Abstract

Described herein are systems and/or methods for designing a system of contact lenses with interocular refractive disparity (i.e. anisometropia) for presbyopes. An example method may comprise a step of determining a plurality of lenses for inclusion in a system of contact lenses for treating presbyopes. Each of the plurality of lenses may be configured for an optical correction and may have a power profile associated therewith. The plurality of lenses may be grouped based on the optical correction. Each of the lenses in a particular group may have a different power profile. The example method may comprise a step of creating, based at least on the plurality of lenses and an add need, a fit guide. The fit guide may provide an interocular disparity of effective add. The interocular disparity of effective add may be determined by optimizing cyclopean performance across a range accommodative demands and light levels.

Claims (443)

1. A method for fitting a presbyopic patient with first and second contact lenses selected from a system of contact lenses, the method comprising the steps of:

determining a plurality of lens types for inclusion in a system of contact lenses for treating presbyopes, wherein the lens system comprises at least three lens types (lens A, a lens B, and a lens C designation),

wherein each of the plurality of lenses is configured for an optical correction and has a power profile associated therewith,

wherein the plurality of lenses are grouped based on the optical correction and wherein each of the lenses of a particular type has a different power profile;

determining a fit profile for said patient determined at least based on a refractive and a cylinder corrective need of said patient, an ADD power need of said patient, and an effective ADD of said paitent;

simulating, based on said fit profile, one or more visual performance manifolds, wherein each visual performance manifold is generated based at least on lens designs of said plurality of lens types, an eye model, and environmental conditions;

generating a customized fit guide for said patient for said plurality of lens types, wherein said customized fit guide is based at least on said fit profile of said patient, and interocular disparity of effective ADD of said patient; and

selecting said fits and second contact lenses for said patient based on said generated fit guide.

2. The method of claim 1 , wherein each lens group comprises at least three center-near continuous multifocal lenses.

3. The method of claim 1 , wherein each group of lenses comprises three lenses.

4. The method of claim 1 , wherein each group of lenses comprises four lenses.

5. The method of claim 1 , wherein each group of lenses comprises five lenses.

6. The method of claim 1 , wherein the optical correction is between −20 D and +20 D.

7. The method of claim 1 , wherein determining a plurality of lens groups comprises determining a visual performance manifold for one or more of the lenses in the plurality of lens groups.

8. The method of claim 1 , wherein the fit guide comprises one or more of:

9. A system of fitting a presbyopic patient with contact lenses with interocular disparity for presbyopes, the system comprising:

a plurality of lens types for treating presbyopes, wherein the lens system comprises at least three lens types (lens A, a lens B, and a lens C designation),

wherein each of the plurality of lenses is configured for an optical correction and has a power profile associated therewith,

wherein the plurality of lenses is grouped based on the optical correction and wherein each of the lenses of a particular type has a different power profile,

a fit guide indicating which of the plurality of lenses is to be worn on a dominant eye and a non-dominant eye, wherein the fit guide created by:

determing, based on at least a refractive and a cylinder corrective need of said patient, a fit profile for said patient, an ADD power need of said patient, and an effective ADD of said patient; and

simulating, based on at least said fit profile, one or more visual performance manifolds, wherein each visual performance manifold is simulated based at least on lens designs of said plurality of lens types, an eye model, and environmental conditions, wherein the fit guide comprises a customized fit guide generated for said presbyopic patient for said plurality of lens types, wherein said customized fit is based at least on said fit profile of said patient, and interocular disparity of effective ADD of said patient; and wherein the system is further configured to select first and second contact lenses for said presbyopic patient based on said generated customized fit guide.

10. The system of claim 9 , wherein each lens group comprises at least three center near continuous multifocal lenses.

11. The system of claim 9 , wherein each group of lenses comprises three lenses.

12. The system of claim 9 , wherein each group of lenses comprises four lenses.

13. The system of claim 9 , wherein each group of lenses comprises five lenses.

14. The system of claim 9 , wherein the power profile is between −20 D and +20 D.

15. The system of claim 9 , wherein the fit guide is dependent on a visual performance manifold for one or more of the lenses in the plurality of lens groups.

16. The method of claim 9 , wherein the fit guide comprises one or more of:
