Virtual Refractive Surgery for the Prevention Of Negative Dysphotopsia (“vRESPOND”) study
vRESPOND Project Summary
The overall goal of the vRESPOND study is to provide a clinically feasible and cost-effective
Method to manage negative dysphotopsia (ND). We aim to use MRI-based patient-specific eye-models to uncover the underlying optical origin of ND through ray-tracing simulations. We subsequently aim to develop a Virtual Refractive Surgery application for the prevention and treatment of ND.
In terms of specific research aims:
- comprehensive clinical evaluation will be made of 60 ND patients and 60 pseudophakic controls both in terms of objective ophthalmic measurements and standardized questionnaires.
- Based on these data, ray-tracing analyses will be performed using the patient-specific, MRI-based, eye-models to:
- elucidate the mechanism for ND
- determine the key aspects of IOL design to prevent ND
- develop the Virtual Refractive Surgery model to preoperatively select high-risk patients and guide to the optimal IOL-type to prevent ND for these high-risk patients.
