Welcome to Clinical Global Frontiers

Clinical Global Frontiers (CGF) was pioneered by a Filipino scientist, Victor Arni Sicam, Phd – who developed a new technology (granted U.S. and European patents [Patent No. WO2009127442A1]) in corneal imaging diagnostics useful for planning of cataract and refractive surgeries.

With the scientific culture as a basis for the formation of CGF, it is now a dynamic and visionary team with 34 years expertise internationally and locally in the Ophthalmic Industry. We specialize in innovative premium ophthalmic products and services, making it available to the Filipino community.

Currently, we are the exclusive distributor of products from Rayner (UK) and Cassini Technologies (The Netherlands). CGF operates with the mind-set that customer service is everyone’s job.

Victor Arni Sicam, PhD

Victor Arni Sicam, PhD

In 2007, I obtained PhD in Medical Physics at the VU University Medical Centre in Amsterdam. During my PhD studies I was able to develop a new technology in corneal imaging that eventually was granted European and US patents. This technology was later adopted by a start-up company, i-Optics, who developed the product and brought the novel corneal shape analyser, the Cassini, to the world market. As a pioneer in i-Optics I was involved in many aspects of the work including maintaining patent portfolio; organizing, designing and implementing clinical trials to the support the claims of the product; being active also in product development especially in developing new software features for the product. In the process, I was involved in scientific and commercial publications. It has brought me great accomplishment to experience the whole process “from bench to bedside” of applied technology in medicine.

To supplement my activities in i-Optics, I worked as a senior researcher at the Rotterdam Ophthalmic Institute of the Rotterdam Eye Hospital. I led a 2 year project funded by NutsOhra from 2012-2014 “Towards spectacle free outcomes in cataract refractive surgery”. This project produced results which were useful in promoting superior corneal diagnostics for astigmatism correction in refractive surgery. It also served as a catalyst to motivate multi-center studies on the Cassini which was presented in Ophthalmology Congresses in the US as well as in Europe. I also collaborated with the Optical Coherence Tomography group led by Johannes de Boer.
