目的:探讨LASIK术前周边视网膜变性区行预防性激光凝固术(光凝)治疗的必要性。方法:对831例1631眼进行LASIK术前常规检查,发现患有严重周边视网膜变性49眼,其中裂孔17眼、格子样变性15眼、囊样变性26眼,均行532nm固体激光预防性光凝治疗。结果:光凝术后1mo视网膜光凝斑形成有效色素沉着后行LASIK手术。术后经3～36mo随访未发现变性灶扩大及治疗区域以外裂孔形成。结论:LASIK术前对所有患者进行详细的眼底检查是必要的,当发现严重周边视网膜变性进行预防性光凝是安全、有效的。

AIM:To study the necessity of laser photocoagulation before laser in situ keratomileusis(LASIK) on the retinal degeneration. METHODS:Totally 49 eyes(49/1631) showed serious peripheral fundus degeneration after routine preoperative examination of 831 cases.Retinal tears were found in 17 eyes,lattice retinal degeneration in 15 eyes and cystoid retinal degeneration in 26 eyes.All of them have been treated with laser photocoagulation by 532nm solid laser. RESULTS:One month after laser photocoagulation, LASIK surgery was performed in laser region which has good pigmentation.There were no complications of retinal detachment during the follow-up period of 3-36 months. CONCLUSION:Detailed examination of fundus before LASIK is necessary.The preventative laser photocoagulation in serious peripheral fundus degeneration is safe and effective.
