A cornea transplant (keratoplasty) is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye. It's where light enters your eye and is a large part of your eye's ability to see clearly. A cornea transplant can restore vision, reduce pain, and improve. Doctors often do this type of surgery to help Fuchs' dystrophy and other medical conditions. Descemet's stripping endothelial keratoplasty (DSEK or DSAEK) is the most common type of endothelial.

Corneal transplantation, or keratoplasty, is a surgery that replaces your poorly functioning cornea with a new donated one. The cornea is the clear front part of the eye that allows light to enter. It also helps focus light into your eye. Different medical problems can damage your cornea The choice of type of anesthesia for a penetrating keratoplasty depends on patient-specific factors and the surgeon's comfort levels. If a patient expresses anxiety and is likely to move around during the surgery, the surgeon may seriously consider general anesthesia. Alternatively, some ophthalmic centers routinely perform all penetrating keratoplasties with MAC and a peri- or retrobulbar block Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft).

  1. Endothelial keratoplasty (EK) is a cornea transplant technique that is the preferred way to restore vision when the inner cell layer of the cornea stops working properly from Fuchs' dystrophy, bullous keratopathy, iridocorneal endothelial (ICE) syndrome, or other endothelial disorders.EK selectively replaces only the diseased layer of the cornea, leaving healthy areas intact
  2. Conductive keratoplasty works by using radio-frequency (non-laser) energy that is strategically delivered to the cornea by a small probe. A tiny probe applies heat to the outer cornea at the precise area where astigmatism reduction is needed. The heat causes a local tightening effect against astigmatism, which can reduce astigmatism and improve.

An endothelial keratoplasty is an eye operation in which the innermost layer, or endothelium, of the cornea is removed and replaced by donor tissue. The cornea is the transparent covering of the eyeball, and this type of corneal transplantation may become necessary when diseases such as Fuch's endothelial dystrophy damage the endothelium Background. Deep anterior lamellar keratoplasty (DALK) has become an important alternative to conventional penetrating keratoplasty for disorders of the corneal stroma, mainly keratoconus and scars. 1 The main advantage of this technique is the preservation of the host's endothelium and thereby a reduced risk of immunological graft rejections. Because keratoconus is the most common reason for.

Traditionally, penetrating keratoplasty (PKP) has been performed to restore visual acuity with excellent result in MCD. 1,10 However, due to the risk of endothelial rejection and intraocular complications, several anterior lamellar keratoplasty techniques have been described such as deep anterior lamellar keratoplasty (DALK). Big bubble. l disease and its associated operative challenges, several modifications in the surgical approach have been developed. Identified predictive factors for successful pneumatic dissection and intraoperative complications have informed surgical planning and decision-making. In the setting of failed pneumatic dissection, sequential use of alternative lamellar dissection techniques is a reasonable.

Therapeutic penetrating keratoplasty achieves anatomic success and it is a useful procedure for restoring a stable cornea in cases in which infection fails to heal or when the cornea perforates. Furthermore, Th PK achieves corneal clarity and improves vision in most patients. Eye & Contact Lens44:S433-S441, November 2018 Purpose In this paper, we describe two cases of fungal interface infectious keratitis (IIK) developed after endothelial keratoplasty (EK) who underwent delayed therapeutic penetrating keratoplasty (TPK) with a poor visual outcome. Furthermore, we conducted a review of the literature and analyzed the visual outcomes of TPK in relation to the time from IIK diagnosis. Methods We searched the. keratoplasty, stressing particularly the valueoflamellar transplants (Paufique, 1946). Lamellar keratoplasty, so admirable in suitable cases, is very much under-rated even today. Both in lamellar and penetrating keratoplasty, simplicity of technqiue was the keynote ofsuccess, a point stressed byLeigh (I954) Eyes that undergo Descemet's membrane endothelial keratoplasty (DMEK) appear to have a higher rate of cystoid macular oedema (CME) compared to eyes that undergo Descemet-stripping automated endothelial keratoplasty, following endothelial keratoplasty, according to a study presented by Luca Furiosi MD at the 25th ESCRS Winter Meeting Faculty Lecture: Recent Advances in Anterior Lamellar Keratoplasty by Prof. Radhika Tandon Faculty Lecture: Update on Posterior Lamellar Keratoplasty by Prof. Namrata Sharma 102 View Pre Descemet's endothelial keratoplasty (PDEK) is a kind of endothelial keratoplasty, where the pre descemet's layer (PDL) along with descemet's membrane (DM) and endothelium is transplanted. Conventionally in a corneal transplantation, doctors use a whole cornea or parts of the five layers of the cornea to perform correction surgeries.In May 2013, Dr Harminder Dua discovered a sixth layer.
