Abstract
The present disclosure provides a one-piece patient interface for single-stage docking of a femtosecond laser. The one-piece patient interface includes an upper circular portion, a lower conical portion integrally formed with the upper circular portion, an applanation plate in the lower conical portion, and a vacuum connection. The applanation plate may be at least partially coated with an applanation plate coating that is substantially transparent to treatment wavelengths of the femtosecond laser and substantially reflective to non-treatment wavelengths. The disclosure further provides a method for single-stage docking of a femtosecond laser and a system for cutting a flap on an eye using a femtosecond laser.
Claims15
A one-piece patient interface for single-stage docking of a femtosecond laser, the one-piece patient interface comprising:
- an upper circular portion;
- a lower conical portion integrally formed with the upper circular portion;
- an applanation plate in the lower conical portion;
- and
- a vacuum connection.
A method for single-stage docking of a femtosecond laser comprising:
- connecting a vacuum to a vacuum connection of a one-piece patient interface, the patient interface comprising:
- an upper circular portion;
- a lower conical portion integrally formed with the upper circular portion;
- an applanation plate in the lower conical portion;
- and
- the vacuum connection;
- connecting a femtosecond laser to the one-piece patient interface;
- positioning the one-piece patient interface on an eye;
- and
- activating the vacuum to hold the patient interface in contact with the eye and to applanate the eye.
A system for cutting a flap on an eye using a femtosecond laser, the system comprising:
- a femtosecond laser operable to supply a treatment wavelength;
- a control device operable to adjust a position of the femtosecond laser;
- a one-piece patient interface on an eye, the patient interface comprising:
- an upper circular portion;
- a lower conical portion integrally formed with the upper circular portion;
- an applanation plate in the lower conical portion, the applanation plate coated with an applanation plate coating that is substantially transparent to treatment wavelengths of a femtosecond laser and substantially reflective to non-treatment wavelengths;
- and
- a vacuum connection;
- a detection device operable to detect reflected non-treatment wavelengths and generate data relating to the reflected non-treatment wavelengths detected;
- and
- a processor operable to:
- receive data from the detection device relating to the reflected non-treatment wavelengths detected;
- and
- generate measurements for cutting a flap using treatment wavelengths of the femtosecond laser.
