What is DLK in eyes?
Diffuse lamellar keratitis (DLK) describes a rare, noninfectious complication of refractive surgery that is characterized by inflammatory infiltrates beneath the corneal flap interface.
What causes DLK?
Proposed causes of DLK include particles from the eye drape, epithelial defects, meibomian secretions, surgical glove talc, debris from surgical sponges, and contamination of reservoir sterilizers by gram-negative endotoxins, among others.
What is DLK paper?
ISRI Circular 2013: (13) New Double-Lined Kraft Corrugated Cuttings (DLK) Consists of new corrugated cuttings having liners of either test liner or kraft. Treated medium or liners*, insoluble adhesives, butt rolls, slabbed or hogged medium, are not acceptable in this grade.
How long does inflammation last after LASIK?
Corneal swelling, known as corneal edema, is common during the LASIK recovery period. For most patients, swelling in the cornea is temporary and will resolve on its own over the course of a few weeks. In some cases, swelling may continue for one or two months, but seldom is edema an issue after week eight.
How do you reduce inflammation after LASIK?
Inflammation under the LASIK flap is called diffuse lamellar keratitis. This occurs when white blood cells sneak under the flap. We put all patients on anti-inflammatory drops that decrease the level of irritation and inflammation after LASIK.
What is lamellar surgery?
Lamellar keratoplasty is an operation in which diseased corneal tissue is removed and replaced by lamellar corneal tissue from a donor. The procedure is performed either to improve vision (optical keratoplasty) or to provide structural support for the cornea (tectonic keratoplasty).
What is OCC scrap?
The OCC Scrap is used to recycle to make new corrugated boxes. The OCC Scrap can be made available in medium as well as bulk quantities across any destination in the world. We have special arrangements for quick shipment of the scrap.
What are the different grades of paper?
In addition to pulp, the “furnish” from which book papers are made contains various amounts of sizing, fillers, and dyes. Uncoated book paper comes in four finishes: (1) antique or eggshell, (2) machine finish, MF, (3) English finish, EF, and (4) supercalendered. Antique has the roughest surface.
What are the signs and symptoms of DLK?
DLK is a potentially serious, sight-threatening complication. It may be associated with redness, sensitivity to light, tearing, pain, and reduced vision. DLK is classified by four stages depending on the severity and location of the inflammation.
What causes DLK in the eye after LASIK?
Proposed causes of DLK include particles from the eye drape, epithelial defects, meibomian secretions, surgical glove talc, debris from surgical sponges, and contamination of reservoir sterilizers by gram-negative endotoxins, among others.
What should you do if you have DLK and flap melt?
DLK should be immediately treated with topical steriods. If DLK progresses it may require surgical intervention. Severe cases of DLK may progress to flap melt with associated vision loss.
