Abstract
Apparatus and methods are provided for reducing or eliminating the progression of myopia, including a lens having an intentionally created aberration pattern for reducing or eliminating the progression of myopia. The aberration pattern may comprise a positive spherical aberration that produces a wavefront error in which the paracentral wavefront is disposed in front of the retina, thereby producing a signal that counters axial length growth of the eye and preventing the progression of myopia.

Apparatus for reducing or eliminating the progression of myopia in a myopic eye, comprising:
- a lens having an aberration pattern for reducing the progression of myopia in the eye, wherein the aberration pattern comprises a positive spherical aberration,
- wherein the positive spherical aberration causes a wavefront error in which the paracentral wavefront is disposed in front of the retina of the eye, and the wavefront error produces a signal that counters axial length growth in the eye, thereby reducing the progression of myopia.
Apparatus for reducing or eliminating the progression of myopia in a myopic eye, comprising:
- a lens having an aberration pattern for reducing the progression of myopia in the eye, wherein the aberration pattern comprises a positive spherical aberration,
- wherein the lens is a hybrid contact lens having a substantially rigid central portion and a substantially flexible peripheral portion,
- wherein the hybrid contact lens includes substantially rigid optics and permits the centering of an aberration structure over the pupil of the eye, and the rigid optics maintain a substantially constant aberration structure during use of the contact lens.
A method of creating a lens for a lens-eye system including a myopic eye, the method comprising the steps of:
- measuring the residual aberrations in the eye using a diagnostic lens;
- and inducing an aberration pattern in the lens-eye system, thereby reducing the progression of myopia in the eye,
- wherein the lens is a hybrid contact lens having a substantially rigid central portion and a substantially flexible peripheral portion,
- wherein the hybrid contact lens includes substantially rigid optics and permits the centering of an aberration structure over the pupil of the eye, and the rigid optics maintain a substantially constant aberration structure during use of the contact lens.
