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. That is why for most silicone hydrogels, higher water content is associated with lower Dk. Atchison D. Optical models for human myopic eyes. With these lenses we see a higher Dk with higher water content than would be expected with first generation lenses, and correspondingly lower modulus, related to the higher water content.

Traditionally we have seen adverse events likely to be at least in part mechanically induced in silicone hydrogel extended wear, such as superior epithelial arcuate lesions, [5] corneal erosions [6] and contact lens papillary conjunctivitis. With the 3rd generation, a unique group of materials present themselves, despite their differences. 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. Asian patients corneas have a smaller horizontal visible iris diameter and are more prolate with a smaller palpebral fissure than Caucasians corneas. Clin Ophthalmol. Contact lenses 2016 a status quo remains for much of the contact lens industry.
