Zusammenfassung:	The utility model relates to a cutting lathe for ophthalmology. A jetting nozzle is arranged in a lathe spindle and connected with a refrigeration source; refrigerant can directly reach the cavity of a lathe chuck to cause the temperature of the chuck to drop down quickly; so, corneas become cool and hard; on one hand, the utility model can be stuck to the surface of the chuck in order to cut, and on the other hand, the cut effect can be guaranteed. The utility model has the advantages that the design is artful, the cornea fixing is favorable, the corneas have on injury, the machining characteristics of material can be improved, the soft cutting is changed to the rigid cutting, and the operation process is simple and easy to learn; the utility model is suitable for the lens cutting to corneal tissues and also for other freezing cutting occasions.
