Most hydrophilic IOLs are tumble polished after hydration which means polishing a soft surface rather than a hard glassy surface like pMMA. Generally, tumble polishing soft materials takes considerably more time than polishing hard materials. Benz developed a unique non-aqueous tumble polishing method to use with the Benz ILM technology to provide customers with dry-polished hydrophilic IOLs during the initial market development of their own hydrophilic IOL product line made from Benz IOL material. This polishing technology offers the benefits of fast polishing times, excellent surface quality and very high yields. Benz Dry Polishing Technology is available to our customers as a licensed technology product from Benz Research & Development.
