Abstract Details

Purpose:

To compare surgical outcome of posterior optic capture of Intraocular Lens (IOL) without anterior vitrectomy and endocapsular IOL implantation with anterior vitrectomy in children undergoing cataract surgery.

Setting:

Advanced Eye Centre, Post Graduate Institute of Medical Education and Research. Chandigarh, India

Methods:

In this prospective randomised interventional study consecutive children with bilateral congenital/developmental cataract who were operated over a period of 1 year were included. One eye of all patients underwent IOL implantation with optic capture through a primary posterior continuous curvilinear capsulorhexis (PPC) without vitrectomy(group 1) while in the other eye of the same child IOL was implanted in the bag after a PPC and anterior vitrectomy(group 2). Intraoperative challenges and postoperative complications till a follow up of 2 years were noted.

Results:

26 eyes of 13 children out of 16 patients were included for analysis with 13 eyes in each group. Mean age at surgery was 21 ± 14.7 months with most being infants (7/13). At a mean follow up of 25.69 ± 1.06 months all eyes in both groups maintained a clinically centred IOL with no significant visual axis obscuration (VAO). However in 8/13 eyes in group 2 there was increasing proliferation of lens epithelial cells though visually insignificant. Fibrinous complications were more in group 2 (6/ 13) vs group 1 (1/13); p=0.039.Glaucoma was not observed in any eye.

Conclusions:

Posterior optic capture is a safer alternative to conventional pediatric cataract surgery in terms of inflammatory sequelae and lens epithelial cell proliferation. It may also decrease the incidence of glaucoma as the vitreous is untouched. However the two methods work equally well in preventing visual axis obscuration over a long follow-up.
