Purpose. To compare the effect of 60 kHz and 150 kHz femtosecond (FS) laser on the corneal stromal bed surfaces (SBS). Methods. Sixteen human donor corneal tissues unsuitable for transplantation were used. Anterior and posterior lamella was obtained using 60 kHz and 150 kHz FS laser. A standard depth of 400  μ m was set for anterior lamellar keratoplasty (ALK) and endothelial lamellar keratopla...

RATIONALE To report a case of late spontaneous reattachment of Descemet membrane (DM) detachment after deep anterior lamellar keratoplasty (DALK). PATIENT CONCERNS A 50-year-old woman with stromal corneal scarring underwent a DALK with the big bubble technique. The DM detachment and double anterior chamber were observed on the first day after operation. DIAGNOSES Descemet membrane detachmen...

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...

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...

392 A 17‐year‐old female with a several‐year history of bilateral keratoconus was visited about 1 year prior to deep anterior lamellar keratoplasty (DALK) in her right eye (OD). History‐wise, she was intolerant to glasses and contact lenses and her past medical history and family history were unremarkable. On ocular examination, she had visual acuity (VA) of 2 meters counting fingers (CF) in ea...

PURPOSE To evaluate and record the common complications that face surgeons when they perform their first few series of deep lamellar keratoplasty and measures to avoid these. SETTING Dar El Oyoun Hospital, Cairo, Egypt. METHODS Retrospective study of the first 40 eyes of 40 patients carried out by two corneal surgeons working in the same center. All patients were planned to undergo a deep a...

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 ...
