Computer-based visual cortex training beneficial after IOL surgery

The system is based on the premise that the brain plays a role in vision and that the central nervous system has neuroplasticity so that it can be trained to use the input it receives in a more effective fashion. It is an interactive program that is tailored and continuously adaptive to the participant's visual abilities. Patients work with the computer-based program in 20- to 30-minute sessions in which they are asked to locate a series of Gabor patches (specifically designed for the individual patient) presented in the visual field.

The full program involves 20 sessions that are completed over a period of about 2 months, and the task at each session becomes progressively more difficult as the stimulus pattern is changed.
