Short-term Clinical Outcomes after Flanged Intrascleral Fixation of Intraocular Lenses Using Oblique Intrascleral Tunnels

Purpose: To report the short-term clinical outcomes after intrascleral fixation of intraocular lenses (IOLs) using oblique intra-scleral tunnels. Methods: We retrospectively studied 17 patients (18 eyes) who underwent flanged intrascleral IOL fixation from October 2019 to October 2021. The patients were divided into those who underwent fixation using horizontal (group A) and oblique (group B) in-trascleral tunnels. We compared the best-corrected visual acuities (BCVAs), cylindrical powers, refractive errors (the differences between the targeted spherical equivalents [SEs] and postoperative SEs) before and 3 months after surgery, and operating times. Results: At 3 months vs. preoperatively, there were no significant differences in BCVA (-0.83 & PLUSMN; 0.43 vs.-0.48 & PLUSMN; 0.59), refractive error (-0.06 & PLUSMN; 0.97 diopter [D] vs.-0.05 & PLUSMN; 0.80 D), cylindrical power (-0.42 & PLUSMN; 3.81 D vs.-0.33 & PLUSMN; 1.20 D), or operating time (83.33 & PLUSMN; 28.05 minutes [min] vs. 66.33 & PLUSMN; 20.57 min) between groups A and B, respectively. Conclusions: In terms of the short-term clinical outcomes after use of horizontal and oblique intrascleral tunnels, we found no significant differences in any parameters studied. However, use of an oblique intrascleral tunnel may shorten the operating time.
