Visual and Patient-Reported Outcomes Following Supplemental Intraocular Lens Implantation for Pseudophakic Refractive Error in Eyes with Complex Ocular Comorbidities

The aim of this case series was to evaluate visual, refractive and patient-reported outcomes, as well as postoperative complications, following AddOn® supplemental intraocular lens (SIOL) (1stQ Deutschland GmbH, Mannheim, Germany) implantation for correcting pseudophakic refractive error in eyes with complex ocular comorbidities. This retrospective longitudinal interventional case series included pseudophakic patients with pre-existing ocular comorbidities who underwent AddOn® SIOL implantation and completed at least 12 months of follow-up. Monocular uncorrected and corrected distance visual acuity (UDVA, CDVA), manifest refraction and postoperative complications were assessed. Patient-reported outcomes, including visual satisfaction and dysphotopsia, were also evaluated. Sixteen eyes of 11 patients were included. Mean (± standard deviation) patient age was 63.27 ± 16.43 years, and mean follow-up was 25.75 ± 7.57 months. Residual refractive error decreased in all eyes following AddOn® SIOL implantation, UDVA improved in most eyes and CDVA remained stable or improved in all eyes, with no loss of corrected visual acuity. No intraoperative or postoperative complications occurred. Patient-reported outcomes showed generally good patient satisfaction, with 75% of patients achieving distance spectacle independence and all patients willing to undergo the procedure again. AddOn® SIOL implantation provided favourable visual, refractive and patient-reported outcomes for correcting pseudophakic refractive error in this retrospective case series of complex eyes. No complications were observed during follow-up. AddOn® SIOL implantation may represent a valuable alternative when corneal refractive enhancement or intraocular lens exchange is unsuitable or associated with increased surgical risk, or when refractive enhancement or intraocular lens exchange is unsuitable or is associated with increased surgical risk.
