First Claim
Patent Images
1. A method for vision correction of an eye having a corneal epithelium and a Bowman'"'"'s membrane disposed under the corneal epithelium, the method comprising:
- separating the corneal epithelium from the Bowman'"'"'s membrane to form an epithelial cell layer separated from the Bowman'"'"'s membrane and a pocket extending between the epithelial cell layer and the Bowman'"'"'s membrane, the epithelial cell layer separated from the Bowman'"'"'s membrane having a periphery substantially attached to the Bowman'"'"'s membrane to fix a lens to the eye; and
inserting the lens into the pocket between the epithelial cell layer and the Bowman'"'"'s membrane of the eye, such that the lens is substantially fixed on the Bowman'"'"'s membrane of the eye with the epithelial cell layer.

Abstract
Methods of correcting vision are described. The methods include inserting a lens into a corneal epithelial pocket or a pocket created between a corneal epithelium of an eye of a patient and Bowman'"'"'s membrane of the eye. A lens is inserted into the pocket to correct vision. Certain methods include one or more steps of cooling the corneal epithelium, and applying an aqueous liquid to the eye. The lenses that are inserted into the pocket can include collagen, including recombinant collagen, synthetic polymeric materials, and combinations thereof.

72. A method for vision correction of an eye having a corneal epithelium and a Bowman'"'"'s membrane disposed under the corneal epithelium, the method comprising:
-
cooling the corneal epithelium of eye; separating the corneal epithelium from the Bowman'"'"'s membrane to form an epithelial cell layer separated from the Bowman'"'"'s membrane and a pocket extending between the epithelial cell layer and the Bowman'"'"'s membrane, the epithelial cell layer separated from the Bowman'"'"'s membrane having a periphery substantially attached to the Bowman'"'"'s membrane to fix a lens to the eye with the corneal epithelial layer; and inserting a lens into the pocket between the epithelial cell layer and the Bowman'"'"'s membrane of the eye, such that the lens is substantially fixed on the Bowman'"'"'s membrane with the epithelial cell layer. - View Dependent Claims (73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87)

88. A method for vision correction of an eye having a corneal epithelium and a Bowman'"'"'s membrane disposed under the corneal epithelium, the method comprising:
-
separating the corneal epithelium from the Bowman'"'"'s membrane to form an epithelial cell layer separated from the Bowman'"'"'s membrane and a pocket extending between the epithelial cell layer and the Bowman'"'"'s membrane, the epithelial cell layer separated from the Bowman'"'"'s membrane having a periphery substantially attached to the Bowman'"'"'s membrane to fix a lens on the Bowman'"'"'s membrane with the corneal epithelial layer; inserting the lens into the pocket between the epithelial cell layer and the Bowman'"'"'s membrane of the eye, such that the lens is substantially fixed to the eye with the epithelial cell layer; and applying an effective amount of an epithelium preserving agent to the epithelium, wherein the epithelium preserving agent includes at least one cellulosic component. - View Dependent Claims (89)

90. A method for vision correction of an eye having a corneal epithelium and a Bowman'"'"'s membrane disposed under the corneal epithelium, the method, comprising:
-
applying a liquid to the corneal epithelium of the eye, the liquid being effective in loosening the epithelium substantially without killing epithelial cells; treating the epithelium to provide or maintain the epithelium in a moisturized state, wherein the treating step comprises applying a gel containing composition to the epithelium; raising a portion of the loosened, moisturized epithelium to separate the portion of the corneal epithelium from the Bowman'"'"'s membrane to form an epithelial cell layer separated from the Bowman'"'"'s membrane and a pocket, the pocket extending between the epithelial cell layer and the Bowman'"'"'s membrane, the epithelial cell layer separated from the Bowman'"'"'s membrane having a periphery substantially attached to the Bowman'"'"'s membrane to fix a lens to the eye; forming one or more incisions in the raised portion of the epithelium to access the pocket between the corneal epithelium and Bowman'"'"'s membrane; and inserting a lens into the pocket through the one or more incisions such that the lens is substantially fixed on the Bowman'"'"'s membrane of the eye with the epithelial cell layer. - View Dependent Claims (91, 92, 93)
