Induced myopia associated with capsular bag distension syndrome.

Abstract

With reference to the article by Sorenson et al1Sorenson A.L. Holladay J.T. Kim T. et al.Ultrasonographic measurement of induced myopia associated with capsular bag distension syndrome.Ophthalmology. 2000; 107: 902-908Abstract Full Text Full Text PDF PubMed Scopus (34) Google Scholar on capsular bag distension syndrome, we have similarly noted a tight apposition of the intraocular lens (IOL) optic and posterior iris in eyes with capsular bag distension. This resulted in the deposition of iris pigments on the IOL in three of our eyes.2Theng J.T.S. Jap A. Chee S.P. Capsular block syndrome A case series.J Cataract Refract Surg. 2000; 26: 462-467Abstract Full Text Full Text PDF PubMed Scopus (58) Google Scholar All these eyes were seen on the first postoperative day, supporting our postulate that this group of eyes has a much more anterior displacement of the IOL compared with the subclinical group, which is seen later. This iris deposition did not seem to be a feature in the authors’ patients, however. Could it be because all our eyes were heavily pigmented Chinese eyes and theirs were lightly pigmented eyes? We have also experienced difficulties when using the Abraham lens in these cases, and our preferred technique is to perform the capsulotomy without a lens. We ask the patient to look to one side, and this allows us to focus the yttrium–aluminum–garnet beam onto the peripheral portion of the posterior capsule where it is less distended.
