Traumatic hyphema after radial keratotomy

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.
