Comparison of epilenticular IOL implantation vs technique of anterior and primary posterior capsulorhexis with anterior vitrectomy in paediatric cataract surgery.
OBJECTIVE
To compare the functional outcome of epilenticular intraocular lens (IOL) implantation vs the technique of anterior continuous curvilinear capsulorhexis (ACCC), posterior continuous curvilinear capsulorhexis (PCCC) with vitrectomy and in-the-bag IOL implantation in paediatric cataract surgery.


METHODS
Forty eyes of 33 children with developmental or traumatic cataract, whose mean age was 2-12 years, were randomly divided into two groups A and B. Group A patients underwent epilenticular IOL implantation while in group B patients, ACCC, PCCC with anterior vitrectomy with in-the-bag IOL implantation was performed. Equal number of eyes (10 each) with developmental cataracts (subgroups A1 and B1) and traumatic cataracts (subgroups A2 and B2) were allotted to both the groups. Postoperative visual acuity, opacification of the visual axis, and possible complications were observed and analysed.


RESULTS
Four eyes in subgroup B2 had fibrous or ruptured capsules, and were managed by epilenticular IOL implantation technique. One eye in subgroup B2 developed central posterior capsular opacification and hence required a secondary capsulotomy. All cases in group A maintained a clear visual axis at the last follow-up. Minimal postoperative inflammation was noticed in all groups, which subsided with anti-inflammatory medication. At the last follow-up, all eyes in group A gained visual acuity >/=6/18. Whereas in group B, visual acuity >/=6/18 was obtained in 85.7% cases with the epilenticular IOL implantation technique and in 83.3% cases with ACCC and PCCC with anterior vitrectomy technique.


CONCLUSIONS
Epilenticular IOL implantation offers a safe and effective alternative for management of paediatric cataract. In selected cases of traumatic cataract, it is the preferred treatment modality.
