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...

Pellucid marginal degeneration is characterized by a progressive stromal thinning of the inferior corneal segment, between 4 and 8 o'clock, with a crescentic shape. The area of corneal thinning has a width of about 1 to 2 mm, and it is separated from the corneoscleral limbus by an area of normal corneal tissue. The initial treatment consists of optical correction. However, when the disease prog...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...
