HHS Vulnerability Disclosure, Help 2012. One of the challenges with silicone hydrogel cast moulded lenses is to achieve complete closure of the mould and not allow any leakage of material at the edges.

Ocular physiology and comfort in neophyte subjects fitted with daily disposable silicone hydrogel contact lenses. Nichols J. The majority of soft lenses, including disposable lenses, are made from hydrogel. These lenses still show a decrease in modulus with higher water content, but break the traditional inverse relationship between Dk and water content by having a higher Dk than water content predicts as can be seen in Figure 1.
