Purse String Suturing for Post Radial Keratotomy Hyperopia

Radial keratotomy (RK) in 1980s had. been considered to be a reasonable treatment for low to moderate degrees of myopia. The main complication of RK over the ensuing postoperative years has been refractive instability and progressive hyperopia. In our case report, we describe the technique of intrastromal purse string suturing using 9-0 poplypropylene suture in a case of post RK high hyperopia 20 years after the initial surgery. The uncorrected distance visual acuity (UCDVA) improved from 1.1 LogMAR preoperatively to 0.3 LogMAR within one month with a significant and stable steepening on the corneal topography four months post suturing.
