Summary

The proposed randomized clinical trial aims to compare visual performance, measured using VR simulations, in cataract patients implanted either with bilateral trifocal IOL or bilateral monofocal IOL with monovision. The hypothesis is that patients implanted with trifocal IOL would exhibit superior visual performance, in both daytime and nighttime conditions, compared to those with a monofocal IOL with monovision.

Detailed description

Cataract surgery provides an opportunity to restore the quality of life by improving vision. While monofocal intraocular lenses (IOLs) implantation with monovision has been a common approach for cataract surgery, it may result in limited clarity at the intermediate distance and reduced depth perception. The advent of multifocal IOLs has expanded the possibilities, potentially offering increased visual performance in different ranges of vision. However, the benefits of multifocal IOLs in everyday activities are not fully understood due to the lack of task-based investigations. 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.
