Methods: Lotrafilcon A, comfilcon A, somofilcon A, senofilcon A, and lotrafilcon B silicone hydrogel contact lenses were plasma coated with acrylic acid followed by Mel4 antimicrobial peptide immobilization by covalent coupling. The objective of the study is to compare the overall subjective comfort profile over 8 hours of lens wear in two groups of habitual soft contact lens wearers (daily disposable hydrogel lenses and frequent replacement lenses) when refitted in to somofilcon A lenses. Silicone hydrogel contact lenses were first introduced in late 1999 1 with the ability to supply sufficient oxygen to the cornea during overnight wear, thus making extended wear possible. 33,34 Current ScCLs are manufactured using high Dk materials (e.g., fluorosilicone acrylate).

This material now accounts for approximately 55% of all soft lens fits worldwide and 62% in the United States.7 Its increased oxygen transmissibility promised a reduction in the rate of corneal infections, but research shows the risk of microbial keratitis is similar regardless of lens material studied.8-12 In fact, several studies show that SiHy materials doubled the relative risk for infiltrative events.13-16 Studies also suggest that older generation SiHy materials provided only a minimal increase in comfort over conventional hydrogel (CH) materials.5,17 This was due to the incorporation of siloxane groups into SiHy lenses, which made them more hydrophobic and stiffer than CH materials, but led to issues related to poor lens wettability and mechanical complications.18-20 These mechanical complications included mucin balls (Figure 1), corneal erosions (Figure 2), superior epithelial arcuate lesions (Figure 3), epithelial flaps and CL-associated papillary conjunctivitis.21-26 The hydrophobic nature of certain SiHy materials tends to deposit high levels of certain lipids and increased denatured protein.27,28 Hence, several practitioners still choose to fit CH materials. 1257 0 obj <>stream In 1938 perspex (polymethylmethacrylate, or PMMA) began to replace glass in contact lens manufacture.
