Prescribing soft contact lenses for astigmatism
, 2009 There have been continued improvements in toric soft lens design over the past three decades. Data that we have gathered from annual contact lens fitting surveys demonstrate a commensurate increase in toric lens fitting as a proportion of all soft lenses

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities
Advanced Functional Materials, EarlyView.We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Conjunctivochalasis and Contact Lenses
American Journal of Ophthalmology, 2009 To assess the relationship between age and the incidence and severity of conjunctivochalasis in contact lens (CL) wearers by grading of conjunctivochalasis, and to compare the severity of conjunctivochalasis between CL wearers and nonwearers.Prospective, nonrandomized consecutive case study.A total of 600 CL wearers (94 hard CLs [HCL] and 506 soft CLs [

Advanced Functional Materials, EarlyView.For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Comparison of accommodation with rigid and flexible contact lenses [PDF]
, 1977 Measurements were made of the amplitude of accommodation for myopes wearing spectacles, rigid contact lenses, and flexible contact lenses. Both forms of contact lenses placed greater accommodative requirements on the myope than did spectacle correction ...

Advanced Functional Materials, EarlyView.Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...
