Abstract

PURPOSE:

The purpose of this study was to examine the clarity of the visual axis after Nd:YAG laser capsulotomy following cataract extraction and primary intraocular lens implantation in a pediatric population.

METHODS:

A retrospective review was performed of all cases of cataract extraction and primary intraocular lens implantation over a period of 5 years. A group of children who had been treated by primary surgical posterior capsulotomy and anterior vitrectomy (Group 1) was used as the "gold standard," with whom the children treated with Nd:YAG laser capsulotomy (Group 2) were compared. The groups were studied for the incidence of opacification of the visual axis after the primary procedure.

RESULTS:

Data on 78 eyes were reviewed, and 56 eyes met inclusion criteria. Of these, 33 eyes were treated with primary posterior capsulotomy and anterior vitrectomy (Group 1) and 23 eyes were treated with Nd:YAG laser capsulotomy (Group 2). One eye (3%) of Group 1 experienced postoperative visual axis reopacification. Thirteen (57%) of 23 eyes in Group 2 experienced reopacification, requiring retreatment. Four eyes (17%) treated with Nd:YAG laser required a third treatment.

CONCLUSIONS:

In our series, 57% of patients treated with Nd:YAG laser capsulotomy experienced reopacification across the anterior hyaloid face. With the removal of the anterior vitreous at the time of cataract extraction, the scaffolding for cell migration is removed and reopacification of the visual axis is rarely seen. For patients in whom slit-lamp capsulotomy is not possible, especially if there is no Nd:YAG laser available for use in the operating room or when loss to follow-up may be an issue, primary posterior capsulotomy and anterior vitrectomy should be strongly considered.
