| Summary: |
Purpose: The aim of the
study is to evaluate the dynamics of axial elongation of
pseudophakic eyes and changes in refraction pseudophakic
eyes in children after monocular or binocular cataract
surgery.
Material and methods: the observations of 79 children
(158 eyes) aged from 4 to 18 years (mean 9.7 ± 0.55)
after cataract surgery were conducted. The examined
group consisted of 105 pseudophakic eyes, the
comparative group consisted of 53 eyes without surgery
in the same observed group of children. Moreover, the
patients were evaluated in the following group: moncular
– binocular cataract, primary or secondary IOL
implantation, the age in groups were between 4-7 and
between 8-18 years.
Analysis statistically: STATGRAPHICS and SIMSTAT
programs, p (α) = 0.05.
Results: In the examined group (105 eyes) the mean
follow-up time was 4.2 years (± 0.3), the average age of
patients was 9.7 years (± 0.7). Improvement of visual
acuity was achieved mean 0.5 in 52.4% post operative
eyes observed, myopic shift was –0.7D (± 0.52). The
anatomic eyeball length increased up to 0.5mm (± 0.27).
The average age of patients of the control group was 9.7
years (± 0.83), follow-up 4.3 years (± 0.44), visual
acuity 0.8 (± 0.03). Mean elongation of the axial length
was 0.56 mm(± 0.26), mean refraction of the eyeball was
+0.38 D (± 0.54). The difference of the changes of
refraction between examined and control group was
statistically significant. The comparison of final
refraction in optical pathway (p=0.32) and the growth of
anatomic eyeball length (p=0.14), proved no significant
differences in the group with monocular and binocular
IOL. The comparative analysis of final refraction in
optical pathway (p1=0.36), and the growth of anatomic
eyeball length (p2=0.26) in the group with primary or
secondary IOL and in the younger or older children
(p1=0.52; p=0.98) in the both groups, did not
significantly differ.
Conclusions: The dynamics of axial elongation of
pseudophakic and phakic eyes in children is similar. The
myopic shift of pseufophakic eyes is bigger than in
phakic eyes. It should be undertaken in calculation of
the refractive power of intraocular lenses. |
