Patent number: 10175502Abstract: A contact lens for use in controlling the progression of myopia has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina.Type: GrantFiled: September 20, 2016Date of Patent: January 8, 2019Assignee: Vision CRC LimitedInventors: Brien Anthony Holden, Arthur Ho, Padmaja Rajagopal Sankaridurg, Thomas Arthur Aller, Earl Leo Smith

Publication number: 20170184876Abstract: 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.Type: ApplicationFiled: December 14, 2016Publication date: June 29, 2017Inventors: Arthur Ho, Padmaja Rajagopal Sankaridurg, Brien Anthony Holden, Percy Fabian Lazon, Xiang Chen, Fabian Conrad, Earl Leo Smith

Publication number: 20170038603Abstract: 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). In some embodiments the add power is substantially constant across the inner optic zone. In other embodiments the add power is variable across the inner optic zone. 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.Type: ApplicationFiled: October 18, 2016Publication date: February 9, 2017Inventors: Brien Anthony Holden, Gregor Schmid, Padmaja Rajagopal Sankaridurg, Arthur Ho, Aldo Abraham Martinez Mangos, Percy Fabian Lazon, Earl Leo Smith III

Publication number: 20170010478Abstract: A contact lens for use in controlling or retarding the progression of myopia in an eye has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone 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 of the lens is shaped to conform to the cornea of the eye and the front surface of the lens is shaped to provide—in conjunction with the rear surface—the desired optical properties of the central and peripheral optical zones.Type: ApplicationFiled: September 20, 2016Publication date: January 12, 2017Inventors: Brien Anthony Holden, Arthur Ho, Padmaja Rajagopal Sankaridurg, Thomas Arthur Aller, Earl Leo Smith

Publication number: 20160320634Abstract: A lens for an eye that includes a zone with a first power profile for images received by the retina on the fovea, a zone with a second power profile for images received by the peripheral retina on the nasal side and a zone with a third power profile for images received by the peripheral retina on the temporal side. The first power profile is selected to provide clear or acceptable vision and the second and third power profiles are selected to affect the peripheral image position.Type: ApplicationFiled: July 13, 2016Publication date: November 3, 2016Inventors: Arthur Ho, Padmaja Rajagopal Sankaridurg, Earl Leo Smith, III, Brien Anthony Holden

Publication number: 20150331255Abstract: An ophthalmic lens element includes an upper distance viewing zone and a lower near viewing zone. The upper distance viewing zone includes a central region with a first refractive power for clear distance vision and peripheral regions that are relatively positive in power compared to the first refractive power. The lower near viewing zone has a central region that is relatively positive in power compared to the first refractive power to account for accommodative lag. The powers of the peripheral regions of the lower near viewing zone are one of: i) equal to the power of the central region of the lower near viewing zone, ii) relatively positive in comparison to the power of the central region of the lower near viewing zone.Type: ApplicationFiled: March 14, 2013Publication date: November 19, 2015Inventors: Padmaja Rajagopal Sankaridurg, Cathleen Fedtke, Leslie Alan Donovan, Earl Leo Smith, III, Arthur Ho, Brien Anthony Holden
