Purpose

To assess visual and refractive outcomes, defocus curve, contrast sensitivity, halos and glare, and patient satisfaction following full-range focus intraocular lens implantation with AI-designed spiral optics.

Setting

Clínica Baviera-AIER Eye Group, Spain

Methods

Prospective study in 20 presbyopic patients. Bilateral lens surgery and RayOne Galaxy IOL implantation. Follow-up visits three months after surgery. Visual acuity was measured: uncorrected distance (UDVA) and corrected (CDVA) at 4 m, uncorrected intermediate (UIVA) and corrected (DCIVA) at 66 cm, uncorrected near (UNVA) and corrected (DCNVA) at 40 cm. Defocus curve (DC) and contrast sensitivity (CS) (CSV-1000) were studied mono and binocularly. Halo and glare size and intensity were assessed (halo and glare simulator, ViSU-L GmbH). Patient-reported outcomes (PROM) were assessed with CatQUEST-9SF, RayPRO (automatic patient follow-up questionnaire) and the patient's own questionnaire.

Results

Binocular visual acuity (VA) (logMAR) was: UDVA 0.01±0.05 logMAR and CDVA -0.01±0.02 logMAR; UIVA 0.06±0.06 logMAR and DCIVA 0.05±0.05 logMAR; UNVA 0.11±0.08 logMAR and DCNVA 0.11±0.07 logMAR. 100% achieved binocular VA ≥0.2 logMAR at distance and intermediate and 94% achieved VA ≥0.2 logMAR at near, with and without correction. Binocular DC (logMAR) showed a smooth plateau from +0.5 D to -2.5 D, and VA ≥0.2, ranging from ~4.0 D. Binocular CS (3, 6, 12, and 18 cycles per degree) was 1.56 ± 0.05, 1.80 ± 0.17, 1.50 ± 0.15, 0.93 ± 0.25 logMAR, respectively. Halo and glare were very mild in size (mean halo 32.60 ± 11.35 and 1.45 ± 6.48 glare) and intensity (mean halo 32.95 ± 15.31 and 1.85 ± 8.27 glare). PROMs were excellent.

Conclusions

Binocular visual acuity showed excellent results for far, intermediate and near distances. Results remained stable between the one-month and three-month follow-up. The results demonstrate that the novel full-range IOL, with a unique spiral design, provides high visual quality at various distances. These findings suggest that patients can achieve a high level of vision, spectacle independence and satisfaction, similar to what we achieved with diffractive trifocal IOLs.
