The effect of severe blunt trauma to the human eye six months after radial keratotomy is discussed. After the injury, the patient initially had a 4-mm corneal abrasion, a 75% hyphema of the anterior chamber, and no noted damage to the corneal structure. After six months of follow-up the patient had a confirmed 20% angle recession with traumatic iridoplegia, an uncorrected vision of 6/4.5 (20/15), and a corrected vision of 6/4.5 (20/15). At no time has there been evidence of rupture to the incision sites or damage to the corneal structure. From this case study, it seems likely that the effect of trauma on deep corneal incisions as performed in radial keratotomy does not adversely affect the corneal integrity of the human eye after six months.
本文讨论了放射状角膜切开术后六个月时人眼遭受严重钝挫伤的影响。受伤后，患者最初有4毫米的角膜擦伤、前房积血75%，且角膜结构未发现损伤。经过六个月的随访，患者确诊有20%的房角后退并伴有外伤性虹膜麻痹，未矫正视力为6/4.5（20/15），矫正视力为6/4.5（20/15）。切口部位从未有破裂迹象，角膜结构也未受损。从该病例研究来看，放射状角膜切开术中所做的深层角膜切口在六个月后似乎不会对人眼角膜完整性产生不利影响。
