“…Our haptic exposure rate was comparable with another recent study. 25 Our rate of any postoperative cystoid macular edema is greater than reported elsewhere (25.3% FH vs. 10.7% in Patel et al 1 16 ); however, the proportion requiring treatment more intensive than topical drops (i.e., subtenon triamcinolone) was lower at 4.6%.…”

Purpose: Report and compare long-term outcomes and complications of sutureless scleral tunnel (SST) and flanged haptic (FH) scleral fixated IOLs (SFIOL), with spontaneous IOL dislocation as primary outcome measure. Methods: Retrospective single-surgeon case series of 95 SST and 458 FH eyes from 2011-2022 (553 total eyes). Demographics, surgical indications, ocular history, visual acuity and complication rates were collected. Results: Reoperation-requiring spontaneous IOL dislocation rate was significantly different (P=0.0167) between FH (3.7%) and SST (10.5%). Mean follow-up was 3.31±0.30 vs. 1.58±0.07 years for SST and FH, respectively. There was no significant difference between preoperative (20/305 vs. 20/300) or final postoperative (20/77 vs. 20/62) visual acuity. Other complications included any cystoid macular edema (20.0% vs. 25.3%), elevated IOP (16.8 vs. 9.6%), IOL tilt requiring re-operation (5.3 vs. 0%), haptic exposure (2.1 vs. 3.3%), and reverse pupillary block (4.2 vs. 1.1%). Conclusions: Haptic flanging resulted in fewer eyes meeting the primary endpoint of IOL dislocation. We report the longest-to-date follow-up of both non-flanged SST IOL fixation and our FH modified Yamane technique. Our FH modified Yamane technique represents a safe, durable, and potentially superior option for SFIOL.

“…By contrast, their study involved the use of 5-0 and 6-0 polypropylene sutures instead of different haptics materials (PVDF and PMMA) as in our study. 15 Obata et al and Karaca et al described cases of endophthalmitis secondary to an exposed haptic after an intrascleral IOL fixation using the Yamane technique. 10,16 We had no transconjunctival flanges or endophthalmitis cases after a 12-month period of follow-up.…”

Purpose: To compare flange depth for a modified scleral pocket (SP) vs no scleral pocket (NSP) technique (Yamane technique) for intrascleral intraocular lens (IOL) fixation. Setting: Instituto de Oftalmología Santa Fe, Santa Fe, Argentina. Design: Prospective, randomized, single-surgeon, observational study. Methods: Eyes with aphakia and no capsular support were included. They were divided into 2 groups: one was programmed for a double-needle flanged intrascleral IOL fixation as originally described by Shin Yamane with NSP and the second group had a modified SP technique. Flange depth was measured with anterior-segment optical coherence tomography (AS-OCT) at 1 month, 3 months, 6 months, and 12 months postoperatively, and the results were compared. Results: Each group comprised 18 eyes of 18 patients, giving a total of 36 flanges per group. The groups were comparable preoperatively. At 12 months, uncorrected distance visual acuity and corrected distance visual acuity (CDVA) were not statistically different for both groups (P = .333; P = .448). Spherical equivalent (SEQ) was not significantly different between groups at 12 months postoperatively (P = .078). AS-OCT revealed a significantly deeper flange position for the SP group at 1 month, 3 months, 6 months, and 12 months postoperatively (P < .05). Conclusions: When performing a double-needle intrascleral IOL fixation in aphakic eyes with no capsular support, a modified scleral pocket technique provides a significantly deeper flange position with no difference in CDVA or SEQ 12 months postoperatively.

“…Furthermore, I would like to address a discrepancy that has been identified in Table 2 of my article. 1 On closer examination, I agree that there is an error in the table. The corrected Table 2 is presented below.…”
