Assessment of Central Corneal Thickness in Different Subtypes of Systemic Sclerosis.

Purpose: To compare central corneal thickness between patients with diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis.

Methods: A total of 53 consecutive patients with systemic sclerosis were enrolled in this study. All subjects were screened for age, gender, classification of disease subtype, autoantibody profile, duration of disease, organ involvement, current treatment, tear break-up time, Schirmer test, and measurement of the central corneal thickness with an ultrasonic pachymeter.

Corneal involvement in systemic inflammatory diseases.

Corneal involvement in patients with systemic inflammatory disorders may be sight threatening, and it may be associated with a life-threatening disease. Significant systemic inflammatory diseases in this context are autoimmune connective tissue diseases, systemic autoimmune dermatological disorders, and autoimmune diseases of the lacrimal system. Keratoconjunctivitis sicca is usually the most common ocular finding in these patients.

The accuracy of Goldmann applanation tonometry over silicone hydrogel contact lenses in patients with glaucoma.

Purpose: To investigate the accuracy of measuring intraocular pressure over a silicone hydrogel contact lens using Goldmann applanation tonometry in eyes with glaucoma.

Methods: This was a prospective, randomized study and enrolled 28 patients (28 right eyes) with primary open angle glaucoma. Intraocular pressure was taken with and without a silicone hydrogel contact lens (-0.

Very late-onset corneal scar triggered by trauma after photorefractive keratectomy.

A 54-year-old woman who had photorefractive keratectomy (PRK) more than 10 years earlier presented with a history of being hit in the eye by a tree branch and developing blurred vision a short time later. The corrected visual acuity was 20/100 with localized grade 3 stromal haze. The haze intensified despite initial response to corticosteroids and cyclosporine, and treatment with phototherapeutic keratectomy and 0.

Evaluation of dry eye signs and symptoms in patients with systemic sclerosis.

Background: One of the most frequent ocular features of systemic sclerosis (SSc) is dry eye disease (DED), which has been identified to occur in 37-79% of patients. Although several studies have found weak or no correlations between symptoms and signs of dry eye, symptoms are often the motivation for seeking eye care, and are therefore a critical outcome measure when assessing treatment effect. The aim of this study is to evaluate the impact of symptoms of dry eye on vision-related quality of life in patients with systemic sclerosis, and to investigate the relation between clinical tests and symptoms of dry eye in these patients.

Effects of blue light-filtering intraocular lenses on the macula, contrast sensitivity, and color vision after a long-term follow-up.

Purpose: To evaluate the possible side effects and potential protection 5 years after implantation of an intraocular lens (IOL) with a blue-light filter (yellow tinted).

Setting: Ophthalmology Department, University of São Paulo, São Paulo, Brazil.

Design: Prospective randomized clinical study.

Optical quality in eyes implanted with aspheric and spherical intraocular lenses assessed by NIDEK OPD-Scan: a randomized, bilateral, clinical trial.

Purpose: To determine whether implantation of an intraocular lens (IOL) with an aspheric surface (Akreos AO, Bausch & Lomb Inc) results in reduced ocular aberrations (spherical aberration) and improved Strehl ratio and modulation transfer function (MTF) after cataract surgery.

Methods: In an intraindividual, randomized, double-masked, prospective study of 50 eyes (25 patients) with bilateral cataract, an IOL with modified anterior and posterior surfaces (Akreos AO) was implanted in one eye and a biconvex IOL with spherical surfaces (Akreos Fit, Bausch & Lomb Inc) implanted in the fellow eye. Ocular aberrations, Strehl ratio, and MTF curve with 4.

Wavefront analysis and modulation transfer function of three multifocal intraocular lenses.

Purpose: To evaluate wavefront performance and modulation transfer function (MTF) in the human eye after the implantation of diffractive or refractive multifocal intraocular lenses (IOLs).

Materials And Methods: This was a prospective, interventional, comparative, nonrandomized clinical study. Uncorrected distance and near visual acuity, and wavefront analysis including MTF curves (iTrace aberrometer, Tracey Technologies, Houston, TX, USA) were measured in 60 patients after bilateral IOL implantation with 6 months of follow-up.

Wavefront analysis, contrast sensitivity, and depth of focus after cataract surgery with aspherical intraocular lens implantation.

Purpose: To determine whether implantation of an aspherical intraocular lens (IOL) results in reduced ocular aberrations and improved contrast sensitivity after cataract surgery without critical reduction of depth of focus.

Design: Double-blinded, randomized, prospective study.

Methods: In an intraindividual study of 25 patients with bilateral cataract, an aspherical IOL (Akreos Advanced Optic [AO]; Bausch & Lomb, Inc.
