2. 1. Inflammation and wound healing following photorefractive keratectomy

   Author : Santiago Tomás Barberán; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Photorefractive keratectomy; excimer laser; inflammation; flare; prostaglandins; diclofenac; dexamethasone; pain; epithelial healing; corneal topography; growth factors; metalloproteinases; collagen; haze; haze distribution; Scheimpflug system; Laser Flare Meter; regression; reoperation; wound healing;

   Abstract : This study comprises different aspects on the inflammatory and wound healing responses of the eye after Photorefractive Keratectomy (PRK). The purpose was to provide basic information about the inflammatory reaction and the wound healing after surgery. PRK is considered a good technique for surgical correction of and moderate myopia.

4. 2. Refractive surgery with the ArF excimer laser (photorefractive keratectomy) : surgical technique, wound healing and refractive results

   Author : Heléne Hamberg-Nyström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Photorefractive keratectomy; excimer laser; comparison; centration; contrast sensitivity; night vision; endothelial cell; epithelial thickness; multipassmultizone; multizone; haze; saccades; hyaluronan; myopic regression; reoperation; wound healing.;

   Abstract : Excimer lasers have been adapted to treat refractive errors in the human eye since 1987. By remodeling the corneal surface, myopia and astigmatism can be corrected. The investigations herein were performed during a time period when the surgical technique development was extensive. READ MORE

5. 3. Corneal cellular proliferation and wound healing

   Author : Lisha Gan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : cornea; cell proliferation; wound healing; stem-cells; leukocytes; PCNA; hyaluronan; alkali injury; photorefractive keratectomy;

   Abstract : Background: Cellular proliferation plays an important role in both physiological and pathological processes. Epithelial hyperplasia in the epithelium, excessive scar formation in retrocorneal membrane formation and neovascularization are examples of excessive proliferation of cornea cells. Lack of proliferative ability causes corneal degeneration. READ MORE

6. 4. Water, hyaluronan and surface shape in corneal wound healing after excimer surgery : experimental studies

   Author : Beat A Weber; Karolinska Institutet; Karolinska Institutet; []
   Keywords : photorefractive keratectomy; excimer laser; rabbit; cornea; wound healing; microradiography; hyaluronan; planimetry; leukocyte protein marker; haze; regression; surface irregularities; subepithelial deposits; remodeling; epithelial hyperplasia; corticosteroids;

   Abstract : Excimer laser photorefractive keratectomy (PRK) has evolved to a widely performed procedure. The excimer laser corrects refractive ametropias by removing a calculated amount of anterior corneal stroma with great precision and with minimal damage to the adjacent tissues. The correction of myopia up to -5. READ MORE

7. 5. Applanation Resonance Tonometry for Intraocular Pressure Measurement

   Author : Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
   Keywords : Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

   Abstract : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. READ MORE
