PURPOSE The purpose of this study was to retrospectively compare the incidence of intraoperative flap complications, such as partial flaps, donut-shaped flaps, central corneal cuts, and complete caps with the Hansatome and Automated Corneal Shaper (ACS) microkeratomes. METHODS All laser in situ keratomileusis (LASIK) procedures performed by a single surgeon with the Hansatome or Automated Cor...

sensitivity curve for 1° 200 ms. flashes on a white background may be a rather precise indicator of the functioning of the opponent-color system. Thus, although J. T. believed that his right eye was normal, the corresponding spectral sensitivity curve (continuous curve, Fig. 3) lies near the limit of the normal range, indicating that his right eye may have been partially affected by a similar d...

PURPOSE Soft contact lenses have been reported to increase the progression of myopia. The purpose of this study was to determine whether soft contact lenses affect the progression of myopia in children. METHODS Children between the ages of 8 and 11 years with -1.00 to -6.00 D myopia and less than 1.00 D astigmatism were randomly assigned to wear soft contact lenses (n = 247) or spectacles (n ...

Background: Recent evidence points to the use of spectacles alone in the treatment of anisometropic amblyopia. However, the impact of this treatment on the restoration of binocular vision is often not considered. Case Report: Patient M.Z., aged 7 years, showed 3.5D of anisometropia which was coupled with a best corrected visual acuity of 6/38 in the more hyperopic eye (6/6 in the non-amblyopic ...

The wearing of tinted spectacle lenses is considered by some health care workers to be a marker of psychopathology or a hypochondriacal personality type. The purpose of this study was to determine whether there is a relationship between the wearing of tinted spectacle lenses and personality type in physically healthy subjects. The Sixteen Personality Factor Questionnaire 5th Edition, a multidim...

PURPOSE The development of emmetropic refraction is known to be under visual control. Does partial spectacle correction of infants' refractive errors, which has been shown to have beneficial effects in reducing strabismus and amblyopia, impede emmetropization? The purpose of the present study was to perform the first longitudinal controlled trial to investigate this question in human subjects. ...

PURPOSE To compare the clinical outcome of different multifocal intraocular lenses (IOLs) based on information reported in the international literature. METHODS All comparative clinical trials that involved implanting at least one multifocal IOL in patients with cataract or presbyopia were extracted from the literature. Clinical outcomes included uncorrected near visual acuity, uncorrected di...
