Purpose

To report the clinical outcomes, observations, and complications related to sulcus implantation of the Lumina accommodative intraocular lens (IOL) over a 24-month period.

Setting

This prospective, observational multicenter study included 103 eyes from 66 patients who underwent implantation of the Lumina accommodative intraocular lens (IOL) at two specialized centers, each employing a distinct sulcus-based implantation model. 

Methods

At Resbiomed-Vissum Eye Clinic (Sofia, Bulgaria), 54 eyes were treated using the Initial Model, in which the main corneal incision was aligned with the patient’s positive corneal meridian. In contrast, at Vissum Instituto Oftalmológico (Alicante, Spain), 49 eyes were treated with the Optimized Model, characterized by a standardized horizontal access tunnel (0–180°), regardless of corneal topography.Patients were evaluated at predefined postoperative intervals (1 day; 1, 3, 6, 12, and 24 months). Visual and refractive parameters along with postoperative observations and complications, were systematically documented.

Results

On day one, mild transient findings occurred in 21.3% of eyes, including corneal edema, ocular hypertension, pigment dispersion, and IOL tilt. By one month, events decreased to 8.7%, with isolated cases of decentration and macular edema. From month three onward, complications were rare (<1%), while between 12 and 24 months, minor late findings included pigment deposits, decentration, and delayed ocular hypertension (2.9%). Visual outcomes were favorable in both cohorts, with UDVA, CDVA, UNVA, CNVA, and CDNVA showing excellent performance at 24 months.

Conclusions

The Lumina IOL exhibited a favorable long-term safety profile, with no major sight-threatening adverse events. Early postoperative observations were transient and clinically insignificant, while late complications—though likely lens-related—did not compromise visual quality. These findings support the anatomical and functional safety of sulcus implantation for accommodative IOLs, confirming its viability as an effective and stable alternative to capsular bag fixation.
