Abstract
Purpose
:
case
report
of presbyopia correction in emmetropia by phakic IOL.
Case report:
A
fifty years old emmetropic man with uncorrected distance visual acuity
1,0
and
healthy eyes wants to avoid reading glasses.
We have considered two surgical options. First option was
refractive lensectomy with tri
focal IOL
implantation
and a the second rel
atively
new option was
phakic
diffractive intraocular lens. After the discussion with patient
,
we
decided
to implant
IPLC
(EyeolUK)
diffractive
presbyopic phakic
lens.
T
he preoperative
examinations were in favor of phakic IOL
implantation
,
only
ultra
sound
-
biomicroscopy
revealed narrower
angle
. YAG laser
peripheral iridotomy
was performed in both eyes
preoperatively
. Using a personal nomogram, an
IPCL
addition of 2
diopters (D) for the dominant eye and 3 D for his non
-
dominant eye was selected.
For implantin
g the IPCLs,
a technique without viscoelastic substance was used. After finishing the
surgery of the first eye, a high vault (985
μ
m) was detected. Because of that,
the size of the second
IPCL was
d
ecreas
ed by 0,5 mm
from 13
,
2 to 12
,
7 millimeters,
resulting in
a better vault value (568
μ
m
)
in
the second eye.
Seven months after surgery
the patien
t is happy,
reads without glasses
, both eyes are
quiet
,
without
cataracts,
with
normal intraocular pressure and corneas remain
clear
with
stable
endothelial
cell counts.
Patient
refers no dysphotopsias.
Conclusions:
Bilateral presbyopic phakic IOL implantation resulted in glass independence.
A careful
preoperative
anterior chamber assessment
is mandatory prior phakic IOL implantation
.
IPCL
presbyopic
diffractive lens is
a possible
option for correcting presbyopia in healthy eyes
of presbyopic
emmetropic patients.
Discussion:
It is important to bear in mind the potential risks of intraocular procedure. New bio
-
synthetic corneal inlay opens new possibili
ty for presbyopia correction in emmetropia or low hyperopia
without the risks of intraocular procedure
