Pars plana lentectomy for treatment of pediatric cataract
P. Meier, I. Sterker, P. Wiedemann
Congenital cataract surgery can be performed by using a limbal approach or a pars plana (plicata) approach. The purpose of the study is to evaluate the outcome in eyes of children who underwent pars plana (plicata) lentectomy.
Method: Cataract surgery through a pars plicata or pars plana incision was performed in 33 eyes and was combined in 27 eyes with an anterior and posterior capsulectomy and anterior vitrectomy. 6 eyes in 3 patients had subluxatio lentis.
We used contact lenses for optical rehabilitation. All patients got an intensive orthoptic and pleoptic treatment.
Results: This surgical technique provides in all eyes a clear visual axis. During the follow-up period between one month and 4,5 years, secondary cataract developed in 3 eyes. Retinal detachment, glaucoma or endophthalmitis was not observed. One patient developed a contact lens- intolerance and a secondary intraocular lens was placed in the ciliary sulcus.
Discussion: The pars plana or plicata lentectomy in combination with a capsulectomy and anterior vitrectomy provides, in most cases, a long-term clear visual axis. This technique allowed the secondary implantation of an intraocular lens on the rim of residual lens capsule.
The functional outcome depends on postoperative orthoptic and pleoptic management of the children.
