AIM To assess whether intraocular pressure (IOP) is associated with refractive error or axial length in children. METHODS Of subjects from the Singapore Cohort Study of the Risk Factors for Myopia (SCORM), 636 Chinese children aged 9-11 years from two elementary schools underwent non-contact tonometry, cycloplegic autorefraction, and A-scan biometry during 2001. For analyses, refractive error...

PURPOSE To investigate early changes of retinal function in myopic eyes, patients with various degrees of myopia underwent multifocal electroretinography (multifocal ERG). METHODS Thirty young patients (mean age, 26.1 years) were divided into three groups according to the degree of refractive error: emmetropia/low, medium, and high myopia. All groups were matched by sex and age. All subjects ...

OBJECTIVE To evaluate the effectiveness of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for correcting myopia. METHODS Study selection, data extraction, and quality assessment were performed by two of authors independently. Summary odds ratios and 95% confidence intervals were calculated by DerSimonian & Laird random-effects model and Mantel-Haenszel (fixed-effec...

OBJECTIVE To assess intraocular lens (IOL) power calculations in patients undergoing cataract surgery after excimer laser photorefractive keratectomy (PRK) for myopia. METHODS Four eyes of two patients underwent phacoemulsification with IOL implantation after PRK for myopia. The estimated refractive error that would have been induced had the IOL predicted for emmetropia been implanted was cal...

To assess the one year results of Artiflex Phakic intraocular lens (IOL) implantation in the treatment of high myopia. In this non-random interventional study, myopic patients with spherical equivalent worse than -5.0 diopters (D) who were not eligible for laser surgery were assessed. All patients had refraction, uncorrected and best corrected visual acuity tests (UCVA and BCVA), endothelial ce...

PURPOSE We report the postoperative results of the Artisan Hyperopia phakic intraocular lens (IOL; model 203W; Ophtec, Groningen, The Netherlands). DESIGN Prospective, nonrandomized trial. PARTICIPANTS Twenty-six eyes of 13 self-selected patients with refractive error ranging from +3.00 to +11.00 diopters (D). INTERVENTION Patients with hypermetropia were implanted with the Artisan Hypero...

PURPOSE There is a growing interest in multifocal intraocular lens (IOL) implantation in children because they lose accommodation when a cataract is removed. Many have assumed that very little, if any, eye growth occurs in the second decade of life. Multifocal IOL implantation requires precise biometry to arrive at the correct IOL power for spectacle independence. If the eye grows and the refra...

PURPOSE To clarify whether myopes show poor accommodative response and thus have a larger accommodative lag under natural seeing conditions. METHODS Forty-three adults without other ocular abnormalities were classified into the early-onset myopia (EOM, n=28) and the emmetropia (EMM, n=15) groups. The subjects wore glasses or contact lenses that they habitually used, and accommodative response...

makes it impossible to express the results in a general and informative manner. We felt, therefore, that it was useful to define two index that can be used for the purposes of such analysis. Metho& The axial and toric components of ametropia are such that it can be seen as a point within a threedimensional reference. The distance between the point and the centre of a reference defines the Refra...

Purpose To evaluate the outcomes following bilateral ERV intraocular lens implantation with micromonovision. Methods 25 subjects underwent bilateral Tecnis Symfony IOL implantation with micromonovision. The dominant eye was targeted for emmetropia and the nondominant eye for myopia of -0.75 D. Uncorrected and corrected distance (UDVA, CDVA), intermediate (UIVA, CIVA), and near visual acuity (...
