PURPOSE: This study evaluated relationships between meibomian gland loss (MGL) and age, sex, and dry eye. METHODS: Dry eye and MGL of the lower eyelid was evaluated from 112 randomly selected subjects (66 women; mean age 62.8; SD ±15.7; and age range: 19-89 years) from Horst Riede GmbH, Weinheim, Germany. In addition, subjects were grouped into dry eye and non-dry eye by the Ocular Surface Disease Index (OSDI) score, lid-parallel conjunctival folds and non-invasive break-up time...

OBJECTIVES: To compare the lotrafilcon B and comfilcon A silicone hydrogel bandage contact lenses after photorefractive keratectomy (PRK). METHODS: One hundred twenty eyes of 60 patients who underwent PRK were included in this randomized clinical trial study. In the end of the surgery, the lotrafilcon B (Air Optix; Ciba Vision, Duluth, GA) was used in one eye and the comfilcon A (Biofinity; Coopervision, Fairport, NY) was used in the fellow eye randomly. Pain and discomfort were assessed on the first and third day after surgery by visual analogue scale...

OBJECTIVES: To assess the relative clinical success of MiSight contact lenses (CLs) (study group) and distance single-vision (SV) spectacles (control group) in children in terms of adverse events (AEs), discontinuations, and tear film osmolarity over a 2-year period. METHODS: Seventy-four subjects aged 8 to 12 with myopia of -0.75 to -4.00 D and astigmatism less than 1.00 D were randomly assigned to MiSight CLs or SV groups. Subjects were monitored at 6-month intervals over the course of 24 months and advised to report to the clinic immediately should AEs occur...

OBJECTIVES: To investigate the corneal biomechanical properties and anterior segment parameters in patients with obstructive sleep apnea syndrome (OSAS). METHODS: Fifty-four eyes of 54 patients with OSAS and 20 eyes of 20 healthy subjects were included. Patients with mild and moderate OSAS (Respiratory Disturbance Index [RDI] <30) enrolled in group 1, those with severe OSAS (RDI≥30) in group 2 and controls in group 3. Corneal biomechanical properties including corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and corneal-compensated intraocular pressure (IOPcc) were measured with ocular response analyzer...

PURPOSE: To analyze the variation in vertical coma and the rest of ocular aberrations before and after fitting prismatic soft contact lenses (PSCL). METHODS: Thirty-seven eyes of 20 healthy subjects (24.30±2.03 years) were evaluated to analyze the variation in ocular wavefront aberrations before and after fitting PSCL of different base-down prism values (1.0, 1.5, and 2.0 prism diopters [PD]), designed to study its influence in the compensation of vertical coma aberration...

OBJECTIVES: To compare the changes in the corneal endothelial cells of both the patients with keratoconus who use rigid gas-permeable (RGP) contact lens and who do not use any contact lens with healthy population. METHODS: Thirty-three patients with keratoconus who use RGP contact lenses (group 1), 20 patients with keratoconus who do not use any contact lens (group 2), and 40 healthy controls were included in the study. Changes in the corneal endothelial cells of all patients were evaluated using a noncontact specular microscope...

PURPOSE: To analyze the state of scientific publications in the field of scleral lenses applying a bibliometric study. METHODS: The database used in this bibliometric study was SCOPUS, the largest abstract and citation database of peer-reviewed literature: scientific journals, books, and conference proceedings. Using remote download techniques, articles published between 1962 (year of first registrations) and 2015 were selected by entering the main descriptors: "scleral contact lenses" and "scleral lenses," limiting the field for the article, keywords, and abstract, linked with the OR tab...

OBJECTIVES: To evaluate the interlaboratory and intralaboratory reproducibility of a proposed protocol for multipurpose contact lens solution (MPS) disinfection efficacy against Acanthamoeba. METHODS: Acanthamoeba castellanii and Acanthamoeba polyphaga and four MPS with different biocidal agents were used to evaluate the protocol in two different laboratories. In addition to the negative control, a positive control and neutralization control were used. One experiment was performed in triplicate, and all other experiments were performed in duplicate in each laboratory...

OBJECTIVES: To examine the progression pattern of disc and retinal lesions in highly myopic Chinese adolescents over a 10-year period in Singapore. METHODS: This longitudinal study included Chinese participants who showed high myopia (spherical equivalent [SE] worse than or equal to -5 diopters [D]), no history of refractive surgery, and available fundus photographs at both 2006 (baseline) and 2016 (10-year follow-up) visits. Forty-four adolescents (aged 12-16 years at baseline) who were re-examined later at follow-up were included...

OBJECTIVES: Stenotrophomonas maltophilia is an opportunistic pathogen known to form biofilms on contact lens and case surfaces that may result in permanent visual loss in cases of microbial keratitis. Because of its multiple drug resistance and extremely low incidence, there is little consensus on treatment. We investigated the predisposing factors, management, and visual outcomes in a small case series of patients to better inform the management of this rarely reported keratitis. METHODS: Retrospective analysis of medical records was performed at a single tertiary referral center between 2011 and 2017...

OBJECTIVES: To assess contact lens preservative uptake and release from multipurpose solutions (MPS) and subsequent acquisition of lens antibacterial activity. METHODS: Kinetics of uptake and release of poly (hexamethylene biguanide hydrochloride) (PHMB) or polyquaternium-1 (PQ-1) from various contact lenses were studied initially with the pure compounds and then after soaking in MPS containing these compounds. Lenses soaked in MPS were tested for antibacterial activity...

OBJECTIVES: To quantify tear elimination rate (ER) underneath silicone hydrogel (Si-Hy) and scleral gas permeable (GP) contact lenses (CLs). METHODS: Subjects successfully using either well-fitting soft Si-Hy CLs or scleral GP CLs were recruited. Most scleral GP CL wearers had irregular corneas (e.g., keratoconus). An objective fluorometer measured decay of fluorescein isothiocyanate dextran dye signal (70 kD MW) from which the tear ER in %/min was calculated. For GP scleral lenses, the ER was determined for both the initial settling period and the 30- to 60-min period, and without lenses...

OBJECTIVE: To assess the relationship between sociodemographic variables (including race, age, and insurance coverage) and preoperative best-corrected visual acuity (BCVA) at the time of first-eye cataract surgery. METHODS: Single-center retrospective chart review study at Shiley Eye Institute, University of California, San Diego (UCSD). Medical record data from 600 patients were collected from the appointment immediately preceding cataract surgery, including BCVA in the operated eye converted to the logarithmic minimal angle of resolution (logMAR), insurance coverage, race, sex, age, body mass index, smoking status (including pack years), systemic and ocular comorbidities, and ocular surgical history...

OBJECTIVE: Long-term follow-up of contact lens (CL) wearers leads to better understanding of the factors leading to changes in CL trends. This study is an attempt to ascertain these factors in an emerging market like India. Factors like occupation were analyzed to determine if these contributed to changes in selection of CL materials in this article. METHODS: Occupations were categorized as per the norms of International Standard Classification of Occupations-2008 (International Labor Organization, United Nations organization)...
