This study will examine the history of video game use an activities of manual dexterity with the scored skills used in the Eyesi surgical simulator. Subjects will be asked to participate in video games or no video games prior to testing skills in Eyesi to examine training effects of video game participation and changes in manual dexterity.

A popular crossover fighting video game released in 2001 for the Nintendo Gamecube that emphasizes reflexes and dexterity to perform specific maneuvers will be used in this study as a potential dexterity trainer.

The Eyesi is a training device utilized in many ophthalmology residency training programs to improve intraocular operative skills. The EyeSi is a validated training tool that uses high-end virtual reality that can be equipped with instrumentation for cataract or vitreoretinal surgery. The device itself consists of eyepieces that replicate a surgical scope, a mannequin head where handpiece probes can be inserted and position tracked to virtually recreate a surgical environment. The simulator also has a monitor that can be used to see the surgical simulator environment. As part of the software, numerous training tasks and exercises are available programmed into the device. These exercises utilize numerous metrics such as distance traveled, tissue treatment, efficiency, instrument handing, and others to provide the user with a raw score out of 100 for each task.

Subjects will then be asked to complete a manual dexterity questionnaire including history of video game use as well as tasks demonstrating manual dexterity ability such as the ability to play a musical instrument. Participants will then be randomized to the intervention group or the control group.

The intervention group will be asked to play 10 minutes of the Gamecube game "Super Smash Brothers Melee" as their "warm-up" prior to completing the EyeSi surgical tasks of navigation, forceps, and bimanual with their scores collected and averaged across all tasks.

The control group will complete the EyeSi surgical tasks of navigation, forceps, and bimanual with their scores collected and averaged, but will not perform a "warm-up" task.

Planned statistical analysis will include an average of total scores across navigation, forceps, and bimanual tasks. Chi square analysis will then be utilized to determine any statistical significance between intervention and control groups. Simulator scores will also be associated with questionnaire responses and simple linear regression will be used for analysis.

Inclusion Criteria:

• UTMB Medical student volunteers who respond to email invitation to participate
• 18-40 years of age inclusive

Exclusion Criteria:

• Prior experience with EyeSi surgical simulator
• Not a UTMB Medical Student
• Not between 18-40 years of age inclusive

Data will be assigned a unique participant identification number and no personal information will be collected as part of the data set. Information from the questionnaire and study tasks will be associated with your subject identification number not any personal identifiers. Your participation or lack of participation will not be made known to any individuals outside of the study personnel with which you interface and will also be unavailable to any faculty within the UTMB Ophthalmology program to ensure that there is no risk in participation affecting future departmental relationships, evaluations or considerations.
