Extensive Descemet membrane detachment (DMD) is a rare complication of intraocular surgery that can lead to corneal decompensation. Although DMD may resolve spontaneously, surgical repair frequently is required. The diagnosis may be difficult because corneal edema can obscure visualization of the Descemet membrane (DM). Ultrasonographic biomicroscopy (UBM) has been the standard for imaging DMD ...

PURPOSE To describe a case of traumatic wound dehiscence after deep anterior lamellar keratoplasty. METHOD Observational case report. CASE REPORT A 31-year-old man who had undergone deep anterior lamellar keratoplasty using big-bubble technique for keratoconus 3 months earlier presented to emergency room after blunt trauma.On examination, visual acuity was counting fingers at 2 m. The corne...

Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even...

Cultures of whole fetal rat sensory ganglia which had matured and myelinated in culture were treated for 1-3 h with a pulse of 0.2% trypsin. The tissue was observed during the period of treatment and during subsequent weeks using both light and electron microscopy. Within minutes after trypsin addition the matrix of the culture was altered and the nerve fascicles loosened. Progressive changes i...

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...

We describe a technique for performing deep lamellar keratoplasty using viscoelastic dissection. Deep lamellar dissections of the cornea using viscoelastic substances (sodium hyaluronate) were performed on 4 eyes of 4 patients. One patient with keratoconus and another with corneal scarring underwent lamellar keratoplasty using the technique as the sole procedure for visual rehabilitation. Two p...

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...

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...
