Blunt scissors stromal dissection technique for deep anterior lamellar keratoplasty

Blunt scissors stromal dissection technique for deep anterior lamellar keratoplasty

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...

Dissection technique in lamellar keratoplasty.

A new surgical technique for deep stromal, anterior lamellar keratoplasty.

AIMS To describe a new surgical technique for deep stromal anterior lamellar keratoplasty. METHODS In eye bank eyes and sighted human eyes, aqueous was exchanged by air, to visualise the posterior corneal surface--that is, the "air to endothelium" interface. Through a 5.0 mm scleral incision, a deep stromal pocket was created across the cornea, using the air to endothelium interface as a refe...

New technique of Deep Anterior Lamellar Keratoplasty

Deep anterior lamellar keratoplasty (DALK) is a surgical technique for cornea replacement, which the healthy host corneal endothelium is preserved. Keratoconus patients are those who benefit most from a successful DALK procedure, once the endothelium of these patients is usually normal and should therefore be maintained. Several studies comparing visual outcomes between penetrating keratoplasty...

Small-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 ...
