Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To address this gap, a virtual reality-based approach is proposed to simulate daily activities and assess visual performance. This innovative method can provide insights into how multifocal IOLs enhance activities requiring good binocular vision at varying distances, a capability monofocal IOLs may lack. A randomized clinical trial is suggested to compare the TECNIS Synergy multi-focal IOL with the TECNIS monofocal IOL in monovision. Unlike its bifocal predecessors, the TECNIS Synergy IOL is trifocal, providing clear vision at near, intermediate, and far distances. The hypothesis is that patients implanted with the TECNIS Synergy IOL will demonstrate superior visual performance in simulated day and night conditions compared to those implanted with monofocal IOLs and monovision.
