Reliability of manual segmentation of cornea, contact lens and tear film using a high-resolution OCT
2015
In this study, we aimed to evaluate the intra/inter-session and intra/inter-observer variability of manual segmentation of thickness of the pre-lens tear film, contact lens (CL), post-lens tear film, epithelium, bowman’s layer, stroma and the whole cornea and CLs with a flat and a steep fit, using a commercial high-resolution spectral domain optical coherence tomographer (OCT). Two different observers obtained three repeated measures in two separate sessions. A high correlation was found between the values obtained by the two different observers, except for the thinner layers, epithelium, and Bowman’s layer. Inter-observer analysis showed a high consistency in the measurements obtained by b…
Proclear EP vs placebo: visual outcomes and symptoms of asthenopia in nonpresbyopes and early presbyopes
2011
Purpose: Over the past 20 years, many studies have reported the success of multifocal contact lenses (MFCLs) compared to monovision (MV), with only partial success being reported for MFCLs. Chronologically it appears there has been a gradual improvement in the performance of MFCLs. This study investigated whether this change in success is reflected in clinical practice. Method: Lens fit data collected from 2005 to 2009 by the International Contact Lens Prescribing Survey Consortium was reviewed for patients over 45 years old. A similar survey conducted from 1988 to 1989 was also reviewed and compared. Twelve published (Pubmed.gov) reports of clinical trials involving MFCLs and MV were revie…
