Epikeratoplasty A surgical procedure on the cornea aimed at correcting ametropia. The patient's corneal epithelium is removed and a donor's corneal disc (or lenticule) that was previously frozen and reshaped to produce a new anterior curvature is rehydrated and sutured to Bowman's membrane.

Method and apparatus to guide laser corneal surgery with optical measurement

InactiveUS20070282313A1Faster visual recoveryLess invasiveLaser surgerySurgical instrument detailsRefractive errorPhototherapeutic keratectomy
Optical coherence tomography (OCT) is used to map the surface elevation and thickness of the cornea. The OCT maps are used to plan laser procedures for the treatment of an irregular, opacified or weakened cornea, and in the treatment of refractive errors. In the excimer laser phototherapeutic keratectomy (PTK) procedure, the OCT data is used to plan a map of ablation depth needed to restore a smooth optical surface. In the excimer laser photorefractive keratectomy procedure, OCT mapping of epithelial thickness is used to achieve clean laser epithelial removal. In femtosecond laser anterior keratoplasty procedure, OCT data is used to plan the depth of femtosecond laser dissection to remove an anterior layer of the cornea, leaving a smooth recipient bed of uniform thickness to receive a disk of donated corneal tissue. The linkage of an OCT system to a precise laser surgical system enables the performance of new procedures that are safer, less invasive and produce faster visual recovery than conventional surgical procedures.

Tacrolimus ophthalmic preparation and preparation method thereof

ActiveCN107929235AMinimal eye irritationImprove complianceOrganic active ingredientsSenses disorderConjunctival xerosisPatient compliance
The invention provides a tacrolimus ophthalmic preparation and a preparation method thereof, and belongs to the technical field of pharmaceutical preparations. According to the present invention, thetacrolimus ophthalmic preparation has a micro-emulsion-like structure, is clarified and transparent, has good patient compliance, is prepared from tacrolimus, oil for injection, a surfactant, a stabilizer, an osmotic pressure regulator, a preservative, a pH value regulator, a tackifier and water for injection, and is used for preventing and treating immunological rejection after corneal transplantation or immunological corneal xerosis and conjunctival xerosis. According to the present invention, with the tacrolimus ophthalmic preparation, the problem of the water insolubilization of tacrolimusis solved, the tacrolimus is firstly prepared into the clarified and transparent eye drops with the micro-emulsion-like structure, the irritation on the eyes by the existing tacrolimus-suspended ophthalmic eye drops can be substantially reduced, and the patient compliance can be improved, such that the tacrolimus ophthalmic preparation of the present invention is suitable for the long-term use byimmunological rejection after corneal transplantation, corneal xerosis and conjunctival xerosis, and other patients with indications.

Device for providing and inserting a transplant or implant into a human or animal body and ready-to-use set comprising said device

PendingUS20210244530A1Simple and reliable provision and insertionSimple designEye implantsHuman bodyLamellar keratoplasty
The invention relates to a device for providing and inserting a transplant or implant into a human or animal body, more particularly for ophthalmological operations, preferably for performing a lamellar keratoplasty, such as a DMEK operation, comprising a cartridge (1) or sleeve, which has a holding region (2) for the transplant or implant and two opposite end openings (3, 4) each fluidically connected to the holding region (2), wherein the first opening (3) has a larger diameter than the second opening (4) and wherein, in order to produce a fluidic connection between the holding region (2) and a syringe (5), both openings (3, 4) can be coupled to the syringe (5) directly or by means of a connecting apparatus. With a view to simply and safely providing and inserting a transplant or implant into the body by simply designed means, the device is designed and further developed in such a way that the cartridge (1) or sleeve is mounted in a holder (6) and that the holder (6) has a pivoting apparatus (7) for pivoting the cartridge (1) or sleeve about a pivot axis (8) into a coupling position for coupling at least one of the two openings (3, 4) to the syringe (5). The invention further relates to a ready-to-use set comprising a device as described above in a sterile packaging.

Tearing instrument for corneal posterior lamella in ophthalmology

PendingCN108542591ATransplant avoidanceWill not cause decompensationLaser surgeryCorneal endotheliumEpikeratoplasty
The invention relates to a tearing instrument for the corneal posterior lamella in the ophthalmology. The tearing instrument for the corneal posterior lamella in the ophthalmology comprises tearing forceps and auxiliary hooks; the tearing forceps are provided with a forceps handle, forceps arms, inclined clamping arms and forceps teeth; the forceps handle is connected with the two forceps arms; the inclined clamping arms are connected with the two forceps arms respectively, and the forceps teeth are located at the tail ends of the inclined clamping arms; an include angle is formed between eachinclined clamping arm and the corresponding forceps arm. The direction of the forceps teeth faces the inner sides of the inclined clamping arms. The auxiliary hooks are provided with hook handles, hook arms and hook heads, and the hook arms are connected to the lower ends of the hook handles; the hook arms are downward bent in the reverse direction, and the bent direction of the hook arms is identical to that of the inclined clamping arms. The tearing instrument for the corneal posterior lamella in the ophthalmology has the advantages that through the tearing surgery of the anterior chamber corneal posterior lamella, the case of the turbid residual corneal posterior lamella after deep anterior lamella keratoplasty can be prevented from secondary keratoplasty; meanwhile, decompensation ofthe function of corneal endothelium cannot be caused. The instrument is convenient to operate, the cost can be lowered, and the complication risks are reduced.
