Device Co-Developed by San Diego Eye Doctor May Improve Corneal Transplant Success Rates

Dr. David J. Schanzlin Performs the First Endothelial Keratoplasty Surgery Using the New EK Injector, the Only Device Created to Store, Transport, and Inject Corneal Transplant Tissue

SAN DIEGO, CA -- (Marketwired) -- 01/16/14 -- David J. Schanzlin, MD of Gordon-Weiss-Schanzlin Vision Institute in La Jolla recently performed the first corneal transplant for endothelial keratoplasty using the newly developed EK Injector from TDAK Medical Inc.

The device, which is approved by the U.S. Food and Drug Administration, was developed as a collaboration among TDAK Medical Inc. CEO Tom Trozera, PhD, Dr. Schanzlin, and several physicians at the University of California-San Diego. Dr. Schanzlin, who is also President of the San Diego Eye Bank® says: "There have been other people who have tried to develop ways to put this tissue into the eye. Nobody, though, has developed something that can be used at the eye bank where the tissue is pre-cut and loaded. We're able to ship the tissue anywhere in the world in these injectors."

For individuals affected by endothelial diseases, such as Fuchs' dystrophy, endothelial keratoplasty (EK) refers to transplant techniques designed to spare a patient's cornea, the clear, dome-shaped surface that covers the front of the eye. During EK surgery, ophthalmologists replace only the diseased or damaged innermost layer of cells, known as the endothelium. "In the 1950's, as corneal transplantation came about, we would treat patients with a full-thickness corneal transplant," says Dr. Schanzlin. "It would restore their sight, but it would change the refraction. Patients would have a lot of astigmatism, they would need contact lenses, and they had a greater rejection of the transplant when they did the full transplant."

In a recent blog post, "Dr. Schanzlin and Colleagues Introduce New Corneal Transplant Device," the ophthalmologist explains how EK surgery developed in place of full-thickness corneal transplants -- as well as some of the obstacles patients and doctors still face today regarding the procedure. The EK Injector is meant to reduce such obstacles due to its ability to store, transport, and inject tissue, notes Dr. Schanzlin.

Dr. Schanzlin says traditional EK surgery uses a folding technique. Surgeons cut the tissue using a round blade, called a trephine, then transfer the tissue and unfold it in the eye. However, in many cases, Dr. Schanzlin says cell damage and/or complications with the transfer of tissue occur. He notes that the innovative design of the EK Injector minimizes the surgeon's time in the eye, significantly reduces the loss of endothelial cells during surgery, and simplifies the eye bank's process for handling the tissue.

"The real unique feature in this is that all the tissue processing is done in the operating room," says Dr. Schanzlin. "The cornea is loaded into the injector and the doctor merely has to open an entry point and inject this endothelial keratoplasty button into the eye. It saves the patient time, it saves the doctor a lot of time, and ensures that there's less wasting of tissue because of the doctor folding it incorrectly, or other problems that could result."

The San Diego Eye Bank® also recently finalized a contract with Trozera in which TDAK Medical Inc. serves as the exclusive distributor of EK injectors. "It is very rewarding to bring this innovative technology to the market to help improve patients' outcomes," says Dr. Schanzlin. Dr. Schanzlin also says that he's pleased to be able to partner with both the eye bank and TDAK to bring this device to surgeons around the country, and to advance the ability to perform endothelial transplants.

The broad selection of hardware, the rapid evolution of operating systems and the time-to-market for mobile apps has been so rapid that new challenges for developers and engineers arise every day. Security, testing, hosting, and other metrics have to be considered through the process. In his session at Big Data Expo, Walter Maguire, Chief Field Technologist, HP Big Data Group, at Hewlett-Packard, will discuss the challenges faced by developers and a composite Big Data applications builder, focusing on how to help solve the problems that developers are continuously battling.
As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...

Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated and cloud solutions through hybrid hosting – a sustainable solution for the data required to manage I...
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...

Who are you? How do you introduce yourself? Do you use a name, or do you greet a friend by the last four digits of his social security number? Assuming you don’t, why are we content to associate our identity with 10 random digits assigned by our phone company? Identity is an issue that affects everyone, but as individuals we don’t spend a lot of time thinking about it. In his session at @ThingsExpo, Ben Klang, Founder & President of Mojo Lingo, will discuss the impact of technology on identity. Should we federate, or not? How should identity be secured?

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
