Drug Delivery Systems for treating the eye are becoming more sophisticated and the requirements on the customised machinery to manufacture them are becoming that much more challenging. The projectionsÂ are for increased call for such treatments owing to longer life expectancies and more economically active urban Asian population, while the requirement in the Third World remains huge.
Conditions that could already result in the loss of an eye, and the relative isolation of the blood-retinal barrier mean that there is a perceived lower (but still high) regulatory environment for innovative ophthalmic drug deliveryÂ systems. Harro HÃ¶fliger find themselves well placed to industrialise such drug delivery systems. As they point out in the Eyecare Machinery Segment, â€We have been supplying depot and implant assembly machines for to the now ISO Class 2 clean room standards for 20 years.”
Another class of ophthalmic therapy coming on stream isÂ impregnated contact lenses and here too Harro Hofliger have supplied many contact lens lines, with their complex hydration and inspection systems, which are virtually production lines in their own right.
Ophthalmic nano-particle drug delivery systems only need to look to Harro Hofligerâ€™s specialised aseptic powder dosing system, suitable for dosing sub 1 mg doses.
