[Surgical correction of congenital lens ectopia : anterior approach Klötis phacophagia employing apparatus (author's transl)].

The anterior transcorneal approach, using Klötis apparatus, was employed to conduct phacophagia in 29 eyes. This transcorneal approach to an ectopic lens is sufficient if care is taken to place the keratotomy on the meridian opposite to that of the lens displacement. Patients have been followed up for from 1 to 5 years and anatomical results are excellent; no complications have been reported, but this technique cannot be employed in patients over 30 years of age. Indications and contraindications for this method are discussed, together with the advantages and inconveniences of other techniques: discussion-aspiration and phacophagia through the pars plana.
