Contact lens and ophthalmic treatment device having same
A contact lens, according to the present invention, comprises: a housing having a light-incident part on which a therapeutic beam oscillated from a beam generation part is incident, and a light-emitting part for guiding the therapeutic beam incident from the light-incident part to an eyeball; a first sensing part arranged between the light-incident part and the light-emitting part so as to sense the reaction occurring in a healing site of the eyeball on which the therapeutic beam is irradiated; and a second sensing part arranged in a region of the light-emitting part spaced from the first sensing part so as to sense whether contact has been made with the eyeball.
1. A contact lens for guiding a treatment beam directed from a beam generator to a retina of an eye, the contact lens comprising:
a housing including an entrance part through which the treatment beam directed from the beam generator enters and an exit part through which the treatment beam entering through the entrance part is guided to the eye;
a first detecting part located in the housing between the entrance part and the exit part and detecting a reaction in a treated area of the retina while the treatment beam is delivered to the treated area so as to control treatment beam radiation during the delivery of the treatment beam; and
a second detecting part located in the area of the exit part, spaced apart from the first detecting part, and detecting whether there is contact with the eye.
2. A contact lens for guiding a treatment beam directed from a beam generator to a retina of an eye, the contact lens comprising:
a first housing including an entrance part through which the treatment beam directed from the beam generator enters;
a second housing detachably attached to an opening area opposite to the entrance part of the first housing and including an exit part through which the treatment beam entering through the entrance part exits;
a first detecting part located in either the first housing or the second housing and detecting a reaction in a treated area of the retina while the treatment beam is delivered to the treated area so as to control treatment beam radiation during the delivery of the treatment beam; and
a second detecting part located in the area of the exit part and detecting whether there is contact between the second housing and the eye.
3. The contact lens of claim 2 , wherein the first detecting part is located inside the second housing, spaced apart from the second detecting part.
4. The contact lens of claim 3 , wherein the first detecting part detects an amount of bubbles in the treated area of the retina, generated by the delivery of the treatment beam.
5. The contact lens of claim 2 , wherein the operation of the beam generator is controlled in response to a detection signal from the second detecting part.
6. The contact lens of claim 2 , wherein one of the first or second housings comprises hooks, and the other housing comprises hook joints that engage with the hooks to detachably hold the first housing and the second housing together.
7. The contact lens of claim 2 , wherein the first housing and the second housing are detachably held together by either screwing or pinning.
8. The contact lens of claim 2 , wherein the first detecting part and the second detecting part comprises an ultrasonic sensor and a proximity sensor, respectively.
9. The contact lens of claim 2 , further comprising a gaze part that is located in an inner region visible to the eye and that emits gaze fixation light for a patient to look at that forms a point of gaze to prevent the eye from moving.
