Computer-based visual cortex training beneficial after IOL surgery

October 15, 2011

Experience with a commercially available computer-based visual cortex training system indicates it is a useful option to consider for improving outcomes of patients with complaints about visual acuity and quality after premium 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.
