Disclosed herein is a contact lens comprising a rounded, minus-carrier, lenticular-like curve over a central, upper portion of the lens that allows the contact lens to translate upwards in downgaze.

An ocular lens may include a lens body including a first surface. The first surface may include a first zone including a plurality of friction reduction structures arranged in alignment with the movement of a user's upper eyelid during blinking. The first surface may also include a second zone including a plurality of friction reduction structures arranged in alignment with the movement of a user's lower eyelid during blinking.

Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface. The second surface may be configured to abut at least a portion of an eye of a wearer. The example ophthalmic lens may comprise a lens stabilization zone disposed adjacent the first surface. At least a contour of the lens stabilization zone may be configured to minimize a recovery time for the ophthalmic lens to orient to a resting position from a misaligned position.

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.

Operation of an electronic contact lens takes into account saccadic motion of the eye and reduced visual perception during saccades (saccadic suppression). The user's eye motion is tracked, and onset of a saccade is detected based on the eye's motion. For example, saccades may be detected when the eye's acceleration or jerk exceeds a threshold. The endpoint of the saccade is then predicted in real-time while the saccade is still occurring. This may be the temporal endpoint (i.e., when the saccade ends) and/or the positional endpoint (i.e., the eye position at the end of the saccade). Operation of the electronic contact lens is adjusted based on the predicted endpoint.

The stabilized contact lens methods and apparatus disclosed herein provide improved stabilization of a contact lens placed on a cornea of an eye. The contact lens comprises stabilization zones that allow the lens to repeatedly and consistently orient on the cornea such that a sensing zone located on the lower portion of the lens is located inferiorly to engage the lower eyelid. The stabilized contact lens can provide a lower pressure sensing zone with decreased thickness for pressure or other sensing related to the lower eyelid. The decreased thickness has the advantage of improving coupling between forces from an eyelid and a lower chamber of a fluidic module. The improved coupling allows increased amounts of fluid to move between the lower chamber and an upper optical chamber coupled to the lower chamber, such that the upper chamber can increase curvature and optical power in response to pressures of the eyelid.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or optical tissues is performed to address various types of vision correction.

Provided is an orthokerato lens including a central portion located on a center of a lens and configured to change a refractive index by pressurizing a cornea, a fitting portion configured to form a negative pressure between the lens and the cornea to pile epithelial cells moved from the central portion, a fixing portion configured to be in contact with an eyeball and align the lens such that the center of the lens is located at a center of the cornea, a peripheral portion configured to allow tears between the lens and the eyeball to circulate, and a circulation hole configured to penetrate the central portion.

A contact lens for shaping a cornea of an eye of a patient to treat high cylinder astigmatism may include a peripheral portion, an alignment portion, a treatment portion, a reverse portion, and a staining feature. The peripheral portion may cause migration of epithelial cells from a periphery of a cornea of the eye of the patient towards a center of the cornea of the eye of the patient. The alignment portion may align the contact lens on the cornea. The treatment portion may cause migration of the epithelial cells from the center of the cornea towards the periphery of the cornea. The reverse portion may relieve pressure caused by the migration of the epithelial cells. The staining feature may contact the cornea, thereby reshaping the cornea to treat high cylinder astigmatism. The staining feature may apply a ribbon-shaped staining pattern to the cornea across the contact lens.
