【摘要】：目的評(píng)價(jià)Pentacam法測(cè)量近視激光術(shù)后角膜屈光力的準(zhǔn)確性。方法將白內(nèi)障手術(shù)患者15例(19眼)于術(shù)后用Pentacam法測(cè)量角膜等效屈光力(EKR),用臨床病史法及非接觸式光學(xué)相干生物測(cè)量?jī)x(IOL-Master)方法測(cè)量角膜屈光力。比較3種方法術(shù)后角膜屈光力的中值絕對(duì)誤差(Med AE)、平均絕對(duì)誤差(MAE),以及3種方法術(shù)后的屈光誤差。結(jié)果 Pentacam法中角膜屈光力的Med AE、MAE均明顯低于臨床病史法、IOL-Master法(P0.05),Pentacam法的角膜屈光力明顯低于IOL-Maste法(P0.05)。在±0.25 D、±0.50 D、±1.00 D范圍內(nèi),Pentacam法的眼數(shù)均明顯高于IOL-Master法(P0.05)。結(jié)論 Pentacam法能準(zhǔn)確測(cè)算近視激光術(shù)后人工晶狀體度數(shù),在術(shù)前相關(guān)資料缺失時(shí),Pentacam法可以替代臨床病史法計(jì)算準(zhǔn)分子角膜屈光術(shù)后角膜屈光力。
[Abstract]:Objective to evaluate the accuracy of Pentacam method in measuring corneal refractive power after laser myopia. Methods the corneal equivalent refractive power (EKR) was measured by Pentacam method in 15 patients (19 eyes) after cataract surgery, and corneal refraction was measured by clinical history method and non-contact optical coherence biometer (IOL-Master). The mean absolute error (Med AE), mean absolute error (mae) of corneal refractive power and refractive error of three methods were compared. Results the corneal refractive power of Pentacam was significantly lower than that of IOL-Master (P0.05) and Pentacam (P0.05). The corneal refractive power of Pentacam was significantly lower than that of IOL-Maste (P0.05). In the range of 鹵0.25 D, 鹵0.50 D, 鹵1.00 D, the number of eyes of Pentacam method was significantly higher than that of IOL-Master method (P0.05). Conclusion Pentacam method can accurately calculate the degree of intraocular lens after laser myopia. Pentacam method can replace the clinical history method in calculating corneal refractive power after excimer corneal refractive surgery.
