Title: Innovations by James F Freeman
Introduction
James F Freeman is a notable inventor based in Memphis, TN (US). He has made significant contributions to the field of eye surgery technology, holding a total of 6 patents. His work focuses on enhancing the precision and effectiveness of laser refractive eye surgery.
Latest Patents
One of his latest patents is a "System to automatically detect eye corneal striae." This automated detection system is designed for use with refractive laser systems. It includes a cornea illuminator, a video camera interface, a computer, and a video display that shows possible eye corneal striae to the surgeon. The computer controls the corneal illuminator and uses a video frame grabber to extract images of the eye cornea. It is programmed to detect and recognize eye corneal striae, determining their location and analyzing their shape. After detection, the results are displayed for the surgeon, who can then decide whether to refloat, adjust, or smooth the corneal LASIK flap.
Another significant patent is the "Control system for high resolution high speed digital micromirror device for laser refractive eye surgery." This system includes a laser for producing a beam capable of making refractive corrections, an optical system for shaping the laser beam, and a digital micromirror device (DMD) for reflecting the beam toward the eye. The computer system controls the mirrors of the DMD and includes software that allows the DMD to emulate patterns and laser beam control from previous systems. This innovation can be coupled with data from corneal topographers or wavefront sensor systems, enhancing the quality of correction beyond prior methods.
