目的：评估 Tetraflex 可调节人工晶状体 (AIOL) 的眼前段生物测量以及向前运动对调节幅度 (AMP) 的贡献。方法：接受超声乳化术并植入 Tetraflex AIOL 和对照非调节性人工晶状体的患者在放松和最大调节状态下通过定制的长扫描深度谱域光学相干断层扫描进行成像。进行眼前段生物测定并与临床表现（包括 AMP）相关联。结果：与对照组相比，Tetraflex 组患者的远校正近视力更好（logMAR 0.43±0.10 vs. logMAR 0.51±0.10，P<0.05），AMP 更高（1.99±0.58 屈光度 [D] vs. 1.59±0.45 D，P<0.05）。调节期间术后前房深度 (ACD) 的测量显示 16 只眼 (69.6%) 的 AIOL 向前移动。与对照组相比，Tetraflex 组中出现向前运动的病例比例更高（≥2 检验，P<0.001）。 AIOL组AMP与术后调节期间ACD变化呈负相关（r=-0.47，P<0.05），而对照组AMP与术后瞳孔直径呈负相关（r=-0.57，P<0.05）。结论：Tetraflex AIOL 似乎有向前移动的趋势；然而，Tetraflex AIOL 在自然调节过程中的轻微向前轴向移动可能不会产生临床相关的光功率变化。
Objectives: To evaluate the anterior segment biometry of the Tetraflex accommodating intraocular lens (AIOL) and the contribution of forward movement to the amplitude of accommodation (AMP). Methods: Patients who underwent phacoemulsification with implantation of Tetraflex AIOLs and control nonaccommodating intraocular lenses were imaged by custom-built, long scan depth spectral-domain optical coherence tomography at relaxed and maximal accommodative states. Anterior segment biometry was performed and correlated with the clinical manifestation including AMP. Results: Patients in the Tetraflex group showed better distance-corrected near visual acuity (logMAR 0.43±0.10 vs. logMAR 0.51±0.10, P<0.05) and greater AMP (1.99±0.58 diopters [D] vs. 1.59±0.45 D, P<0.05) compared with the control group. The measurement of the postoperative anterior chamber depth (ACD) during accommodation showed a forward movement of the AIOLs in 16 eyes (69.6%). Compared with the control group, a greater proportion of cases in the Tetraflex group experienced forward movement (&khgr;2 test, P<0.001). The AMP in the AIOL group negatively correlated with changes in postoperative ACD during accommodation (r=−0.47, P<0.05), whereas AMP in the control group negatively correlated with postoperative pupil diameter (r=−0.57, P<0.05). Conclusions: The Tetraflex AIOLs seemed to have a tendency for forward movement; however, the slight forward axial shifts of the Tetraflex AIOL during natural accommodation may not produce a clinically relevant change in optical power.
