PURPOSE: To describe Descemet membrane endothelial keratoplasty (DMEK) complications and strategies for their prevention and management. METHODS: Five hundred consecutive eyes with DMEK of 393 patients were reviewed in this retrospective study for intraoperative and postoperative complications up to 2 years and for corresponding management. RESULTS: Intraoperative challenges (difficult graft unfolding/positioning, high vitreous pressure, iris root hemorrhage, and Descemet membrane remnants) were encountered in 81 eyes (16...

PURPOSE: To investigate the long-term outcomes of penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) after ocular surface stem cell transplantation (OSST). METHODS: An observational retrospective review was performed on all patients who underwent OSST followed by either PK or DALK with a minimum of 6-month follow-up. RESULTS: One hundred two eyes fulfilled the inclusion criteria. The mean time to keratoplasty after OSST was 19 months, and the mean follow-up was 57 months after keratoplasty...

PURPOSE: To report a mutation of CYP1B1 in a newborn with a rare phenotype without the classic features of anterior segment dysgenesis or congenital glaucoma. METHODS: The newborn presented with diffuse corneal edema and bilaterally elevated intraocular pressure (IOP). Ophthalmological examination, ultrasound, and ultrasound biomicroscopy were performed; congenital infections were ruled out. Genetic analysis was performed. The patient underwent penetrating keratoplasty and goniotomy in a single surgical time...

PURPOSE: To describe a simple technique that uses posterior chandelier illumination during Descemet membrane endothelial keratoplasty in cases of severe bullous keratopathy (BK). METHODS: Five eyes of 4 patients with advanced BK undergoing Descemet membrane endothelial keratoplasty were retrospectively analyzed. The pupil of the host eye was not treated with mydriatic or miotic agents. The chandelier illuminator was inserted transconjunctivally into the vitreous cavity from the pars plana...

BACKGROUND: Residency training is the basis of good clinical and surgical practice. PURPOSE: The aim is to know the demographics, training experience, and perception of young ophthalmologists to improve the present residency programs in India. SETTING: Young ophthalmologists trained in India. METHODS: A survey was conducted by the Academic and Research Committee of the All India Ophthalmology Society, in 2014-2016 of young ophthalmologists (those trained between 2002 and 2012, with 2-10 years' postresidency experience) to gauge teaching of clinical and surgical skills during the postgraduate residency program...

Bacterial keratitis is a serious ocular infectious disease that can threaten vision. The disease generally progresses rapidly and can lead to corneal scar, stromal abscess formation, perforation, and dissemination to adjacent tissues if not treated properly. Recent studies showed that corneal collagen crosslinking (CCC) using ultraviolet-A/riboflavin is effective in the treatment of bacterial keratitis refractory to topical antibiotic treatment. In addition to being bactericidal, CCC also decreases risk of perforation by strengthening the corneal collagen structure...

PURPOSE: The aim of the study was to evaluate the various donor and recipient factors associated with short-term prevalence of surface epithelial keratopathy after optical penetrating keratoplasty (OPK). METHODS: Preoperative and postoperative data of 91 eyes of 91 patients were reviewed retrospectively who had undergone OPK from March 2013 to February 2016. Donor and recipient data were analyzed for age and sex of the donor, cause of death, death to enucleation time (DET), death to preservation time (DPT), enucleation to utilisation time (EUT) and total time (TT), age and sex of recipient, indications of penetrating keratoplasty (PK), associated glaucoma and recipient size (RS)...

REVIEW
J-L Bourges
Degenerative or hereditary corneal diseases are sometimes difficult to discriminate. Corneal dystrophies affect approximately 0.09 % of the population. They are identified by the IC3D classification based on their phenotype, genotype and evidence gathered for their diagnosis. Practically, the ophthalmologist manages functional symptoms, such as recurrent erosions, visual loss and amblyopia, photophobia, foreign body sensation, and sometimes pain and aesthetic concerns. Medical treatments consist of drops to promote healing, ointments, hyperosmotic agents and bandage contact lenses...

Bin Xu, Zhan Song, Tingjun Fan
Tissue-engineered human anterior hemi-cornea (TE-aHC) is a promising equivalent for treating anterior lamellar keratopathy to surmount the severe shortage of donated corneas. This study was intended to construct a functional TE-aHC with nontransfected human corneal stromal (ntHCS) and epithelial (ntHCEP) cells using acellular porcine corneal stromata (aPCS) as a carrier scaffold, and evaluate its biological functions in a dog model. To construct a TE-aHC, ntHCS cells were injected into an aPCS scaffold and cultured for 3 days; then, ntHCEP cells were inoculated onto the Bowman's membrane of the scaffold and cultured for 5 days under air-liquid interface condition...

A 68-year-old woman presented with infectious crystalline keratopathy 4 months after she underwent a combined phacoemulsification and Descemet's stripping endothelial keratoplasty for Fuch's endothelial dystrophy in her left eye. After 5 months of topical moxifloxacin 1%, the infiltrate responded well but had not completely resolved, with the resulting endothelial failure requiring a penetrating keratoplasty 9 months after the initial operation. Microbiology identified Enterococcus faecalis with the histopathology demonstrating bacterial colonies within the graft interface...

BACKGROUND: Conjunctival flaps are a widely used treatment for numerous corneal ulcers that are caused by microorganismal infections. However, whether it can be performed on immune-mediated corneal ulcers is controversial. CASE PRESENTATION: We present two cases of Mooren's ulcer that were treated using conjunctival flap in an attempt to prevent further corneal perforation at their local hospital. A rapid acceleration in ulcer progression was observed after a conjunctival flap was applied...

INTRODUCTION: Epithelial invasion after open globe injury is a rare complication. Wrong treatment (laser opening of the cyst) or no treatment can lead to painful blindness. PATIENTS AND METHODS: Forty percent (25/62) of patients with block excision with epithelial downgrowth had a history of open globe injury. Four of them were female. Their mean age was 45 ±21 years. RESULTS: A tectonic keratoplasty with block excision was performed on 25 patients...

Lorenzo J Cervantes
A slight modification to the Yamane transconjunctival double-needle flanged-haptic technique of intrascleral fixation of an intraocular lens (IOL) shows the technique's usefulness when combined with Descemet-stripping endothelial keratoplasty (DSEK). The modification uses bipolar cautery to create flanges at the tip of the IOL haptics and delays tucking the haptics into the scleral tunnels until DSEK has been completed. Bipolar cautery enables the technique to be used in situations in which disposable low- or high-temperature cautery, as originally described, might not be possible...

The management of severe keratoconus requires corneal transplantation, for which the gold standard is deep anterior lamellar keratoplasty (DALK), preserving the healthy Descemet's membrane and endothelium. The safety and reproducibility of corneal cuts have been improved by the evolution of femtosecond lasers in refractive surgery, and femtosecond laser in DALK would seem to provide the same advantages over the manual method. In our retrospective study, we compare functional and anatomical results of femtosecond-assisted DALK versus manual trephination DALK in patients with keratoconus in stage 4 of the Krumeich classification...
