摘　　要：目的评价透气性硬性角膜接触镜(RGPCL)矫正LASIK手术后角膜后表面膨隆屈光异常的临床疗效。方法 LASIK手术后角膜后表面膨隆患者12例24只眼,配戴RGPCL。随访24个月观察患者视力、角膜曲率、角膜后表面DIFF值、配适状况、舒适度及并发症。结果患者配戴RGPCL后,矫正视力明显提高,矫正视力≥1.0以上12只眼(50.0%),矫正视力0.4～0.9 12只眼(50.0%)。配戴RGPCL 24个月后的矫正视力与初始戴RGPCL矫正视力的差异有显著意义(P<0.05)。与配戴RGPCL前比较,戴RGPCL 2年后角膜后表面DIFF值均有不同程度的降低,差异有显著意义(P<0.05);配戴RGPCL前后角膜厚度变化差异无显著意义(P>0.05)。所有患者配适良好,均无明显合并症发生。结论 RGPCL能够改善LASIK手术后角膜后表面曲率,是目前矫正LASIK术后角膜后表面膨隆的有效方法。Objective To evaluate the efficacy and safety of rigid gas permeable contact lens in correcting the expansion of corneal posterior sur- face occurred after LASIK surgery. Methods A prospective descriptive study was carried out from May 1,2005 to May 1,2008. Twelve patients （24 eyes） that suffered expansion of corneal posterior surface after LASIK surgery underwent the therapy of rigid gas permeable contact lens. The data of visual acuity, corneal curvature, DIFF value of corneal surface posterior, adaption levels, comfort and complications were collected and ob- tained for a follow - up of 24 months. Results The corrected visual acuity of the patients was significantly improved after they wore RGPCL. Twelve eyes （50%） have a corrected visual acuity 1. 0 and the rest 12 eyes between 0. 4 and 0. 9. The difference between the corrected visual acuities when the patients had worn RGPCL for 24 months and when they started to wear RGPCL was statistically significant （ P 〈 O. 05 ）. The anterior corneal surface and corneal surface DIFF values dropped to different extents after the patients had worn RGPCL for two years, and the differences were statistically significant （P 〈 O. 05 ）. The change in corneal thickness was not significant （P 〉 O. 05）. All patients were well adapted to RGPCL, and no obvious complication occurred. Conclusions Being able to improve the corneal posterior surface curvature, RGPCL is presently an effective method to correct the cor- neal posterior surface bulge suffered by patients having taken LASIK surgery.
