Abstract

In order to study the influence of axial length in the increase of anterior chamber(AC) depth after phacoemulsification and the implantation of posterior chamber intraocular lens(PCL), we studied a group of 23 eyes a high myopia group with axial length over 27mm and another group of 23eyes a control group with axial length below 25mm. We measured the AC depth by using a Scheimflug camera preoperatively and at day 1, 3, 7, 30, and 60 after the operation. The mean axial length of the high myopia group was 29.70+/-1.51mm, and the axial length ranging from 27.31mm to 32.01mm. The preoperative mean anterior chamber depth of the high myopia group was 3.34+/-0.40mm and significantly deeper than that of the control group(2.94+/-0.39mm) (P=0.003). The percentage of the AC depth increase in the high myopia group was 26% at postoperative day 1, 28% at day 3, 29% at day 7, 32% at day 30, and 33% at day 60, while that in the control group was 19% at day 1, 15% at day 3, 22% at day 7, 21% at day 30, and 16% at day 60. In the high myopia group, the percentage of the AC depth increase after phacoemulsification and PCL implantation was higher than that in the control group. We observed continuous increase of the AC depth after the operation in the high myopia group. The axial length seems to be a factor in influencing the AC depth change after phacoemulsification, yet a further evaluation is needed to analyze the factors involved in the high myopic condition and to confirm the causes of the anterior chamber depth change in the high myopia group.
