Improvement in refractive precision for intraocular lens power calculations in patients with a history of laser vision correction for myopia
Gjerdrum, Bjørn (Doctoral dissertations at the University of South-Eastern Norway;99, Doctoral thesis, 2021-05-28)In Cataract surgery and refractive lens exchange (RLE) planning, calculations of intraocular lens (IOL) power depend on, at a minimum, the measurement of corneal curvature and the axial length of the eye. In patients without ... -
Presbyopic refractive lens exchange with trifocal intraocular lens implantation after corneal laser vision correction: Refractive results and biometry analysis
Brenner, Louis; Gjerdrum, Bjørn; Aakre, Bente Monica; Lundmark, Per; Nistad, Kristin (Peer reviewed; Journal article, 2019)Purpose: To evaluate the refractive and biometry results of presbyopic refractive lens exchange (RLE) with trifocal intraocular lens (IOL) implantation in eyes with previous myopic or hyperopic corneal laser vision correction ... -
Prevalence of signs and symptoms of dry eye disease 5 to 15 after refractive surgery
Gjerdrum, Bjørn; Gundersen, Kjell Gunnar; Lundmark, Per; Potvin, Rick; Aakre, Bente Monica (Peer reviewed; Journal article, 2020)Purpose: To compare the prevalence of dry eye disease (DED) as determined by signs and symptoms in patients with a history of laser vision correction (LVC) or implantable collamer lens (ICL) implantation 5–15 years ago ... -
Repeatability of OCT-Based versus Scheimpflug- and Reflection-Based Keratometry in Patients with Hyperosmolar and Normal Tear Film
Gjerdrum, Bjørn; Gundersen, Kjell Gunnar; Lundmark, Per Olof; Aakre, Bente Monica (Peer reviewed; Journal article, 2020)Purpose: To compare the repeatability of keratometry between different instruments in patients with hyperosmolar tear film and a control group. Patients and Methods: Subjects with tear-film osmolarity of 316 mOsm/L or ...
