Abstract: A system, technique and material composition for use in correction of eye condition are disclosed. The system comprising a processing utility and an etching utility. The processing utility comprises: correction pattern module configured for providing a selected two-dimensional pattern in according with input data indicative of vision impermanent of a user, and for generating operational instructions for forming said selected two-dimensional pattern on the surface of the cornea by said etching utility. The etching utility is configured to etching the selected patter on surface of the cornea of a user. The material composition comprises aqueous solution comprising a plurality of nanoparticles, said nanoparticles comprising maghemite nanoparticles wrapped by biocompatible protein chains. The material composition may be used as eye drops thereby allowing the nanoparticles to occupy etched region on the cornea, thereby maintaining correction of eye condition.
