“…Kim et al compared the clinical outcomes among conventional scleral fixation, retropupillary iris-claw IOL implantation, and intrascleral fixation, and resulted the BCVA as 0.08 ± 0.10, 0.08 ± 0.16, and 0.03 ± 0.04 (logMAR) respectively. 14 In the current study, 30% of patients achieved good vision, while 10% of them achieved poor VA in final visit with a mean postoperative BCVA of −0.37 ± 0.27 logMAR. The reason for variability in postoperative BCVA and refractive outcomes in different surgical methods was related to the several factors such as the length, wide and location of scleral tunnel, the shape of the flanged haptic, and the length of the haptic.…”

Introduction To describe the clinical and refractive outcomes of Yamane transconjunctival sutureless intrascleral intraocular lens (SIS IOL) fixation technique in aphakic and dislocated IOLs. Methods The aphakic and IOL dispositioned patients who underwent Yamane surgery in Bozyaka Research and Training Hospital were evaluated retrospectively. The demographic data, preoperative & postoperative best-corrected visual acuity (BCVA), spherical equivalent (SE), indication for surgery, additional surgical interventions, complications, the final status of retina, and central macular thickness (CMT) through spectral-domain optic coherence tomography (SD-OCT) were recorded. Results A total of 30 eyes of 30 patients were evaluated. The indication for surgery was aphakia in 24 patients, lens dislocation in 1 patient, and IOL dislocation in 5 patients. The mean age of participants was 64.17 ± 14.69 years, and the mean follow-up was 46.07 ± 7.96 months. The mean BCVA was improved from 0.25 ± 0.22 (−0.94 ± 0.83 log MAR) to 0.49 ± 0.24 in decimals (−0.37 ± 0.27 log MAR) (p:0.041). The mean subjective refraction improved from 10.06 ± 3.10 to −1.45 ± 0.73 D in the final visit (p < 0.05). The mean of cylindrical refraction was −1.22 ± 1.03 D in the postoperative period. At the time surgery, 36.6% of patients required at least one additional surgical procedure. During follow-up period, two (6.7%) out of 30 of patients had retinal detachment, two of the patients (6.7%) occured epiretinal membrane, one of the patients (3.3%) had cystoid macular edema. Conclusion Yamane SIS IOL fixation technique is an effective and reliable surgical option in complicated cases that require additional surgical interventions in long-term follow-up.

“…Most intraocular lens studies often report a POM1 visit as it is an The POM1 visit was also extracted in addition to the final BCVA. Studies have demonstrated that most SSFs require multiple months for complete visual recovery [5,20,[22][23][24][25]29,30]. As such, earlier post-operative visits can be used as a method to assess visual recovery.…”

Background: The purpose of the study is to compare the visual outcomes and complications of sutured scleral fixation (SSF), a traditional and conservative surgical approach, and the newer and faster Yamane technique for secondary intraocular lens placement. Methods: A literature search was performed on PubMed, Embase, and Scopus on studies published between 1 July 2017 to 29 September 2023. Outcomes analyzed included the final best corrected visual acuity (BCVA) between 3 and 12 months to assess the effectiveness of the procedure, post-operative month (POM) 1 BCVA to assess the speed of visual recovery, endothelial cell count (ECC), absolute refractive error, surgical duration, and complication rates. Additional subgroup analyses were performed based on surgeon experience with the technique. Single-surgeon studies had an average of 26 procedures performed, whereas multiple-surgeon studies averaged only 9 procedures performed; these were then used to delineate surgeon experience. A sample-size weighted mean difference (MD) meta-analysis was performed across all variables using RevMan 5.4.1; p < 0.05 was considered statistically significant. Results: Thirteen studies with 737 eyes were included: 406 eyes were included in the SSF group, and 331 eyes were included in the Yamane group. There was no significant difference in the final BCVA between groups in both the single-surgeon versus multiple-surgeon studies (MD = −0.01, 95% CI: [−0.06, 0.04], p = 0.73). In the single-surgeon studies, the BCVA at POM1 was significantly improved in the Yamane group compared to SSF (MD = −0.10, 95% CI: [−0.16, −0.04], p = 0.002). In the multiple-surgeon studies, there was no significant difference in BCVA at POM1 (MD = −0.06, 95% CI: [−0.16, 0.04], p = 0.23). The Yamane group had a shorter surgical duration than SSF in both single-surgeon and multiple-surgeon studies (MD = −24.68, 95% CI: [−35.90, −13.46], p < 0.0001). The ECC, refractive error, and complication rates did not significantly differ amongst all groups. Conclusions: The Yamane technique demonstrated similar long-term visual outcomes and complication rates to the traditional SSF. Visual recovery was significantly faster in the Yamane group in the single-surgeon studies. The operative times were shorter across all Yamane groups. Based on these findings, it is advisable to consider the Yamane technique as a viable, and perhaps preferable, option for patients requiring secondary IOL placement, alongside traditional SSF methods.

Purpose: To assess long-term clinical results following bilateral Tecnis Symfony ZXR00 intraocular lens implantation with mini-monovision.Methods: The medical records of cataract patients who underwent bilateral implantation of ZXR00 with intended mini-monovision (target refraction of –0.3 diopters [D] in dominant eye and –0.6 D in nondominant eye) between April 2019 and March 2021 were assessed. Postoperative uncorrected distance visual acuity (UDVA), corrected distance VA (CDVA), uncorrected intermediate VA (UIVA), uncorrected near VA (UNVA), and rate of spectacle dependence for near distance were investigated at 3 months and 2 years after surgery.Results: This study included 61 patients (122 eyes) with average age of 61.8 ± 7.7 years. At 2 years postoperatively, binocular logarithm of the minimum angle of resolution UDVA, UIVA, UNVA, and CDVA were 0.086 ± 0.094, 0.056 ± 0.041, 0.140 ± 0.045, and 0.012 ± 0.024, respectively. The monocular manifest refraction spherical equivalent was –0.31 ± 0.38 in the dominant eye and –0.53 ± 0.47 in the nondominant eye at 3 months postoperatively, and –0.38 ± 0.43 in the dominant eye and –0.61 ± 0.54 in the nondominant eye at 2 years postoperatively. Eight out of 61 patients (13.1%) needed glasses 3 months after surgery, and nine out of 61 patients (14.8%) needed glasses 2 years after surgery.Conclusions: The bilateral implantation of ZXR00s with mini-monovision allows for a good VA at wide range of distance from far to near, thereby resulting in high rate of spectacle independence. These results have held up well even after 2 years after surgery.
