Lumina accommodating IOL improves near visual acuity, contrast sensitivity

A new accommodating IOL improved visual function, accommodation and contrast sensitivity, according to a study.

The study authors compared visual acuity, accommodation and contrast sensitivity with the Lumina accommodating IOL (AkkoLens) vs. a standard monofocal IOL.

The Lumina IOL is positioned in the sulcus plane in front of and atop the capsular bag. It is controlled by the ciliary muscle, without interference of the capsular bag, allowing the eye to focus continuously from far to near, the study authors said.

The prospective randomized study included 86 eyes that underwent cataract surgery and subsequent IOL implantation; 61 eyes received a Lumina IOL, and 25 eyes served as a control group and received an AcrySof SA60AT monofocal IOL (Alcon).

Uncorrected and corrected distance visual acuities improved significantly in both groups (P .03) and were similar between the groups at 12 months postoperatively.

Uncorrected near visual acuity was 0.07 logRAD in the Lumina group and 0.37 logRAD in the control group at 12 months; the difference was statistically significant (P < .01). Corrected distance near visual acuity was 0.11 logRAD in the Lumina group and 0.41 logRAD in the control group at 12 months (P < .01).

Depth of focus was significantly higher in the Lumina group at visual acuities of 0.10, 0.20 and 0.40 logMAR (P < .01).

Contrast sensitivity was similar in both groups. – by Matt Hasson
