Time-resolved refractive index and absorption mapping of light-plasma filaments in water

, 2007
By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma filament generated by a 100 fs laser pulse in water.

Comparison of automated corneal endothelial cell analysis in healthy and postoperative eyes with phakic intraocular lens: a cross-sectional study and literature review

BMC Ophthalmology
Purpose Measurement of corneal endothelial cells is critical for postoperative evaluation of phakic intraocular lens (pIOL) surgery. However, inter-instrument differences in corneal endothelial cell density (ECD) after pIOL implantation have not yet been

Keratorefractive lenticule extraction (KLEx) versus femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for the treatment of myopia and compound myopic astigmatism: study protocol of a randomised clinical trial in Mexico

BMJ Open
Introduction Kerato-lenticule extraction (KLEx) is a refractive surgery technique that, in contrast with femtosecond laser-assisted in situ keratomileusis (FS-LASIK), does not require the creation of a flap to correct refractive defects.
