Visual Performance Of An Extended Depth-Of-Focus Intraocular Lens In Patients With Cataract

To investigate the visual performance after implantation of an extended depth-of-focus intraocular lens (IOL) in patients with senile cataract.

Eighty-three eyes from 45 patients were recruited for this prospective interventional study. Bilateral phacoemulsification with LuxSmart IOL (Bausch & Lomb) implantation was performed in healthy patients with senile cataract with the aim of achieving emmetropia. Uncorrected and corrected visual acuity at distance, intermediate, and near, as well as the spherical equivalent in manifest refraction were measured at 1 week, 1 month and 3 months. Glare, spectacle dependence, and satisfaction were recorded 3 months after the surgery with Visual Function Index and modified Visual Function Index questionnaire.

All surgeries were uneventful. At 3 months the mean spherical equivalent was -0.11 ± 0.46 D, while monocular and binocular UDVA was 0.84 ± 0.14 (Snellen) and 0.94 ± 0.11 (Snellen) respectively. Mean 3-month monocular uncorrected VA was 0.54 ± 0.14, and 0.69 ± 0.11 (M notation) at 66, and 30 cm respectively, while binocular uncorrected VA was 0.48 ± 0.13, and 0.62 ± 0.15 (M notation) at 66, and 30 cm respectively, More than 90% of patients were either fairly or very satisfied with their vision. There were two cases of postoperative Irving-Gass syndrome that resolved by 3 months.

The LuxSmart EDOF IOL offers good refractive, VA, and safety outcomes. The single elongated focal point designed to enhance the DOF shows satisfactory results for VA under various conditions and patient satisfaction is high in great majority of cases.
