Soft Contact Lenses
Soft contact lenses are
hydrophilic or "water loving". Their water content ranges
from 38% to 75% for different applications. They provide increasing
oxygen transmission but less durability as the water content raises.
Soft contact lenses offer
the following advantages:
- comfortable
- quick adaptation to
wearing
- flexible wearing times
- correction of most vision
problems
- simple and easy care
& hygiene
- ability to change or
enhance eye colour.
Soft contact lenses are available as conventional
lenses which usually last for 12 to 18 months using a care system
which usually consists of separate solutions for cleaning, rinsing,
disinfection & storage. They are now also available as disposable
soft lenses, daily-disposable
lenses and as tinted
soft lenses.
Part or all of the cost of contact lenses is covered
by your Health Fund if you have private
health insurance.
Rigid Contact Lenses
Rigid, or hard, contact
lenses are less comfortable initially but do offer specific advantages
for some eye and vision problems:
- able to correct some
problems which cannot be treated with soft lenses.
- more durable and longer
life.
- able to correct some
cases of astigmatism without requiring more expensive lens designs.
Your optometrist will advise
you which contact lens type is most appropriate for you.
Disposable Contact Lenses
Disposable contact lenses are a sub-group within
soft contact lenses. They provide improved eye health by the planned
replacement of lenses before problems with lens aging and deposits
can develop. These lenses have been made possible by improved methods
of production which have lowered the cost to a point where disposability
is affordable.
Different types of disposable contact lenses are
replaced on a schedule of 1 week, 2 weeks, 1 month or 3 months.
Since the lenses do not have to last so long,
the care and cleaning procedures are much simpler and are usually
based upon a convenient 1-bottle system for cleaning, disinfection
& storage.
They are now also available in tintedoptions and
as a daily-disposable.
Daily Disposable Contact Lenses
Disposable contact lenses have now progressed
to the ultimate in disposability: Daily-disposables. These are worn
once and discarded. There are no solutions required since the lenses
never need to be stored.
Daily disposable contact lenses are proving especially
popular with people who want to wear them as an occasional option
for social wear or sport.
Tinted & Coloured Contact Lenses
Soft contact lenses are also available in tints
and colours. These fall in to 3 main categories:
VISIBILITY TINTS
to make it easier to see and handle the contact lenses. These are
usually a pale blue and included in the lenses at no extra charge
TRANSPARENT TINTS
which are used to work with and enhance the patient's own natural
eye colour. For example: to make a hazel eye greener
COSMETIC TINTS which
are used to cover and completely change the patients own eye colour.
For example: to make brown eyes blue.
New Research in Contact Lenses
Contact lenses are an exciting
and rapidly developing part of optometry. As examples, the following
projects are underway and showing promises results at research facilities
around the world:
EXTENDED WEAR CONTACT LENSES:
New safer lenses which can be worn for up to 30 days without lens
removal or cleaning. patients can sleep in these lenses and awake
to clear vision 24 hours a day. These new lenses are made possible
by new lens materials and improved knowledge about the eye's physiological
response during sleep.
BIFOCAL CONTACT LENSES:
It has always been difficult to produce a contact lens which can
provide distance and near prescriptions and move to the correct
area reliably for different tasks. Now new optic designs based upon
aspheric geometries are making this possible.
SIMPLER CARE SYSTEMS
LESS EXPENSIVE DAILY-DISPOSABLES:
Made possible by improvements to the mass production techniques.
New and exciting developments in contact-lens
technology are rapidly solving more and more vision problems. Even
bifocal contact-lens are now available. If your vision cannot yet
be corrected by lens or laser
technology, tomorrows realisation
of todays ideas may offer hope.
Contact lenses are now available in a rainbow
of colours,
some lenses now offer UV-ray protection and contain materials that
combat "dry eye" problems. Contacts also come in disposable,
long-term use (12 to 18 months) and rigid gas-permeable
formats (the latter allows gases to flow although the lens, rather
than being trapped next to the eye).
Cooperative Research Centre for Eye Research and
Technology
Australian research facilities such as the Sydney
bases Cooperative Research Centre for Eye Research and Technology
(CRCERT) are at the forefront of exciting new developments in contact-lens
technology. Funded by a range of corporations, CRCERT also conducts
eye-care training in Asia and the Middle East.
Combining expertise from NSW University, the University
of Wester Sydney, the CSIRO, the Victorian College of Optometry,
the Queensland University of Technology and the Optometric Vision
Research Foundation, CRCERT has worked with CIBA Vision to produce
a revolutionary new Extended Wear Lens. Designed for continuous
day and night wear for one month, the development ends the need
for daily contact lens insertion, removal and care. This research
now has the potential to earn Australia a multi-million-dollar income.
Implanted Contact Lenses
Another ground-breaking contact-lens development
is currently being trialed in Australia. The US-developed lens can
be permanently implanted by micro-surgery. (Should post-operative
complications occur, the lens can be removed.)
When finalised, the permanent lens will offer
great lifestyle advantages over current contact-lens options. Wearers
will no longer need to wear goggles in the surf or worry about their
contacts falling out.
Technology Breakthrough
Ciba Vision contact lens company has released
a new extended wear lens to a limited number of practices in Australia.
We have been chosen as one of these practices and are delighted
to be fitting this state of the art contact lens.
The development of a safe and comfortable extended
wear contact lens has been the aim of contact lens scientists for
many years, and it looks like this goal has been reached at last.

The big breakthrough has been the development
of a contact lens material that allows healthy quantities of oxygen
to reach the eye, even during sleep. Focus Night & Day provides
up to 6 times the oxygen transmission of other contact lenses!
For suitable patients the benefits of extended
wear have arrived. Contact lens wear will be much more convenient
with less need to carry cases and solutions everywhere, no need
to plan for lens removal late at night and of course great savings
on cleaning and disinfecting solutions.
If you are interested please contact us on our
practice phone number to discuss this exciting breakthrough and
your suitability.
