Thermal photon statistics in laser light above threshold [PDF]

Phys.Rev. A62 (2000) 063807, 1999
We show that the reduction in photon number fluctuations at laser threshold often cited as a fundamental laser property does not occur in typical semiconductor lasers such as the ones commonly used in modern technological applications today. Indeed, such lasers may still exhibit thermal intensity fluctuations far above threshold.

The effect of femtosecond laser-assisted in situ keratomileusis on contrast sensitivity

Frontiers in Neuroscience
The benefits of femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for correcting vision, particularly in terms of spherical equivalent (SE) and visual acuity (VA), have gained broad recognition.

CORONIS symposium 2023: Scientific and clinical frontiers in ocular surface innervation

Acta Ophthalmologica, Volume 103, Issue 4, Page e240-e255, June 2025.
Abstract The 5th CORONIS Symposium, held during the 2023 Congress of the European Association for Vision and Eye Research (EVER), highlighted the growing importance of ocular surface innervation in eye surface disorders. This article summarises the insights and perspectives shared during the symposium, which focused on the clinical relevance of ocular ...

Variation of Bruch's membrane opening in response to intraocular pressure change during scleral lens wear, in a population with keratoconus

Ophthalmic and Physiological Optics, Volume 45, Issue 2, Page 405-415, March 2025.
Abstract Purpose The present study aimed to determine the potential impact of scleral lenses on intraocular pressure (IOP) by analysing the Bruch's membrane opening–minimum rim width (BMO‐MRW) while the lenses are worn, in a population with keratoconus.

Case Series of Perforated Keratomycosis after Laser-Assisted In Situ Keratomileusis

Case Reports in Ophthalmological Medicine, 2020
Background Fungal keratitis is an extremely rare complication of laser vision correction resulting in poor visual outcomes. Amniotic membrane transplantation should be kept in mind in eyes with corneal perforation prior to penetrating keratoplasty.
