Nanotechnology refers
broadly to a field of applied science and technology whose unifying theme is
the control of matter on the molecular level in scales smaller than 1
micrometer, normally 1 to 100 nanometers, and the fabrication of devices within
that size range. Nanotechnology is being widely used in the health professions
to treat various disease conditions. nanotechnology in medicine involves the
application of nanoparticles to make repairs at the cellular level. The use of
nanotechnologies in medicine offers many exhilarating possibilities and could
revolutionize the way we detect and treat damage to the human body and diseases
in the future. Nan medicine is a relatively new field in science and technology
but there have been trials which proved to be very effective. Nanotechnology is
widely used in the field of ophthalmology and it can do wonders for children
with poor vision.
Treating a child with
poor vision problems can be very different from treating an adult. The
procedures that are to be followed will be different in both cases. Due to this
reason nanotechnology is used to resolve the difficulties that the children
have to face during treatment and recovery. One of the benefits of using
nanotechnology for children is that it can improve the drug delivery process.
In nanotechnology nano particles are used for site specific drug delivery. In
this technique the required drug dose is used and the side effects are lowered
significantly as the active agent is deposited in the morbid region only. This
approach helps to reduce cost and pain to the patients. The nano particles used
in drug delivery are made up of nano scale molecules to improve the
bioavailability of the drug.
herapeutic treatment
such as eye drops, ointments, injections and implants have been the most the
most extensively used remedy for the ophthalmic diseases but it is often
disadvantaged by factors such as physiological barriers. Nanotechnologies being
used in these remedies helps to improve the quality of the treatments and gives
the patients a more pain free treatment. Nanotechnologies are being used in
other treatments such as contact lenses and medications which are used for
vision problems.
