Congenital hereditary endothelial dystrophy (CHED), presents in infancy or early childhood with bilateral clouding of corneas. This condition has previously been managed surgically with penetrating keratoplasty (PKP). Performing PKP in pediatric patients has its own set of difficulties. More recently, there has been growing interest in treating this condition with Descemet's stripping automated...

Neurotrophic keratopathy (NTK) is an orphan, polyetiological disease that has recently been identified more frequently. Drug-resistant stages of NTC often require urgent surgical treatment. Subsequently, such patients need to be done keratoplasty, the consequences may unsatisfactory in presence a significant impairment innervation. Purpose : evaluate effectiveness lamellar anterior keratoplasty...

After preliminary testing with pig, dog, rabbit, monkey, cat, and human cadaver eyes the CLCC system has been used for penetrating and lamellar keratoplasty in human subjects. Clinical experience covers a broad range of corneal pathology. Detailed operative instructions and observations are given. In the experimental situation the CLCC is being used to achieve deep lamellar corneal dissection f...

PURPOSE The purpose of this study is to report a case of microsporidial endophthalmitis after penetrating keratoplasty in a healthy patient and discuss the management. METHODS This is a case report. RESULTS A 69-year-old healthy male underwent penetrating keratoplasty for corneal scar secondary to herpes stromal keratitis. He presented with features of acute graft rejection 3 years later. A...

Aim: To improve the deep lamellar keratoplasty technique. Method: For the easy and reliable perfomance of deep lamellar keratoplasty (DLKP), detachment of Descemet’s membrane through the corneal limber flap was improved. To expose Descemet’s membrane, the parenchyma was detached by hydrodelamination through a sclerocorneal flap made in the corneal limbs. The parenchyma was removed after the pse...

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...

PURPOSE To report and discuss cases of lamellar keratoplasty using corneas obtained during previous penetrating keratoplasty in keratoconus eyes. METHODS Corneal buttons were obtained from 7 keratoconus patients and stored in a preserving solution for 7-60 days (average, 32.4 days) before use. The recipient eyes comprised recurrent pterygium 3 eyes, primary pterygium 1 eye, pseudopterygium 1 ...

Current treatment for corneal endothelial dysfunction consists in the replacement of endothelium by keratoplasty. Owing to scarcity donor corneas and increasing number transplants, alternative treatments such as cell-based therapies are necessary. In this article, we highlight biological aspects cornea endothelium, well context that surrounds need new alternatives conventional We then review so...

We describe a technique using deep anterior lamellar keratoplasty (DALK) in 5 eyes that developed keratectasia after LASIK. The technique is based on surgical manipulation that allows visualization of the lamellar dissection depth using a posterior approach to reach the predescemetic space. The mirror effect, indentation effect, and folding effect were used to determine proximity to Descemet's ...

Penetrating keratoplasty carries an infectious risk. Its requirement for topical corticosteroid therapy facilitates fungal growth with resulting keratitis. Although progression of fungal keratitis to intraocular infection is uncommon, endophthalmitis resulting from keratitis usually has a poor visual prognosis. Fungal infection under these circumstances remains a diagnostic and therapeutic chal...
