Infrared spectroscopy revealed modified absorption peaks, accordingly. Energy-dispersive x-ray (EDX) analysis and inductively coupled argon plasma atomic emission spectroscopy (ICP) confirmed silver lens depot concentrations and were employed to measured eluate concentrations, while visible spectrophotometry and ICP spectrometry monitored methylene blue and silver elution rates in static versus simulated eye-blinking conditions. The conclusions reached are that (1) initial drug uptake of surface modified lenses increased in this order: polymacon\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e James Fick\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639156129\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639156126\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/26\/2009\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 180\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.60lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.41d","brand":"James Fick","offers":[{"title":"Paperback","offer_id":47305523134719,"sku":"9783639156126","price":73.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_bb88ba90-33c9-4096-9724-7d3c68e9b438.jpg?v=1758831115","url":"https:\/\/www.whiterainbookhouse.com\/products\/customized-contact-lens-treatments-for-james-fick-9783639156126","provider":"WR Book House","version":"1.0","type":"link"}
