Presented in part at the 2nd American-International Congress on Cataract, IOL and Refractive Surgery, Washington D. C., April 1989. Journal of Cataract & Refractive Surgery: March 1991 - Volume 17 - Issue 2 - p 205-210 doi: 10.1016/S0886-3350(13)80251-9 Buy Metrics Abstract Optimal fixation and position of an intraocular lens (IOL) is achieved when it is located in the capsular bag. A peripheral tear from the central opening to the lens periphery is associated with a high incidence of dislocation of at least one loop from within the capsular bag and lens decentration. A central round continuous capsulectomy (capsulorhexis), within the zonule-free area, provides long-term and balanced IOL fixation. To perform a well-controlled capsulectomy, a deep and stable anterior chamber should be maintained throughout the surgery. This is achieved by using a continuous anterior chamber maintainer that regulates the pressure in the anterior chamber. This paper reviews the clinical anatomical guidelines of the lens capsule and the anterior chamber and presents the authors' preferred technique for optimal anterior capsulectomy. © Williams & Wilkins 1991.
