ZONES OF BEST VISION WITHOUT GLASSES
THERE ARE 3 ZONES OF VISION:
•
1) Far (TV, Driving)
•
2) Mid-Range (computer, desk-work),
3) Near (reading documents up-close)
STRENGTHS AND BENEFITS
OF THE LENS IMPLANT
ASTIGMATISM
CORRECTION
SURGERY or LENS
• CRYSTALENS AO
• TRULIGN TORIC
INTRAOCULAR LENS (IOL)
ASTIGMATISM CORRECTION WITH LENS
NEED FOR SPECTACLES AFTER SURGERY
BASIC
MONOFOCAL LENS
Most patients (90% or more)
will use glasses after surgery
for most activities (Eg.
•
Bifocals).
Does not correct astigmatism.
Far OR Near (not both).
Generally clearer long-distance
vision without glasses than a
basic lens due to reduction or
elimination of astigmatism.
Excellent vision far away
without glasses
•
•
•
No ability to refocus mid-range
(computer) or near (reading
printed documents).
Patients will definitely use
glasses to see computer and •
reading distances.
Excellent night vision,
far and computer
vision.
Very little night glare or
haloes.
Astigmatism corrected
with the Lensx laser
and/or Trulign lens.
Most patients will need
+1.50 over-the-counter
reading glasses to read
printed documents upclose.
Most patients will need
a “Yag capsulotomy
procedure” within one
year after implantation.

May need over-the-counter •
(+1.25) glasses to see the
computer or mid-range. Some
patients see a halo effect
around lights at night.
Reading in low light may
require glasses. Lens
reflection may be seen
cosmetically at times.
Moderate
No
Reading glasses may be
needed for mid-range

Excellent far and near
vision.
Ability to read small print
in all lighting
environments.
Astigmatism corrected
with the Lensx laser.
May need over-thecounter (+1.25) glasses to
see the computer or midrange. Some patients see
a halo effect around lights
at night.

LASER PREMIUM
CATARACT SURGERY
Yes
Laser guided corneal incisions and/or an
astigmatism-correcting lens implant
Yes. Some of the time. Far vision without
glasses will be clearer. Glasses to see
computer and to read printed
documents will be needed.
No blades. All laser.
No blades. All laser.
Excellent. More precise and exact when
laser controlled.
Laser energy is used to soften the
cataract first, then less ultrasound
energy is used to complete the cataract
removal process
None
Yes. Most of the time. Expect glasses to
see far and near. You will need bifocals
and/or reading glasses to refocus your
vision.
Blades, needles, or forceps
Blades, needles, or forceps
Good. Less precise when performed
manually
Patient benefits and surgical results
LASER ASTIGMATISMCORRECTING SURGERY
Yes
Laser guided corneal incisions
Minimal. An adjustable focus or
multifocal lens implant will reduce and
possibly eliminate your dependence on
glasses for seeing far, mid and near.
No blades. All laser.
