Pars plana lentectomy for treatment of congenital cataract.
BACKGROUND
Congenital cataract surgery can be performed using a pars plicata/plana or a limbal approach, if placement of an intraocular lens at the time of cataract removal is not a consideration. Because of the high incidence of secondary cataract formation in children the operation should be combined with capsulotomy and anterior vitrectomy.


METHODS
The series consisted of 30 eyes from 20 consecutive children who suffered from congenital cataract and underwent cataract surgery between May 1995 and June 2000. The inclusion criterion was congenital cataract affecting the visual axis. We performed the operations as lens aspiration with anterior and posterior capsulotomy and anterior vitrectomy via the pars plana or plicata. We used contact lenses to rehabilitate vision. All patients received intensive orthoptic and pleoptic treatment.


RESULTS
This surgical technique provided in all eyes a clear visual axis. During follow-up of 3 months to 4.5 years, secondary cataract developed in five eyes. Retinal detachment, glaucoma and endophthalmitis did not occur. One patient developed contact lens intolerance and a secondary intraocular lens was placed in the ciliary sulcus.


CONCLUSIONS
Lentectomy via a pars plana or pars plicata approach is a suitable and safe method for treating cataract in children. Our chosen method of lentectomy is an alternative to early implantation of an intraocular lens. It is possible to perform uncomplicated secondary implantation of an intraocular lens in the ciliary sulcus.
