This model can restore visual function and provide good intermediate and near vision in both photopic and mesopic conditions.
Researchers in Portugal evaluated the TECNIS Synergy ZFR00V intraocular lens (IOL) (Johnson & Johnson Vision), a new hybrid presbyopia-correcting model, and found good visual function in photopic and mesopic conditions and high patient satisfaction following cataract surgery, according to Filomena Ribeiro, MD, PhD, FEBO from the Hospital da Luz Lisbon, Lisbon University, and the Visual Sciences Research Centre, Lisbon, and coworkers.
Ribeiro and colleagues evaluated the IOL in the Hospital da Luz Lisboa to determine the clinical outcomes in a prospective observational study.1 All 27 study patients underwent bilateral IOL implantation. The visual acuity (VA) levels at distance, intermediate (66 cm), and near (40 cm) were measured under photopic and mesopic conditions.
The patients also completed a questionnaire at 3 months postoperatively to determine their spectacle independence and satisfaction with the IOL results. The investigators also obtained the defocus curve for binocular vision.
The investigators reported that under photopic conditions, the corrected distance VA (CDVA) was −0.02 ± 0.07, the distance-corrected intermediate VA was 0.03 ± 0.11, and the distance-corrected near VA (DCNVA) was 0.00 ± 0.08. Under mesopic conditions, the CDVA was −0.01 ± 0.05 and the DCNVA was 0.07 ± 0.09.
The binocular defocus curve showed that the mean VA exceeded 0.30 logarithm of the minimum angle of resolution (logMAR) within the +1.00 to −4.00 diopter (D) interval, and the VA exceeded 0.10 logMAR between +0.50 and −3.00 D.
All patients were spectacle independent at distance and 3.7% of reported using spectacles in some intermediate/near vision scenarios. As much as 88% of the patients reported being fairly satisfied or very satisfied.
Investigators concluded that this IOL model, when used during cataract surgery, can restore visual function and provide very good intermediate and near vision in both photopic and mesopic conditions, resulting in a high level of patient satisfaction.
