Correction of hyperopia following radial keratotomy: quantification in human cadaver eyes

Overcorrection is a significant complication following radial keratotomy (RK). This study using human cadaver eyes demonstrates that the use of interrupted sutures placed across radial incisions coincident with a 7-mm optical zone mark can induce a wide range of central corneal steepening and can therefore correct varying amounts of hyperopia following RK. A case presentation confirms the effectiveness of using interrupted sutures to steepen the cornea following RK, but it also shows that significant regression of the effect must be considered at the time of suture placement. Since placement of interrupted corneal sutures is a routine procedure, it is a very convenient technique for treating overcorrection following RK.
