Abstract: The present invention discloses an implant for altering the iris color, consisting of a completely or partially transparent, semi-transparent or non-transparent, colored, biocompatible and flexible material, wherein the implant is formed annularly, and forms an annular area coming to rest on the iris of an eye, and comprises a central circular opening, wherein at least one attaching means is formed for detachable attachment of the implant the iris. The attaching means is disposed within the annular area of the implant. The invention further discloses methods of locating and fixing an implant for altering the iris color.

Abstract: The present invention discloses a blade for a surgical device, namely a device for processing the cornea of a human or animal eye, comprising a blade body, a front and a rear edge, and two lateral edges connecting the front and rear edges of the blade, the front edge serving for processing the cornea, wherein an end of the front edge of the blade is formed bluntly, such that it is not suitable for severing the cornea. The present invention further relates to a surgical device, namely a device for processing the cornea of a human or animal eye.

Abstract: A suction ring providing an inferior engaging surface and a superior engaging surface that engages and grips the ocular globe, immobilizing the ocular globe relative to a corneal surgical procedure. The inferior engaging surface grips the sclera of the ocular globe while the superior engaging surface grips the corneal region. The suction ring also provides an aperture sized to receive and expose the cornea for a surgical procedure. The suction ring has a non-circular gripping structure to provide a closer fit to abnormally shaped ocular globes and corneas. The aperture is non-circular to enable the surgeon to obtain a non-circular corneal disk during a lamellar keratotomy procedure.

Abstract: An improved microkeratome includes a guide ring assembly for placement on the ocular globe and means for temporarily fixing the guide ring to the ocular globe. A cutting head contains an improved cutting blade having an arcuate cutting edge suitable for corneal resections. A vertical support assembly is connected to the guide ring and supports the cutting head for rotation about a horizontal axis such that rotation of the cutting head about the horizontal axis moves the cutting blade along an arcuate cutting path into engagement with the cornea of the ocular globe, whereby the arcuate cutting edge of the cutting blade cuts a substantially rounded corneal disk. An improved method related to the use of the arcuate cutting blade is also provided.

Abstract: An adjustable suction ring for immobilizing the eyeball for use with any corneal surgical procedure that involves immobilizing the eyeball in relation to surgical tools. The suction ring is adjustable to fit eyeballs of differing diameters. The suction ring consists of an upper portion and a lower portion joined by a threaded connection. By rotating the lower section and backing out the threads, the distance between the upper engaging surface and the lower engaging surface is widened, thereby decreasing the curvature radius of the inferior engaging surface resulting in a proper fit between the suction ring and a small diameter eyeball. By rotating the lower section oppositely, the distance between the upper engaging surface and the lower engaging surface is shortened, thereby effectively increasing the curvature radius of the inferior engaging surface resulting in a proper fit between the adjustable suction ring and a large diameter eyeball.

Abstract: A method and system control the depth of corneal ablation during optical surgery by mapping the anterior and posterior surfaces of a patient's cornea to obtain full pachymetric topographical mapping of the patient's cornea. The patient's corneal pachymetric topographical mapping is used to identify a desirable corneal bed, and to guide a surgical laser in ablating a portion of the anterior surface of the patient's cornea to produce the desired corneal bed for appropriate vision correction.

Abstract: An apparatus which attaches to microkeratome surgical devices. The disposable microkeratome blade housing apparatus securely attaches to the surgical devices but remains independent of the motor, gearing and cutting head components. In a first embodiment, the blade housing includes a knife edged blade, a blade holder, plaque and flexible coupling structure. The snap tight coupling structure provides a self-positioning, secure attachment of the housing to existing compatible and accommodating microkeratomes. In a second embodiment, the blade housing and cutting head are integral and include a knife edged blade, a blade holder, and a plaque. The blade housing/cutting head combination of the second embodiment is entirely disposable and fixedly secured to said motor. In both embodiments, the blade holder is acted upon by the motor and gearing to oscillate the blade holder in the housing.

Abstract: A microkeratome and related surgical methods for performing lamellar keratotomies are provided. The microkeratome includes a guide ring assembly for placement on the eyeball, or ocular globe such that the globe's cornea protrudes therethrough. The guide ring can be temporarily fixed to the ocular globe, immobilizing the eyeball relative to the instrument. A cutting blade suitable for corneal resections is carried in a cutting head over the guide ring through a cutting path defined by the guide ring. An adjustable float head, also generally known as a plaque, is connected to the cutting head for at least partially compressing the cornea ahead of the blade, so as to set the desired thickness of the corneal resection. The cutting head and float head can be driven across the guide ring, whereby the blade cuts at least partially through the cornea to perform the lamellar keratotomy.
