Herein we describe a technique for management of large inadvertent full-thickness trephination during deep anterior lamellar keratoplasty using the big-bubble technique without converting to penetrating keratoplasty. First, the anterior chamber is formed with an ophthalmic viscosurgical device (OVD). Then, the full-thickness wound is secured with one X-type 10-0 nylon suture. A 27-gauge needle ...

OBJECTIVE We describe a modified technique for performing lamellar dissection in deep anterior lamellar keratoplasty after failure to achieve a "big bubble" detachment of Descemet's membrane (DM) with deep intrastromal pneumatic injection. METHODS The technique utilizes blunt lamellar dissection with blunt-tipped corneal mini scissors as an alternative to a crescent blade, which can be diffic...

purpose: to report the possible transmission of zygomycetes infection by a corneal graft harvested from a donor with signs of trauma to the orbital region to a keratoconic patient who underwent deep anterior lamellar keratoplasty (dalk). case report: a 19-year-old keratoconic man underwent dalk in the right eye. the corneal graft was harvested from a donor with signs of orbital trauma. on posto...

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...

BACKGROUND The purpose of this paper is to describe a technique of donor cornea preparation to ensure good graft-host apposition in incomplete big bubble deep anterior lamellar keratoplasty. METHODS Following a partial-thickness trephination, manual dissection and excision of corneal stroma was performed. Anwar's big-bubble technique involving a deep stromal air injection was then initiated. ...

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 compare visual outcomes after deep anterior lamellar keratoplasty (dalk) between eyes with and without successful big-bubble formation. methods: in this retrospective comparative study, a total of 290 consecutive eyes from 257 keratoconus-affected patients underwent dalk with the big-bubble technique were enrolled. in cases where the big bubble could not be accomplished, manual stro...

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...

purpose: to evaluate visual outcomes after deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this interventional case series, patients with moderate to advanced keratoconus underwent dalk. inclusion criteria consisted of contact lens intolerance or poor spectacle-corrected visual acuity. dalk was performed using the big-bubble technique introduced by anwar and...
