To evaluate the results obtained with the treatment for interface epithelial ingrowth after laser in situ keratomileusis (LASIK) with neodymium:yytrium-aluminum-garnet (Nd:YAG) laser.
Retrospective, interventional, noncomparative, consecutive case series.
Thirty eyes were treated with Nd:YAG laser for clinically significant epithelial ingrowth developed after LASIK. Each impact produced an explosion with evaporation of epithelial cells giving rise to bubbles. The mean intensity of the spots was 0.6 mJ, and they were variable in quantity depending on the size of the epithelial ingrowth area. The patients were followed up for two years.
The opacities caused by the epithelial ingrowth disappeared in 80% of the cases with the Nd:YAG laser treatment. In 40% of the cases, two or more sessions of Nd:YAG laser treatment were necessary to eliminate the epithelial ingrowth areas entirely. In 60% of the cases, visual acuity improved by one or more lines of vision and the corneal topography was more regular. After the treatment, symptoms like glare and halos improved in all cases. The intensity of the laser was adjusted in each case and was focused perfectly on the epithelial ingrowth areas. There were no complications.
Nd:YAG laser, in our experience, is an easy and effective technique for the treatment of epithelial ingrowth after LASIK.
评估用钕:钇铝石榴石(Nd:YAG)激光治疗准分子原位角膜磨镶术(LASIK)后界面上皮内生的效果。
回顾性、介入性、非对比性、连续病例系列。
30只眼睛接受Nd:YAG激光治疗,这些眼睛在LASIK术后出现了具有临床意义的上皮内生。每次冲击都会产生爆炸,使上皮细胞蒸发形成气泡。光斑的平均强度为0.6 mJ,数量根据上皮内生区域的大小而变化。对患者进行了两年的随访。
Nd:YAG激光治疗后,80%的病例中上皮内生引起的混浊消失。40%的病例需要进行两次或更多次Nd:YAG激光治疗才能完全消除上皮内生区域。60%的病例视力提高了一行或多行,角膜地形图更规则。治疗后,所有病例的眩光和光晕等症状均有所改善。在每个病例中都调整了激光强度,并完美地聚焦在上皮内生区域。没有出现并发症。
根据我们的经验,Nd:YAG激光是治疗LASIK后上皮内生的一种简便有效的技术。
