Biographical entry Ezekiel, Donald (Don) (1936 - )

12 September 1936


Donald Ezekiel is an optometrist and innovator in the design and manufacture of contact lenses. After qualifying he worked in family practice and had several years clinical experience in the United Kingdom, where he gained his Diploma in Contact Lens Practice. Returning to Perth in 1970 he established his own practice and purchased the necessary equipment to make contact lenses. His company, Gelflex Laboratories, manufactured soft and hard lenses for over 40 years before being sold. Ezekiel's innovations include the use of rigid gas permeable materials for scleral lenses which allowed greater corneal oxygenation: the lenses therefore could be worn for longer. With Graham Barrett he developed what was reputedly the world's first foldable intraocular lens made from a hydrogel material, the key advantage of which was that a smaller limbal incision was needed to insert the lens into the eye. He has also worked on the development of a soft translating bifocal contact lens.
