Journal ArticleDOI
A new optical low coherence reflectometry device for ocular biometry in cataract patients
Phillip J Buckhurst,James S. Wolffsohn,Sunil Shah,Shehzad A. Naroo,Leon N. Davies,Emma J. Berrow +5 more
TL;DR: The LenStar biometric measurements were found to be highly repeatable and the instrument easy to use and there were some statistical differences between ocular biometry measurements between the LenStar and current clinical instruments, but they were not clinically significant.
Journal ArticleDOI
Clinical evaluation of the Shin-Nippon NVision-K 5001/Grand Seiko WR-5100K autorefractor.
TL;DR: The open-view arrangement of the Shin-Nippon NVision-K 5001 facilitates the measurement of static refractive error and the accommodative response to real-world stimuli and is a valuable addition to objective instrumentation currently available to the optometrist and researcher.
Journal ArticleDOI
Clinical evaluation of the Grand Seiko Auto Ref/Keratometer WAM-5500.
Amy L. Sheppard,Leon N. Davies +1 more
TL;DR: A clinical evaluation of the Grand Seiko Auto Ref/Keratometer WAM‐5500 (Japan) was performed to evaluate validity and repeatability compared with non‐cycloplegic subjective refraction and Javal–Schiotz keratometry.
Journal ArticleDOI
Presbyopia: Effectiveness of correction strategies
TL;DR: A redefinition of presbyopia is proposed that states “presbyopia occurs when the physiologically normal age‐related reduction in the eye's focusing range reaches a point, when optimally corrected for distance vision, that the clarity of vision at near is insufficient to satisfy an individual's requirements”.
Journal ArticleDOI
Clinical evaluation of rebound tonometer.
TL;DR: Measurement of IOP in normal, healthy subjects using the ICare rebound tonometer produced a small, statistically insignificant, positive bias when compared with the Goldmann tonometer.
