Research student, Yr Ysgol Optometreg a Gwyddorau'r Golwg
I completed my Master's degree by research in visual electrophysiology at the University of New South Wales, Sydney Australia in 2010. In addition, One of my supervisors was from the Australian National University, one of the top-ranked research-intensive Universities in Australia and the world. I am currently pursuing a PhD project investigating different protocols to stabilise the cornea by crosslinking, in collaboration with Mr David O'Brart (St. Thomas' Hospital, London).

I have been an Advisor or Supervisor for three undergraduate students with different special areas in King Saud Universit. The titles of their projects are:
- Central Corneal Thickness and Corneal Endothelial Cell Changes Caused by Contact Lens Use
- Ocular Parameters in Dominant Compared with Nondominant Eyes
- A Comparison of the Effectiveness of Refresh Plus Vs. Viscotears In People Who Have a Computer Vision Syndrome
The first two were nominated to King Saud University Scientific research award out of 2000 students, one of them was awarded the second place in 2012.
My undergraduate teaching also included lectures and lab classes in the Optometry Department with different courses such as:
- Anomalies of Binocular Vision
- Clinical Methods I
- Clinical Methods II
- Visual Science II
- Optometric Practice
- Contact Lenses I
- Occupational Vision
- Clinical Examination of the visual system III
- Ophthalmic Optics and Dispensing I

Research Topics and Related Projects:
A new method has been introduced for the treatment of progressive keratoconus using collagen crosslinking. Under topical anaesthesia, the epithelium of the cornea is removed or partially scratched, riboflavin is applied and the cornea is exposed to ultraviolet A-light (UVA, 365nm) for a duration of 30 minutes. This method results in crosslinking of the constituent molecules of the cornea, thereby increasing its strength by up to 300%. Despite its widespread clinical use, very little is known about how stability is conferred and, in particular, at what structural level crosslinking occurs. Some studies used X-ray scattering showed that molecular collagen structure is not affected by riboflavin/UVA crosslinking treatment. This led us to hypothesize that the crosslinking occurs between the surfaces of the collagen fibrils and the surrounding matrix. In addition, Meek and his colleague used absorption measurements to show that, contrary to some opinion, it is necessary to remove the epithelium to allow penetration of the riboflavin into the corneal stroma and that, although partial epithelial removal allows some penetration, this is uneven, and so is not a promising approach. This study will investigate other novel techniques to carry out crosslinking without epithelial removal.
