Visual simulation of intraocular lenses: technologies and applications [Invited]

Area of Science:

• Ophthalmology
• Optical Engineering
• Visual Perception

Background:

• Intraocular lens (IOL) selection is critical for cataract surgery outcomes.
• Traditional evaluation methods lack patient-centric perceptual simulation.
• Newer IOL designs require advanced assessment tools.

Purpose of the Study:

• To introduce and evaluate visual simulators for preoperative IOL assessment.
• To demonstrate the benefits of visual simulators in patient decision-making and personalized surgery.
• To explore the role of simulators in IOL design and regulatory evaluation.

Main Methods:

• Utilizing visual simulators with dynamic optical elements (deformable mirrors, spatial light modulators, optotunable lenses).
• Simulating various IOL types, including monofocal, multifocal, and extended depth-of-focus designs.
• Replicating real-world eye optics and visual system interactions with IOLs.

Main Results:

• Visual simulators enable preoperative preview and comparison of different IOL designs.
• These tools enhance patient understanding and decision-making for personalized cataract surgery.
• Simulators can incorporate patient-reported outcomes for regulatory assessment.

Conclusions:

• Visual simulators provide realistic, patient-centered visual assessments for IOLs.
• They have the potential to transform IOL design, regulatory processes, and patient care.
• Advancements in simulators promise more successful and individualized cataract surgery outcomes.
