Anatomic evaluation of the Morcher capsular tension ring by ultrasound biomicroscopy

J Cataract Refract Surg. 2006 May;32(5):846-8. doi: 10.1016/j.jcrs.2006.02.009.


Purpose: To analyze the anatomic position of the Morcher capsular tension ring (CTR) by anterior segment ultrasound biomicroscopy.

Setting: Academic institution.

Methods: Fourteen pseudophakic eyes (13 patients) with placement of a Morcher CTR during cataract extraction had ultrasound biomicroscopy.

Results: In all eyes, the CTR had a position between the intraocular lens haptics and the ciliary body without posterior iris touch.

Conclusions: In this small population of eyes, the Morcher CTR was found to be in a consistent, safe, and stable location in the capsular bag.
