Limbal ring CLs magnify the eye appearance and this is achieved by adding pigments to these lenses. Federal government websites often end in .gov or .mil. The most common types of contact lenses are hydrogel and silicone hydrogel, known as soft contact lenses. Silicone hydrogel lenses are a more porous type of soft contact lens than regular hydrogel lenses, allowing more oxygen to enter the cornea. Cont Lens Anterior Eye 2013;36:164-70.43.

The company says these lenses maintain 95% of their moisture for up to 16 hours.31 Bausch + Lombs website say the two-phase manufacturing process of these lenses retains moisture and delivers a highly wettable surface. Clinical performance of three silicone hydrogel daily disposable lenses. 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. Initially, these lenses will be available in plano to -4.25D (in 0.25D steps) with cylinder powers of -0.75D and -1.25D and the full range will be available later this year.
