Transscleral fixation of single-piece foldable acrylic lens with eyelets at the optic-haptic junction

Abstract

ObjectiveTo report the clinical outcomes of transscleral fixation using a single-piece foldable acrylic intraocular lens (IOL) with eyelets at the optic-haptic junction (enVista; Bausch & Lomb). DesignRetrospective, noncomparative case series. ParticipantsSixty eyes of 60 patients who underwent transscleral fixation with an enVista IOL were reviewed. MethodsPreoperative patient status, postoperative visual and refractive outcomes, and postoperative complications were analyzed. ResultsThe study included 60 eyes of 60 patients (52 males, 8 females) with a mean age of 56.65 ± 15.57 years. At final follow-up visit, the mean follow-up was 11.40 ± 4.24 months. The mean uncorrected visual acuity (logMAR) improved from 1.95 ± 0.90 to 0.85 ± 0.77 (p < 0.001), and best corrected visual acuity (logMAR) improved from 1.11 ± 1.13 to 0.64 ± 0.70 (p = 0.006). The mean spherical equivalent improved significantly from 6.90 ± 6.10 to 0.21 ± 2.10 D postoperatively (p < 0.001). Complications included transient ocular hypertension (15%), transient hypotony (7%), and hyphema (5%), but no serious complications were observed. In all cases, the IOL remained stable and well centred. ConclusionsTransscleral fixation using a foldable acrylic IOL with eyelets at the optic-haptic junction can be a safe and effective alternative technique to manage cases with broken capsular bag or weak zonular support.
