The emerging space-air-ground integrated network has attracted intensive research and necessitates reliable efficient aeronautical communications. This paper investigates terahertz Ultra-Massive (UM)-MIMO-based communications proposes an effective channel estimation tracking scheme, which can solve the performance degradation problem caused by unique <italic xmlns:mml="http://www.w3.org/1998/Ma...

purpose: to describe the biometric changes and their effect on intraocular lens (iol) power calculation after trabeculectomy and to compare the accuracy of four formulas namely srk/ii, srk/t, holladay and hoffer q for iol power calculation in these patients. methods: thirty-four eyes of 31 glaucoma patients who were scheduled for primary trabeculectomy were enrolled. a non-contact biometry devi...

purpose: to evaluate the safety, efficacy, stability and predictability of posterior chamber collagen copolymer phakic intraocular lens (piol) implantation to correct myopia and myopic astigmatism in keratoconus-affected patients. methods: uncorrected (ucva) and best-corrected (bcva) distance visual acuity, refraction and complications were evaluated in 22 keratoconic eyes of 14 patients who un...

purpose: to compare visual outcomes and surgical complications of three phakic intraocular lenses (piols); artisan, artiflex and the implantable collamer lens (icl) for correction of moderate to high myopia. methods: in this historical cohort study, 112 myopic eyes that were operated between 2005 and 2010 and implanted with one of these three piols were evaluated (artisan 40 eyes, artiflex 36 e...

background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...
