Early Visual And Refractive Outcomes Following Bilateral Implantation Of The Spiral Galaxy Intraocular Lens: Initial Clinical Experience

To evaluate the early visual and refractive outcomes following bilateral implantation of the novel Rayner Spiral Galaxy IOL — a non-diffractive, full-range-of-focus intraocular lens (IOL) designed with an AI-derived spiral optic — with emphasis on distance, intermediate, and near uncorrected visual acuity and patient visual independence.

Prospective, single-center observational case series at a tertiary ophthalmic center performing standard phacoemulsification cataract surgery with premium lens implantation.

Patients undergoing routine bilateral cataract surgery received the Spiral Galaxy IOL. Inclusion criteria comprised visually significant cataract and a desire for presbyopia correction without planned monovision. Standard biometry and IOL power calculations were performed. Postoperative assessments included uncorrected distance visual acuity (UDVA, 6 m), uncorrected intermediate visual acuity (UIVA, ~66 cm), and uncorrected near visual acuity (UNVA, ~40 cm) at 1, 3, and ongoing follow-ups. Early results are summarized here (n ≈ 100 implants). Patient-reported dysphotopsia and spectacle dependence were recorded. Pending 6-month outcomes will be incorporated prior to final submission.

Among approximately 100 patients bilaterally implanted with the Spiral Galaxy IOL:

• Distance vision: 97 % of patients achieved UDVA equivalent to 6/6 or better.

• Intermediate vision: 95 % achieved 6/6 or better at intermediate working distance.

• Near vision: 96 % achieved N6 or better uncorrected performance.

No significant intraoperative complications occurred. Preliminary outcomes suggest excellent refractive predictability with a high proportion of patients within ±0.50 D of target spherical equivalent (data to be finalized). Subjectively, patients reported minimal dysphotopsia and high levels of spectacle independence across distances.

Early results with the Spiral Galaxy IOL show highly favorable visual acuity across all distances, with the majority of patients achieving excellent distance, intermediate, and near vision without corrective spectacles. These outcomes align with contemporary innovations in full-range-of-vision optics, offering an alternative to traditional diffractive multifocal lenses with the potential for reduced dysphotopsia and seamless focus transition. Pending completion of 6-month follow-up and statistical analysis, these findings support the Spiral Galaxy IOL as a promising option for cataract patients seeking broad spectacle independence.
