Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to an artificial crystal automatic injection system.
Background
The human eye has the function of providing vision by transmitting light through a clear exterior, known as the cornea, and focusing the image on the retina through the lens. The quality of the focused image depends on many factors, including the size and shape of the eye and the transparency of the cornea and lens. When age and disease cause the lens to become less transparent, vision deteriorates because of the diminished light which can be transmitted to the retina. This defect in the lens of the eye is known medically as a cataract. An acceptable treatment for this condition is surgical removal of the lens and replacement of the lens function by an intraocular lens (IOL).
In the united states, most cataractous lenses are removed by a surgical technique called phacoemulsification. During this procedure, an opening is made in the anterior capsule and a tiny phacoemulsification cutting tip is inserted into the diseased lens and vibrated by ultrasound. The vibrating cutting tip liquefies or emulsifies the lens so that the lens may be aspirated from the eye. The diseased lens is once removed replaced with an artificial lens.
The IOL is injected into the eye through the same small incision used to remove the diseased lens. The insertion barrel of the IOL injector is loaded with an IOL and the tip of the insertion barrel is inserted into the incision to deliver the lens into the eye.
Many IOLs manufactured today are made from polymers having special properties. These properties enable the lens to be folded and unfolded into the appropriate shape when delivered into the eye. A number of manual injection devices may be used to inject these crystals into the eye. However, threaded manual syringes require the use of two hands, which is cumbersome and tedious. Syringe-type injectors produce inconsistent injection forces and displacements. Accordingly, there is a need for improved devices and methods for delivering IOLs to an eye.
