To evaluate the effect of primary and recurrent pterygium surgery on corneal wavefront aberrations.
This prospective and interventional study included the 47 eyes of 47 patients with primary pterygium (primary group) and 41 eyes of 41 patients with recurrent pterygium (recurrent group). All patients underwent pterygium excision with conjunctival autograft transplantation. Corneal wavefront aberrations were measured using Sirius corneal topography and aberrometry system (Costruzione Strumenti Oftalmici, Florence, Italy) before surgery and at 3 and 12 months after surgery. The main outcome measures were root mean square values of total wavefront error (WFE), higher-order aberrations (HOAs), coma, trefoil, and spherical aberrations.
Corneal wavefront aberrations were not significantly different between the primary and recurrent groups at baseline (P>0.05). Total WFE, HOA, trefoil, and coma decreased significantly in both primary and recurrent groups at postoperative 3 and 12 months compared with preoperative measurements (P<0.05). The mean spherical aberration was not significantly changed at 3 and 12 months compared with preoperative measurements (P>0.05). Total WFE, HOA, trefoil, and coma were significantly higher in the recurrent group than in the primary group at postoperative 3 and 12 months (P<0.05).
Pterygium surgery can significantly reduce corneal wavefront aberrations, including total WFE, HOA, trefoil, and coma in eyes with primary or recurrent pterygium. However, postoperative corneal aberrations were higher in the recurrent group than in the primary group.
评估原发性和复发性翼状胬肉手术对角膜波前像差的影响。
这项前瞻性干预性研究纳入了47例原发性翼状胬肉患者的47只眼（原发性组）和41例复发性翼状胬肉患者的41只眼（复发性组）。所有患者均接受翼状胬肉切除联合自体结膜移植术。在手术前以及手术后3个月和12个月，使用Sirius角膜地形图和像差仪系统（意大利佛罗伦萨的Costruzione Strumenti Oftalmici公司）测量角膜波前像差。主要观察指标为总波前误差（WFE）、高阶像差（HOA）、彗差、三叶草像差和球差的均方根值。
原发性组和复发性组在基线时角膜波前像差无显著差异（P>0.05）。与术前测量值相比，原发性组和复发性组在术后3个月和12个月时，总WFE、HOA、三叶草像差和彗差均显著降低（P<0.05）。与术前测量值相比，术后3个月和12个月时平均球差无显著变化（P>0.05）。术后3个月和12个月时，复发性组的总WFE、HOA、三叶草像差和彗差显著高于原发性组（P<0.05）。
翼状胬肉手术可显著降低原发性或复发性翼状胬肉患者眼睛的角膜波前像差，包括总WFE、HOA、三叶草像差和彗差。然而，复发性组术后的角膜像差高于原发性组。
