One Year Outcomes and Stability of a Novel Scleral Anchored Intraocular Lens

Abstract

Purpose. To assess one year results and stability of the implantation of a scleral anchored intraocular lens (IOL). Design. Interventional prospective case series. Methods. Sixty eyes of 60 patients affected by either aphakia or IOL dislocation were included in this study. Patients underwent vitrectomy, scleral fixation of the IOL, and, if present, dislocated IOL removal. Patients were evaluated preoperatively and at 1, 3, 6, and 12 months after surgery by best-corrected distance visual acuity (BCVA) assessment, intraocular pressure (IOP) measurement, corneal specular microscopy, and optical coherence tomography (OCT) of both the macula and anterior segment. Results. At twelve months, mean BCVA significantly improved ( p < 0.0001 ), and none of the patients experienced a decrease of visual acuity. A 10% decrease of endothelial cell count occurred after surgery. Cystoid macular edema occurred in three patients (5%). A transient increase of intraocular pressure was noted in 7 cases (12%). At one month, horizontal and vertical IOL tilt was 1.04 ± 0.87 and 0.74 ± 0.71 degrees, respectively, and did not significantly change in the follow-up ( p > 0.05 ). None of the patients had decentration or dislocation of scleral-fixated IOL during the follow-up. Conclusion. Implantations of scleral plug fixated IOL provide good visual results, low complication rate, and excellent stability of the lens until one-year follow-up.

Flapless and Conjunctiva‐Sparing Technique for Transscleral Fixation of Intraocular Lens to Correct Refractive Errors in Eyes without Adequate Capsular Support

“…Kumar et al found that the tilt angle after glued fixation was 3.2° and 2.9° in horizontal and vertical axes, respectively [ 8 ]. More recently, the study using a novel scleral anchored IOL revealed that the tilt angle was approximately 1° [ 25 ]. The mean tilt angle was 2.33° ± 1.36° in our series, which is lower than 7°, indicating a nonsignificant tilt and is comparable to that of routine cataract surgery.…”

Compare the outcome of different scleral fixation (SFIOL) and retropupillary iris-claw intraocular lens (RPICIOL) in correcting aphakia: a meta-analysis

“…A total of 82 studies were identi ed from the databases, 8 of which were duplicate and excluded 10,11,12,13,14,15,16,17 . Two independent researchers screened the titles and abstracts of the 74 studies, 52 of which were excluded, as they included individual case series (supplementary appendix).…”

Comparison of surgical outcomes of Carlevale sutureless scleral fixation and Artisan Aphakia intraocular lens

“…In 2014, a sutureless scleral fixated IOL was designed by Carlo Carlevale and fabricated by Soleko, Italy. Following the introduction of the Carlevale IOL several authors have reported good surgical outcomes of its implantation (Abed et al., 2021; Barca et al., 2020; D'Agostino et al., 2021; Fiore et al., 2021; Gabai et al., 2021; Januschowski et al., 2021; Rossi et al., 2021; Rouhette et al., 2021; Sidiropoulos et al., 2022; Vaiano et al., 2021; Veronese et al., 2020).…”
