Long-term efficacy and complications of black diaphragm intraocular lens implantation in patients with traumatic aniridia.
[aniridia]
To
determine
the
efficacy
and
complications
of
long
-term
black
diaphragm
intraocular
(
BDI
)
lens
implantation
in
patients
with
traumatic
aniridia
.
This
study
analysed
the
demographics
,
clinical
evaluations
and
treatments
of
95
patients
with
BDI
lens
implantation
and
75
patients
who
wore
rigid
gas-permeable
(
RGP
)
contact
lenses
(
CLs
)
.
The
clinical
examinations
included
evaluations
of
visual
acuity
(
VA
)
,
best-corrected
visual
acuity
(
BCVA
)
,
intraocular
pressure
measurements
(
IOP
)
,
and
corneal
endothelial
cell
density
(
ECD
)
.
Ultrasound
biomicroscopy
(
UBM
)
was
used
to
observe
the
haptic
lens
positions
.
In
the
BDI
group
,
light
sensitivity
dramatically
decreased
postoperatively
in
all
patients
,
and
78
patients
(
82
.
1
%
)
had
a
BCVA
score
>
20
/
200
.
A
total
of
36
eyes
(
37
.
89
%
)
developed
elevated
IOP
after
the
BDI
lens
implantation
,
and
12
eyes
(
12
.
63
%
)
underwent
glaucoma
laser
surgery
.
Corneal
decompensation
occurred
in
nine
eyes
(
9
.
47
%
)
,
three
of
which
developed
glaucoma
.
Twelve
patients
(
12
.
63
%
)
experienced
limbal
stem
cell
failure
,
and
16
patients
(
16
.
84
%
)
had
eccentric
BDI
lenses
.
All
patients
in
the
RGP
group
had
a
BCVA
score
≥
20
/
200
.
Only
seven
eyes
(
9
.
3
%
)
had
cornea
complications
.
There
were
no
statistically
significant
differences
in
either
the
IOP
or
ECD
after
wearing
the
RGP
CLs
.
G
laucoma
,
corneal
decompensation
,
limbal
stem
cell
failure
,
and
eccentric
BDI
lenses
appeared
to
be
the
major
long
-term
complications
in
BDI
lens
implantation
.
BDI
lens
implantation
could
effectively
improve
postoperative
outcomes
by
reducing
glare
disability
,
improving
visual
performance
,
and
addressing
cosmetic
issues
.
Because
the
implantation
of
the
BDI
lens
in
traumatic
aniridia
had
a
high
incidence
of
complications
,
this
treatment
should
be
used
with
caution
,
and
the
long
-term
complications
should
be
seriously
considered
.
