Optical Quality Assessment in Patients with Macular Diseases Using Optical Quality Analysis System

Visual Quality Assessment of Posterior Capsule Opacification Using Optical Quality Analysis System (OQAS)

Objective To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods In this prospective, observational, and n...

Assessment of Tear Film Optical Quality Dynamics.

PURPOSE To investigate tear film optical quality dynamics by analyzing the postblink temporal changes of objective scatter index (OSI). METHODS A total of 109 myopic subjects without symptoms of dry eye and 32 myopic subjects diagnosed with dry eye disease were recruited in this cross-sectional study. The right eye for each subject was analyzed. Serial measurements of OSI were performed for 2...

Micro-Optical Fluidic Analysis System for Environmental and Quality Control

A microfluidic analysis system based on photometric measurements is presented. Feasibility of photometric analysis in silicon flow channels has been shown using commercially available reagents and a microspectrometer. Quantitative determination of iron and phosphate in water in the concentration range around the legal limit for drinking water has been carried out as an example. An integrated an...

Assessment of Macular Parameter Changes in Patients with Keratoconus Using Optical Coherence Tomography

Keratoconus is typically diagnosed through changes at the anterior ocular surface. However, we wished to assess if macular parameter changes might also occur in these patients. We assessed posterior changes through the use of optical coherence tomography and compared to a nonkeratoconus patient group. All subjects underwent clinical examination including macular thickness measurements. The gene...
