1. An apparatus for laser assisted eye treatment, comprising:

a laser device configured to provide focused laser radiation and having an adapter coupling port;

an adapter module comprising:

a first sub-module configured to detachably couple to the laser device at the adapter coupling port and having a contact surface for an eye, the first sub-module including a plate portion, a hose connection port at the first sub-module located at one side of the plate portion;

a second sub-module that includes an eye suction ring portion having a ring axis, and that delimits at least one suction space;

a vacuum inlet port in association with each of the at least one suction space, the vacuum inlet port located at a side of the plate portion opposite the hose connection port at the first sub-module; and

an evacuation path system configured to establish a vacuum communication connection between each of the at least one suction space and the associated vacuum inlet port, the vacuum inlet port provided at the first sub-module, the evacuation path system extending from the first sub-module to the second sub-module.

2. The apparatus of claim 1 , wherein the evacuation path system includes a hose extending from the hose connection port at the first sub-module to a hose connection port at the second sub-module.

3. The apparatus of claim 2 , wherein the hose is detachably connected to at least one of the hose connection port at the first sub-module and the hose connection port at the second sub-module.

4. The apparatus of claim 2 , wherein:

at least one of the hose connection port at the first sub-module and the hose connection port at the second sub-module is designed as a hose insert.

5. The apparatus of claim 1 , wherein:

a channel is formed in the plate portion to extend from the one side to the opposite side of the plate portion; and

the vacuum inlet port being formed by an open end portion of the channel located at the opposite side of the plate portion.

6. The apparatus of claim 1 , wherein the at least one suction space includes a suction space operable to cause the eye suction ring portion to be sucked against the eye.

7. The apparatus of claim 1 , wherein the at least one suction space includes a suction space operable to cause the first sub-module to be sucked against the second sub-module.

8. The apparatus of claim 1 , wherein:

the first and second sub-modules are held together in a module and are adjustable with respect to each other in the module between a first relative position in which the contact surface assumes a first axial position with respect to the eye suction ring portion and a second relative position in which the contact surface assumes a second axial position with respect to the eye suction ring portion;

the first axial position of the contact surface corresponds to a position in which the contact surface is still out of contact with the eye when the eye suction ring portion has been placed on the eye; and

the second axial position of the contact surface corresponds to a position in which the contact surface is in shaping contact with the eye when the eye suction ring portion is placed on the eye.

9. The apparatus of claim 8 , wherein:

the second sub-module includes a centering portion having a funnel section which tapers in a direction axially toward the eye suction ring portion;

the first sub-module includes a conical portion adapted for axial insertion into the centering portion;

the conical portion is inserted deeper into the centering portion in the second relative position of the first and second sub-modules than in the first relative position; and

the at least one suction space includes a suction space delimited at least partially by the funnel section and the conical portion.

10. An apparatus for laser assisted eye treatment, comprising:

a laser device configured to provide focused laser radiation and having an adapter coupling port;

an adapter module comprising:

a first sub-module configured to detachably couple to the laser device at the adapter coupling port and having a contact surface for an eye;

a second sub-module that includes an eye suction ring portion having a ring axis, and that delimits at least one suction space;

a vacuum inlet port in association with each of the at least one suction space; and

an evacuation path system configured to establish a vacuum communication connection between each of the at least one suction space and the associated vacuum inlet port, the vacuum inlet port provided at the first sub-module, the evacuation path system extending from the first sub-module to the second sub-module, wherein:

the adapter coupling port includes a vacuum outlet port and a slide-in structure having at least one slot adapted to slidingly receive in a sliding direction orthogonal to the ring axis a rim portion formed at the first sub-module; and

the vacuum inlet port moves into overlapping relationship with the vacuum outlet port when the first sub-module is slid into the slide-in structure.

11. The apparatus of claim 10 , wherein the vacuum outlet port is formed by a suction cap.

12. An apparatus for laser assisted eye treatment, comprising:

a laser device configured to provide focused laser radiation and having an adapter coupling port;

an adapter module comprising:

a first sub-module configured to detachably couple to the laser device at the adapter coupling port and having a contact surface for an eye;

a second sub-module that includes an eye suction ring portion having a ring axis, and that delimits at least one suction space;

a vacuum inlet port in association with each of the at least one suction space; and

an evacuation path system configured to establish a vacuum communication connection between each of the at least one suction space and the associated vacuum inlet port, the vacuum inlet port provided at the first sub-module, the evacuation path system extending from the first sub-module to the second sub-module, wherein:

the at least one suction space includes a first suction space and a second suction space;

the evacuation path system comprises:

a first hose extending from a first hose connection port at the first sub-module to a first hose connection port at the second sub-module; and

a second hose extending from a second hose connection port at the first sub-module to a second hose connection port at the second sub-module;

the first hose connection port at the second sub-module is in vacuum communication connection with the first suction space; and
