Abstract: Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localised remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localised remodelling.

Abstract: A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (an add power).

While in some embodiments the inner optic zone has a power designed to substantially eliminate lag of accommodation in the eye with myopia, in other embodiments, the add power may be higher.

Abstract: A spectacle eyeglass of progressive addition type has been designed for myopic children. To this purpose, an ergorama has been constructed, taking into account vision conditions encountered by the children in their everyday life. In particular, the eyeglass has a limited optical power increase between two reference eye directions (D1, D2), a start (D0) of the optical power increase which is located quite low in the eyeglass, and an offset value (OS) for a meridian line (ML) which is higher than that of eyeglasses designed for adults.

Abstract: Contact lenses incorporating asymmetric radial power profiles that increase the radial dioptric power from the center to the margin of the optical zone of the lenses may be utilized to prevent and/or slow myopia progression. The power profiles vary along different meridians.

Abstract: A contact lens or phakic IOC lens is provided with a peripheral portion that has a power profile that provides optical control of peripheral vision images. Typically, the central portion of the lens is also provided with optical control. The power profile of the lens at the boundary of the central and peripheral portions meets certain boundary conditions that ensure that the lens provides a desired or selected vision correction. Because the peripheral portion of the lens provides optical control that defocuses the peripheral vision image relative to the retina, the lens can be used to prevent or inhibit growth of the eye, thereby preventing or inhibiting myopia or the effects of myopia.

Abstract: Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than ?6D central refractive error. In one example, a kit or set of lenses (50, FIG. 15) can have multiple parts or sub-sets (52, 54) each comprising a compartmented container (56a, 56b) with lenses (58a, 58b) arranged according to increments of central corrective power (59a, 59b). The lenses (58a) of the first part (52) have four steps (60a, 61a, 62a, 64a) of peripheral power or defocus to provide therapeutic effect and, while the lenses (58b) of the second part (54) also have four steps (60b, 61b, 62b, 64b), the level of therapeutic effect is higher.

Abstract: A method is provided for addressing myopia progression or inclination to myopia in which the influence of accommodative lag stress on myopia is reduced or eliminated to counter eye axial length growth. User depth of focus is increased to relieve stress from overall accommodative effort and stress from accommodation and accommodative lag to retard myopia progression and enable continuous and long tem treatment by the user.

Abstract: Methods of making or providing ophthalmic lenses include using accommodative error measurements in the design or selection of one or more ophthalmic lenses. In some examples, the ophthalmic lenses are contact lenses.

Abstract: A lens is provided that is capable of preventing or slowing the progression of myopia when worn by a person. The lens has a power profile that reduces on-axis and off-axis hyperopic defocus created by the optics of the eye by creating on-axis and off-axis myopic defocus. The on-axis and off-axis myopic defocus is created by providing light rays that pass through a central vision region of the optical portion and light rays that pass through a peripheral region of the optical portion an increase in positive (plus) power. The overall effect is to prevent or slow the progression of myopia without any perceptible degradation in the person's central vision.

Abstract: A contact lens (10) for use in controlling or retarding the progression of myopia in an eye has a central optical zone (20) approximating the normal diameter of the pupil of the eye (22) that gives clear central vision at distance for the wearer. An annular peripheral optical zone 24 that is substantially outside the diameter of the pupil is formed around the central optical zone (20) with greater refractive power than that of the central zone (22) so that oblique rays entering the eye through the peripheral optical zone (24) will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface (16) of the lens is shaped to conform to the cornea of the eye and the front surface (18) of the lens (10) is shaped to provide—in conjunction with the rear surface (16)—the desired optical properties of the central and peripheral optical zones.

Abstract: The present invention provides a new method and system for preventing myopia acquisition in children and young adults. There is strong evidence that near work might lead to myopia. The axial length of a human eye is growing in the first 25 years of life. There is experimental evidence for feed-back loops to control this growth. Prolonged near-work might interfere with these feed-back loops in a way that the axial length growth accelerates to provide perfect near vision—myopia. Using reading glasses in normal-sighted children and young adults prevents interference of prolonged near-work with axial length growth, hence preventing environmentally driven myopia acquisition.

Abstract: A method or process for providing an anti-myopia lens or treatment for a patient's eye with progressive myopia, which involves (in one form) generating biometric data relating to the central and peripheral refractive errors of the eye, optionally together with data relating to the patient's visual or lifestyle needs and the patient's predisposition to progressive myopia. This data is input to a processor or algorithm that generates a basic lens design, a customised design or a program for reshaping the cornea of the eye. The selected modality is applied to the patient and its suitability is assessed with the result of the assessment feedback to the algorithm to generate a refined output design, which is applied to the patient. The process is repeated at intervals to check continued myopia progression and adjust the design of the selected modality after further measurement.

Abstract: In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure (e.g., corneal reshaping or by way of a contact lens) that focuses the peripheral image field in at least one meridian in front of the mid peripheral retina. In general, the therapeutic optical structure places the peripheral image field with reference to the retina in the direction and amplitude that growth is needed in order that the emerging myopia would be regulated. In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure that further produces a central retinal image that is focused on the central retina in at least one meridian so as to not reshape the central cornea.
