Laser assisted in situ keratomileusis (LASIK) is highly effective for correcting moderate to severe levels of myopia with rapid visual recovery, minimal pain and easier post-operative management compared with Photorefractive keratectomy. Nevertheless, undercorrection may occur. The purpose of this paper is to evaluate 14 undercorrected LASIK cases in which the cap was dissected and the stromal bed re-ablated using a method developed by one of the authors (EM).
Among a series of 297 LASIK procedures, visual and refractive results of 14 cases undergoing enhancement were evaluated. All cases were targeted for plano refraction.
All 14 cases were followed at least 6 months and 7 (50%) have been followed two years. Mean pre-LASIK myopia of -14.60 +/- 4.90 D had been reduced to a mean of -4.50 +/- 2.60 D prior to enhancement. Following enhancement mean spherical equivalent was -0.22 D at 6 months. Results were stable at two years. All cases were within 1.25 D of target and 11 of 14 were within one diopter. Uncorrected vision was improved in all cases. Best corrected vision was maintained or improved in all but one case. This case had a decentered ablation.
Laser enhancement of undercorrected LASIK cases using the Martines Technique was predictable and efficacious.
与准分子激光角膜切削术相比，准分子激光原位角膜磨镶术（LASIK）在矫正中度至重度近视方面疗效显著，视力恢复快，疼痛轻，术后管理更简便。然而，仍可能出现矫正不足的情况。本文旨在评估14例矫正不足的LASIK病例，这些病例采用了作者之一（EM）开发的方法进行瓣切开及基质床再次切削。
在一系列297例LASIK手术中，对14例接受增效手术的患者的视力和屈光结果进行了评估。所有病例的目标屈光状态均为正视。
所有14例患者均随访至少6个月，其中7例（50%）随访了两年。增效术前LASIK平均近视度数为-14.60±4.90 D，增效术前降至平均-4.50±2.60 D。增效术后6个月平均等效球镜度数为-0.22 D。两年时结果稳定。所有病例均在目标度数的1.25 D范围内，14例中有11例在1屈光度以内。所有病例的未矫正视力均有改善。除1例偏心切削病例外，所有病例的最佳矫正视力均得以维持或提高。
采用马丁内斯技术对矫正不足的LASIK病例进行激光增效治疗具有可预测性且疗效显著。
