摘要
目的:报道准分子激光原位角膜磨镶术(laserinsitu keratomileusis,LASIK)术后发生的双眼圆锥角膜1例,探讨此类并发症的预防和处理。方法:通过病例报道的方法,结合国内外的相关报道,分析继发性圆锥角膜发生的原因和处置的有效性。结果:1位30岁的女性患者在术前检查无任何圆锥角膜征象的情况下行常规LASIK手术,术后2.5a视力严重下降,裂隙灯检查发现双眼角膜呈典型的圆锥改变,角膜地形图显示下方角膜明显前突。配戴硬性角膜接触镜后矫正视力达1.0。结论:详细的术前检查和计算,术中角膜瓣和基质床厚度的准确测量,以及术后的定期随访是预防圆锥角膜的发生的重要措施。在发生圆锥角膜后,适当的处理对于恢复患者的视力至关重要。
· AIM: To describe a case of bilateral keratoconus occurring after laser in situ keratomileusis (LASIK) and to discuss the prevention and treatment of this kind of complication.· METHODS: The cause and treatment efficiency of se- condary keratoconus were analyzed by case report and articles review.· RESULTS: A 30-year-old female with no topographic signs of keratoconus preoperatively presented to our institution for dramatic vision decreasing 2.5a after undergoing bilateral LASIK for the treatment of compound myopic astigmatism. A slitlamp examination revealed classic signs of keratoconus, and a corneal topography examination showed marked bilateral inferior protrusion. The best corrected visual acuity (BCVA) were 1.0 in both eyes after rigid gas permeable (RGP) contact lenses were used.· CONCLUSION: Preoperative examination and calculation, accurate measurement of flap and residual corneal thickness during operation, and timely following up are important for the prevention of keratoectasia development. After diagnosis, appropriate treatments are essential for the visual acuity recovery.·
