PURPOSE Uncorrected refractive error is recognized as the principal cause of visual impairment in school-aged children. Although correction of refractive error is easy, safe, and effective, many children are without the necessary spectacles. Empiric research on barriers to refractive correction remains limited, precluding the formulation of effective remedial actions. The aims of this study wer...

A case is presented of a patient with an unexpected poor visual result and subsequent correction following cataract removal surgery via phacoemulsification and intraocular lens implantation using a toric intraocular lens implant (IOL). The initial operation resulted in an uncorrected vision of 20/100 (0.70 logMAR). Retrospective analysis of the patient’s corneal topography revealed irregular as...

INTRODUCTION Refractive error remains one of the primary causes of visual impairment in children worldwide, and the prevalence of refractive error varies widely. The objective of this study was to determine the prevalence of refractive error and study the possible associated factors inducing refractive error among primary school children of Malay ethnicity in the suburban area of Kota Bharu, Ke...

PURPOSE To evaluate the visual outcomes and fourth-order Zernike spherical aberrations induced with a customized change in corneal asphericity (ΔQ) correction of presbyopia combined with monovision for hyperopic patients. METHODS Consecutive hyperopic patients who underwent presbyopic LASIK between September 2013 and July 2014 were included. For the non-dominant eyes, the aspheric ablation pr...

OBJECTIVE To evaluate the efficacy and safety of laser-assisted in situ keratomileusis (LASIK) in patients with preoperative dry eye. METHODS We divided the 543 eyes that underwent LASIK into the following 3 groups: eyes with definite dry eye (DE group), with probable dry eye (PDE group), and without dry eye (NDE group). We evaluated visual outcome, dry-eye status, and complications. OUTCOM...

OBJECTIVE To compare visual and refractive outcomes between self-refracting spectacles (Adaptive Eyecare, Ltd, Oxford, UK), noncycloplegic autorefraction, and cycloplegic subjective refraction. DESIGN Cross-sectional study. PARTICIPANTS Chinese school-children aged 12 to 17 years. METHODS Children with uncorrected visual acuity ≤ 6/12 in either eye underwent measurement of the logarithm o...

School children are affected by various eye disorders like refractive errors, squint (strabismus), Vitamin A deficiency and eye infections. Eye diseases in childhood are important causes of medical consultation and it affects learning ability, adjustment in school and personality. Most children do not complain of defective vision, as they may not recognize such conditions as a problem. Uncorrec...

PURPOSE To report the 9-12-month outcomes of a novel procedure for reduction of low myopia through epithelium-on photorefractive intrastromal cross-linking (PiXL) with customized control of topographic distribution of ultraviolet (UV)-fluence. METHOD Myopic patients with normal (non-ectatic) corneas underwent the PiXL procedure for reduction of low myopia. PiXL treatments were delivered throu...

PURPOSE To describe LASIK flap amputation as a therapeutic option for patients with atypical refractory flap complications. METHODS Case series and literature review. RESULTS Seven eyes of 6 patients underwent flap amputation for various atypical indications, including non-infectious flap/interface opacity (3 patients), irregular astigmatism on the flap surface (3 patients), and chronic pai...

We report a case of controlled buccal pemphigus vulgaris with compound moderate myopia with astigmatism that was treated with photorefractive keratectomy with mitomycin-C (PRK+MMC) in both eyes. The preoperative manifest refraction was -6.50 sphere and -5.5 -0.75 x 20 in the right eye and left eye, respectively, with a best corrected visual acuity of 10/10 in both eyes. Seven months after surge...
