Big-bubble technique to bare Descemet's membrane in anterior lamellar keratoplasty.

摘要: We describe a lamellar keratoplasty technique to bare Descemet's membrane in which air is injected detach the central Descemet's. After partial-thickness corneal trephination performed, disposable needle inserted, deeply and bevel down, into paracentral stroma injected. In most cases, this forms large bubble between stroma. anterior keratectomy small opening made remaining stromal layers are lifted with an iris spatula, severed blade, excised scissors. This faster, safer, easier perform than previous methods.
