PURPOSE To determine the efficacy, predictability, safety, and short term stability of laser in situ keratomileusis (LASIK) in treating patients with low myopia and astigmatism using the Chiron Technolas Keracor 117 PlanoScan excimer laser. METHODS We retrospectively studied the results of our initial 83 eyes with myopia ranging from -1.13 to -7.25 diopters (D) and astigmatism of no more than...

AIMS To examine prospectively the recovery of various parameters after discontinuation of overnight orthokeratology. METHODS Seventeen subjects undergoing orthokeratology for 12 months were examined. Refraction, corneal topography, wavefront aberrometry, a visual acuity test and a contrast sensitivity test were performed at baseline, 12 months after commencement of the procedure, and 1 week a...

PURPOSE To describe a case of cystoid macular edema (CME) developing after posterior chamber toric phakic intraocular lens (PIOL) implantation. METHODS Case report. RESULTS A 33-year-old male underwent implantation of toric implantable collamer lenses (ICL), a new generation of PIOLs, for both eyes. Preoperative best spectacle-corrected distance visual acuity (BCVA) was 20/25 in the right e...

The refractive result is a criterion for the quality of surgical correction cataract. aim this study was to analyze results obtained in calculating optical power intraocular lens (IOL), by applying formulas Holladay II and Barrett Universal II, treatment patients. conducted over period 2 years analyzed 235 eyes 160 patients (80 women 80 men) who underwent surgery at MMA Eye Clinic (Sofia) betwe...

purpose: to determine the prevalence of uncorrected refractive errors and its determinants in tehran in 2002. methods: a total of 6497 citizens representing a cross-section of the population of tehran were sampled using a stratified random cluster sampling strategy. of these, 4565 (70.3%) subjects participated in the study and were transferred to a clinic for an extensive eye examination and in...

PURPOSE To investigate the association of hyperopia greater than +3.25 diopters (D) with amblyopia, strabismus, anisometropia, astigmatism, and reduced stereoacuity in preschoolers. METHODS Three- to five-year-old Head Start preschoolers (N = 4040) underwent vision examination including monocular visual acuity (VA), cover testing, and cycloplegic refraction during the Vision in Preschoolers S...

PURPOSE To study, for the first time, the effect of wearing ready-made glasses and glasses with power determined by self-refraction on children's quality of life. METHODS This is a randomized, double-masked non-inferiority trial. Children in grades 7 and 8 (age 12-15 years) in nine Chinese secondary schools, with presenting visual acuity (VA) ≤6/12 improved with refraction to ≥6/7.5 bilateral...

BACKGROUND Scleral cross-linking (CXL) is a novel attempt to slow down the axial elongation process in animal eyes. As a natural CXL reagent, genipin would be also effective for the prevention of myopia process. Thus, the present study was designed to evaluate the effects of scleral cross-linking using genipin on the form-deprivation (FD) myopia process of guinea pigs. METHODS Twenty-seven 3-...
