Designing the Lenswave
The digitally acquired
data map derived from the topographic image is transferred to the
Wave Custom Contact Software. This software is then used to design
a custom lens that follows the contour of your cornea. Furthermore, the contact
lens can be configured to float on a layer of tears making it extremely
comfortable. The back surface of the custom contact lens can be varied every ten
microns (0.010 mm) allowing a lens to be designed for a variety of normal and
abnormal conditions. The Wave lens is fabricated on the
Optoform 40, a
state-of-the-art robotic lathe.
This is an example of a contact lens that can be designed using the
Wave Custom Contact Lens
software. This lens is characterized by not only correcting distance
vision, but near and intermediate vision as well, using
Treating Corneal Pathology
Keratoconus is a genetic condition that results in the abnormal
development of the cornea. The definitive treatment is a
However, using the Wave Contact Lens System, a contact lens can be
designed to provide excellent vision and comfort in the early to moderate phases
of this disease. Even patients with advanced keratoconus may be helped with this
technology. Numerous other conditions that cause the cornea to have an abnormal
surface configuration can also be treated with Custom Wave Contacts.
Since glasses often do not work in these situations, only a custom
contact can achieve an improvement in visual acuity.
The rings that are projected onto the cornea contain thousands of data
points. These rings are then converted into a
topographical map that undergoes further analysis. The
red area in this example is the abnormal steepening
associated with keratoconus, resulting in increased astigmatism and a
marked decrease in vision.
Presbyopia and Multifocal Contact Lenses
In the early to mid-forties, everyone develops a near focusing problem
called presbyopia (“old man-eye-ness” from the Greek
presbus+ops). If you are myopic or near-sighted, you
may be able to merely remove your glasses to read. However, for everyone else,
the use of reading or bifocal glasses is required.
Our vision demands have increased considerably because we now require a
variety of focusing points - distance, computer, reading and in actuality,
all points in between. Using the Wave Contact Lens System, it is
now possible to design multifocal contacts - contacts that provide the entire
range of vision.
The Wave contact lenses are designed by Dr. Rubman after the
corneal topography has been obtained. The parameters of the newly designed lens
are then sent over the internet directly to the custom lathe. Highly
oxygen-permeable material is used for multifocal contacts and corneas that have
very irregular contours. Soft lens material often can be used for distance
single vision correction.
Many previously unsuccessful contact lens wearers are now successful Wave
