摘要:
目的 觀察伴有中高度散光的近視眼在Toric角膜塑形術后角膜高階像差的變化，以及比較不同直徑范圍下的角膜高階像差的改變情況。 方法 前瞻、隨機選取36例(72眼)伴有中高度散光的近視患者，應用 Pentacam 眼前節(jié)分析系統(tǒng)測量其在Toric角膜塑形術前及塑形1個月后的高階像差，分別記錄角膜前后表面及全角膜的中央3 mm、6 mm直徑的總高階像差及3~6階高階像差。應用 SPSS 19.0統(tǒng)計學軟件進行數(shù)據(jù)分析。 結果 塑形術后角膜前、后表面中央6 mm直徑的總高階像差及3~6階像差的均方根值均明顯增加，與塑形前相比差異均有統(tǒng)計學(P<0.05)，角膜前表面高階像差的增加值高于后表面，其中以4階像差的改變量最大。塑形術后角膜前表面及全角膜的總高階像差、3~6階像差及角膜后表面的總高階像差、3階、4階像差在中央 6 mm范圍直徑的增加量，較中央3 mm范圍直徑的對應高階像差增加量均更為顯著，差異有統(tǒng)計學意義(P<0.05)；塑形術后角膜后表面的5階及6階像差的增加量在中央 6 mm和3 mm范圍直徑下差異無統(tǒng)計學意義(P>0.05)。 結論 Toric角膜塑形術前后，角膜前、后表面各項高階像差均增大，角膜前表面高階像差的變化是引起全角膜高階像差變化的主要因素。角膜塑形術后，角膜前表面及全角膜的高階像差在中央6 mm范圍表現(xiàn)出更大的改變。
Abstract:
Objective To observe the changes of high order aberration(HOA) in myopia with moderate and high astigmatism after toric orthokeratology，and compare the variation of corneal HOA induced by orthokeratology in different measurement diameter.Methods A total of 36 cases (72 eyes) of myopia patients with moderate and high astigmatism were selected prospectively and randomly．The HOA before and one month after toric orthokeratology were measured by Pentacam，and the total HOA and 3-6th order aberrations in central 3 mm and 6 mm diameter ranges on the anterior and posterior surfaces of cornea were recorded separately．The data were analyzed by SPSS 19.0 software．Results After orthokeratology，the root mean square (RMS) values of the total HOA and 3-6 th order aberrations within 6 mm measurement diameter in the center of the anterior and posterior corneal surface were increased significantly (P<0.05)．There were more increment in all HOA on the anterior corneal surface than posterior corneal surface，and the 4th order aberration showed the largest change．The variation of the total HOA and 3-6th order aberrations within 6 mm measurement diameter on the anterior corneal surface and whole cornea were more significant than the corresponding aberrations within 3 mm range (P<0.05)，so were the total HOA，3rd order and 4th order aberrations on the posterior corneal surface．There were no significant differences in increment of 5th order，6th order aberrations between 6 mm and 3 mm measurement range on posterior corneal surface (P>0.05) .Conclusion Before and after toric orthokeratology，the corneal HOA increases，and the change of HOA on anterior corneal surface contributed more．The HOA of cornea in central 6 mm range shows greater variation.
