First Corneal Transplant with Pre-loaded Donor Tissue Performed at Massachusetts Eye and Ear

08.05.2013
The first successful cornea transplant with donor endothelial tissue preloaded by an eye bank has been performed at Massachusetts Eye and Ear in Boston, Mass. Roberto Pineda II, M.D., Director of the Refractive Surgery Service at Mass. Eye and Ear, and an Associate Professor of Ophthalmology at Harvard Medical School, recently performed the groundbreaking transplant.
Dr. Pineda performed the surgery utilizing donor endothelial tissue that was prepared and pre-loaded into EndoGlide™ (Angiotech Pharmaceuticals, Inc.) cartridges at the Lions Eye Institute for Transplant & Research (LEITR) in Tampa, FL. According to Dr. Pineda, using preloaded donor tissue may minimize potential damage to the endothelial cells and, thus, may lead to better outcomes for the patient.

“Reducing any variables that could interfere with a patient’s ability to successfully regain sight after surgery is significant,” said Dr. Pineda. “The ultimate goal is to improve the quality of life for our patients,” Dr. Pineda said.

A world-leading cornea expert and refractive surgeon at Mass. Eye and Ear, Dr. Pineda has collaborated with LEITR and Angiotech/Sharpoint for the last seven months to help develop the innovative procedure.

“I am pleased that - with Dr. Pineda leading these efforts - Mass. Eye and Ear is at the forefront of implementing an innovative technology that could greatly improve the quality of surgical outcomes for patients facing partial or complete vision loss,” said Joan W. Miller, M.D., FARVO, Chief and Chair of Ophthalmology at Mass. Eye and Ear and Harvard Medical School.

Last year, LEITR reported that eye banks are able to safely prepare and load corneal tissue into the EndoGlide™ cartridges. In a pre-clinical study presented at the 2012 Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting, corneal buttons pre-loaded by LEITR sustained an average of 9.07% endothelial cell damage, compared to 36.2% endothelial cell damage in control group tissue that was loaded into the insertion system on site. The difference in endothelial damage between the preloaded and control buttons was statistically significant (P = 0.004).

About Massachusetts Eye and Ear
Mass. Eye and Ear clinicians and scientists are driven by a mission to find cures for blindness, deafness and diseases of the head and neck. After uniting with Schepens Eye Research Institute in 2011, Mass. Eye and Ear in Boston became the world's largest vision and hearing research center, offering hope and healing to patients everywhere through discovery and innovation. Mass. Eye and Ear is a Harvard Medical School teaching hospital and trains future medical leaders in ophthalmology and otolaryngology, through residency as well as clinical and research fellowships. Internationally acclaimed since its founding in 1824, Mass. Eye and Ear employs full-time, board-certified physicians who offer high-quality and affordable specialty care that ranges from the routine to the very complex. U.S. News & World Report’s “Best Hospitals Survey” has consistently ranked the Mass. Eye and Ear Departments of Otolaryngology and Ophthalmology as top five in the nation.

About Endothelial Keratoplasty (EK)
Endothelial Keratoplasty (EK) procedures allow surgeons to preserve the majority of a recipient's cornea while replacing the non-functioning or diseased inner portion of the cornea with a healthy donor tissue. EK procedures require small incisions and are more minimally invasive than Penetrating Keratoplasty (PK) procedures. Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) is a procedure offering minimal astigmatism and more rapid visual recovery, as compared to traditional PK procedures.

About the Lions Eye Institute for Transplant & Research (LEITR)
The Lions Eye Institute for Transplant & Research, Inc., (LEITR) is a nonprofit organization dedicated to the recovery, evaluation and distribution of eye tissue for transplantation, research and education. LEITR's Eye Bank, located in Tampa, FL., is the only combined eye bank and ocular research center in the world. Since its inception, it has brought the "Gift of Sight" to more than 55,000 men, women and children worldwide. For more information, visit www.lionseyeinstitute.org. LEITR is a proud member of Vision Share, a highly organized network of the most innovative and successful eye banks.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
