PURPOSE:

To compare visual acuities from distance to near and patient-reported outcomes of a new hydrophobic acrylic refractive Full Range of Vision(FRoV) intraocular lens(IOL) (LuxLife Bausch+ Lomb(study group)) with that of its monofocal parent IOL (LuxGood IOL, Bausch+ Lomb(control group)) in patients undergoing bilateral cataract surgery.

METHODS:

In this multicenter, prospective, open-label study conducted at seven sites in Spain and Czech Republic, cataract patients(50 years or older) with no ocular comorbidity and maximum preoperative corneal astigmatism of 1.0 D were included. Patients were assigned in a 2:1 ratio to undergo bilateral implantation with LuxLife(N=121) or LuxGood IOLs(N=61). Patients were followed up through months. Outcome measures included binocular CDVA at 4 m, DCIVA at 66 cm, DCNVA at 40 cm(in logMAR), binocular defocus curve, Halos and Glare through a simulator, Patient- Reported Spectacle Independence Questionnaire(PRSIQ) and quality of life and overall satisfaction using the CatQuest-9SF.

RESULTS:

Postoperative binocular CDVA was 20.2 logMAR in 100% in both groups, -0.01+0.07 (study) and(control). LuxLife group had a significantly better DCIVA and DCNVA, 3 and 4 lines respectively. Binocular defocus curve showed an extended range of vision of 3.2 D(study group) and 1.45 D(control group) at 0.2 logMAR. A higher percentage of patients in the study group(81% vs 13%) were spectacle-free at all distances. A statistically significantly higher percentage of patients in the study group(ps0.001) reported no difficulty in reading newspapers(83% vs. 47%) or reading price tags(84% vs. 53%). There were no statistically significant differences between groups in Halo and Glare.

CONCLUSION:

Compared to monofocal parent LuxGood, LuxLife demonstrated superior binocular DCIVA and DCNVA; 80% of the patients implanted bilaterally with the LuxLife IOL were fully spectacle-independent at all distances. LuxLife provided a continuous Full range Of depth of Field(ROF) of 3.2D at 0.2 logMAR without being restricted by photic phenomena.
