A diffusion cell for ex-vivo transcorneal drug penetration studies. The diffusion cell design enables control of the pressure and the flow in the acceptor chamber, and can be used for in-vitro studies of the effect of intraocular pressure on transcorneal drug penetration. Validation tests were...http://www.google.co.uk/patents/US5789240?utm_source=gb-gplus-sharePatent US5789240 - Diffusion cell for ex-vivo pressure-controlled transcorneal drug penetration studies
