purpose: to describe a new noninvasive method to assure correct orientation of donor lenticules in descemet stripping automated endothelial keratoplasty (dsaek) surgery. methods: dsaek surgery was performed in three eyes with the diagnosis of pseudophakic bullous keratopathy (pbk). for the laboratory part of the study, two whole globes and two precut corneoscleral buttons were used. the donor l...

Endothelial keratoplasty is at present the gold standard for surgical treatment of corneal endothelial pathologies not associated with significant corneal scar. Tremendous progress has been made in recent years in improving the technology of endothelial keratoplasty techniques, such as descemet stripping automated endothelial keratoplasty (DSAEK) and descemet membrane endothelial keratoplasty. ...

purpose: to investigate the biomechanical features of transplanted corneas after penetrating keratoplasty (pk), deep anterior lamellar keratoplasty (dalk), and descemet stripping automated endothelial keratoplasty (dsaek) and compare these measurements with those of a normal group. methods: forty-five eyes of 36 patients underwent pk, 23 eyes of 21 patients received dalk using anwar’s big bubbl...

DeepVein Thrombosis FollowingDescemet Stripping Automated Endothelial Keratoplasty Venous thromboembolism is the secondmost commonmedical complication after surgery.1 The risk factors for development of deepvein thrombosis (DVT) include age, obesity, and diabetesmellitus.1Deepvein thrombosis associatedwithophthalmic surgery, specifically vitreoretinal surgery, has been reported.2 Descemet strip...

Endothelial keratoplasty is now favored over full-thickness penetrating keratoplasty for corneal decompensation secondary to endothelial dysfunction. Although endothelial keratoplasty has evolved as surgeons strive to improve outcomes, fewer patients than expected achieve best corrected visual acuity of 20/20 despite healthy grafts and no ocular comorbidities. Reasons for this remain unclear, w...

mated Bowman layer preparation with a 90to 100-mm-thick donor lamella of anterior stroma (instead of an 8to 12-mm-thick isolated Bowman layer graft). In our experience, the presence of donor stroma seems to degrade the optical quality of the transplanted cornea (as Descemet stripping endothelial keratoplasty/Descemet stripping automated endothelial keratoplasty grafts containing donor stroma ma...

OBJECTIVE To describe the use of a single donor corneal tissue in 3 patients with corneal pathologic conditions. METHODS A donor corneal tissue was divided into 3 parts using a microkeratome and a trephine. The anterior lamellar disc was transplanted into a patient with macular corneal dystrophy using the automated lamellar therapeutic keratoplasty technique. The posterior lamellar disc was t...

OBJECTIVE To investigate how precise Descemet stripping works in posterior lamellar keratoplasty (Descemet stripping automated endothelial keratoplasty [DSAEK]) for the treatment of corneal endothelial disorders. METHODS In a prospective, single-center, nonrandomized consecutive series, 20 Descemet membrane specimens obtained after Descemet stripping in DSAEK using a Price hook were examined ...

We present the case of a 57-year-old woman who had combined Descemet-stripping automated endothelial keratoplasty (DSAEK) and phacoemulsification with implantation of a toric intraocular lens (IOL). Surgery was intended to treat a cataract developing in a post-penetrating keratoplasty (PKP) eye with high astigmatism and endothelial decompensation. Six months after uneventful surgery, the cornea...
