A head stabilizer device includes a strap to be secured laterally around the head of a patient lying in a supine position on an operating table and around the operating table to hold the patient's head in a stabilized, non-moving position during eye surgery. The strap carries a fixation surface to be disposed along the patient's forehead for fixating a superior rectus bridle suture with controlled tension to optimally position the eye for surgery while allowing the tension and fixation site for the superior rectus bridle suture to be adjusted during surgery to reposition the eye.

A surgical drape and head stabilizer device includes a surgical drape and a strap made or assembled as part of the surgical drape to be secured laterally around the head of a patient lying in a supine position on an operating table and around the operating table to hold the patient's head in a stabilized, non-moving position during eye surgery. The drape or strap carries a fixation surface to be disposed along the patient's forehead for fixating a superior rectus bridle suture with controlled tension to optimally position the eye for surgery while allowing the tension and fixation site for the superior rectus bridle suture to be adjusted during surgery to reposition the eye. A surgical drape and drainage device includes a surgical drape, a fluid collection bag on the surgical drape, a drain for communicating with the eye and the fluid collection bag to drain excess fluid from the eye into the fluid collection bag and a drain holder on the drape for releasably securing the drain.

A surgical knife blade includes a cutting blade for penetrating tissue of the eye. First indicia is carried on the cutting blade proximally spaced from a tip thereof for being aligned with an external surface of the tissue when the cutting blade is inserted tip first in the tissue to form an initial incision having a depth equal to the distance that the first indicia is spaced proximally from the tip. The cutting edge is configured to form a subsurface tunnel within the thickness of the tissue when the cutting blade is moved from the initial incision along a plane transverse to the plane of the initial incision. Second indicia is carried on the blade proximally spaced from the tip for being aligned relative to the initial incision to gauge the length of the subsurface tunnel. A method of making sutureless incisions in the eye includes the steps of inserting the knife blade in the tissue along a plane transverse to the tissue to form the initial incision, aligning the first indicia with the external surface to obtain a depth for the initial incision equal to the distance that the first indicia is spaced from the tip, moving the knife blade from the initial incision along a plane transverse to a plane of the initial incision to form the subsurface tunnel, aligning the second indicia relative to the initial incision to gauge the length of the tunnel and making a second incision from the tunnel through the tissue along a plane transverse to the plane of the tunnel.

An intraocular lens optic (e.g. FIG. ) having a maximum thickness of 500 microns () and a diameter of 6 millimeters, with concentric rings on the anterior surface of the lens. The lens, coupled with suitable haptic designs, is to be implanted within the lens capsule () of the eye after surgical removal of the natural crystalline lens. The anterior surface of the lens () has concentric rings () with steps of approximately 10 microns () that can be concave, convex or piano, with the edge of the step parallel in each case to the light rays traversing the lens at that point. The posterior surface of the lens () is aspherical and smooth. The concentric rings focus 95% or better of light at a specific target point on the retina, thus making a monofocal lens, with focal flexibility provided through haptic design providing movement of the lens forward in the posterior chamber in response to contraction and expansion of the ciliary body and concomitant repositioning of the zonules. The inventive lens is a unitarily formed, seamless body comprised preferably of hydrophilic acrylates or acrylates and silicone blends. Other possible materials include hydrophobic acrylates, polymethylmethacrylate (such as for example PMMA) or acrylic blends. The inventive lens, being less than 500 microns thick, provides greater transfer of light through the lens, thus more closely replicating the function of a natural, emmotropic lens, while the thinness, making the lens lightweight, allows the ciliary body to move the lens with less effort, thus facilitating comfort in the presbyopic eye.

The invention is directed to a lens that comprises an optic and two haptic rings, one positioned to rest against the posterior capsule distally outward from the optic zone, the other to rest on the anterior capsule some distance from the equator. The haptic rings of the lens are connected by segments of haptic material that may be arched or straight, and sections of open space to provide for ample circulation of the aqueous humor. The optic is positioned against the posterior capsule as close as possible to the nodal zone of the eye.

The inventive is directed to a haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of the human eye. The haptic secures the lens in an appropriate position within the natural capsule so as to provide optimal visual acuity through the aphakic lens. The haptic ends are designed to position the lens neutrally, anteriorly or posteriorly within the lens envelope. At the connection point of the ribbon portion to the solid end plate of the haptic, the haptic may be notched to facilitate compressing the lens into its injector for insertion into the eye through an incision in the cornea. Once compressed and passed through the cornea, the implanted lens will be secured by the haptics in the lens capsule once all possible natural lens material and epithelial cells have been removed.
