Clinical Study on Extracapsular Lens Extraction in Cataract Surgery

ABSTRACT

An extracapsular lens extra.ction usually provides an excellent functional result and leaves an eye whose anatomic integrity in some ways exceeds that seen after an intracapsular lens extraction. This technique has the advantage of a smaller incision and a shorter convalescence. In the prevention of certain complications such as operative vitreous loss and postoperative cystoid macular edema, well planned extracapsular lens extraction before surgery is followed by far fewer complications than the misfortune of a ruptured capsule of an immature cataract. Cataract extraction was performed as usual conventional method. Intracapsular lens extraction was performed in 21 eyes and extracapsular lens extraction in 15 eyes. Although the incidence of iris adhesion to the cornea or vitreous, iris peaking, vitreous adhesion to the posterior corneal wound and operative rupture of the anterior hyaloid membrane were higher than those of the intracapsular lens extraction, sorious complications were not resulted. Fundus fluorescein angiograms were taken in all patients within 6 months postoperatively. The incidence of cystoid macular edema in the extracapsular lens extraction (33%) was lower than that of the intracapsular lens extraction(43%).
