Abstract

The invention relates to an ophthalmostat for all-femtosecond SMILE (small incision lenticule extraction) surgery. The ophthalmostat comprises a handle, a connecting rod and a fixing ring. The handle comprises a handheld part coaxially made; one end of the handle is obliquely fixed to one side of the fixing ring through the connecting rod; a circular plane of the fixing ring is oblique to the handle; center lines of the handle, the connecting rod and the fixing ring are coplanar. The ophthalmostat can effectively immobilize an eyeball during separation of the corneal stroma lens, allowing surgeons to conveniently operate by both hands in cooperation; a certain acting point can be given to the hand separating the lens, along the radial line of the eyeball; the separation is made smoother and more effective; handle is clearer; success rate of complete extraction of the corneal stroma lens can be increased, and surgical complications such as lens residue and fracture are decreased.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to microsurgical instruments related to corneal refractive surgery, in particular to an eyeball fixator for full femtosecond SMILE surgery. Background technique [0002] In recent years, with the application of femtosecond laser, corneal refractive surgery has entered a new stage of development. With its precise cutting, good safety and predictability, femtosecond laser brings corneal refractive surgery into a new era. In recent years, the emergence of femtosecond laser small incision lenticule extraction (SMILE) has achieved a major breakthrough in surgical design concepts. There is no corneal flap production in this operation, which avoids a series of surgical complications caused by corneal flap production, and also avoids postoperative safety hazards such as corneal flap displacement and biomechanical stability caused by trauma after surgery. The use of femtosecond l...
