OBJECTIVES: To evaluate the clinical findings and results of new modified manual deep anterior lamellar keratoplasty (M-DALK) technique compared with a big-bubble DALK (BB-DALK) technique in eyes with corneal scars or lesions. METHODS: A prospective, nonrandomized, comparative study included 65 eyes of 65 patients treated by M-DALK using the blunt scissors lamellar dissection technique or standard BB-DALK. Visual acuity, endothelial cell density, corneal cylinder (Cyl), central corneal thickness (CCT), residual stromal thickness and aberrometric values were recorded pre-treatment and 1, 3, 6, 12 and 18 months after treatment...

OBJECTIVE: To analyze the changes in corneal biomechanical parameters of keratoconic eyes with and without intracorneal ring segment (ICRS) implants after 1 year of corneoscleral contact lens (CScL) wear. METHODS: Seventy-four eyes of 74 patients were divided into three groups: healthy subjects (29 eyes, control group), and 2 groups of subjects with keratoconic eyes (one group of 20 eyes with ICRS implants and one of 25 eyes without them), which were fitted with CScL...

PURPOSE: This study assessed microbiome adherent to contact lenses and defined the bacterial communities associated with use of lens care solutions. METHODS: Among 84 lenses screened for adherent ocular surface bacterial microbiome using 16S rRNA molecular amplification, 63 (75%) generated bacterial-specific amplicons processed using the Ion Torrent Personal Genome Machine workflow. Data were stratified by solution use (peroxide vs. polyhexamethylene biguanide [PHMB]-preserved multipurpose solution [MPS])...

OBJECTIVES: To evaluate the longitudinal tomographic changes and to compare the discriminatory potential of a novel progression display between progressive and nonprogressive keratoconic eyes. METHODS: Retrospective evaluation was made of 81 eyes of 81 patients with keratoconus who had undergone Scheimpflug measurements at least twice with an interval of 12 months or longer between each measurement. The progressive group was defined as 36 eyes, which showed progression according to the definition of the global consensus on keratoconus and ectatic diseases when 2 of the 3 criteria were met, and the other 45 eyes were considered the nonprogressive group...

PURPOSE: To help clinicians diagnose and manage unilateral recalcitrant chronic bacterial conjunctivitis secondary to a retained soft contact lens and describe the first report of Gram-negative bacteria causing this condition. METHODS: Chart review of successive cases presenting with unilateral chronic conjunctivitis with positive cultures and a retained contact lens. RESULTS: Three cases were identified and described. Culturing of the retained contact lenses grew Pseudomonas aeruginosa in the first case, Achromobacter xylosoxidans in the second, and Staphylococcus epidermidis in the third...

PURPOSE: To investigate clinical features and treatment outcomes of pingueculitis with morphological assessments using anterior segment optical coherence tomography (AS-OCT). METHODS: In this retrospective observational study, we examined 22 eyes of 22 patients with pingueculitis. All patients were treated with the same 2-week course of prednisolone acetate 1% drops four times per day. The clinical parameters evaluated were surface dimensions determined by slitlamp biomicroscopy, cross-sectional dimensions determined by AS-OCT, and symptom scores determined by patient surveys...

OBJECTIVES: This report aimed to explore whether certain inflammatory mediators were absorbed, extracted, or bound by various contact lens materials. METHODS: Comfilcon A, balafilcon A, omafilcon A, and etafilcon A were soaked in 500 and 100 pg/mL of interleukin-8 (IL-8), matrix metalloproteinase-9 (MMP-9), or interleukin-1 receptor antagonist (IL-1Ra), and also in combined solutions of inflammatory mediators (500 pg/mL or 100 pg/mL) separately. Lenses were then extracted in 1:1 2% trifluoroacetic acid:acetonitrile...

OBJECTIVES: The aim of this study was to investigate the expression levels of miR-126-3p, miR-182-5p, miR-183-5p, miR-184, miR-221-3p, and miR-205-5p in primary pterygium tissue and compare these levels with those in healthy conjunctiva tissue. METHODS: Twenty-four patients who were diagnosed with grade 3 primary pterygium and scheduled for surgery between January 2014 and January 2016 and had no systemic disease or other ocular pathology were included in the study...

PURPOSE: To evaluate the impact of soft contact lens (CL) wear on the morphology and function of the meibomian glands (MG). METHODS: One hundred seventy-three eyes of 87 soft CL wearers and 103 eyes of 55 age-matched healthy volunteers were included into this study. The patients were divided into 3 groups according to the total duration of lens wear: less than 3 years, 3 to 7 years, and more than 7 years. Ocular Surface Disease Index (OSDI) scores, slitlamp biomicroscopy findings, fluorescein staining of the ocular surface, tear film break-up time (BUT), Schirmer I test, and meibography findings were recorded in all patient eyes and were compared with controls...

OBJECTIVE: To assess two prototype contact lenses (CLs) that extend depth of focus through deliberate manipulation of multiple spherical aberration terms (extended depth-of-focus [EDOF]) for visual performance, accommodative and binocular function, and objective static near refraction against a single-vision (SV) CL. METHOD: This was a prospective, randomized, cross-over, single-masked (participant) clinical trial in which 16 myopic children wore 2 prototype CLs (EDOFL/EDOFH) designed for presbyopes and a SV CL, each for one week...

PURPOSE: To evaluate the prevalence and risk factors of symptomatic dry eye disease (DED) among medical students. METHODS: This cross-sectional study included 209 students at a medical school in Korea. Dry eye symptoms were assessed using a 9-item questionnaire, and DED was defined as having one or more dry eye symptoms often or all the time.

OBJECTIVES: To compare the effect of toric versus spherical soft contact lenses on objective measures of visual performance using visual acuity and electromyography of the orbicularis oculi muscle. METHODS: Current soft contact lens wearers with -0.75 to -1.75 D astigmatism in each eye were binocularly fitted with toric (1-Day ACUVUE MOIST for astigmatism) and spherical (1-Day ACUVUE MOIST) contact lenses in random order. After each fitting and at 1-week follow-up, high- and low-contrast visual acuities were measured...

OBJECTIVES: This study aims to determine the diagnostic ability of Pentacam indices for keratoconus and identifying the best index for differentiating diseased from normal cases. METHOD: In this study, 150 keratoconus patients and 150 refractive surgery candidates with a definitive diagnosis of normal healthy corneas were enrolled. Initially, the placido disk topography imaging was performed. The keratoconus and normal corneas were defined based on placido disk topographic data from Rabinowitz-McDonnell...

OBJECTIVES: To evaluate the repeatability of anterior chamber depth (ACD) measurements by Orbscan and Pentacam imaging devices in different grades of keratoconus. METHODS: One examiner performed 3 consecutive ACD measurements with both devices on 74 eyes of 42 keratoconus patient. Repeatability was assessed using intrasession test-retest variability. Within-subject SD was determined for repeatability, and the coefficient of variation was calculated for each measurement...

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...

This study is a retrospectively recruited case series. We report three infants with acute conjunctivitis induced by β-lactamase-positive, ampicillin/clavulanic acid-resistant strains of Haemophilus influenzae (BLPACR). Patients with BLPACR-positive cultures were recruited from among 5,107 patients with inflammatory diseases of the ocular surface who underwent examinations, including bacterial culturing of conjunctival sac or corneal scrapings, between 2000 and 2015. Three BLPACR-positive patients were recruited, including a 10-month-old boy, a 4-month-old girl, and a 7-month-old girl...
