方法：对22例(平均年龄：59.05±8.70岁)并发白内障和翼状胬肉(长度2-5mm)患者进行前瞻性单中心研究，随访时间为3mo～1a。测定术前和术后3mo的平均角膜曲率(K_mean)、平均散光和最佳矫正视力(LogMAR)。观察术前角膜曲率和翼状胬肉大小与预测误差的关系。

结果：共18例(81.8%)患者PE<±0.50D，4例(18.2%)患者PE为±0.50D～±1.00D，没有PE>1.00D的患者。手术前后眼轴长度无差异(P=0.77)。K_mean从术前42.994±1.536增加到术后43.324±1.479(P=0.105)。术后角膜散光由术前2.09±0.789D降至术后0.523±0.277D(P<0.05)。BCVA(LogMAR)从术前1.007±0.402显著提高到术后0.024±0.062(P<0.05)。角膜曲率变化与预测误差无相关性(r=-0.29，P=0.19)。翼状胬肉大小与预测误差无相关性(r=0.2997，P=0.17)。

结论：超声乳化与折叠式人工晶状体植入联合自体结膜移植术的应用是一种安全有效的手术方法。

METHODS:A prospective single centered study was performed on 22 patients(mean age: 59.05±8.70 years)of concurrent cataract and pterygium(size 2-5 mm in length), who attended the outpatient department during the study period of one year, and the minimum follow up was 3mo-1a for all patients. Mean keratometry(K_mean), mean astigmatism, best corrected visual acuity(LogMAR), preoperatively and 3mo postoperatively had been determined. The corneal curvature, pterygium size and the prediction error(PE)were observed.

RESULTS: The amount of PE was <±0.50 D in 18 patients(81.8%)and ±0.50 D to ±1.00 D in 4 patients(18.2%). None of the patients had PE of >1.00 D. The mean axial length did not change significantly(P=0.77)postoperatively. The mean keratometric reading increased from 42.994±1.536 preoperatively to 43.324±1.479 postoperatively but this was not significant(P=0.105). The corneal astigmatism decreased significantly from 2.09±0.789 D preoperatively to 0.523±0.277 D postoperatively(P<0.05). BCVA(LogMAR)significantly improved from 1.007±0.402 preoperatively to 0.024±0.062 postoperatively(P<0.05). No correlation was found between changes in keratometry and PE(r=-0.29, P=0.19). And, there was no correlation was found between pterygium size and PE(r=0.2997, P=0.17).

CONCLUSION: Combined phacoemulsification+foldable intraocular lens(IOL)implantation and conjuctival autograft(CAG)application was safe and effective procedure.
