An eye fixation training device

technical field

The utility model belongs to the technical field of medical equipment, in particular to an eye fixation training device.

Background technique

With the continuous development of ophthalmic surgery technology, common cataract surgery, corneal refractive surgery, pterygium excision surgery and other ophthalmic surgery are mostly performed under topical anesthesia. The success of ophthalmic surgery depends not only on advanced equipment and skilled operation techniques of surgeons In addition, the patient's good intraoperative cooperation is required, especially during cataract surgery and corneal refractive surgery, the patient's eyes need to be fixed. However, for patients, fear and anxiety of surgery are unavoidable, which affects the degree of cooperation in fixation during surgery. Therefore, fixation training is usually performed before ophthalmic surgery. During fixation training, the patient exposes the eyeball, fixes the eye on a certain point, and keeps it for a certain period of time.

Common vision fixation training, the patient covers one eye with one hand, makes a fist with the other hand and stretches out the index finger, places the index finger directly in front of the other eye, fixes the eyes on the index finger, and performs the other eye after staring for a certain period of time. Eye training, fixation training for both eyes alternately. There are also existing technologies that use fixation training devices for training, but no matter whether it is the index finger fixation training method or the fixation training device, there is a lack of training timing. The timing of switching between the two eyes alternate training depends on the patient's subjective judgment, and there may be one eye. When there is not enough time for fixation training, switch to the other eye for fixation training. For example, during the fixation training before laser correction surgery for myopia, the eyes usually keep fixation for about 1 minute. If the time for fixation training is not enough, It is easy to cause poor eye fixation training effect.
