Patent number: 8192018Abstract: “Universal improvement” of vision is achieved by effectively changing the shape of the anterior refracting surface of the cornea to an ideal “turtleback” shape, on which is imposed the necessary curvature adjustment to achieve correction of distance vision. In accordance with one embodiment, the cornea is actually formed to the turtleback shape through corneal surgery, preferably laser ablation surgery. In accordance with a second embodiment, a contact lens with the desired distance corrected ideal turtleback shape on its anterior surface is positioned over the cornea.Type: GrantFiled: December 3, 2010Date of Patent: June 5, 2012Assignee: Scientific Optics, Inc.Inventors: Jonathan Grierson, David Lieberman

Publication number: 20110112805Abstract: Methods and apparatus are disclosed for causing the optical center of the eye to align “HIGH point” of the anterior surface of the cornea. In accordance with one aspect of the invention relating to corneal ablation procedures, the HIGH point of the eye is used as the pole of a spherical surface which is fitted approximately to a portion of the anterior surface of the cornea within a “bounded region.” For corneal ablation procedures, the “bounded region” comprises a generally inverted-cup shaped region of the anterior surface of the eye bounded at its periphery by a plane which is substantially perpendicular to a local z-axis. During the operation local high points which project above the spherical surface are ablated. According to another aspect of the invention relating to radial keratotomy procedures, a pair of incisions in the plane of a “great circle” are formed in the cornea to weaken and flatten it.Type: ApplicationFiled: January 11, 2011Publication date: May 12, 2011Applicant: Scientific Optics, Inc.Inventors: David Lieberman, Jonathan Grierson

Publication number: 20110037942Abstract: The carrier region extending beyond the optical portion of a contact lens overlying the cornea of an eye can be modeled in one universal shape that will fit all eyes. That shape is characterized by a curve of radius of curvature versus distance from the High point which is substantially linear with a first slope below a 10 mm diameter of the eye as projected onto a plane perpendicular to the optical axis, is substantially linear above 10 mm with a second slope which is substantially greater than the first slope, and which has an inflection point in the vicinity of approximately 10 mm. Preferably the first linear portion has a radius of curvature of approximately 7.6 mm at a diameter of about 7 mm, with a slope of about 0.13 (the first slope) and a radius of curvature of about 9 mm at a diameter of 12 mm, with a slope of about 0.45 (the second slope).Type: ApplicationFiled: March 31, 2009Publication date: February 17, 2011Applicant: Scientific Optics, Inc.Inventors: David M.

Patent number: 7338160Abstract: Eye measurements taken on a patient being fitted for contact lens will include a refraction test and an additional measurement representing corneal depth variation on the surface of an imaginary cylinder having the same diameter as the lens. This information then used during lens manufacture to produce lens in which the perimeter is not circular and does not lie in a plane, but which drops backwards towards the eye at appropriate points to produce a saddle-shaped perimeter.Type: GrantFiled: May 27, 2004Date of Patent: March 4, 2008Assignee: Scientific Optics, Inc. c/o Avalon VenturesInventors: David M.

Publication number: 20060189966Abstract: Methods and apparatus (610) are disclosed for diagnosing vision and improving vision in a manner which does not interfere with the natural shape of the cornea or its orientation relative to the remainder of the eye, but which changes its surface curvature appropriately to achieve the required correction of vision. The focus of the cornea (14) is adjusted so that different regions focus substantially to the same axis and preferably to substantially the same point on the axis. This can be accomplished by shaping the cornea (e.g. through ablation) or by applying an appropriate contact lens or other optical lens. In either case, correcting the central portions of the cornea should have a more significant effect on correcting focus scatter than correcting the more outward portions.Type: ApplicationFiled: June 3, 2003Publication date: August 24, 2006Applicant: Scientific Optics, inc.Inventors: David Lieberman, Jonathan Grierson

Patent number: 6669342Abstract: Methods, and apparatus are disclosed for performing corneal ablation procedures of the eye (12) in a manner which does not interfere with the natural shape of the cornea or its orientation relative to the remainder of the eye, but which changes its surface curvature appropriately to achieve the required correction of vision. Three preferred embodiments are described, which model the cornea to different degrees of accuracy. Once the model of the cornea is obtained (610, 620, 630), surface curvature is modified (650) to achieve the degree of correction in refraction that is necessary, as determined by an eye test of the patient. The modified model of the cornea is then utilized to control the removal of material from the surface of the cornea in a corneal ablation operation.Type: GrantFiled: May 22, 2002Date of Patent: December 30, 2003Assignee: Scientific Optics, Inc.Inventors: David M.
