purpose: to evaluate the effect of posterior residual stroma on visual function after unsuccessful anwar's deep anterior lamellar keratoplasty (dalk). methoods: in this parallel historical cohort, visual acuity and refractive status were evaluated after descemetic dalk (group 1) and compared with those of pre-descemetic dalk (group 2). results: one hundred and ten keratoconic eyes were enr...

purpose: to determine the effect of retained donor descemet membranes (dms) on visual outcomes following deep anterior lamellar keratoplasty (dalk). methods: in this retrospective comparative study, keratoconic eyes undergoing dalk using the big-bubble technique were enrolled. a bared dm was achieved in all cases. a donor cornea without (group 1; 48 eyes) or with (group 2; 22 eyes) dm was sutur...

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 ...

Safe and efficient exposure of Descemet membrane is the key to success in deep anterior lamellar keratoplasty. Although widely used, the big-bubble technique has the drawback of difficulty in maintaining appropriate needle insertion depth in the corneal stroma, resulting in injected air sometimes escaping to the peripheral cornea without separation of Descemet membrane. We describe a variation ...

Purpose To report the first case of acute angle closure due to a high-pressure Descemet membrane detachment following deep anterior lamellar keratoplasty (DALK) using the "big bubble" technique. Observations A 25-year-old man underwent DALK surgery for keratoconus using the "big bubble" technique in which an air bubble is injected in deep stroma to promote dissection of underlying Descemet me...

Descemet membrane detachment (DMD) is a sight-threatening complication that has been reported after diverse surgical procedures. Unilateral DMD typically arises as the result of engagement of the Descemet membrane during intraocular surgery. We report an unusual case of bi latera l DMD occurring spontaneously several weeks after sequential uncomplicated phacoemulsification cataract extraction. ...

Descemet-stripping automated endothelial keratoplasty (DSAEK) has become the procedure of choice to treat corneal endothelial dysfunction. The technique involves replacing the diseased host endothelium with a graft consisting of a thin layer of posterior stroma, Descemet membrane, and endothelium. In comparison to penetrating keratoplasty (PK), DSAEK confers quicker visual and structural recove...

BACKGROUND To report a surgical method for treating corneal oedema in a case of late-onset Descemet membrane detachment after penetrating keratoplasty. CASE PRESENTATION A 55-year old patient presented with sudden visual loss in his left eye 28 years after penetrating keratoplasty for keratoconus. Slit-lamp biomicroscopy revealed a distortion of the corneal graft anatomy with protrusion of th...
