Contact Lens Advances and the Event of 2005
BY
JOSEPH T. BARR, OD, MS, FAAO, EDITOR
We learned in 2005 and believe we will see more
in 2006 how contact lenses have and will provide better vision while allowing better
comfort and in many cases better corneal and anterior segment health. Never before
have contact lens manufacturers delivered so many new, better, truly unique lenses
and lens care products in such a short period of time. This applies not only to
silicone hydrogels and specialty designs in modern hydrogel materials, but to GP
lenses as well. The United States has about 35 million lens wearers, who represent
about 20 percent to 35 percent of a typical eyecare practice and offer long-term
profitability. Following up from my May Editor's Perspective ("The Long-Term
Value of a Contact Lens Patient"), in the upcoming months we will feature research
from one of the top business schools in the world to help us understand the true
value of a contact lens patient.
Will
silicone hydrogel lenses replace hydrogel lenses in this decade? The trend is in
that direction, but we also learned in 2005 that some practitioners still use PMMA
lenses. Hydrogel lenses will be around for a long time. Should they be? That's another
question. There's great debate now about how much oxygen the cornea needs. Manufacturers
who sell lenses that provide more oxygen flow to the cornea argue that more oxygen
is better for the cornea. Manufacturers who sell more lenses that provide less oxygen
flux argue that you need less oxygen. More might seem better, but you need to consider
all of a patient's eye characteristics and needs including surface biocompatibility
and great vision. Keep in mind, too, that manufacturers create designs and gear
their marketing and sales programs around profitability, which depends on manufacturing
and delivery costs and pricing to all their channels for trade. These objectives
may not always be in line with yours. Our goal at Contact Lens Spectrum,
which in 2005 became part of Lippincott Williams & Wilkins VisionCare Group,
a Wolters Kluwer business, is to continue to provide you with everyone's point of
view.
I'm not complaining, but I will say that manufacturers try to
get me and our journal to go along with their point of view. I'll be the first to
admit that I'm human and have human biases, but I'm also one of the most objective
people you'll meet. One thing I won't compromise on is this: We'll continue to do
our best to deliver everyone's point of view in the contact lens field.
What's the 2005 Contact Lens Event of the Year? I'm going out
on a limb here and not choosing a lens modality. The event this year that I believe
will impact our field more than anything else is the removal of proposed legislation
that would force the FDA to approve products only when manufacturers agree to sell
to all channels of trade. We may see more FTC hearings to discuss how the Fairness
to Contact Lens Consumers Act is working and whether and this is the key
optometrists and ophthalmologists will have to stop selling contact
lenses, as is the case with drugs they prescribe or lab tests that they order. More
on this later this year.
