This invention relates to a method for diagnosing keratoconus by analyzing the geometric properties of Purkinje images. The method involves capturing Purkinje images of the cornea using a low-cost and simple device, such as a smartphone attachment, making it more accessible than current diagnostic tools like slit lamps. By comparing these images to reference images from healthy corneas, significant shifts and distortions are identified as indicators of keratoconus. This non-invasive tool provides an accessible and cost-effective means for early detection and ongoing monitoring. The method's reliability is ensured through extensive data collection from both healthy and keratoconic corneas. This approach offers primary assessments, especially in areas lacking access to advanced medical care, potentially reducing the need for more invasive procedures.

This invention provides a dual-wavelength confocal superlens and its design method, as well as a photoacoustic imaging method and system, belonging to the field of optical lens technology. The invention provides a design method for a dual-wavelength confocal superlens that can use two different wavelengths of light to visualize cancer cells and normal tissues. Normal cells and cancer cells absorb energy from the two different wavelengths, causing them to heat up and expand. After cooling, they emit ultrasonic waves, which are then collected by an ultrasonic transducer. Finally, photoacoustic imaging is achieved through calculation. This invention aims to enhance photoacoustic imaging contrast while avoiding the risks of invasive procedures. The dual-wavelength design provides multiple contrast mechanisms, allowing for the comparison of various tissue features during the same imaging process, enhancing the detection capability of lesions, and effectively reducing the influence of noise in the photoacoustic signal. This invention can be applied to early cancer detection and can also be used to monitor tumor response during treatment and evaluate treatment effectiveness.
