Purpose: Intraocular lens (IOL) fixation using a sutureless 27-gauge needle intrascleral IOL implantation technique requires six surgical wounds. We developed a modified technique using two 27-gauge trocars for vitrectomy and indwelling flanged IOL haptics to reduce the number of surgical wounds. Setting: Methods: Patients who underwent IOL scleral fixation and were observed for >12 weeks were analysed using medical record data. Before October 2017, patients underwent normal flanged IOL scleral fixation. Between November 2017 and April 2019, patients underwent the modified method (flanged IOL via 27-gauge trocars with double-needle technique). Primary end-point was superiority or non-inferiority of modified IOL scleral fixation compared with normal IOL scleral fixation for visual acuity (VA). Changes in corneal endothelium cell number, refractivity, astigmatisms and surgery-related complications, were secondary end-points. Results: There were no significant differences in baseline characteristics between groups. Raw VA and best collected VA (BCVA) were significantly improved in all eyes (pÀ). There were no statistical significances in raw VA, BCVA and surgery-related complications between groups. Conclusions: Results of the modified technique were not inferior compared with the original technique although it was less invasive. Therefore, flanged IOL fixation via trocars using a double-needle technique is a useful technique for IOL implantation.Key words: intraocular lens implantation -intraocular lens scleral fixation -micro incision vitrectomy surgery -pars plana vitrectomy -surgery technique Acta Ophthalmol. 2020: 98: e499-e503

“…12 In order to overcome these challenges, several modifications were developed adding more value to the technique described by Yamane concerning its applicability and practicality. [12][13][14][15]22 In the current study, the 2 mm scleral tunnel and sclerotomy were done by the insertion of 25-gauge vitrectomy trocar preloaded with microcannula, leaving the microcannula in place, through which 25-gauge retinal forceps grasped both the leading and trailing haptics effortlessly compared to the 30-or 27-gauge needle used by Yamane. This allowed for a shorter operative time, with less intraocular maneuvers and avoided the hazards of the presence of a bent needle in the posterior chamber.…”

Purpose To study the safety and efficacy of 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation in patients with insufficient posterior capsular support. Methods Five aphakic eyes with capsular insufficiency were included in this prospective interventional case series study, at Dar El Oyoun Hospital, Cairo, Egypt. Twenty five-gauge trocar-assisted flanged intrascleral sutureless technique was used for IOL fixation, in which retinal microforceps were used to capture and externalize both haptics through a scleral tunnel. CDVA, IOP measurements and IOL centralization were reported pre- and one day, one & 3 months postoperatively. Any intra- or postoperative complications were recorded. Results The mean LogMAR CDVA had significantly improved one day, 1 & 3 months postoperatively (0.74 ± 0.1, 0.42 ± 0.07 and 0.26 ± 0.08 respectively, p < 0.001) compared to the preoperative value (1.7 ± 0.17). The mean IOP showed no significant changes along the follow-up period (16.9 ± 0.1; 16.2 ± 1.1; 16.3 ± 0.9 mmHg, p = 0.68, 0.58, 0.89) respectively at 1st day, 1 & 3 months postoperatively) compared to the preoperative measurement (16.4 ± 1.8 mmHg). The IOL was found to be centralized in all cases. No intra- or postoperative complications were encountered. Conclusion 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation is found to be a reliable and effective technique that overcomes Yamane technique's challenges for IOL fixation in cases with posterior capsular insufficiency.

“…Owing to these factors, we often observe IOL dislocation or exposure of the flanged haptic, and it is sometimes difficult to reposition the IOL. Therefore, many surgeons have been trying to modify the technique for the better [ 23 , 24 , 26 ]. We considered methods to develop a fool proof technique for intrascleral fixation of IOL with fewer intraocular manipulations.…”

A new method for intraocular lens (IOL) fixation in the scleral tunnel using two common 27G blunted needles and an ultrathin 30G needle with fewer intraocular manipulations was developed. Half-depth scleral flaps were prepared, and vertically angled sclerotomies were performed under each scleral flap, 2 mm from the limbs with a 20G microblade or a 26G needle. Two bent 27G blunted needles connected the sclerotomy and corneoscleral incisions. One haptic was inserted into this bent 27G blunted needle extraocularly and extruded through the sclerotomy site. Each haptic was inserted into the lumen of the preplaced ultrathin 30G needle and buried into the scleral tunnel. In this retrospective study, we reviewed the outcomes of this new technique in patients with at least 3 months’ follow-up data. Iris capture of the IOL was not observed in any case, and IOL repositioning was not performed either. Astigmatism induced by intraocular aberration was almost as same as that with other methods. Our technique can be performed in any operation room without any extra instruments. This trial is registered with UMIN000044350.
