Abstract: An imaging tool with a tubular implement of minimal diameter for locating in a patient's eye and to extend an image capturing platform therefrom. The platform is uniquely sized for storage within the lumen or inner diameter of the implement, such as a thin film image sensor. However, a microchip package having a bulk footprint too large for the inner diameter of the implement may be displaced to another location of the tool such as within the adjacent, more sizeable handpiece or housing. Further, the platform may be expanded upon being exposed to the interior of the eye by the extending thereinto. Thus, an increased surface and pixel count may be provided for the imaging.
