Two patients (three eyes) had previously undergone technically successful radial keratotomy procedures and subsequently sustained blunt injury to the eyes in motor vehicle accidents one and two years after surgery, respectively, with rupture of the cornea along the keratotomy scars. One case subsequently required penetrating keratoplasty to recover 20/50 visual acuity. The second patient died, but had he survived, the extensive ocular injuries would have required significant surgical and medical care to restore vision. Histologic and ultrastructural studies demonstrated incomplete wound healing in the three corneas. Individuals who have had radial keratotomy, like those who have had penetrating keratoplasty, are at increased risk of corneal rupture after direct ocular trauma.
两名患者(三只眼)之前接受了技术上成功的放射状角膜切开术,随后分别在术后一年和两年时,在机动车事故中眼部遭受钝挫伤,角膜沿角膜切开术瘢痕处破裂。其中一例随后需要进行穿透性角膜移植术以恢复至20/50的视力。第二名患者死亡,但如果他存活下来,其广泛的眼部损伤将需要进行大量的手术和医疗护理来恢复视力。组织学和超微结构研究表明,三只角膜的伤口愈合不完全。接受过放射状角膜切开术的人,与接受过穿透性角膜移植术的人一样,在直接眼部外伤后发生角膜破裂的风险增加。
