Abstract Details

Purpose:

As paediatric capsule is more elastic and requires more force for tearing, it’s difficult to manage in cases of opacified /calcified capsule. The study is done to evaluate the efficacy of vitrectorhexis as a procedure for anterior and posterior capsulotomy in cases of thick calcified capsule.

Setting:

Advanced phacomachines with vitrectomy is used. Center for Sight Group of Hospitals, India

Methods:

This is a prospective clinical study in which 20 pediatrics eyes are done. In all cases either the anterior or the posterior capsule is thickened or there is discontinuity in the capsule .The cases are traumatic cataracts mainly along with absorbed developmental cataracts. In all cases the incision was corneal and the capsule was stained with 0.1% of trypan blue dye. High molecular weight OVD is used. With the cutting port facing posteriorly towards the capsule the capsule was engaged and then the capsular opening was enlarged to optimal size. The foldable IOL implanted in bag.

Results:

The vitrectorhexis is done for the posterior capsule in 14 eyes, in 5 eyes for anterior capsule and in one eye for both anterior and posterior capsule. In 2 cases preexisting capsular tear was present due to trauma so vitrectorhexis is just used to make a round opening. In 16 cases the vitrectorhexis resisted radial tear and the IOL was put safely in the bag. In four cases IOL was implanted in the sulcus due to preexisting capsular tear or due to fused capsule.

Conclusions:

Manual CCC remains the gold standard for pediatrics cataracts. Vitrectorhexis is more utilized technique in children less than 2 year of age .It is safer and easier method of capsulorhexis in thick/calcified capsule. No radial tear is reported with this technique.
