Big bubble DALK after CXL in keratoconic patients.
Collagen cross-linking (CXL) is being offered to a growing number of keratoconic patients worldwide for prevention of disease progression, with an overall success rate that exceeds 90% of the treated eyes.1,2 However, some patients do continue to progress after CXL and may need to undergo keratoplasty. Deep anterior lamellar keratoplasty (DALK) has become the preferred technique by an increasin...
متن کاملEasy Bubble: Pachymetry-assisted Big-Bubble Deep Anterior Lamellar Keratoplasty
We present a simple, effective and reproducible technique for deep anterior lamellar keratoplasty. Using a diamond knife, set at 90% of corneal thickness (90 degrees meridian), at the limbus a radial incision was made and a corneal pocket was created. A specially designed cannula was placed deep into the corneal stroma and air was injected for stromal dissection. The air bubble pushed down Desc...
متن کاملVisual Outcomes of Successful versus Failed Big-Bubble Deep Anterior Lamellar Keratoplasty for Keratoconus
PURPOSE To compare the visual outcomes of deep anterior lamellar keratoplasty (DALK) for keratoconus with and without successful big-bubble formation. METHODS In this retrospective comparative study, a total of 289 consecutive eyes from 257 patients underwent DALK using the big-bubble technique. In cases where the big bubble could not be accomplished, manual stromal dissection down to Desceme...

purpose : to review the visual outcome and complications of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique in patients with corneal ectasia methods : eighteen consecutive patients with keratoconus or post-lasik ectasia with poor spectacle-corrected visual acuity and/or contact lens intolerance were enrolled in this study between october 2005 and september 2006. dalk b...
متن کاملSmall-bubble deep anterior lamellar keratoplasty technique.
Stromal disease (ectasia, opacities, scars, or melting) that occurs after penetrating keratoplasty (PK) can variously affect visual outcome.1,2 To date, even in the presence of healthy endothelium, this typeof complicationhasbeen treatedwith subsequentPK.3 Instead, the selective replacement of the diseased stroma by means of deep anterior lamellar keratoplasty (DALK) using pneumatic dissection ...
