CONTACT LENS SETS AND METHODS TO PREVENT OR SLOW PROGRESSION OF MYOPIA OR HYPEROPIA

摘要

METHODS FOR SLOWING PROGRESSION OF MYOPIA OR HYPEROPIA OF HUMAN PATIENTS INCLUDE A STEP OF PROVIDING CONTACT LENSES. THE CONTACT LENSES HAVE TWO OR MORE REFRACTIVE POWERS. A FIRST REFRACTIVE POWER PROVIDES CLEAR VISUAL ACUITY AND A SECOND REFRACTIVE POWER PROVIDES A DEFOCUSED RETINAL IMAGE TO THE HUMAN PATIENT. THE METHODS INVOLVE PROVIDING FIRST AND SECOND SETS OF THE CONTACT LENSES (10D & 10E), THE CONTACT LENSES OF THE SECOND SET (10E) HAVE A DIFFERENT OPTICAL DESIGN THAN THE CONTACT LENSES OF THE FIRST SET (10D). WITH THE PRESENT METHODS, AN EYE CARE PRACTITIONER IS ABLE TO SELECT ONE OR MORE CONTACT LENSES (10E) FROM THE SECOND SET OF CONTACT LENSES BASED ON ONE OR MORE OCULAR PARAMETERS OF THE PATIENT, ONE OR MORE RESPONSES OF THE PATIENT TO THE CONTACT LENS OF THE FIRST SET (10D), OR BOTH, TO PROVIDE AN IMPROVED CLINICAL BENEFIT TO THE PATIENT COMPARED TO THE BENEFIT PROVIDED BY THE FIRST SET OF CONTACT LENSES.
