[The postoperative change of depth of anterior chamber, refraction and anterior capsulorhexis size after intraocular lens implantation].

We evaluated postoperative shrinkage of anterior capsule, depth of anterior chamber, and refraction in 161 eyes, on which we performed continuous curvilinear capsulorhexis and phacoemulsification, and then implanted an intraocular lens in the capsular bag. We measured the depth of anterior chamber, anterior capsulorhexis size, contact surface with intraocular lens, and quantity and rate of anterior capsular shrinkage on the basis of anterior segment photographs before the operation, and 1 week, 1 month, and 3 months after the operation. After operation the depth of the anterior chamber deepened gradually, anterior capsulorhexis size narrowed, and refraction tended to hyperopia. There was a correlation in anterior chamber depth and anterior capsulorhexis size between preoperative and postoperative values but no correlation in refraction. The depth of the anterior chamber was dependent on the degree of anterior capsular shrinkage. There was a correlation between the depth of anterior chamber and the degree of anterior capsular shrinkage.
