目的：应用傅里叶域光学相干断层扫描（OCT）测量白内障激光视力矫正术后角膜度数并计算人工晶状体（IOL）度数。Doheny眼科研究所，洛杉矶，加利福尼亚，和Cullen眼科研究所，休斯顿，德克萨斯州，美国。前瞻性比较病例系列。本研究纳入了既往近视激光视力矫正并行单焦点人工晶体植入术的患者。傅里叶域OCT系统用于测量角膜功率和视厚测量。采用部分相干生物测量法测量轴长和前房深度。建立了基于oct的人工晶状体配方，并将术后屈光平均绝对误差（MAE）与Haigis-L配方进行比较。在Doheny，还使用临床病史法、隐形眼镜过折射法和裂隙扫描断层扫描总光功率测量角膜功率。16名患者的16只眼睛在两个地点进行了登记。以前的激光视力矫正范围为- 9.81到- 0.88屈光度(D)。基于oct的人工晶状体计算MAE为0.50 D， Haigis-L公式计算MAE为0.76 D （P = 0.14）。在Doheny入组的6只眼中，oct法计算人工晶状体的MAE为0.60 D，而隐形眼镜过屈光法（MAE = 1.46 D, P < 0.05）和临床病史法（MAE = 1.78 D, P < 0.05）较差。裂隙扫描层析显示MAE为1.28 D （P < 0.05）。在激光后视力矫正眼中，基于oct的人工晶状体度数计算的预测精度等于或优于现行标准。
To use Fourier-domain optical coherence tomography (OCT) to measure corneal power and calculate intraocular lens (IOL) power in cataract surgeries after laser vision correction. Doheny Eye Institute, Los Angeles, California, and Cullen Eye Institute, Houston, Texas, USA. Prospective comparative case series. Patients with previous myopic laser vision correction who had monofocal IOL implantation were enrolled. A Fourier-domain OCT system was used to measure corneal power and pachymetry. Axial length and anterior chamber depth were measured with partial coherence biometry. An OCT-based IOL formula was developed, and the mean absolution error (MAE) of postoperative refraction was compared with that for the Haigis-L formula. At Doheny, corneal power was also measured using the clinical history method, the contact lens overrefraction method, and slit-scanning tomography total optical power. Sixteen eyes of 16 patients were enrolled at the 2 sites. Previous laser vision correction ranged from −9.81 to −0.88 diopter (D). The MAE was 0.50 D for OCT-based IOL calculation and 0.76 D for the Haigis-L formula (P = .14). In the 6 eyes enrolled at Doheny, the MAE of OCT-based IOL calculation was 0.60 D. In comparison, the contact lens overrefraction (MAE = 1.46 D, P < .05) and clinical history (MAE = 1.78 D, P < .05) methods were worse. Slit-scanning tomography gave an MAE of 1.28 D (P > .05). The predictive accuracy of OCT-based IOL power calculation was equal to or better than current standards in post-laser vision correction eyes.
