Dysfunctional lens syndrome (DLS) is a term coined to describe the natural aging changes
in the crystalline lens. Different alterations in the refractive properties and transparency of …

Background We assessed the effects of aging on visual function and optical quality in a
healthy adult population and provide reference values for different age ranges. Methods We …

Purpose To quantitate lens nuclear opacity using long-range swept-source optical
coherence tomography (SS-OCT) images and to evaluate the correlation of this method to …

Purpose: To study the correlations between subjective and objective cataract metrics with
dysfunctional lens index. To investigate the potential of the DLI as a novel surgery decision …

Background A cataract is a common cause of vision impairment that requires surgery in
older subjects. The Optical Quality Analysis System (OQAS, Visiometrics SL, Terrassa …

Cataract is among the most common ophthalmic conditions in the world and the leading
cause of decreased visual acuity (VA). 1 Unsurprisingly, cataract surgery is the most …

Purpose To determine the cut-off points for age and metrics provided by cataract grading
objective systems for which a reestablishment in contrast sensitivity (CS) is expected after …

Background The dysfunctional lens index (DLI) provided by a ray-tracing aberrometry
system is an objective index in cataract assessment. The purpose of this study is to evaluate …

ABSTRACT A previous work has reported a methodology to quantify intraocular scattering
using a high sensitivity double-pass instrument with a robust index, the frequency scatter …

Purpose To assess the correlation between clinical cataract surgery indication and the
objective scatter index (OSI) by defining the optimal OSI cutoff point in the surgery …
