 The Scleral Lens Education Society (SLS) teaches contact lens practitioners the science and art of prescribing scleral contact lenses. SLS supports public education that highlights the benefits and availability of scleral contact lenses.

The International Society ofContact Lens Specialists (ISCLS) has elected Perth optometrist Damon Ezekiel asits President, reflecting the first time the leadership of the 65-year-oldorganisation has been awarded to an Australian.


The ISCLS, the world’s firstinternational contact lens society, comprises pioneers and global leaders inthe practice, development and advancement of contact lenses.


Damon, owner of Ezekiel Eyes inNedlands Perth, took over as President at the Society’s 46th Congress inWashington DC recently.


Alsoat the Congress, Damon and British optometrist, Caroline Hodd, were awarded theprestigious Herschel Medal*, given “in recognition of outstanding originalcontributions to contact lens design techniques and of fitting and applicationin clinical practice, in the education of students and in the advancement ofthe status of contact lens practice”. Caroline is the only woman to ever designand market a contact lens to help people with unusual eye conditions.


Damon’s father, Don Ezekiel, Memberof the Order of Australia, contact lens inventor and now retired Perth optometristwas awarded the Herschel Medal in 2005. Don invented and produced the world’sfirst gas permeable scleral contact lens.


Damon said he was proud andhumbled to be elected President of the ISCLS. “The ISCLS reflects the best ofthe best in contact lens practice around the world; these are the men and womenwho wrote many of the textbooks students now use. They are practitioners whohave revolutionised the treatment of eye conditions, and their work hasimproved the quality of life of thousands of patients over many decades,” hesaid.


In addition to owning andmanaging Ezekiel Eyes, Damon is a contact lens consultant to researchorganisations and lectures and conducts workshops in contact lens practice,including the fitting of all types of rigid gas permeable contact lenses,including Orthokeratology, scleral lenses and soft bifocal, multi-focal andcosmetic contact lenses. He undertakes voluntary work in Vietnam and Cambodiaon behalf of eye charity Sight For All.


About the ISCLS


The ISCLS had its genesis in 1938with a meeting of minds of British optometrist Frank Dickinson and GermanWilhelm Söhnges. While WWII interrupted theircollaborations, they met again in 1951 in London, where they were joinedAmerican Jack Neill. All three were working on similar ideas, so they pooledtheir resources and launched the micro-corneal lens in 1952. Söhnges bought a house in Bavaria and it became a centre wherecontact lens practitioners from around the world could meet in a socialatmosphere and discuss mutual challenges and ideas. Since that time, the ISCLShas grown to become a leading global authority on contact lenses and comprisesmembers from around the world.


*The Herschel Medal is namedafter English astronomer Sir John Herschel, who first proposed the idea ofmaking a mold of a person’s eyes, to enable the production of corrective lensesthat could conform to the front surface of the eye.

 Definition of scleral lenses and guidelines for diameter selection


The evolution of scleral lenses has led to new formulations of scleral fitting concepts and designs. The diameters of modern scleral lenses have been overhauled too and they are smaller comparing to the original ones. Nowadays, prescription of mini-sclerals supposedly seems in major extension and it appears indeed the necessity of some practitioner to differentiate the smaller mini-scleral lenses from larger mini-scleral lenses empathizing that they are the “smaller” ones. Therefore, it is maybe, necessary a definition of mini-scleral lenses referring to the landing zone width in relation to the horizontal visible iris diameter (HVID) and the limbus extension. The choice of the total diameter is crucial for a successful fitting and it depends majorly on patient’s topographic patterns and anatomic factors. However, there are other important criteria for the selection of the scleral lens diameter based on oxygen supply, bubbles formation, mechanical stress on a toric sclera, ocular surface disease protection, entity of the vault over the cornea and distribution of the lens weight on the sclera. The advantages of mini-scleral lenses are various nonetheless in some cases large lenses are necessary. This paper presents a review of the benefits and disadvantages of both mini and large scleral lenses analyzing the conditions in which it may be better to prefer one diameter to another. A suggestion may be that to start fitting the smallest lens as possible, depending on the dimension of HVID and limbus width and consider larger lenses only when issues occur.
