Method of treating the human eye with a wavefront sensor-based ophthalmic instrument
View Patent ↗An improved method for treating the eye includes the step of providing an ophthalmic instrument including an integral wavefront sensor. The wavefront sensor measures phase aberrations in reflections directed thereto to characterize aberrations of the eye. The wavefront sensor may be operably coupled to a display device, which displays a graphical representation of the aberrations of the eye. Such graphical representation may include: two dimensional contour maps that graphically depict contribution of pre-specified terms (such as spherical aberration, astigmatism and coma) for the aberrations of the eye, coefficients corresponding to such pre-specified terms that characterize the aberrations of the eye, or predefined two-dimensional icons that provide a general graphical depiction of such pre-specified terms. Such graphical representations provide the practitioner with valuable information characterizing the high order optical errors of the eye (which is far beyond the diopter information typically provided by current ophthalmic instruments) for use in diagnosis and treatment of abnormalities and disease in the eye. In addition, the wavefront sensor may be part of an adaptive optical subsystem that compensates for the phase aberrations measured therein to provide phase-aligned images of the eye for capture by an image capture subsystem. Such images may be used by practitioner in diagnosis and treatment of abnormalities and disease in the eye.
1. A system for examining, diagnosing and treating abnormalities in the human eye, said system comprising:
an ophthalmic imaging instrument having an integral adaptive optical subsystem disposed along the optical axis therein, and wherein the optical axis of the ophthalmic instrument is aligned with an eye of a patient;
a light source for illuminating the eye with light produced from said light source and enabling said adaptive optical subsystem to perform wavefront sensing and compensation operations;
wherein said wavefront sensing and compensation operations are performed by said adaptive optical subsystem, and a phase-aligned image of the eye is captured by an image capture system, for use by a practitioner in examining, diagnosing and treating abnormalities in the eye; and
wherein a graphical representation of high order aberrations of the eye measured by said adaptive optical subsystem is displayed as two-dimensional contour maps that graphically depict contribution of pre-specified terms for aberrations of the eye.
2. The system of claim 1 , wherein said phase-aligned image of the eye is a digital image captured by said image capture system.
3. The system of claim 2 , wherein said graphical representation comprises coefficients corresponding to pre-specified terms that characterize aberrations of the eye.
