| Summary: |
Purpose: To
evaluate the outcome and safety of foldable 1-piece
acrylic hydrophobic IOL implantation in children.
Material and Methods: The results of cataract
extraction and acrylic IOL implantation in children were
retrospectively analyzed in 38 eyes of 28 children in
age between 3 and 12 years. In all eyes primary
posterior capsulotomy and anterior vitrectomy were
performed. Thirty IOLs were implanted in the capsular
bag, six IOLs were sulcus-fixated. All patients were
examined on the first postoperative day, at 4-th and
8-th week and then every 6 months. The particular
observations included the incidence of capsular bag
fibrosis, cell deposits, haptic compression, corneal
thickness and corneal endothelial density. Number of
cell deposits were graded in three groups: 0 – fewer
than 5 deposits, 1 – below than 10, 2 – more than 10 on
the IOL surface.
Results: Single piece acrylic IOLs were
successfully implanted in 38 eyes. Incidence of
transient postoperative inflammation was observed in 10
eyes. In 2 eyes postoperative inflammation was fairly
high with fibrinous reaction. In all patients there were
no postoperative opacification of the visual axis.
Pigment or cell deposits were seen on the IOL surface in
0 group – 28 eyes, in 1 group – 8 eyes, in 2 group – 2
eyes. Central corneal thickness increased after surgery
in 30 eyes (74%). There were no changes in endothelial
cells counts and morphologic features in operated eyes.
All IOLs remained anatomically stable and well centered
during the mean follow-up of 18 months (range 6 to 27).
Conclusions: Our results suggest that acrylic
one-piece IOL implantation in children is a safe
procedure with good and stable short-term anatomic
results. This IOL appears clinically to be biocompatible
when placed in the eyes of children despite the
increased tissue reactivity known to occur in young
patients. Longer follow-up is necessary to answer the
questions about the long term safety of acrylic lens
implantation in a child’s eye. |
