PURPOSE: To compare the aberrometric profile of the Artisan Aphakia lens (Opthec BV) and transscleral plug FIL-SSF lens (Soleko) and to assess the impact of tilt and decentration on their optical performance.
METHODS: This retrospective observational study was conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy, with a consecutive cohort of aphakic eyes undergoing secondary lens implantation with an Artisan or FIL-SSF lens. Wavefront analysis was performed using a pyramidal wavefront-based aberrometer (Osiris-T; CSO). Tilt and decentration were calculated using anterior segment optical coherence tomography (MS-39; CSO).
RESULTS: The study included 47 eyes from 45 patients: 24 eyes in the FIL-SSF group and 23 eyes in the Artisan group. Decentration was 0.39 ± 0.14 mm in the FIL-SSF group and 0.51 ± 0.16 mm in the Artisan group (P = .02). The mean tilt value was 6.6 ± 2.35 degrees in the FIL-SSF group and 5.9 ± 1.86 degrees in the Artisan group (P = .13). Internal higher order aberrations (HOAs) were 0.23 ± 0.07 μm in the FIL-SSF group and 0.29 ± 0.13 μm in the Artisan group (P = .02). The point spread function (PSF) Strehl ratio was 0.12 ± 0.05 in the FIL-SSF group and 0.10 ± 0.04 (P = .11) in the Artisan group. The PSF Strehl ratio without lower order aberration (PSFw2) was 0.28 ± 0.12 in the FIL-SSF group and 0.23 ± 0.09 in the Artisan group (P = .01).
CONCLUSIONS: The Artisan and FIL-SSF lenses provide comparable optical performance in terms of the PSF Strehl ratio. However, the Artisan lens appears to be more susceptible to decentration, which may result in increased higher order aberrations and a consequently lower PSFw2 Strehl ratio.
