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. Contact lens factors including centration, movement and deposits were assessed. The pioneering first generation lenses, PUREVISION Vision (balafilcon A, Bausch & Lomb) and NIGHT & DAY (lotrafilcon A, CIBA VISION), were introduced into the contact lens market almost 10 years ago and continue to perform well. Lately, the market has seen a huge increase in the sales of limbal ring CLs. In comparison, lotrafilcon B has a higher water content of 33 percent and a Dk of 110 units. Subjective ratings (1-10 scale), adverse events (percentage of Px), physiological variables (0-4 scale), and wearing time were collected at each visit and compared between groups.

Lenses grouped into SiHy (delefilcon A, somofilcon A, narafilcon A) and Hy (omafilcon A, nelfilcon A). 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. https://synergeyes.com/professional/specialty-contact-lenses-scleral-vs/. The most common types of contact lenses are hydrogel and silicone hydrogel, known as soft contact lenses. Jones L, Subbaraman L, Rogers R, Dumbleton K. Surface treatment, wetting and modulus of silicone hydrogels. Edge and lens quality is paramount, which may present difficulties with new technologies. These findings suggest that choice of material is a patient and practitioner preference; however, for patients at risk of hypoxia-related complications, SiHy materials should be considered.
