Endothelial keratoplasty (EK), also referred to as posterior lamellar keratoplasty, is a form of corneal transplantation during which the diseased inner layer of the cornea, the endothelium, is replaced with healthy donor tissue. Diseases that affect the endothelial layer include Fuchs' endothelial dystrophy, aphakic and pseudophakic bullous keratopathy (corneal edema following cataract extraction), and failure or rejection of a previous corneal transplant. The EndoSerter®-PL is a sterile, single use, handheld, manual ophthalmic surgical instrument. It is used to preload a processed donor corneal endothelial allograft for storage and transportation to the ophthalmic surgeon and to deliver the allograft into the anterior chamber of the eye during corneal surgery. It is designed to deliver a corneal endothelial allograft into the eye during corneal endothelial keratoplasty. The loading and storage of donor tissue for transport to the surgeon is performed by trained technician at the eye bank. Users of this graft insertion instrument for EK are trained ophthalmic surqeons in a healthcare facility or hospital. #### V. INDICATIONS FOR USE The indications for use statement for the EndoSerter®-PL by CorneaGen is: The EndoSerter®-PL is used to insert corneal endothelial allograft tissue measuring less than or equal to 8.0 mm in diameter and 100 microns in central thickness into the anterior chamber through a minimum 4 mm incision during endothelial keratoplasty procedures and for loading and storage of donor tissue during transport to the surgeon by trained eye bank technicians, and for storage of donor tissue for up to a maximum of 48 hours. The Indications for Use statement for the EndoSerter®-PL is not identical to the predicate or reference devices; however, the differences do not alter the intended therapeutic use of the device, nor do they affect the safety and/or effectiveness of the device relative to the predicate or reference devices. The subject, predicate, and reference devices have the same intended use for the insertion of corneal endothelial allograft tissue during endothelial keratoplasty procedures. {5}------------------------------------------------ ### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE AND REFERENCE DEVICES Graft Insertion for Endothelial Keratoplasty (EK) is the technological principle for both the subject and predicate as well as the reference devices. It is based on the use of insertion instrumentation for corneal tissue graft EK procedures. At a high level, the subject and predicate devices and when appropriate the reference device are based on the following same technological elements: - . Same mode of operation in the insertion of corneal endothelial graft for patients requiring Endothelial Keratoplasty (EK) - Used for loading and storage of donor tissue during transport . - Delivers a circular endothelial tissue button in a rolled configuration . - . Provided as a sterile, single use, disposable device - Loaded by trained technicians at the eye bank . - . Donor posterior lamellar endothelial graft of central corneal thickness of 100 microns The following technological differences exist between the subject and predicate devices: - . Minimum 4 mm incision for the subjective device and 5.1 mm or larger incision for the predicate device. However, the subject device and the reference device are the same in terms of incision size of minimum 4 mm incision. - Insertion of corneal endothelial allograft tissue measuring less than or equal to . 8.0 mm and the predicate and reference device requiring the insertion of donor tissue diameter of less than or equal to 8.5 mm. This difference of 0.50 mm graft size is negligible and does not introduce any potential impact to safety and/or effectiveness. - Subject device is manufactured using polycarbonate, isoplast, polyimide, ● stainless steel, silicone, acrylonitrile butadiene styrene (ABS), white, blue, and black colorant. Manufacturing materials for the predicate device is not commercially available or available in public records. The reference device is manufactured using polycarbonate, isoplast, polyimide, stainless steel, white, blue, and black colorant. The addition of silicone and ABS does not introduce any {6}------------------------------------------------ impact to safety and/or effectiveness based upon biocompatibility testing performed in accordance with ISO 10993-1. - . Subjective device has tissue storage capability up to 48 hours and the predicate device has tissue storage capability up to 72 hours. This difference does not introduce any potential impact to the safety and/or effectiveness of the subject device in delivering the allograft, and relevant testing has confirmed the stability of the subjective device during tissue handling and stability testing. #### VII. PERFORMANCE DATA The following performance data were provided in support of the substantial equivalence determination. ## Biocompatibility Testing The biocompatibility evaluation for the EndoSerter®-PL device was conducted in accordance with the FDA Guidance issued on September 4, 2020 "Use of International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process"." The battery of testing included the following tests which demonstrated biocompatibility of the device with direct contact to the human tissue: - Cytotoxicity ● - Sensitization - Irritation ● - Acute Systemic toxicity ● - . Pyrogenicity The EndoSerter®-PL device is considered tissue contacting for a duration of less than 24 hours, while the allograft tissue is considered a permanent implant. ## Tissue Handling and Stability Testing The purpose of this study was to quantitatively determine the endothelial cell damage (endothelial cell loss) when using the EndoSerter®-PL to load, store, transport, and deliver donor allograft tissue. The test results demonstrated that the device did not have any leaking, damage, or shifting of the tissue grafts during the transportation and storage. {7}------------------------------------------------ # Sterilization Validation The purpose of this study was to adopt, by equivalency, the EndoSerter®-PL into the existing radiation sterilization process used for the EndoSerter®. The radiation sterilization dose range provided a Sterility Assurance Level (SAL) of 10° in accordance with FDA Guidance issued on January 21, 2016 "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile". # Shelf Life and Transportation Testing The purpose of this study was to perform leak test to demonstrate that the EndoSerter® PL does not leak corneal storage media during storage and transportation over a 48hour period prior to and after accelerated aging. The results of this leak test validated that storage media did not leak from the EndoSerter®-PL during storage and transportation over a 48-hour period prior to and after accelerated aging. # Aseptic Handling Testing This testing, performed in accordance with the USP<71>. Method Suitability Test procedures, was conducted to demonstrate the ability to maintain aseptic handling of tissue without increased risk of contamination on transfer to and storage in the EndoSerter®-PL. The testing results demonstrated that the aseptic handling utilized by CorneaGen to load and transport cornea tissue in the EndoSerter®-PL did not increase the risk of contamination of the tissue. # Dimensional, Functional, and Mechanical Testing The purpose of this study was to perform dimensional, and mechanical testing utilizing measurement of critical dimensions including additional dimensions relating to mating components, visual inspection, and fit of those components. The study confirmed that the EndoSerter®-PL components perform mechanically and functionally as designed. Therefore, supporting the acceptable use of the device components and materials required in the design and assembly of the EndoSerter®-PL. #### VIII. CONCLUSION The EndoSerter®-PL, the subject device, is substantially equivalent to both the predicate and the reference devices' intended use which includes: - same mode of operation in the insertion of corneal endothelial graft for patients ● requiring Endothelial Keratoplasty (EK) {8}------------------------------------------------ - . used for loading and storage of donor tissue during transport - delivering a circular endothelial tissue button in a rolled configuration . - provided as a sterile, single use, disposable device ● - . loaded by trained technicians at the eye bank - . posterior lamellar endothelial graft of central corneal thickness of 100 microns corneal thickness, as well as the duration of time that tissue can be stored within the device. The minimal technological differences of EndoSerter®-PL, the subject device, to the predicate and the reference devices, do not pose any potential impact to safety and/or effectiveness as demonstrated by the performance testing conducted.
