To investigate the efficacy of SCORE Analyzer (Bausch+Lomb TechnoLas, Germany) in detecting forme fruste keratoconus (FFKC) Asian eyes and validate its usefulness as a risk assessment system for post-laser situ keratomileusis (LASIK) keratectasia.We retrospectively evaluated corneal topographies with Orbscan IIz independently tested them through masked investigators. Eyes were classified into 2 groups: (1) The FFKC group included clinically topographically normal definite contralateral eye....
Purpose.: We determined ocular and systemic factors influencing macular thickness measured by spectral-domain optical coherence tomography (SD-OCT) in a population-based sample of healthy eyes. Methods.: recruited 490 Chinese adults, aged 40 to 80 years, from the Singapore Eye Study, survey. All participants underwent comprehensive eye examination standardized interview. The SD-OCT (Cirrus HD-OCT, software version 6.0) was used measure range parameters (central foveal subfield thickness,...
Purpose To identify risk factors for ectasia after laser in situ keratomileusis (LASIK) by comparing the accuracy of Ectasia Risk Score System (ERSS), Screening Corneal Objective (SCORE) Analyzer, and percentage tissue altered (PTA) predicting occurrence ectasia. Setting Multiple centers 8 countries. Design Retrospective case series. Methods Previously unpublished post-LASIK cases were analyzed. Consecutive patients who had LASIK performed at least 5 years previously with no resultant used...
Purpose: To describe the prevalence and risk factors of ocular trauma in an urban Southeast Asian population.Methods: A population-based survey 3,400 (75.6% response rate) adults Indian ethnicity aged 40–80 years residing Singapore was conducted 2007–2009. An age-stratified (10-year age group) random sampling procedure performed to select participants. Ocular defined as any eye injury requiring medical attention history documented using a standardized validated questionnaire comprising seven...
<h3>Purpose</h3> To describe outcomes and complications following Descemet9s stripping automated endothelial keratoplasty (DSAEK) in eyes with pseudophakic bullous keratopathy (BK) while retaining the anterior chamber intraocular lenses (ACIOL). <h3>Methods</h3> We included consecutive patients who underwent DSAEK for BK at a single tertiary centre from 1 January 2008 to April 2010, our prospective cohort (Singapore Corneal Transplant Study). compared BK, which ACIOL (n=18), those alone...
Background To assess the outcomes of laser-assisted in situ keratomileusis (LASIK) performed for treatment myopia terms safety, efficacy and predictability an 18-year clinical audit. Method In this single-centre, prospective, non-randomised study, preoperative postoperative refractions, uncorrected (UCVA), best-corrected Snellen visual acuity (BCVA) complications all eyes undergoing myopic LASIK were recorded. Safety, efficacy, refractive predictability, trends, retreatment rates...
Purpose.: It is known that a person's socioeconomic status (SES; individual-level SES) closely correlated with his or her degree of visual impairment. Whether there an independent relationship between area-level measures SES (e.g., living in lower environment) and impairment unclear. This study describes the associations Methods.: The authors conducted two population-based cross-sectional studies 3280 adult Malays 3400 Indians Singapore. Visual was defined as LogMAR acuity >0.30...
Background: LASIK Xtra is a recently described technique which combines and accelerated corneal cross-linking(CXL) in the same setting. Its long-term outcome Asians with high myopia not well described. Objectives: To compare efficacy, predictability safety of patients myopia. Method: This retrospective study comparing 50 consecutive eyes undergoing for correction and/or myopic astigmatism (-6.63 to -15.50 D manifest spherical equivalent) matched control group alone (-6.00 -12.25 equivalent)....
To investigate the agreement of vertical cup-to-disc ratio (VCDR) measured from Heidelberg Retina Tomograph 3 (HRT-3), high-definition optical coherence tomography (HD-OCT), and clinical grading.A total 933 consecutive subjects underwent optic nerve head imaging with HRT-3 HD-OCT during a single visit. The dimensions disc cup were by slit-lamp examination using an eyepiece graticule. Bland-Altman plots evaluated in VCDR obtained 2 instruments grading.We found significant trend for difference...
To present the technique and outcomes of a modified manual small incision cataract surgery designed for phacoemulsification surgeons who are learning to perform surgery.This was retrospective, single-centred, comparative study. We included all patients underwent visually significant at Singapore National Eye Centre. All surgeries were performed by either senior phaco-trained surgeon (M.A.) had more than 500 or junior (D.C.) around but never any surgery. The main modification this lies in...

Protective eyewear or corneal shields are recommended during cosmetic facial laser treatment.To describe the occurrence of inlay damage following treatment to eyelids and face with an Nd:YAG laser.This observational case report includes a single incident cared for at tertiary care center. A 58-year-old man who had undergone bilateral uncomplicated myopic in situ keratomileusis surgery 2003 implant nondominant left eye 2013 experienced decreased visual acuity (VA) pain after application 2...
