PURPOSE To study the effect of small-incision cataract surgery on the optical aberrations of the cornea. METHODS Corneal topography was measured before and after cataract surgery on 70 eyes of 70 patients. Monofocal foldable IOLs were implanted after phacoemulsification through a clear-cornea, 3.5-mm incision without suture. Corneal aberrations, up to the(More)
PURPOSE Form-deprivation myopia has been induced in many different animal species. Underlying mechanisms are not well understood to date. In the current study the possibility of inducing refractive errors by form deprivation in the mouse (C57 BL/6) was investigated. METHODS Thirty animals underwent a 13- to 20-day monocular form-deprivation period by(More)
PURPOSE To investigate the best location of clear-cornea incision in phacoemulsification, depending on preexisting corneal astigmatism. DESIGN Randomized clinical trial and noncomparative interventional case series. METHODS A total of 574 patients in five stages were assigned to the following incisions: superior or temporal (n = 89), superior (n = 141),(More)
PURPOSE To compare the efficacy and sensory outcome of pharmacologic and optical penalization in the treatment of moderate to mild amblyopia. DESIGN Randomized clinical trial. METHODS In an institutional setting, two- to 10-year-old children with strabismic or anisometropic amblyopia (visual acuity in the amblyopic eye at least 20/60) who were(More)
PURPOSE To examine the agreement and relationship between refractive and corneal astigmatism in a population of pseudophakic eyes. METHODS Patients of age at least 40 years, visual acuity 20/40 or better, and no ocular disease were included (n = 111). Refractive astigmatism was obtained by subjective refraction. Corneal astigmatism was measured by(More)
AIM To compare the efficacy of reoperation and botulinum toxin injection in treating infantile esotropes early after unsatisfactory surgical alignment. METHODS 55 strabismic children who had been unsuccessfully operated for infantile esotropia were randomised to reoperation (28 patients) or botulinum toxin injection (27 patients). The motor outcomes(More)
PURPOSE To determine the long-term results of botulinum therapy in acquired esotropia and to identify predictors of a satisfactory outcome. METHODS Sixty-eight children (age range, 8-64 months) with acquired esotropia were enrolled in a prospective study. Botulinum toxin A was injected in the two medial recti. Motor and sensory statuses were evaluated at(More)
PURPOSE To study the induced refractive change caused by different 2.8-mm corneal incision locations in phacoemulsification. METHODS One hundred ten patients were randomly assigned to nasal or temporal incision or to superior incision, depending on preexisting astigmatism. The authors fulfilled visual acuity, refraction, keratometry, and eye scanner(More)
AIMS Two viable options were compared, reoperation and botulinum toxin injection, in the management of children who need retreatment after surgery for acquired esotropia. METHODS 47 strabismic children previously operated to correct an acquired esotropia were randomised to reoperation or botulinum toxin injection. Reoperation was undertaken in 24 of these(More)
PURPOSE To evaluate, using optical coherence tomography (OCT), the prevalence of epiretinal membranes (ERM) in patients referred for phacoemulsification, and the frequency of new ERM development in the first six months after surgery. METHODS Patients referred by general ophthalmologists for cataract surgery underwent a new, complete ophthalmological(More)
