Pupil dependence assessment with multifocal intraocular lenses through visual acuity and contrast sensitivity defocus curves.

Purpose: To identify the most sensitive visual performance metric for evaluating the pupil-dependency of a multifocal intraocular lens (MIOL) and to determine the pupil measurement method most correlated with such metric.

Systematic review of potential causes of intraocular lens opacification.

Intraocular lens (IOL) opacification is an infrequent complication of cataract surgery. Surface analysis has demonstrated that the opacification of IOLs is related to calcium or phosphate precipitation on or within the lenses, but the associated mechanisms are unknown, and the scientific literature is heterogeneous and limited to case series and retrospective studies. The purpose of this systematic review was to analyse the most frequent conditions associated with opacification of IOLs reported by studies.

New Approach for the Calculation of the Intraocular Lens Power Based on the Fictitious Corneal Refractive Index Estimation.

Purpose: To identify the sources of error in predictability beyond the effective lens position and to develop two new thick lens equations.

Methods: Retrospective observational case series with 43 eyes. Information related to the actual lens position, corneal radii measured with specular reflection and Scheimpflug-based technologies, and the characteristics of the implanted lenses (radii and thickness) were used for obtaining the fictitious indexes that better predicted the postoperative spherical equivalent (SE) when the real effective lens position (ELP) was known.

From Presbyopia to Cataracts: A Critical Review on Dysfunctional Lens Syndrome.

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 the lens are produced during the development of presbyopia and cataract, such as changes in internal high order aberrations or an increase in ocular forward scattering, with a potentially significant impact on clinical measures, including visual acuity and contrast sensitivity. Objective technologies have emerged to solve the limits of current methods for the grading of the lens aging, which have been linked to the DLS term.

Prediction of surgically induced astigmatism in manual and femtosecond laser-assisted clear corneal incisions.

Purpose: To assess the surgically induced astigmatism with femtosecond laser-assisted and manual temporal clear corneal incisions and to evaluate the performance of a model for prediction of the surgically induced astigmatism based on the preoperative corneal astigmatism.

Methods: Clinical data of 104 right eyes and 104 left eyes undergoing cataract surgery, 52 with manual incisions and 52 with femtosecond laser-assisted incisions in each eye group, were extracted and revised retrospectively. In all cases, manual incisions were 2.

The Diagnosis of Hereditary Angioedema: Family Caregivers' Experiences.

An interpretive and qualitative research methodology based on Gadamer's philosophical hermeneutics was carried out. Data collection took place between May 2015 and August 2016 and included a focus group and in-depth interviews with 16 family caregivers.

Biometric Factors Associated with the Visual Performance of a High Addition Multifocal Intraocular Lens.

Unlabelled: Purpose/Aim: To evaluate the impact of ocular parameters on the visual performance achieved with the multifocal intraocular lens (IOL) Bi-Flex M 677MY.

Materials And Methods: About 26 subjects were included in the current study. Several physiological variables were retrieved from the 3-month follow-up visit, including pupil diameter and distance from pupil center to the vertex normal of the anterior cornea (µ).

Agreement and repeatability of objective systems for assessment of the tear film.

Purpose: To assess the agreement and repeatability of two objective systems for measuring the tear film stability.

Methods: Retrospective analysis of the tear film stability of 99 healthy right eyes measured with a videokeratoscope (VK) and the Optical Quality Analysis System (OQAS, Visiometrics). Two consecutive measures were taken with both systems, with an interval of 10 min between them.

Corneal biomechanics after laser refractive surgery: Unmasking differences between techniques.

The hypothesis that small-incision lenticule extraction provides better preservation of corneal biomechanics than previous laser refractive techniques has led to a growth in the interest in clinical and experimental research in this field. This hypothesis is based on the fact that corneal layers with greater stiffness are preserved with this new technique. However, this hypothesis is controversial because clinical research has shown a great disparity in the outcomes.

Comparing surgically induced astigmatism calculated by means of simulated keratometry versus total corneal refractive power.

Purpose: To evaluate surgically induced astigmatism as computed by means of either simulated keratometry (K) or total corneal refractive power (TCRP) after temporal incisions.

Methods: Prospective observational study including 36 right eyes undergoing cataract surgery. Astigmatism was measured preoperatively during the 3-month follow-up period using Pentacam.
