OBJECTIVE To develop corneal morphometric models with refractive error in excimer laser surgery. METHOD A prospective-longitudinal study was conducted on 78 patients (151 eyes) using the LASIK surgical technique, and 56 patients (111 eyes) with myopic astigmatism using ESIRIS (Schwind-Germany) equipment with pendulous microkeratome. The results were analyzed using descriptive statistics. A NI...

The purpose of this study was to investigate the relationship between refractive errors and high-order aberrations in infant rhesus monkeys. Specifically, we compared the monochromatic wave aberrations measured with a Shack-Hartman wavefront sensor between normal monkeys and monkeys with vision-induced refractive errors. Shortly after birth, both normal monkeys and treated monkeys reared with o...

OBJECTIVE To evaluate the associations of presbyopia and its correction, particularly monovision optical correction, with vision-targeted health-related quality of life. METHODS The National Eye Institute Refractive Error Quality of Life (NEI-RQL) Instrument was prospectively self-administered by subjects from 6 medical centers in the following age and correction categories: subjects with emm...

During the developmental process of emmetropization evidence shows that visual feedback guides the eye as it approaches a refractive state close to zero, or slightly hyperopic. How this "set-point" is internally defined, in the presence of continuous shifts of the focal plane with different viewing distances and accommodation, remains unclear. Minimizing defocus blur over time should produce si...

Purpose : to evaluate the impact of Optinol treatment on ocular surface state in medical students with various types ametropia. Material and methods . The study involved 3 groups patients: two clinical a control group. first group consisted 34 (68 eyes) mild, moderate or high hyperopia, averagely aged 20.1 ± 0.5 years. second 47 (94 myopia, average 20.6 0.9 was composed 60 (120 eyes), 21.4 1.2 ...
