use technique for the salvage of a haptic of dislocated flanged intraocular lens during a retinal detachment surgery.Methods: A 25-gauge regular-wall needle was prepared and threaded by the dislocated flanged haptic before the flanged haptic was heated and enlarged by low-temperature cautery.Results: The dislocated flanged haptic was probably the result of too small of a diameter of the previously flanged haptic and was triggered by scleral indentation. The rescue technique required only a 25-gauge regular-wall needle to conduct the conventional procedure of flanged haptic intraocular lens fixation before being enlarged by lowtemperature cautery. The intraocular lens remained centered and stable at a 3-month postoperative follow-up examination. Conclusion:The application of a 25-gauge needle in the salvage of a haptic of dislocated flanged intraocular lens is simple and effective without the need for trimming the flanged tip.

Background This study aimed to investigate the safety and efficacy of the Yamane technique (flanged intrascleral haptic fixation with double-needle technique /FIHFT) for three-piece intraocular lens (IOL) implantation in Egyptian patients diagnosed with Marfan syndrome (MFS) presented with subluxated lenses (ectopia lentis, EL). Methods This was a retrospective evaluation of thirty-three patients who were diagnosed with MFS and had subluxated lenses in a total of forty eyes. Seven of these patients had bilateral subluxation. Lensectomy or phacoemulsification was performed with limited anterior vitrectomy, followed by IOL implantation using the FIHFT method. Data was collected from medical records, including preoperative and postoperative corrected distant visual acuity (CDVA) using logarithm of the minimal angle of resolution (log MAR), preoperative and postoperative refractions, intraoperative and postoperative complications, and follow-up periods. Results The mean age of patients in the study was 30.79 years, with a mean follow-up of 23.9 months. Post-surgery, the refractive sphere decreased significantly from -9.1 ± 1.4 diopter (D) to -1.4 ± 0.7 D, and cylinder measurements dropped from -4.5 ± 0.8 D to -1.4 ± 0.6 D. The spherical equivalent (SEQ) also declined from -11.4 ± 1.5 D to -2.1 ± 0.8 D. The CDVA improved from 0.80 ± 0.32 to 0.18 ± 0.10 log MAR ( P < 0.001). No intraoperative complications were identified. Postoperative complications included IOL decentration (12.5%), vitreous hemorrhage (7.5%), IOL slippage (5%), IOL tilt (5%), and retinal detachment (RD) (5%). Further surgical procedures were necessary for only four cases (10%), all of which had positive outcomes. IOL tilting and slippage occurring at average ages of 18 and 19 years, respectively. No other complications, such as hypotony, elevated intraocular pressure (IOP), corneal edema, iritis, IOL dislocation, cystoid macular edema (CME) or endophthalmitis, were reported. Conclusions The Yamane technique has proven effective and safe for treating subluxated lenses in Egyptian patients with Marfan Syndrome, resulting in improved visual acuity with minimal complications, mostly minor and manageable. Comprehensive fundus examinations before and after surgery are essential for promptly identifying retinal breaks and reducing the risk of retinal detachment. IOL tilting and slippage are more common in younger patients. Supplementary Information The online version contains supplementary material available at 10.1186/s12886-024-03724-y.
