摘      要：To present the use of automated lamellar therapeutic keratoplasty (ALTK) for t he treatment of post-photorefractive keratectomy (PRK) corneal scarring and thi nning with significant residual myopia. Interventional case report. A patient wi th high myopia of-12 diopters previously underwent PRK that resulted in corneal scarring, myopic regression, moderate loss of best-corrected visual acuity, a residual refractive error of -6.50/-1.00 ×.175 degrees, and a remaining corneal thickness of 300 μm. ALTK was first performed to remove the scar and to augment corneal thickness, and a subsequent laser-assisted in-situ keratomi leusis (LASIK) procedure was performed to correct the residual myopia. ALTK effe ctively removed the corneal scar and augmented the corneal thickness to 639 μm. LASIK effectively treated the residual myopia, resulting in an unaided visual a cuity of 20/25 and a stable refractive error of plano/-0.50 ×40 degrees. The A LTK interface remained clear throughout the follow-up period of 26 months. ALTK may be a reasonable alternative to conventional penetrating keratoplasty in the treatment of post-PRK corneal scarring and thinning, with a moderate loss of b est-corrected visual acuity, and LASIK can be subsequently performed to correct the residual refractive error and achieve an excellent refractive and visual ou tcome.
