NIIOS 20 years anniversary

In 2000 the Netherlands Institute for Innovative Ocular Surgery (NIIOS) was established by Dr. Gerrit Melles. We are an independent organization that innovates in ophthalmic surgery and for more than 20 years, NIIOS is dedicated to innovations in corneal surgery. In particular, NIIOS developed and refines techniques to transplant the cornea in conditions such as Fuch’s endothelial dystrophy, keratoconus and bullous keratopathy. These techniques, which have been the foundation of NIIOS, are now increasingly being adopted worldwide. NIIOS consists of four organizations that work closely together and complement each other:

  • NIIOS Research and Development
  • Amnitrans EyeBank Rotterdam
  • Melles Cornea Clinic Rotterdam
  • NIIOS Academy

As we all know, 2020 is a very turbulent year, also for us at NIIOS. However, we would like to continue to develop and innovate. For example, we hosted the first NIIOS Cornea Evening – Live Online broadcasted from Rotterdam. Since our first NIIOS Cornea Evening – Live Online was a big success, we will be hosting a second NIIOS Cornea Evening – Live Online on the 21st of November 2020!


We have a new Instagram page for our Cornea Clinic, follow us now (@melleshoornvlieskliniek)

That results in our doctors being able to pay more attention to your care and needs as a patient.
