Spatial Homeotropic and Planar Liquid Crystal Alignment Patterning
Advanced Materials Interfaces, EarlyView.A voltage‐assisted two‐step photoalignment methodology achieves precise micro‐patterning of alternating planar and homeotropic liquid crystal domains. Applying an AC electric field during in situ laser illumination minimizes phase retardation, reducing the required exposure dose. This cooperative mechanism enables high‐resolution spatial patterning and

Contact lenses can induce stromal thinning [PDF]
, 1988 We examined 27 patients who had worn high water content hydrogel contact lenses in one eye only for an average of 62 ± 29 months (means ± SD). The stroma of the lens-wearing eye was found to be significantly thinner (p < 0.05) than that of the ...
