Using 3D-printed Corneas to Cure Corneal Blindness

Artificial, 3D-printed corneas is already showing great promise in helping cure a big issue today: corneal blindness. Corneal blindness is a problem faced by millions of people across the globe, with estimates placing figures around a staggering 28 million individuals diagnosed with corneal blindness. Research teams and innovators, like Pandorum Technologies, are working hard on developing functional corneal tissue, ready to be implanted.

Patients suffering from corneal blindness often experience a failure to produce critical components for their corneas, like collagen, which results in the cornea degrading. This degradation eventually leaves patients incapable of seeing until their cornea is totally replaced, creating an intense demand for corneal transplants. A demand which is far from being met by donor corneas. 3D-printed and artificial corneas show a clear path out of the donor shortage.

Pandorum Technologies' 3D-printed corneas to combat the cornea donor shortage

There is a desperate need for a method to develop functional corneal tissue. Pandorum Technologies, a start-up based out of Bangalore, India (a hub for innovation), is taking this challenge head-on. This group of engineers, biologists and researchers are on a clear path to develop 3D-printed corneas which are functional and ready to implant.

Pandorum Technologies take medical images of corneas, develop 3D models based on these images, and 3D-print the cornea models on their BIO X. These cornea models are printed using a custom bioink developed within the company. Naming their final product the “Corneal Lenticule”, this biofabricated construct mimics the shape and size of cornea and possesses all the physical and biological properties necessary for long-term integration with the body. In turn, the Pandorum team’s work has led to an effective solution to the lack of available donor corneas. This can help many patients suffering from corneal blindness regain their sense of sight. Complimenting the BIO X, the Pandorum team also leverages DLP-based bioprinting with the LUMEN X for prototyping and fine-tuning the geometric shapes of the Corneal Lenticule.

Implanting printed corneas - entering human trials in India and USA

Pandorum Technologies has already demonstrated serious success during in vitro testing and in animal models. It’s now time for their printed corneas to enter the important phase of human trials. It’s time to collect the essential proof needed to bring this treatment to live patients and to begin restoring the sight of humans across the world. These clinical trials will take place across multiple hospitals spanning both India and the United States.

3D Bioprinted Models for Cochlear Implant Evaluation

Dr. Ulises A. Aregueta Robles and his team, as well as many others, see some key drawbacks with the use of animal models: intra-animal differences, long study periods, and a difficulty with extrapolating the results to human tissue responses. To overcome these issues within testing neuromodulation devices, and provide an alternative to animal testing, the team has set out to develop in vitro human tissue models. Here, they have created a model of human scala tympani, which can be used for testing cochlear implants.

Bioprinting biofilms with GelMA

“What if our existing tests and methodologies for studying bacteria are fundamentally flawed?” Inspired by this question, the team from Karolinska Institutet set out to develop an AST that focuses specifically on biofilms and is widely applicable regardless of the bacteria type. To accomplish this, they had to first gain a comprehensive understanding of the intricate process of biofilm formation.

Making a Difference in Patient Care with 4D Bioprinting

Dr. Kaushik Chatterjee is a Professor at the Indian Institute of Science, Bangalore, specializing in Materials and Biomedical Engineering. With a Ph.D. in Bioengineering from the Pennsylvania State University, his research focuses on biomaterials, tissue engineering, 3D printing. Recognized with awards like the Young Scientist Award and the Ramanjuan Fellowship, Dr. Chatterjee’s work aims to revolutionize regenerative medicine.

Developing Hydrogels for Bioprinting Astrocytes

Dr. Anna Herland at KTH Royal Institute of Technology and Dr. Daniel Aili from Linköping University recognized the need to enable researchers to develop more biomemitic models of sophisticated brain-like structures such as the brain-blood-barrier (BBB) and the central nervous system. They also recognized the importance of mimicking the extracellular matrix (ECM) environment to develop accurate 3D models of the BBB. To achieve this, culturing astrocytes in 3D was a critical step.
