Objective To compare the amounts of intraocular lens (IOL) decentration and tilt, the anterior chamber depth (ACD) and the degree of posterior capsule opacification (PCO) using the Pentacam Scheimpflug System after cataract surgery between eyes with 1-piece acrylic IOL and 3-piece acrylic IOL Methods It was a perspective study. Fifty-one patients with bilateral senile cataract had implantation of a 1-piece SA60AT IOL in one eye and a 3-piece MA60BM IOL in the contralateral eye. The amount of IOL decentration, tilt, the ACD, and the degree of PCO was measured using the Pentacam Scheimpflug System 1 day and 1,6, 12 and 24 months postoperatively. Results There were no significant changes during the 24 m follow-up period in the decentration ( 0. 37 ± 0. 16, 0. 36 ± 0. 15, 0. 36 ± 0. 16, 0. 37 ± 0. 15,0. 38 ± 0. 16), tilt (3.59±0.91,3.64 ±0.92,3.61 ±0.90,3.63 ±0.90,3.70 ±0. 89)or PCO(22. 20 ±3.99,21.96 ±4. 00,22.40 ± 4. 03,22. 53 ± 4. 00,22. 95 ± 3. 87 ) in the 1 -piece SA60AT group ( F = 1. 938,0. 785,1. 814;P ＞ 0. 05 ) or in the 3-piece MA60BM group (0. 34 ± 0. 14,0. 33 ± 0. 14,0. 34 ± 0. 14,0.35±0.14,0.36 ±0.14),(3.55 ±0.90,3.57 ±0.92,3.63 ±0.88,3.61 ±0.88,3.65 ±0.89),(21.14 ±3.88,20. 98 ±3. 87,21.23 ±3. 83,21.59 ±3. 82,21.65 ±3. 87) (F = 1. 004,0. 525,1. 963;P ＞0. 05). There was no significant difference between the two groups in IOL decentration (t = 0. 802,0. 701,0.588,0. 898,0.631), tilt (t =0. 199,0.337,0.094,0. 121,0.248) or PCO(t = 1.214,1. 119,1.334,1. 082,1. 517)at any time points (P ＞ 0. 05 ). The ACD did not change after the surgery in the 1-piece group (3.90 ±0. 99,3.88 ± 1.07,3.91 ± 1.01,3.90 ± 1.02,3.92 ± 1.02) (F= 1. 333,P ＞0. 05) but was significantly deeper in the 3-piece group ( 4. 37 ± 1.02,3.90 ± 0. 98,3.95 ± 0. 99,3.93 ± 0. 96,3.97 ± 0. 99 ) ( F = 92. 757, P ＜ 0. 05 ) one day after the operation. The ACD was more shallow in the 1-piece SA60AT group than in the 3-piece MA60BM group at all time points. However, the difference was statistically significant only at 1 day after surgery ( t = 102. 944, P ＜ 0. 05 ). Conclusions The degrees of IOL decentration, tilt, ACD and PCO in eyes with a 1-piece acrylic IOL with flexible haptics implanted in the capsular bag were similar to those in eyes with a 3-piece acrylic IOL with rigid PMMA haptics. But the 1 -piece acrylic IOL provides a better stability than the 3-piece acrylic IOL in the early stage postoperatively.
