METHODS: From January 2001 to October 2002, 21 high myopia patients (39 eyes) with borderline corneal thickness were treated with LASIK. Visual acuity, keratometry readings and central corneal thickness were measured at 3 years after surgery. These data were compared with preoperative and early postoperative results.

选2001-01/2002-10在我院行LASIK手术的高度近视相对薄角膜患者21例39眼，查术后3a的视力、眼压、屈光状态、角膜曲率及中央角膜厚度，并与术前及术后早期数据进行统计学比较分析。

Keratometry measurements were obtained preoperatively, at postoperative 1 week, 1 month and 6 months respectively. SIAs were analyzed by "Cravy vector method". The mean SIA and uncorrected visual acuity were compared among the groups up to 6 months postoperatively.

测量术前、术后1周、1、3和6个月的角膜曲率，运用Cravy向量分析法计算SIA度数及方向，比较3组术后不同时间的平均SIA度数及裸眼视力。

Keratometry was measured with corneal topography,corneal central thickness and eye axis were measured with type A ultrasonic machine,and the data were statistically analysed with Excel 97 software.

在进行PRK治疗的患者中，根据屈光度将278例(538只眼)患者分成低、中、高和超高度四组，应用角膜地形图仪测定角膜屈光力，A型超声波测定眼轴及角膜中央厚度，数据用Exce 197软件计算处理。

The long-term outcomes of highly myopic patients with borderline corneal thickness after LASIK were less stable and predictable. The regression was probably related to the preoperative refraction, age, corneal thickness and keratometry readings.

高度近视薄角膜患者LASIK术后的远期稳定性较低，可预测性较差，术后屈光回退可能与术前屈光、年龄、角膜厚度和曲率的改变有关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
