PURPOSE
To examine whether LASIK induces changes in the optic disc and retinal nerve fiber layer using scanning laser tomography.
METHODS
Prospective, consecutive study of 53 myopic eyes in 38 patients (mean age: 35.7 +/- 10.4 years; range: 22 to 58 years). Preoperative average refractive error was -6.0 +/- 2.4 diopters (D) (spherical equivalent) (range: -2.0 to -10.0 D). Optic disc morphology and retinal nerve fiber layer thickness were evaluated with scanning laser tomography preoperatively and at 7 and 13 months postoperatively.
RESULTS
No statistically significant differences were noted between the pre- and postoperative optic disc and retinal nerve fiber layer measurements.
CONCLUSIONS
Our results suggest that transient extreme elevation of intraocular pressure during LASIK does not affect the optic disc morphology or retinal nerve fiber layer thickness in normal myopic eyes for at least 1 year after surgery.
目的
使用扫描激光断层扫描术检查准分子原位角膜磨镶术（LASIK）是否会引起视盘和视网膜神经纤维层的变化。
方法
对38例患者的53只近视眼进行前瞻性、连续性研究（平均年龄：35.7±10.4岁；范围：22至58岁）。术前平均屈光不正为-6.0±2.4屈光度（D）（等效球镜）（范围：-2.0至-10.0 D）。术前以及术后7个月和13个月时，使用扫描激光断层扫描术评估视盘形态和视网膜神经纤维层厚度。
结果
术前和术后视盘及视网膜神经纤维层测量结果之间未发现统计学上的显著差异。
结论
我们的结果表明，LASIK术中眼内压的短暂极端升高在术后至少1年内不会影响正常近视眼的视盘形态或视网膜神经纤维层厚度。
