Abstract

Claims (37)

1 . A surgical contact lens system for ophthalmic treatment with a laser beam, comprising:

a patient contact lens designed to reduce refractive errors of an eye including a spherical error of the eye and an astigmatism of the eye, the patient contact lens having a concave surface and a convex surface, the concave surface configured to be disposed outwardly from a cornea of an eye; and

a surgical contact lens having an eye end configured to be disposed outwardly from the convex surface of the patient contact lens and comprising:

a frame; and

an optical component coupled to the frame,

the patient contact lens configured to reduce pressure from the surgical contact lens to reduce corneal folding of a posterior surface of the cornea, the optical component of the surgical contact lens and the patient contact lens configured to transmit the laser beam to treat the eye.

2 . The surgical contact lens system of claim 1 , the patient contact lens configured to reduce the corneal folding of the posterior surface of the cornea such that wavefront error of the laser beam is reduced.

3 . The surgical contact lens system of claim 1 , the patient contact lens designed to reduce the refractive errors of the eye such that wavefront error of the laser beam is reduced.

4 . The surgical contact lens system of claim 1 , the patient contact lens comprising a material selected from hydrogel, silicone, silicone hydrogel, or polymethyl methacrylate (PMMA).

5 . The surgical contact lens system of claim 1 , the patient contact lens comprising a lens selected from a hydrogel contact lens, a silicone hydrogel contact lens, a gas permeable (GP) lens, a rigid gas permeable (RGP) lens, a scleral contact lens, a hybrid contact lens, or a polymethyl methacrylate (PMMA) lens.

6 . The surgical contact lens system of claim 1 , the eye end of the surgical contact lens configured to be disposed outwardly from a contact gel disposed between the convex surface of the patient contact lens and the eye end of the surgical contact lens.

7 . The surgical contact lens system of claim 1 , the surgical contact lens comprising a lens selected from an ocular Karickhoff four mirror lens, an ocular Karickhoff off-axis lens, an ocular Peyman lens, or a Singh mid-vitreous lens.

8 . The surgical contact lens system of claim 1 , the optical component of the surgical contact lens and the patient contact lens configured to transmit the laser beam to irradiate a floater in a vitreous of the eye.

9 . The surgical contact lens system of claim 1 , the surgical contact lens being hand-held.

10 . A method for using a surgical contact lens system for ophthalmic treatment with a laser beam, comprising:

disposing a patient contact lens outwardly from a cornea of an eye, the patient contact lens designed to reduce refractive errors of the eye including a spherical error of the eye and an astigmatism of the eye, the patient contact lens having a concave surface and a convex surface, the concave surface configured to be disposed outwardly from the eye;

disposing a surgical contact lens outwardly from the patient contact lens, the surgical contact lens comprising an optical component coupled to a frame, the surgical contact lens having an eye end configured to be disposed outwardly from the convex surface of the patient contact lens, the patient contact lens configured to reduce force from the surgical contact lens in order to reduce corneal folding of a posterior surface of the cornea; and

directing the laser beam through the optical component of the surgical contact lens and the patient contact lens to treat the eye.

11 . The method of claim 10 , further comprising:

reducing, by the patient contact lens, the corneal folding of the posterior surface of the cornea such that wavefront error of the laser beam is reduced.

12 . The method of claim 10 , further comprising:

reducing, by the patient contact lens, the refractive errors of the eye such that wavefront error of the laser beam is reduced.

13 . The method of claim 10 , further comprising:

disposing a contact gel outwardly from the convex surface of the patient contact lens to dispose the contact gel between the patient contact lens and the eye end of the surgical contact lens.

14 . The method of claim 10 , further comprising:

irradiating a floater in a vitreous of the eye by transmitting the laser beam through the optical component of the surgical contact lens and the patient contact lens.

15 . The method of claim 10 , the disposing the surgical contact lens outwardly from the patient contact lens further comprising:

placing the surgical contact lens outwardly from the patient contact lens by hand.

16 . A patient contact lens for ophthalmic treatment with a laser beam, comprising: the patient contact lens having:

a concave surface configured to be disposed outwardly from a cornea of an eye;

a convex surface configured to be in contact with an eye end of a surgical contact lens, the surgical contact lens comprising an optical component coupled to a frame, the optical component configured to transmit the laser beam to treat the eye,

the patient contact lens configured to:

reduce refractive errors of the eye including a spherical error of the eye and an astigmatism of the eye;

reduce pressure from the surgical contact lens to reduce corneal folding of a posterior surface of the cornea; and

transmit the laser beam to treat the eye.

17 . The patient contact lens of claim 16 , the patient contact lens configured to reduce the corneal folding of the posterior surface of the cornea such that wavefront error of the laser beam is reduced.

18 . The patient contact lens of claim 16 , the patient contact lens designed to reduce the refractive errors of the eye such that wavefront error of the laser beam is reduced.
