Name of journal: American journal of ophthalmology case reportsAbstract: Conclusion and importance: Epithelium-off CXL is used increasingly to treat post-LASIK ectasia. First, in this case, DLK occurred after epi-off CXL. We suggest careful scrutiny of such cases as DLK is difficult to identify after epi-off CXL. Second, the epi-off CXL was unsuccessful in stopping the post-LASIK ectasia. Transepithelial CXL successfully treated the ongoing ectasia after resolution of the DLK with no subsequent re-occurrence of DLK. We suggest that TE-CXL may provide a successful initial treatment for post-LASIK ectasia that also minimizes the epithelial disruption that can lead to DLK.Observations: A 42-year-old man presented with corneal ectasia in his right eye 3 years after laser in situ keratomileusis (LASIK) surgery. He underwent epi-off corneal CXL using the Dresden protocol. Grade II DLK was diagnosed within days of CXL. Despite successful treatment of DLK, best-corrected visual acuity in the right eye deteriorated over the next 4 months due to progression of ectasia and remained worse than the patient's pre-operative baseline 1 year after epi-off CXL. Because of apparent disease progression, despite his CXL treatment, the patient underwent a novel, transepithelial CXL (TE-CXL) treatment combined with conductive keratoplasty (CK). This treatment improved his vision and stabilized his ectasia without subsequent DLK. Approximately 3 years after CK and TE-CXL, his eye remains stable with 4 Snellen lines of improved vision and no progression of ectasia.Purpose: To report diffuse lamellar keratitis (DLK) occurring in an eye that underwent epithelium-off (epi-off) corneal cross-linking (CXL) as a treatment for post-surgical ectasia and the successful treatment of progressive ectasia with a novel epi-on CXL and conductive keratoplasty (CK) treatment.All authors: Jun AS, Mannschreck DB, Rubinfeld RS, Soiberman USFiscal year: FY2019Digital Object Identifier: Date added to catalog: 2019-03-14

Conclusion and importance: Epithelium-off CXL is used increasingly to treat post-LASIK ectasia. First, in this case, DLK occurred after epi-off CXL. We suggest careful scrutiny of such cases as DLK is difficult to identify after epi-off CXL. Second, the epi-off CXL was unsuccessful in stopping the post-LASIK ectasia. Transepithelial CXL successfully treated the ongoing ectasia after resolution of the DLK with no subsequent re-occurrence of DLK. We suggest that TE-CXL may provide a successful initial treatment for post-LASIK ectasia that also minimizes the epithelial disruption that can lead to DLK.

Observations: A 42-year-old man presented with corneal ectasia in his right eye 3 years after laser in situ keratomileusis (LASIK) surgery. He underwent epi-off corneal CXL using the Dresden protocol. Grade II DLK was diagnosed within days of CXL. Despite successful treatment of DLK, best-corrected visual acuity in the right eye deteriorated over the next 4 months due to progression of ectasia and remained worse than the patient's pre-operative baseline 1 year after epi-off CXL. Because of apparent disease progression, despite his CXL treatment, the patient underwent a novel, transepithelial CXL (TE-CXL) treatment combined with conductive keratoplasty (CK). This treatment improved his vision and stabilized his ectasia without subsequent DLK. Approximately 3 years after CK and TE-CXL, his eye remains stable with 4 Snellen lines of improved vision and no progression of ectasia.

Purpose: To report diffuse lamellar keratitis (DLK) occurring in an eye that underwent epithelium-off (epi-off) corneal cross-linking (CXL) as a treatment for post-surgical ectasia and the successful treatment of progressive ectasia with a novel epi-on CXL and conductive keratoplasty (CK) treatment.
