Comparison Of Visual Results And Optical Quality Of Two Presbyopia-Correcting Intraocular Lenses: Tecnis Symfony Versus Tecnis Synergy

This study compared the extended depth of focus (EDOF) intraocular lens (IOL) (ZXR00; Tecnis^® Symfony^®, Johnson & Johnson Vision, Santa Ana, CA, USA) and a new presbyopia-correcting IOL that combines EDOF and multifocal profiles (ZFR00; Tecnis^® Synergy^®, Johnson & Johnson Vision, Santa Ana, CA, USA) with the same material.

The medical records of patients undergoing cataract surgery with ZXR00 or ZFR00 implantation between March 2021 and July 2021 and with the data available for the 3-month visit were reviewed. The uncorrected near, intermediate, and distance visual acuity (VA), corrected distance VA, defocus curves, refractive errors (RE), optical quality parameters, and patient-reported visual performance parameters were the main outcome measures. 

 

Among the twenty-three enrolled patients, twelve patients (21 eyes) received ZXR00 and nine patients (17 eyes) received ZFR00. The mean age of the patients was 59.6 ± 10.6 (range: 49 to 70) and 65.2 ± 8.2 (range: 45 to 82) years in ZXR00 and ZFR00 groups, respectively, without significant difference. There was no significant difference between the two groups in terms of baseline parameters and postoperative RE. The ZFR00 group showed markedly superior intermediate and near VA (p < 0.001 for all) at 3 months postoperatively. Regarding the optical quality and visual performance parameters reported by the patient, ZXR00 was significantly better than ZFR00 (p < 0.001). 

 

 

Both IOLs had comparable distance VA. ZFR00 IOL was superior for intermediate and near visual acuity, but ZXR00 IOL was better for optical quality. Research with more participants is needed to support this finding.
