Aim: To examine the difference between the anterior segment biometric
parameters preoperatively and the lens hurdling after implantable Collamer lens
(ICL) implantation.
Subjects and methods: A comparative study was done on of 30 patients (60
eyes) who underwent surgery of implantable collamer lens (ICL) implantation in
a in private center all over the last fourteen months, where these parameters
involve error of refraction, central corneal pachymetry, corneal white to- white
diameter, and anterior chamber depth, were stately correlated to sizing of lens
to hurdling the central lens as assessed by anterior segment OCT postoperatively.
correlations by Pearson correlation was used to identify statistical
significance. by using (ANOVA) test was done to detect parameters correlation
and ICL hurdlinging a further analysis by subgrouping them according to ICL
sizing.
Result: after surgery, ICL lens hurdling was 495.95±244.182 μm (40- 1070).
This was positively correlated to anterior chamber depth and pachymetry.
Subgroup analysis showed that in group 2, statistically negative correlations of
ICL hurdlinging with white to white (R=-0.461, p=.009),positive correlation to
anterior chamber depth (R=0.491, p=.005) and pachymetry (R=0.558, p=.001)
were shown. Group 3 demonstrated lens hurdlinging negatively correlated to
preoperative spherical equivalent (R=-0.428, p=0.226), positively correlated to
pachymetry (R=0.504, p=.007), negatively correlated to ICL spherical
equivalent (R=-0.472, p=.013).
Conclusion: white to white, anterior chamber depth, pachymertry and spherical
equivalent exhibited a significant correlation with ICL hurdlinging and they
were the main determinant parameters for postoperative ICL hurdling.
