Filter by:Compelling evidence of genetic components in high myopia has been put forward by several studies. Twin cohorts, familial linkage studies and population studies has described at least 10 loci containing genes involved in the disease development. The investigators previously demonstrated novel linkage on chromosome 7q36 and chromosome 7p15 in French families. A new approach consisting of a case-control based population association study is underway in order to recover a high number of myopic subjects avoiding the limitation of familial cases. 1.8 millions polymorphic markers will be compared with emmetropic controls in order to recover loci associated with the disease in the population.
This study aims to determine the treatment effect of accommodative/vergence therapy on myopic children by assessment of accommodative function before and after therapy.
The principle investigator is evaluating self-reported quality of vision and quality of life in physicians undergoing LASIK, SMILE and PRK surgery.
The purpose of this study is to evaluate the thickness accuracy of Laser-assisted in situ keratomileusis (LASIK) flaps created with the LenSx® Laser.
The investigators are comparing outcomes of LASIK surgery using a high definition wavefront-guided laser to a wavefront-optimized laser in patients with nearsightedness with and without astigmatism.
This study is a masked, multi-center, daily wear, monthly replacement, bilateral, randomized, lens blocked (subjects remain in the same lens brand throughout the study) concurrent control study enrolling up to 90 subjects with a study duration of approximately three months. Subjects will be randomized into the study contact lenses in a two to one (2:1) ratio of fanfilcon A lens (test) to enfilcon A lens (control).
This study will investigate performance criteria over one week of daily wear to determine if the Study Test contact lens performs equivalently to the comfilcon A contact lenses in terms of subjective ratings and of visual performance. The study test lens was not the final optical design and the study results were not used for the design validation.
To evaluate the short-term changes in ocular surface measures and tear inflammatory mediators after lenticule extraction (FLEx), laser in situ keratomileusis (LASIK) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) procedures.
The aim is to evaluate the short-term changes in ocular surface measures and tear inflammatory mediators after lenticule extraction (FLEx) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) procedures.
The purpose of this study is to test the hypothesis that myopia progression can be slowed or prevented by low dose Echothiophate Iodide.
