Comparison of corneal flap thickness using a FS200 femtosecond laser and a moria SBK microkeratome [PDF]

open access: yesInternational Journal of Ophthalmology, 2014
AIM: To evaluate differences in flap thickness resulting from use of an Alcon Wavelight FS200 femtosecond laser and a MORIA SBK microkeratome when making a 110-μm-thick corneal flap and to identify the potential factors that affect corneal flap thickness.

Evaluation of corneal biomechanical properties in spherical and toric soft contact lens wear

open access: yesMedical Journal of Dr. D.Y. Patil Vidyapeeth, 2022
Purpose: Corneal hysteresis (CH) and corneal resistance factor was found to be less for patient wearing toric contact lens as compared to soft spherical CH was calculated as the difference in air pressures between force-in applanation (P1) and force-out ...

Central Corneal Thickness in Latinos

open access: yesInvestigative Opthalmology & Visual Science, 2003
To characterize central corneal thickness (CCT) in Latinos aged 40 or more years.A population-based cohort of Latinos from two census tracts in La Puente, California, underwent measurements of CCT and intraocular pressure (IOP). CCT was measured with an ultrasonic pachymeter, and IOP was measured by applanation tonometry.
