OBJECTIVE To evaluate the aberration and visual quality differences between myopic and astigmatic eyes before and after contact lens application by using corneal aberrometer and low- contrast sensitivity chart. METHODS Eighty eyes of 40 patients were included in this study. Patients were divided into two groups as myopic (40 eyes, n=20) and astigmatic groups (40 eyes, n=20). We used aspheric ...

PURPOSE To analyze the corneal endothelial cell density in healthy adult emmetropic subjects. METHODS We analyzed the corneal endothelial cell density of a group made up of 225 emmetropic subjects (n=225). As age-matched control groups we analyzed two other groups, one made up of myopic subjects (n=209) and the other made up of hyperopic subjects (n=203). We recorded the mean of three consecu...

Myopic choroidal neovascularization (CNV) is a sight-threatening condition which occurs in eyes with myopia, particularly in those with pathologic myopia. It is the most common cause of CNV among patients younger than 50 years. Hemorrhage and exudation from the CNV lesion may eventually result in scarring or chorioretinal atrophy. While myopic CNV was previously treated with focal laser photoco...

In this paper, we consider the problem of pollution control in a system that undergoes regular regime shifts. We first show optimal policy abatement is periodic and described by unique hybrid limit cycle. next introduce notion an environmentally-sustainable solution, demonstrate only one yields best possible trade-off between steadily achieving profit preserving environment. contrast, not event...

AIMS To determine the surgical outcome of indocyanine green (ICG) assisted retinal internal limiting membrane (ILM) peeling in macular hole surgery for severely myopic eyes and compare the visual and anatomical outcomes with an emmetropic control group. METHODS 10 severely myopic eyes (-6.0 D or greater) of 10 patients with macular holes without retinal detachment were recruited prospectively...

PURPOSE We compared the retinal thickness (RT) and choroidal thickness (ChT) between the fellow eyes of nonamblyopic myopic anisometropes. METHODS The eyes of 22 nonamblyopic myopic anisometropes (≥ 1 diopter [D] spherical equivalent refraction [SER] anisometropia) were examined using spectral domain optical coherence tomography (SD-OCT). Customized software was used to register, align, and a...

Objective To determine the relationship between the preoperative axial length and the myopic shift over 3 years after congenital cataract surgery with primary intraocular lens implantation and other related factors. Methods In this retrospective cohort study, the axial length was measured and assigned into 2 groups (>21.5 mm and ≤21.5 mm), visual axis obscuration, laterality of cataract, age ...

PURPOSE To evaluate reconstructive foveal anatomical change in surgically closed macular hole (MH) by pars plana vitrectomy with inverted internal limiting membrane flap technique. METHODS Spectral domain optical coherence tomography was used to evaluate foveal microstructures in 20 eyes of 19 patients who underwent pars plana vitrectomy with inverted internal limiting membrane flap technique...
