A newly filed patent (Publication Number: US20240032787A1) describes an innovative ophthalmic apparatus designed to enhance the accuracy and efficiency of eye examinations. The apparatus includes an optical system with both illumination and imaging components, a movement mechanism to adjust the position of the subject's eye and the optical system, and a controller circuit to regulate these movements. The controller is programmed to optimize the amount of light passing through the imaging aperture based on the corneal curvature radius and the distance between the corneal apex position and the imaging aperture conjugate position. Additionally, the apparatus features processing circuitry for alignment reference position identification, corneal apex position identification, corneal reflection image position identification, determination of flare state based on fundus image, and user interface control.

Furthermore, the patent details a method for controlling the ophthalmic apparatus, involving precise adjustments to the imaging aperture movement mechanism based on corneal curvature radius, corneal apex position, and corneal reflection image position. The method also includes steps for identifying alignment reference positions, determining flare state, and utilizing user interface controls. By implementing these advanced control mechanisms, the ophthalmic apparatus aims to provide accurate and reliable eye examinations, ensuring optimal imaging quality and diagnostic outcomes. The patent also includes provisions for computer-readable recording mediums containing programs to execute the method steps outlined in the patent, emphasizing the potential for automation and digital integration in ophthalmic practices.
