Abstract

An ophthalmic docking system is presented that can reduce a condensation of a patient interface of a surgical laser system. The ophthalmic docking system includes a patient interface that has a proximal portion configured to be attached to an ophthalmic system, a distal portion configured to be attached to an eye that includes a contact lens and an interface attachment system; and a decondenser, coupled to the patient interface and configured to reduce a vapor condensation on the contact lens.

Claims (44)

1. An ophthalmic docking system, comprising:

a patient interface, having

a proximal portion configured to be attached to an ophthalmic system,

a distal portion configured to be attached to an eye, comprising

a contact lens, and

an interface attachment system;

a decondenser, coupled to the patient interface and configured to reduce a vapor condensation on the contact lens;

a vacuum-suction ring, configured to form a sealable coupling when attached to the eye; and

a vacuum-hose, configured to couple a vacuum-suction pump and the vacuum-suction ring to transfer a vacuum suction, generated by the vacuum-suction pump, to the vacuum-suction ring to create the sealed coupling between the vacuum-suction ring and the eye, thereby attaching the patient interface to the eye.

2. The ophthalmic docking system of claim 1 , the decondenser comprising:

an air pump, configured to pump air towards the interface attachment system.

3. The ophthalmic docking system of claim 2 , the decondenser comprising:

at least one of a gas container and a reservoir, configured

to store high-pressure air pumped by the air pump at a pressure higher than an ambient pressure, and

to forward the high-pressure air towards the interface attachment system.

4. The ophthalmic docking system of claim 3 , the decondenser comprising:

a pressure-regulator, coupled to the reservoir and configured to forward the high-pressure air towards the interface attachment system with a pressure fluctuation smaller than a pressure fluctuation of the high-pressure air pumped by the air pump to the reservoir.

5. The ophthalmic docking system of claim 1 , the decondenser comprising:

a dehumidifier, configured to reduce a vapor content of an airflow directed towards the interface attachment system.

6. The ophthalmic docking system of claim 1 , the decondenser comprising:

an air-heater, configured to increase a temperature of an airflow directed towards the interface attachment system.

7. The ophthalmic docking system of claim 1 , wherein:

the decondenser is coupled to the vacuum-suction ring via a decondenser-hose.

8. The ophthalmic docking system of claim 1 , wherein:

the ophthalmic docking system comprises a valve, coupled to the vacuum-suction ring; and

the vacuum-hose and the decondenser-hose are coupled to the vacuum-suction ring through the valve, wherein the valve is capable of switching between a first fluid communication channel coupling the vacuum-pump and the vacuum-suction ring and a second fluid communication channel coupling the decondenser and the vacuum-suction ring.

9. The ophthalmic docking system of claim 1 , wherein:

the interface attachment system comprises a vacuum-suction ring;

the ophthalmic docking system comprises a valve, coupled to the vacuum-suction ring and the decondenser; and

the decondenser comprises an air pump, wherein

the valve is capable of switching between a first fluid communication channel coupling an air-intake port of the air pump and the vacuum-suction ring, and a second fluid communication channel coupling an air-output port of the air pump and the vacuum-suction ring.

10. The ophthalmic docking system of claim 1 , wherein:

the interface attachment system comprises a vacuum-suction ring, configured to partially define a toroidal volume when attached to the eye; and

the decondenser comprises an air pump, coupled to the vacuum-suction ring by a vacuum-decondenser-hose, wherein

an operation of the air pump can be switched between a first mode to apply pumped air for the contact lens through the vacuum-decondenser-hose, and a second mode to apply vacuum suction to the vacuum-suction ring through the vacuum-decondenser-hose.

11. The ophthalmic docking system of claim 1 , wherein:

the decondenser is configured to heat the contact lens on a side that does not contact the eye.

12. The ophthalmic docking system of claim 1 , the decondenser comprising:

an electric heater or a radiative heater.

13. The ophthalmic docking system of claim 1 , wherein:

the proximal portion and the distal portion are separate elements; and

the proximal portion and the distal portion can be coupled together after the distal portion has been attached to the eye.

14. The ophthalmic docking system of claim 1 , the distal portion comprising:

a grip system, configured to assist the mechanical fastening of the patient interface to the eye.
