Popis: PURPOSE To describe a surgical technique to achieve the desired plane during deep anterior lamellar keratoplasty (DALK) in eyes with Descemet membrane (DM) tears due to previous hydrops. METHODS This was a prospective, consecutive, interventional case series of DALK in 12 keratoconic eyes with healed hydrops. Dissection of the peripheral cornea was performed by air injection and using the microbubble incision technique as a guide to the clear predescemetic stroma. The central posterior scar was then removed by peeling to bare DM. RESULTS DALK was successfully completed in all eyes, with DM tears ranging from a microperforation to approximately 4 mm. At 12 months, the mean logMAR best-corrected visual acuity was 0.38 ± 0.07, the mean keratometric astigmatism was 5.2 ± 1.9 diopters, and the mean endothelial cell density was 2364 ± 316.9 cells/mm. CONCLUSIONS Peripheral pneumatic dissection and central scar peeling technique is a useful technique to complete DALK in eyes with scars due to previous hydrops.
