Femtosecond-Cut Allogenic Corneal Tissue Addition Keratoplasty for the Treatment of Post-LASIK Ectasia

Purpose: This study reports a case of femtosecond-cut allogenic corneal tissue addition keratoplasty (CTAK) for the management of advanced post-LASIK ectasia in a scleral contact lens–intolerant patient. Methods: A case report of a 45-year-old woman with post-LASIK ectasia and prior corneal cross-linking underwent CTAK using a custom-designed femtosecond-cut allogenic corneal inlay. Results: At 1 month postoperatively, spectacle-corrected visual acuity improved from LogMAR 1.3 to 0.2, with significant corneal flattening (Kmean reduction of 9.7D). Conclusions: CTAK offers a promising surgical option for scleral contact lens–intolerant post-LASIK ectasia patients, potentially delaying or avoiding the need for corneal transplantation while providing significant visual and topographic improvement.
