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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Ocular growth and lens size

    Författare :Ulla Kugelberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :congenital cataract; lens thickness; intraocular implants; ocular axial length; corneal diameter; infant eye; rabbit eye;

    Sammanfattning : Ocular axial length growth was investigated with special reference to the influence of crystalline lens and different intraocular lens implants, in human infants and three week-old rabbits. First it was concluded, in a retrospective study of children with bilateral congenital cataract, that lensectomy during the first months of life resulted in almost normal visual development. LÄS MER

  4. 3. Inflammatory response after cataract surgery : randomized controlled clinical and laboratory studies of different surgical techniques

    Författare :Carl-Gustaf Laurell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cataract extraction; phacoemulsification; inflammation; blood-aqueousbarrier; anti-inflammatory agents; heparin surface modified intraocular lens; fluorophotometry; prostaglandins; after-cataract; corneal oedema; lasers; comparative study; randomize;

    Sammanfattning : During the last few years the phacoemulsification technique for cataract extraction has improved considerably. Because of this development phacoemulsification has recently superseded extracapsular cataract extraction (ECCE) as the preferred method. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. On Aniridia in Sweden and Norway

    Författare :Ulla Edén; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gillespie syndrome; Aniridia; PAX6 gene;

    Sammanfattning : Introduction Aniridia (iris more or less missing), is a congenital, dominant, inherited, serious and sight-threatening disease, most often appearing as an isolated eye disorder. It is caused by mutations in the PAX6 gene, the master gene of the development of the eye. Typically, Aniridia causes severe visual impairment. LÄS MER
