Claims (14)

An ophthalmology system,
a patient interface including a face mask having a nasal bone frame configured to hold a patient's nose in place relative to the ophthalmic system; An ophthalmic system establishes a predetermined alignment between an aperture of the ophthalmic system and an eye of a patient based on a personalized three-dimensional (3D) facial model of the patient . 2. The system of claim 1, wherein the ophthalmological system is one of an ophthalmic diagnostic system, an ophthalmic treatment system, or an ophthalmic therapeutic dispensing system. The face mask has a preconfigured shape based on the known contours of the bony areas of the patient's face and is configured to hold the patient's face in a predetermined position establishing the predetermined alignment. 3. The system of claim 1 or 2 , wherein the patient's face is in the predetermined position when the number of pressure points created by the face mask is minimized . 4. A system according to any preceding claim, wherein the face mask is 3D printed. The 3D facial model may be produced using one of the following techniques: laser triangulation 3D scanning techniques, structured light 3D scanning techniques, touch-based 3D scanning techniques, time-of-flight 3D scanning techniques , photogrammetry, depth-sensing cameras, and multi-camera imaging systems. 5. A system according to any one of claims 1 to 4 , obtained by the use of one or more 3D imaging devices . the 3D facial model is obtained using a mechanical scanning system that includes an array of contact probes ;
Claims 1 to 4, wherein the touch probe is displaced in response to a patient pushing his or her face into the mechanical scanning system, and wherein the displaced position of the touch probe defines a height map stored in an electronic memory . The system according to any one of the following . the face mask includes an array of contact probes covered with a flexible material forming a surface of the mask, displacement of the contact probes defining the contour of the face mask ;
4. A system according to any preceding claim, wherein the selected contact probe is moved to a target position defining a face mask shape according to a selected height map stored in an electronic memory and corresponding to the patient . The electronic memory stores a plurality of probe height maps for a plurality of different patients , and the face mask moves a selected contact probe to a corresponding target position of the selected contact probe according to the stored probe height map for a selected patient. 8. The system of claim 7 , wherein the system is configurable for any selected patient selected from the plurality of different patients by moving the system. The ophthalmic system includes an ophthalmic device and a connector coupling the face mask to the ophthalmic device;
The connectors can be used in tonometers, therapeutic drug dispensers, fundus imaging systems, optical coherence tomography systems, optical coherence tomography angiography systems, biometric systems, refractors, visual field testers, surgical devices, ophthalmic lasers, and wavefront sensors. 9. A system according to any preceding claim, adapted to receive a plurality of different types of ophthalmic devices, including one or more of: 10. A system according to any preceding claim, wherein the face mask is a partial face mask that does not surround the patient's eye sockets . The ophthalmological system includes a fundus imaging system, an optical coherence tomography system, an optical coherence tomography angiography system, a biometric system, a refractor, a visual field tester, a wavefront sensor, a tonometer, a surgical device, an ophthalmic laser, and a therapeutic drug dispensing system. 11. A system according to any preceding claim, comprising one or more of the containers. 12. A system according to any preceding claim, wherein the face mask includes a light shield forming a light-tight enclosure that shields the eyes from ambient light. The system according to any one of claims 1 to 12, wherein the predetermined alignment between the aperture of the ophthalmological system and the patient's eye is established within a tenth of a millimeter in 3D space. . the aperture of the ophthalmological system is divided into an illumination portion defining an area through which light entering the eye passes and a collection portion through which light exiting the eye is collected for imaging;
14. A system according to any preceding claim, wherein the eye is aligned to these parts of the aperture.
