    To correct both corneal thinning and induced corneal astigmatism, the authors propose a modified intrastromal lamellar sclero-keratoplasty. A stromal lamellar graft is inserted into an intrastromal pocket through a scleral tunnel.

    Sclerocorneal intrastromal lamellar keratoplasty (SILK) is efficient in pellucid marginal degeneration (PMD). Corneal thinning is corrected with the intrastromal lamellar keratoplasty, and scleral tunnel closure allows increased corneal astigmatism correction. Perioperative OCT guidance allows better detection of the diseased cornea and is helpful for the lamellar dissection.
