The present invention provides a method for capturing optical micro detectors for improved surgical handling during implantation into an eye comprising the steps of providing an optically active thin film heterostructure on a soluble substrate; forming an array comprising individual optical microdetectors from the optically active thin film heterostructure; attaching the optical microdetector array onto a biodegradable polymer carrier membrane; and separating the optical microdetector array attached to the biodegradable polymer carrier membrane from the soluble substrate thereby capturing the optical microdetectors in the bio-polymer carrier membrane for improved handling of the optical micro-detectors during transfer and implantation into the eye.

La présente invention concerne un procédé pour capturer les micro-détecteurs optiques à des fins d'une meilleure manipulation chirurgicale pendant l'implantation dans l'oeil. Le procédé consiste à créer une hétérostructure de film mince sur un substrat soluble; à former un réseau comprenant des micro-détecteurs optiques isolés destinés à une hétérostructure de film mince optiquement actif; à fixer un réseau de micro-détecteurs optiques sur une membrane de support polymère biodégradable; et à séparer le réseau de micro-détecteurs optiques attaché à la membrane de support polymère biodégradable du substrat soluble pour capturer des micro-détecteurs optiques dans la membrane de support bio-polymère pour faciliter la manipulation chirurgicale pendant le transfert et l'implantation dans l'oeil.
