We measured the anterior chamber depth in 44 eyes that underwent posterior chamber intraocular lens (IOL) implantation surgery. An A-mode echography was used in the measurement. The IOL was of biconvex optics and C-looped haptics angled 5 derees anteriorly. The eyes were followed up until 10 months. Refractive state was measured by an autorefractometer at 1, 2 and 12 weeks after surgery. The anterior chamber depth averaged 3.30±0.55mm before surgery. It averaged and 3.33±0.37mm at 2 days, 3.53±0.37mm at 1 week, 3.25±0.43mm at 2 weeks and 3.57±0.41 at 12 weeks after surgery. It remained stabilized thereafter. There was no difference in the value before and 2 days after surgery. The value at 1 week was significantly greater than the preoperative value (p<0.01). The value increased during 2 days to 1 week after surgery in 71% of eyes. It became shallower again to reach the preoperative value. The refractive state tended toward myopia along with decrease in chamber depth at 2 weeks after surgery. The refractive state became the same between 1 week and 3 months after surgery.
