Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

HYALURONIC ACID DERIVATIVE MICELLES AS OCULAR PLATFORMS TO DRUG RELEASE AND CORNEAL PERMEATION

2016

In traditional ocular formulations, only small amount of the administered drug penetrates the cornea to reach the intraocular tissue. One approach to improve the drug ocular bioavailability was to develop colloidal drug delivery systems. Polymeric micelles seem to be very promising for their capacity to dissolve a variety of hydrophobic drugs by enhancing their water solubility and so their bioavailability. They are able to increase ocular drug permeability due to interact with the complex corneal structure. Considering the advantages to use mucoadhesive polymer to increase drug residence time on the ocular surface, the aim of this work was to prepare hyaluronic acid-based micelles as a pla…

Pēcoperācijas perioda izvērtējums pēc radzenes transplantācijas vispārējā anestēzijā

2020

Bakalaura darba tēma ir “Pēcoperācijas perioda izvērtējums pēc radzenes transplantācijas vispārējā anestēzijā”. Darba tēmas aktualitāte ir tajā, ka radzenes transplantācijas operācijas visā pasaulē un Latvijā tiek veiktas arvien vairāk, tāpēc ir būtiski novērtēt pēcoperācijas periodu pēc šīm operācijām, lai izvērtēt aprūpes procesu, pacientu sūdzības un dokumentācijas kvalitāti un nepieciešamības gadījumā veikt uzlabojums. Darba mērķis ir izvērtēt pēcoperācijas periodu pacientam pēc radzenes transplantācijas operācijas vispārējā anestēzijā. Bakalaura darba mērķa saniegšanai autore izvirzija sekojošus darba uzdevumus - apkopot un analizēt zinātnisko literatūru par radzenes transplantāciju un…
