Op. Dr. Lütfi Seyrek, an Ophthalmologist, stated that multifocal
intraocular lenses have now replaced single-focus intraocular lenses, and as a
result, there is no longer a need for distance or near glasses.
Dr. Lütfi Seyrek from Medicana Healthcare Group stated that
single-focus intraocular lenses were used in the past for the treatment of
cataract patients, and these patients had to use distance or near glasses after
the surgery. However, nowadays, multifocal intraocular lenses are used, which
eliminates the need for glasses. Dr. Seyrek explained that the new generation
of intraocular lenses, such as multifocal (multiple focus), trifocal (three
focus), or edof (enhanced depth of focus) lenses, are commonly referred to as
"smart lenses" because of their special design that enables patients
to read distant, intermediate, and near objects comfortably without glasses
after the surgery. This technology is currently the most advanced lens
technology available and can significantly improve the quality of life for
cataract patients.
Dr. Lütfi Seyrek emphasized that the most important
application area for smart lenses is cataract disease. He explained that during
cataract surgery, the natural lens of the eye, which has lost its transparency,
is removed and replaced with a lens that can remain in the eye for a lifetime.
Additionally, smart lenses can be used in cases where the functional capacity
of the lens inside the eye is compromised even before the formation of cataracts.
This technique is particularly effective for patients over 40 years of age who
have distance refractive errors such as myopia, astigmatism, and hyperopia,
which can lead to near-vision problems. The surgery enables patients to get rid
of distance and near glasses for a lifetime. The rings or enhanced depth of
focus on smart lenses bend the light that enters the eye from distant,
intermediate, and close distances and focus it onto a single focal point on the
retina. This enables the lens to focus simultaneously on objects at near,
intermediate, and far distances with a single lens.
According to Lütfi Seyrek, the main reason for changes in
vision after the age of 40 is related to the eye's natural lens. He explains
that with the surgery, the natural lens that causes the change vision is
removed and an artificial lens is implanted, so no changes in vision are
expected after the surgery. The smart lens surgery is performed with the eye
being numbed with drops, and the procedure usually takes around 10-15 minutes
for one eye. The surgery for both eyes is typically done at a one-day interval.
After the procedure, if you feel well, there is no need to stay in the hospital
and you can be discharged immediately. Within one day after the operation, your
vision will significantly improve, and you can return to your work.
