Compromises’ End? The introduction of a silicone hydrogel daily disposable lens As we rapidly approach the tenth anniversary of the introduction of silicone hydrogel lens materials, it is apparent from both clinical experience and information obtained from many controlled scientific studies that such materials provide huge benefits to our patients. Hypoxic issues such as epithelial microcysts, stromal striae, endothelial polymegethism, limbal hyperemia, neovascularisation and myopic creep are all markedly reduced or reversed with these materials... more		Imagine you have a happy, compliant patient Imagine you have a happy, compliant patient. They have worn contact lenses for many years. Very few complications. They also have glasses that they are happy to wear, doing so at least one day per week and at the end of each day before they go to bed. The corneas are normal – tear film, epithelium and endothelium look good. There is a little bit of limbal injection but nothing clinically significant. The upper lids are smooth. The patient even reports, when asked, that their lenses are comfortable. more

The Use of SiH Contact Lenses by Canadian Optometrists 2000–2006 Purpose: To evaluate the contact lens fitting preferences of Canadian optometrists over the period 2000 – 2006, to determine the trends in fitting that occur as new lens types and modalities are released into the market. Methods: 1000 Canadian optometrists were surveyed annually over a 7 year period (2000-2006), resulting in 7000 optometrists in total being surveyed. Surveys requested information about the next 10 patients fit with contact lenses and which contact lens solutions were dispensed. more		ARVO Synopsis V.E. Evans (Institute for Eye Research, University of New South Wales) and colleagues investigated factors associated with discontinuation of silicone hydrogel daily wear by conducting a retrospective, case-controlled analysis of various combinations of silicone hydrogel lenses and peroxide-, PHMB- and polyquad-based lens care regimens. Results showed that discontinuations were more likely to be related to subjective comfort than adverse events. Indicators for drop-out from lens wear included poor comfort, dryness, self-reported redness, self-reported poor vision and reduced wear time. more
