Abstract

The invention is applicable to the field of medical equipment and instruments, and discloses a laser ophthalmic surgery system based on dual-mode image adjustment. The system comprises an optical fiber oscillator, a three-dimensional galvanometer scanning unit, a spectral domain optical coherence tomography unit, a sweep frequency optical coherence tomography unit, an optical fiber coupler, an optical guide unit, an image analysis processing unit and a control unit. According to the surgery system provided by the invention, a spectral domain optical coherence tomography optical path and a sweep frequency optical coherence tomography optical path form a pair of mutual cooperation structures through an optical fiber coupler, so that high-resolution clear image information from the corneas tothe fundus retinas can be quickly acquired; and laser pulse is accurately positioned in real time, and a new surgery scheme is made according to the acquired image information, so that the surgery accuracy and safety can be improved.

Description

technical field

[0001] The invention relates to the field of medical equipment and instruments, in particular to a dual-mode image-based laser eye surgery system. Background technique

[0002] In recent years, femtosecond laser technology has been introduced into the field of medical ophthalmology. Its application principle is to use its extremely short pulse width, small light pulse energy to obtain extremely high peak power and strong focusing ability, and can be completed in biological tissues. Precise cutting.

[0003] At present, the optical coherence tomography system is used to image the internal structure of the eye tissue to guide femtosecond laser ophthalmic surgery. The optical coherence tomography technology has the characteristics of non-contact, no radiation, high detection sensitivity, and no damage. The optical coherence tomography technology has become an ophthalmic Standard technique for measuring the structure of the human eye during surgery. However, th...
