Delayed Dislocation of iol: Occult Intraocular Foreign Body or Trauma can be the Reason

Abstract

Delayed dislocation of an IOL is a complication which cannot be prevented or predicted but may cause
profound visual loss in a good pseudophakic eye.
AIM:
To analyse risk factors associated with all the cases
of delayed dislocation of IOLs
.
METHODS
:
Hospital based prospective intervention study during
2003
-
2018
.All cases of dislocated
IOLs were included.
Cases with history of surgical complications were exclude
d.
Routine
investigations with MRI were
done.
Multi
variate analysis to detect risk factors was done
.
RESULTS
:
Out of 25 cases
3 cases with h/o PCR were excluded.
Mean age:63.2 years,
male: female
ratio :5:1.Mean interval:6.5 years.12 cases of Iris claw lens dislocated in AC,3 cases of PCIOL with IOFB
detected on MRI,5 cases of trauma with perfect capsulorrhexis, 2 cases of pseudo
exfoliation ,2 cases
had longer axial length(>26mm).Multivariate ana
lysis confirmed occult IOFB and trauma as risk factor.
CONCLUSION:
Occult IOFB and trauma can lea
d to delayed dislocation of IOL
.
