Patch endothelial keratoplasty for corneal perforations secondary to ocular surface disease: case series.

Background: Corneal perforation is an ophthalmic emergency. The conventional management of corneal perforation can be associated with severe complications especially in patients with ocular surface disease. Endothelial keratoplasty has been suggested as an alternative surgical technique for the management of corneal perforations.

Evaluating patients' satisfaction level after using 3D printed PEEK facial implants in repairing maxillofacial deformities.

Background: it is generally the case in any traumatic accident where a loss in hard tissue occurs to preform restorative plastic surgery, as there are many materials and approaches used to restore the loss, this research sheds the light on the use of one such material and approach being 3D printed facial implants manufactured from PolyEther Ether Ketone (PEEK) and to evaluate the level of patients' satisfaction following the use of said method in repairing maxillofacial deformities.

Materials And Methods: a research sample consisting of 10 patients with facial deformities underwent maxillofacial reconstructive surgery between 2020 and 2021 in the Department of Oral and Maxillofacial Surgery in the Tishreen University Hospital - Latakia - Syria. All patients underwent Computed Tomography (CT) scans, then the design of the required facial implant was carried out, the final form of the facial implant was printed from PolyEther Ether Ketone (PEEK), and then surgical work was performed, a check-up after 3 months of the surgical procedure was carried out to evaluate the level of satisfaction on a scale of 1-5.

Supply and Demand of Domestic Corneal Tissue and Its Implications on Export Potential-Using Australia as an Example.

Purpose: Corneal tissue importation is only possible if another country is able to export corneas without impacting its own domestic demand. Currently, there is little evidence to indicate whether export nations have such surplus capacity and in a position to export. To explore this concept, we examined our nation, Australia, which is reported to routinely decline donations because of its ability to meet domestic corneal transplant demand.

Factors Affecting Corneal Organ Culture Contamination: A 6-year Study at the New South Wales Tissue Bank.

Purpose: To report the rate of microbial contamination and analyze possible risk factors for contamination of banked corneas stored using the organ culture method.

Methods: Data from the New South Wales Tissue Banks incorporating the Lions NSW Eye Bank, between September 1, 2011, and November 30, 2017, were reviewed retrospectively. All corneas collected during this period and stored in organ culture storage media were tested for microbial contamination.

The use of donor scleral patch in ophthalmic surgery.

Scleral tissue has been in use in ophthalmology for many years although indications for use have varied. We retrospectively reviewed scleral transplant tissue requests over a 12 month period at a local eye bank and confirmed a small but significant demand for the use of scleral tissue. Iatrogenic surgical complications are the primary indication for use.

Schistosomiasis Sustained Control Program in Ethnic Groups Around Ninefescha (Eastern Senegal).

Schistosomiasis is the second most significant parasitic disease in children in several African countries. For this purpose, the "Programme National de Lutte contre les Bilharzioses" (PNLB) was developed in partnership with the World Health Organization (WHO) to control this disease in Senegal. However, geographic isolation of Bedik ethnic groups challenged implementation of the key elements of the schistosomiasis program in eastern Senegal, and therefore, a hospital was established in Ninefescha to improve access to health care as well as laboratory support for this population.

Implementation of Organ Culture storage of donor corneas: a 3 year study of its impact on the corneal transplant wait list at the Lions New South Wales Eye Bank.

Organ Culture corneal storage offers an extended storage time and increased donor pool and tissue assessment opportunities. In September 2011, the Lions New South Wales Eye Bank (LNSWEB) moved from hypothermic storage to Organ Culture corneal storage. This study evaluates the impact of implementation of Organ Culture on donor eye retrieval and the corneal transplant waiting list over a 3 year period in NSW, Australia.
