  • Publication number: 20240045236
    Abstract: A meniscus shaped lens module comprises one or more structures that decrease an amount of pressure or force to move one or more surfaces of the lens module and increase a separation distance of anterior and posterior surfaces of the module in order to provide an increase in optical power. A lens structure of the module comprises one or more of a pattern of a surface of a central chamber, a meniscus, a reduced diameter or a soft material in order to provide increased amounts of curvature of an outer contact lens surface with decreased amounts of pressure. The pattern can be formed in one or more of many ways, and may comprise one or more of folds, patterning, bellows or concertinaed surface of an optically transmissive material having a substantially uniform thickness such as a sheet of a membrane material.

  • Publication number: 20240004219
    Abstract: A lens for refractive tear shaping, including a curved lens body defining an anterior partial thickness cavity indented into its anterior surface. The anterior partial thickness cavity has an anterior facing tear shaping surface structured to form a tear lens within the anterior partial thickness cavity. The anterior partial thickness cavity is structured to define a tear lens within the anterior partial thickness cavity by interaction between a tear film of the eye and the anterior facing base tear shaping surface. The posterior curvature of the tear lens is dependent on the shape of the anterior facing base tear shaping surface.

  • Publication number: 20230414097
    Abstract: An OCT axial length measurement device is configured to measure an area of the retina within a range from about 0.05 mm to about 2.0 mm. The area can be measured with a scanned measurement beam or plurality of substantially fixed measurement beams. The OCT measurement device may comprise a plurality of reference optical path lengths, in which a first optical path length corresponds to a first position of a cornea, and a second optical path length corresponds to a second position of the retina, in which the axial length is determined based on a difference between the first position and the second position. An axial length map can be generated to determine alignment of the eye with the measurement device and improve accuracy and repeatability of the measurements. In some embodiments, the OCT measurement device comprises a swept source vertical cavity surface emitting laser (“VCSEL”).
