SCLERAL BUCKLE FOR ALLEVIATION OF RETINAL DETACHMENT AND REFRACTIVE ERROR
20220241109 · 2022-08-04 ·

A rhegmatogenous retinal detachment (RRD) occurs when a tear in the retina leads to fluid accumulation with a separation of the neurosensory retina from the underlying retinal pigment epithelial (RPE); this is the most common type of retinal detachment and can lead to blindness. The present invention features an eye shape modification (ESM) system (a scleral buckle) for the prevention and repair of retinal detachment as well for the adjustment of refractive error and the prevention of induced refractive error caused by scleral buckles. The present invention creates a scleral buckle with protuberances on the interior surface of the buckle. These protuberances produce corrugation/indentations in the eye which allows for both axial and circumferential relaxation. Additionally, the present invention creates on scleral buckle that remove excess bulky material from the scleral buckle band, producing a scleral buckle that is easier and safer to surgically implant onto the eye.

Method for the amelioration of ectatic and irregular corneal disorders
11406531 · 2022-08-09 ·

Methods for the amelioration of ectatic corneal disorders using corneal augmentations are disclosed. The shape of the augmentation is determined using data obtained from mapping of a patient's cornea based on computerized corneal topography and tomography. Factors considered include the maximum keratometry and specific iso-deviation contours. In one embodiment, an augmentation is inlayed into a femtosecond created, intrastromal pocket. In a further embodiment, an onlay augmentation is positioned over a region of the cornea from which the epithelial layer has been removed. The onlay is held in place by glue, sutures, tucking under a perimeter chamfer, or some combination thereof, until the epithelial layer regrows over the augmentation. In a further embodiment, the inlay or only augmentation is followed by a post-augmentation, further reshaping of the corneal augmentation. In one embodiment, this further reshaping is photorefractive keratectomy (PRK) surgery. In another and a phototherapeutic keratectomy (PTK) surgery.

Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods

A system includes a scleral prosthesis and an insert. The scleral prosthesis includes a first end configured to be pulled through a scleral tunnel in an eye and a second end. Each end is wider than a middle portion of the scleral prosthesis. Two portions form the first end of the scleral prosthesis, and the portions are separated along at least half of a length of the scleral prosthesis. The scleral prosthesis is formed from a single integrated piece of material. The second end is undivided. The insert is configured to be placeable between the two portions. The two portions may be separated from one another without external interference, and the two portions may be configured to be pushed towards each other in order to reduce a width of the first end and then separate after release.

SHAPED CORNEAL SEGMENTS: CORNEAL ALLOGENIC INTRA-STROMAL DEVICES (RING SEGMENTS AND RINGS, MODIFIED DISCS, MODIFICATIONS) FOR INDUCING SHAPE CHANGE, REGULARIZATION AND STABILIZATION OF CORNEA IN CORNEAL ECTASIA AND OTHER CORNEAL CONDITIOINS AND FOR CORRECTION OF REFRACTIVE ERRORS
20220079743 · 2022-03-17 ·

A device for implantation into the cornea intra-stromally comprising allogenic comeal or scleral material or other bioengineered material including, but not limited to, processed collagen tissues, comprises a segment that is inserted into a comeal channel whereby the segment regularizes the conical cornea, gives an improved surface, improves biomechanical strength distribution and stability improves optical functionality, and improves/corrects the refractive error or gives other desired shape change effects.

METHODS AND MATERIALS FOR MODIFYING CORNEAL SHAPE
20220110738 · 2022-04-14 ·

Modifying corneal shape involves implantation of a segment of tissue in the corneal stroma, where the properties of the tissue segment and its anatomical placement provide a change in corneal topography. In particular, such methods and materials can be used for correction of defects in corneal shape, such as corneal ectasias.

Ophthalmic device for drug delivery

An ophthalmic implant for drug delivery. The implant includes a primary intracapsular device coupled to a secondary device, wherein, when implanted in a patient's eye, the primary intracapsular device is held in place by the patient's capsular bag and the secondary device is held in place by the primary intracapsular device. The implant may be inserted in the eye by injecting the primary intracapsular device into the eye either before or after attaching the secondary device to the primary intracapsular device, and subsequently positioning the joined secondary device and primary intracapsular device with the primary intracapsular device held in place by the patient's capsular bag and the secondary device held in place by the primary intracapsular device. The secondary device may be designed to hold a tertiary device that can be implanted and attached at the time of surgery or anytime postoperatively.

Cornea transplantation
11154191 · 2021-10-26 · ·

A planning device generating control data for a treatment apparatus for cornea transplantation using a laser device to separate a corneal volume by at least one cut surface in the cornea and to separate a transplant, from a surrounding transplantation material by at least one cut surface, wherein the planning device includes an interface supplying measurement data relating to parameters of the cornea. A computer defines a corneal cut surface which confines the corneal volume to be removed, and determines a transplant cut surface by using the transplantation material data and depending on the defined corneal cut surface. The transplant cut surface confines the transplant, and the computer generates one control data for each cut surface to control the laser, wherein the respective cut surfaces can be produced by the laser to isolate the corneal volume and the transplant and to make them removable.
