[Surgical treatment of congenital cataracts].

Due to the anatomical dimensions being smaller and the tissue structures being softer and more elastic in the young patient, surgery of paediatric cataracts represents a special challenge for the ophthalmic surgeon. Surgery is performed via a limbal or pars plana approach. The extreme high rate of secondary cataract formation in the paediatric or adolescent eye with closed posterior capsules is countered by means of complicated capsular surgery, special intraocular lens (IOL) implantation techniques, and vitreoretinal surgical procedures. It is customary not to implant IOLs before the children are 1-2 years old as increased axial length growth must be expected during the first 18 months after birth. IOL power is selected so that postoperative refraction is within the hyperopic range and with time, undercorrection will be balanced by bulbus growth. Preoperative and postoperative therapy is highly dependant on the extent of trauma sustained during surgery and should contain anti-inflammatory medication with and without steroids as well as antibiotics. Orthoptic follow-up examinations are also decisive for the long-term result.
