Intraocular pressure changes and corneal biomechanics after hyperopic small-incision lenticule extraction

open access: yesBMC Ophthalmology, 2020
Background We aimed to compare the intraocular pressure (IOP) measurements by a dynamic Scheimpflug analyzer (Corvis ST), a non-contact tonometer, and an ocular response analyzer after hyperopic small-incision lenticule extraction (SMILE).

Screening of Forme Fruste Keratoconus with the Ocular Response Analyzer

open access: yesInvestigative Opthalmology & Visual Science, 2010
To evaluate the performance of the Ocular Response Analyzer (ORA) in the screening of forme fruste keratoconus (FFKc).A retrospective comparative study was conducted involving 180 eyes. ORA preoperative data were analyzed for 125 normal control eyes (64 patients) undergoing laser in situ keratomileusis (LASIK) without corneal ectasia after 24 months of

Corneal biomechanics and intraocular pressure changes after uneventful phacoemulsification surgery

open access: yesJournal of the Egyptian Ophthalmological Society, 2019
Background Biomechanics of the cornea is represented by corneal hysteresis (CH), which is defined as the viscous damping owing to viscoelastic resistance of the cornea to deformation.

ANATOMO-TOPOGRAPHIC AND HYDRODYNAMIC PARAMETERS OF THE EYE AFTER CATARACT PHACOEMULSIFICATION

open access: yesAlʹmanah Kliničeskoj Mediciny, 2016
Background: Removal of the native lens alters spatial relationships between anterior eyeball structures and results in fluctuations in intraocular pressure. Intraocular pressure control is important for the prevention of early postoperative complications.
