The feasibility of managing ectasia after small-incision lenticule extraction (SMILE) using tissue addition and pocket corneal crosslinking (CXL) is described. Four eyes of 3 patients (mean age 25.7 years) developed features of keraectasia at a mean period of 3 years after SMILE for myopia. All cases were managed with insertion of heterologous SMILE lenticules in the previously created pocket, followed by simultaneous accelerated CXL. At a mean follow-up of 7.67 months, there was improvement in corrected distance visual acuity and reduction in keratometry and higher-order aberrations in all eyes. The visual, refractive, and topographic parameters remained stable at the last visit compared with the 2-week follow-up visit. No eye developed haze, infection, or rejection requiring tissue explantation. Early experience showed tissue addition with simultaneous pocket CXL to be a feasible approach for managing ectasia after SMILE. However, further follow-up is required to establish the long-term safety and effects on corneal stabilization.
