The use of screen-enabled handheld devices has increased exponentially during the last few years among the older adults. Up until now, a general suggestion for preventing symptoms of digital eye strain with large screen use was to address any existing refractive error, including presbyopia. It is unclear whether this advice is of consequence in the case of smaller handheld devices.
PURPOSE
The aim of this study was to examine whether correcting presbyopia ameliorates the negative effect on digital screen use, examining handheld devices where these issues are expected to be more acute with presbyopic individuals.
METHODS
This is a cross-sectional study of 120 consecutive participants who had received correction for presbyopia during the past month and returned for a routine follow-up examination. The participants filled in a demographics questionnaire, questions on time spent online and using devices with digital screens, data on their eye complaints, and the validated Digital Eye Strain Questionnaire (DESQ).
RESULTS
The DESQ factor scores and total score correlated with the near addition (P

The dewetting process of contact lenses (CLs) is a result of material and solution properties as well as environmental factors. This article describes an investigational approach to observe and describe dewetting characteristics of different CL material and solution combinations.
PURPOSE
This study aimed to determine the in vitro dewetting characteristics of various daily disposable CLs that were assessed using a noninvasive keratograph dewetting procedure (noninvasive keratograph dry-up time). In vitro dewetting data of the same CL materials soaked in saline solution and artificial tear solution (ATS) were measured to determine additional dewetting characteristics.
METHODS
Noninvasive keratograph dry-up time was measured for six different soft CL materials and three different test conditions, in their specific blister solution, after exposure to saline and an ATS. Twenty CLs of each solution/material combination were assessed after an 8-hour soaking, during a 180-second dewetting observation, and the results were expressed by area under the curve values.
RESULTS
Fastest dewetting occurred for all materials when measured out of saline, indicated by the highest averaged area under the curve value of 9243.3 ± 38.3 over all lens materials. Slower dewetting was detected for all materials when measured out of their specific blister solution (7755.9 ± 37.1) and out of ATS (7988.8 ± 40.0). Intragroup results were statistically significantly different for all solutions showing the smallest differences within the ATS group (P

Nonlinearity in the luminance profile of eccentric, infrared photorefraction may be used to differentiate corneal diseases such as keratoconus that distort the cornea, relative to regular refractive errors.
PURPOSE
This study aimed to determine the profile of eccentric, infrared photorefraction in keratoconus as a prototypical disease model for distorted corneas and identify a parameter in this profile for differentiating such disease conditions from healthy controls.
METHODS
Photorefraction reflex of 75 eyes with forme fruste to advanced keratoconic cases and that of 75 eyes of controls with regular refractive errors (spherical equivalent, +0.50 to −11.75 D; astigmatism, −0.50 to −4.50 D across 0 to 180° axes) were obtained over their natural pupils under unaided viewing using a custom-designed photorefractor placed at 1 m from the subject. The test was repeated in 10 controls with 4 and 6 D of trial-lens–induced myopia and myopic astigmatism at 0, 90, 45, and 135°. Linear regression was performed on the luminance profile across the pupil, and the departure of the data from linearity was estimated using the average residual error of the fit (Resavg).
RESULTS
Photorefraction profiles varied linearly across the pupil in controls, with slopes increasing with refractive error (r = 0.87; P .4). Corresponding profiles in keratoconus significantly departed from linearity, with Resavg progressively increasing with disease severity (r = 0.66; P
