Changes in the area of the anterior capsule opening after intraocular lens implantation.
OBJECTIVE
To evaluate the reduction rate of the area of the anterior capsule opening after continuous curvilinear capsulorhexis (CCC) with 3 types of intraocular lenses (IOLs).


METHODS
St. Mary's Hospital, The Catholic University of Korea, Seoul, Korea.


METHODS
Sixty-five eyes of 51 patients having phacoemulsification and IOL implantation were assigned to 1 of 3 groups based on type of IOL: 1-piece acrylic (n = 16), 3-piece acrylic (n = 26), or silicone (n = 23). The area of the anterior capsule opening was measured 1 day and 1, 2, 3, 6, and 12 months postoperatively.


RESULTS
There was significant reduction in the area of the anterior capsule opening 1 day to 3 months postoperatively in all 3 groups (P <.001). There was no further reduction after 3 months in any group. The reduction in the area of the anterior capsule opening was significantly less in both acrylic IOL groups than in the silicone IOL group at 3 months (P =.040) and 12 months (P =.023); however, there was no significant difference between the 2 types of acrylic IOLs (P =.933).


CONCLUSIONS
Although there was a reduction in the area of the anterior capsule opening in all patients, the amount was significantly less in the 2 acrylic IOL groups than in the silicone IOL group. This should be considered when selecting an IOL, especially for eyes at risk for capsule contraction.
