Nanotechnology is a new concept that will soon become the pinnacle of science and technology. It penetrates using nanometer-sized molecules and has demonstrated its worth in space, medicine, and other fields of science. Because the eye is a small organ that can be easily accessed due to its exposed location, it is an ideal target for nanotechnology. It appears that the "discovery of nanomedicines has reawakened huge aspirations for ophthalmic pharmacotherapy, in which nanostructured drugs are predicted to pass through the eye's limiting barriers." Safe manufacturing procedures and unforeseen biological repercussions of nanomaterial use remain barriers to nanotechnology adoption. These challenges are not insurmountable, and this developing sector is likely to yield innovative treatments for ocular disorders.
