  • Patent number: 10191303
    Abstract: Bimodulus multifocal ophthalmic lenses for correcting presbyopia include an inner optic portion characterized by a rigidity greater than a rigidity of an outer peripheral portion. When applied to an eye, the ophthalmic lenses are configured to provide one or more lenticular volumes between the posterior surface of the lens and the cornea. The ophthalmic lenses are further characterized by features on a surface of the lens for improving multifocal visual acuity. The disclosure further relates to methods of correcting presbyopia using the ophthalmic lenses.

  • Patent number: 9551884
    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.

  • Publication number: 20150092154
    Abstract: The present invention is directed to a non-deforming contact lens for keratoconus patients having a displaced central zone. In particular, the central zone is displaced from the geometric center of the lens. The shape of the central zone is egg or spoon-shaped and is rotationally asymmetrical with one semi-meridian that is shorter than a corresponding semi-meridian. An intermediate transition zone is formed integral with the periphery of the central zone, and a peripheral zone is formed integral with the periphery of the intermediate transition zone, forming a round contact lens.

  • Publication number: 20140132915
    Abstract: The different illustrative embodiments provide a method, computer program product, and apparatus for manufacturing a scleral contact lens. A number of dimensions for the scleral lens is generated based on a shape of an eye. An alteration to a first wavefront of light caused by the first wavefront of light traveling through a pupil of the eye is identified. A modification configured to be made to a posterior surface of the scleral lens is generated based on the alteration. The modification removes the alteration for a second wavefront of light traveling through the scleral lens and the pupil of the eye.

  • Patent number: 8678584
    Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.

  • Publication number: 20140043588
    Abstract: The disclosure relates to the use of contact lenses for treating ophthalmologic conditions, such as presbyopia, induced myopia, computer vision syndrome, insufficient accommodation, or a condition associated with insufficient accommodation. The contact lens may be selected based on a measured sagittal depth and/or eccentricity of the cornea. When fitted, fluid may accumulate between the cornea of the eye and the contact lens. The lens may exhibit a sufficient amount of apical clearance such that when the wearer blinks, the lens moves no more than 1 mm on the eye. The lens may be structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.

  • Publication number: 20130070200
    Abstract: A conformable covering comprises an outer portion with rigidity to resist movement on the cornea and an inner portion to contact the cornea and provide an environment for epithelial regeneration. The inner portion of the covering can be configured in many ways so as to conform at least partially to an ablated stromal surface so as to correct vision. The conformable inner portion may have at least some rigidity so as to smooth the epithelium such that the epithelium regenerates rapidly and is guided with the covering so as to form a smooth layer for vision. The inner portion may comprise an amount of rigidity within a range from about 1×10?4 Pa*m3 to about 5×10?4 Pa*m3 so as to deflect and conform at least partially to the ablated cornea and smooth an inner portion of the ablation with an amount of pressure when deflected.

  • Patent number: 8246167
    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.
