Evaluation of extended depth-of-focus hydrophobic intraocular lens with an optic concept based on combination of...

Extended depth-of-focus (EDOF) intraocular lenses (IOLs) provide a continuous range of uncorrected vision at different distances.

To assess visual acuity, refractive outcomes, and patient satisfaction after cataract surgery using the LuxSmart EDOF IOL (Bausch+Lomb).

A two-center, prospective observational clinical study.

This study includes patients who have undergone bilateral phacoemulsification with bilateral implantation of the LuxSmart EDOF IOL, with the aim of achieving emmetropia. Visual acuity (VA) and subjective refraction were obtained in all patients preoperatively and at 1 week, 1 month, 3 months, and 6 months postoperatively. Subjective measures were obtained using the Catquest-9SF questionnaire and the Patient-Reported Spectacle Independence Questionnaire (PRSIQ). Contrast sensitivity and a glare assessment were undertaken postoperatively. Safety outcomes were additionally assessed.

Sixty eyes from thirty patients were recruited for this study. The mean spherical equivalent was 1.04 ± 1.67 D preoperatively and -0.30 ± 0.46 D at 6 months. Monocular uncorrected distance VA was 0.57 ± 0.32 (logMAR) preoperatively and 0.09 ± 0.12 (logMAR) at 6 months. Mean 6-month monocular uncorrected VA was 0.11 ± 0.13, 0.12 ± 0.15, and 0.31 ± 0.15 (logMAR) at 80, 66, and 40 cm, respectively. More than 90% of patients were either fairly or very satisfied with their vision. There was one case of suspected vitreomacular traction postoperatively.

The LuxSmart EDOF IOL offers good refractive, VA, and safety outcomes. The single elongated focal point designed to enhance the DOF shows good results for VA and patient satisfaction.
