endoscopy
Biophotonics• procedures and devices that use light technologies
• minimally invasive
• fewer complications
• less discomfort
Biophotonics: Endoscopes• help physicians see inside the body
• help perform surgeries without big incisions
Biophotonics: Endoscopes
Endoscopic surgery Traditional surgery
Biophotonics: Laser Eye Surgery• a high energy laser is used to take a tiny slice off the front of the cornea
• corrects near-sightedness
