Description

An ultrasonic anterior capsule crusher

technical field

The invention relates to the field of ophthalmology detection, in particular to an ultrasonic anterior capsule pulverizer.

Background technique

From an anatomical point of view, the lens is composed of anterior capsule, cortex, nucleus, and posterior capsule, and the phenomenon of opacity in these components is cataract. Cataract is an adult disease with a dramatic increase in development and a marked increase in opacity in people over the age of 60, and it is the most common disease leading to blindness.

The only treatment for cataracts is surgery to remove the cloudy lens and insert an artificial, clear intraocular lens in its place. At present, the most widely used method in cataract surgery is the method of intracapsular intraocular lens insertion after phacoemulsification. The first step is to cut the anterior lens capsule, and take out the lens by forming an incision. The size of the incision in the anterior lens capsule is a test of the level of surgery. If the incision in the anterior lens capsule is too large, the lens will fall off and cause medical accidents; If the incision of the anterior lens capsule is too small, the anterior lens capsule will atrophy and cause poor vision. Therefore, the standard incision size requires a higher level of surgical operation.
