Outcomes of the flanged intrascleral haptic fixation with double-needle technique in patients with Marfan syndrome

Abstract

Purpose:

To investigate the clinical outcomes and complications associated with the flanged intrascleral haptic fixation with double-needle technique (a.k.a. the Yamane technique/FIHFT) in patients with Marfan syndrome (MFS) with subluxated or dislocated lenses.

Methods:

Eighteen eyes of 11 patients with MFS with subluxated or dislocated lenses who had undergone intraocular lens implantation using the FIHFT from March 2019 to October 2020 were evaluated. All patient data were retrospectively collected from medical records, including a complete ophthalmologic examination at baseline and follow-up examinations of uncorrected visual acuity (UCVA, logMAR), best-corrected visual acuity (BCVA, logMAR), intraocular pressure (IOP), and slit-lamp examination.

Results:

The median follow-up period was 6 ± 3 (range, 3–12) months. The average patient age at the time of surgery was 13 ± 9 (range, 4–34) years. The mean preoperative BCVA was 0.49 ± 0.20 logMAR (Snellen equivalent visual acuity, 20/60), while the mean postoperative BCVA at the end of follow-up was 0.21 ± 0.14 logMAR (20/30), indicating an improvement of 0.28 ± 0.20 logMAR (20/40) postoperatively (p < 0.001). Postoperative iris capture occurred in six eyes (38.9%). No cases of hypotony, IOP elevation, or vitreous hemorrhage were noted, and no patients developed intraocular lens dislocation, retinal detachment, or endophthalmitis.

Conclusions:

To our knowledge, the present study is the first to report outcomes of the FIHFT in patients with MFS. Our findings suggested that scleral lens fixation is safe and effective for improving visual acuity in patients with MFS who have subluxated or dislocated lenses.
