Problems solved by technology

[0005] The existing corneal surgery process is mainly judged by doctors based on preoperative testing data and clinical experience. The surgical process lacks an accurate monitoring system, and the lack of a corresponding safety monitoring system will also bring risks during the surgical process.

Abstract

The invention discloses a corneal surgery safety monitoring system. A corneal topographic map instrument collects corneal topographic map data of a patient; a cornea OCT thickness gauge collects cornea thickness data of the patient; a confocal microscope collects images of corneal endothelium and retinal nerves of the patient; a data processing and monitoring system performs postoperative prediction according to the preoperative data and the operation type to obtain the corneal thickness and diopter after the ideal corneal operation, and plans the ideal topographic map change process in the operation process and the safety range of each detection parameter in the operation; a cornea three-dimensional solid model is established by utilizing data collected in real time during operation, thecornea three-dimensional solid model is compared with a planned process, and operation safety warning information is output when a comparison result does not meet a planned safety range. The system iscombined with preoperative prediction to monitor the real-time change of a corneal topographic map in an operation, can reliably monitor whether the corneal operation process is in a safe and controllable range or not, and also has an auxiliary judgment effect on doctor operation.

Description

technical field [0001] The invention relates to a corneal operation safety monitoring system. Background technique [0002] The cornea is a transparent tissue at the front of the eyeball, which plays an important role in the eye. It contributes more than 60% to the refractive power of the eyeball system. Changes in the shape of the cornea can cause significant changes in vision. Myopia, hyperopia, astigmatism and keratoconus are all ophthalmic diseases involving changes in the ocular system. By changing the refractive power of the cornea, the disease can be alleviated and the vision can be improved to a certain extent. [0003] Corneal collagen cross-linking is the latest keratoplasty technology applied clinically at the beginning of the 21st century. Riboflavin is used as a photosensitizer to locally irradiate the cornea with 370nm ultraviolet rays to increase the hardness of the cornea. Corneal cross-linking has been gradually carried out in China in recent years, and it ...
