特定用途向け集積回路を備える眼科デバイスおよび方法
Document Type and Number:
Japanese Patent JP2013534847
Kind Code:
A
Abstract:
Ophthalmic devices with dynamic electro-active elements offer variable optical power and/or depth of field that restore lost accommodation in individuals suffering from presbyopia or aphakia. An illustrative device senses physiological processes indicative of the accommodative response and actuates a dynamic electro-active element to provide the desired change in optical power and/or depth of field. The illustrative device includes two application-specific integrated circuits (ASICs) for processing the accommodative response and actuating the electro-active element: a high-voltage ASIC that steps up a low voltage from a power supply to a higher voltage suitable for actuating the electro-active element, and another ASIC that operates at low voltage (and therefore consumes little power) and controls the operating state of the high-voltage ASIC. Because each ASIC operates at the lowest possible voltage, the illustrative ophthalmic device dissipates less power than other ophthalmic devices.
