DSAEK package software
For use with Descemet Stripping Automated Endothelial Keratoplasty (DSAEK)
DSAEK is a partial thickness cornea transplant procedure that involves selective removal of the patient’s Descemet membrane and endothelium, followed by transplantation of donor corneal endothelium in addition to donor corneal stroma.(Figure 8). The transplanted tissue is approximately 100-200 microns thick. If the endothelium of the graft makes contact with any surgical instruments, it will be damaged and the graft may fail; therefore, the surgical procedure is designed to avoid contacting the donor endothelium. A tunneled corneoscleral incision is created, the recipient endothelium and Descemet membrane is removed, the graft is folded and inserted with non-coapting forceps (forceps that do not meet at the tips), and an air bubble is placed in the anterior chamber to support graft adherence. The procedure is used to treat corneal edema in the setting of endothelial dystrophies (such as Fuchs corneal dystrophy and posterior polymorphous corneal dystrophy), pseudophakic bullous keratopathy, iridocorneal endothelial (ICE) syndrome, endothelial failure in the setting of prior intraocular surgery or of a previous PK graft, and other causes of corneal endothelial dysfunction (1, 17-20).
LRI package software
Limbal Relaxing Incisions (LRI) are a refractive surgical procedure to correct minor astigmatism in the eye. Incisions are made at the opposite edges of the cornea, following the curve of the iris, causing a slight flattening in that direction. Because the incisions are outside of the field of view, they do not cause glare and other visual effects that result from other corneal surgeries like Radial Keratotomy. LRI have become the most common technique to correct astigmatism as part of cataract surgery. They are simpler and less expensive than laser surgery such as LASIK or photorefractive keratectomy. Good results do not require the location and length of the incisions to be highly precise. And the incisions can easily be extended later if the original procedure did not correct all of the astigmatism. Recovery is generally quick and painless, although the patient may experience discomfort.
