Comparative Evaluation of Visual Performance and Patient Satisfaction following Cataract Surgery: A Retrospective Analysis of an Extended Depth-of-Focus Intraocular Lens and a Diffractive Multifocal Lens with Extended Depth of Focus.

(1)

Background

Cataract surgery has evolved significantly with the development of multifocal and extended depth-of-focus intraocular lenses (IOLs), driven by increasing patient desire for spectacle independence. (2)

Methods

This retrospective, single-center study conducted on 86 eyes from 59 patients aged 40-80 years compared the performance and patient satisfaction of Symfony® and Synergy® (Johnson & Johnson Vision) IOLs during a follow-up of 1 year postsurgery. Uncorrected and corrected distance, intermediate, and near visual acuities were assessed (UDVA, CDVA, UIVA, CIVA, UNVA, and CNVA, respectively). (3)

Results

Although both IOLs demonstrated a commendable distance VA, Synergy® outperformed in near VA (UNVA, p = 0.040; CNVA, p = 0.014), and Symfony® slightly excelled in intermediate VA (UIVA, p = 0.014; CIVA, p = 0.040). The defocus curve of Synergy® maintained a higher VA even at -4 D with a smoother curve and a broad landing zone. Although the optical quality assessments were similar, Symfony® had a nonsignificant edge. Patients indicated higher satisfaction and reduced reliance on spectacles with Synergy® despite more frequent reports of glare and halos. (4)

Conclusions

These findings highlight the importance of personalized IOL selection in cataract surgery, which must be customized to apply the distinctive advantages of each IOL to address the unique visual requirements and lifestyle of patients.
