Brazilian medicinal plant, we studied on chemical constituents in the aerial parts of Hyptis fasciculate BENTH. (Labiatae), which is a widespread perennial plant through the southern countries of South America. Its dried leaves and stems have been used for treatment of gout, expectorant, and fever. Although a few interesting cytotoxic a-pyrones and lignans have been found in some species of the...

PURPOSE To evaluate the efficacy of treating patients with +3.00 diopters (D) to +6.00 D of hyperopia via laser-assisted in situ keratomileusis (LASIK) with the WaveLight Allegretto 400 and EX500 excimer laser systems. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS This was a retrospective study of patients undergoing LASIK treatments of +3.00 to +6.00 D on two differ...

PURPOSE To evaluate the results of combined aspheric wavefront-guided transepithelial excimer laser photorefractive keratectomy (PRK) and phototherapeutic keratectomy (PTK) to correct aberrations and refractive errors after radial keratotomy (RK) or keratoplasty. SETTING Sekal Rovigo Microsurgery Centre, Rovigo, Italy. METHODS This retrospective noncomparative consecutive case series compri...

PURPOSE To analyze the position of iris-fixated phakic intraocular lenses (pIOLs) using anterior segment optical coherence tomography (AS-OCT) and evaluate the effect of anterior chamber morphometrics on endothelial cell changes. SETTING Department of Ophthalmology, Academic Hospital Maastricht, The Netherlands. METHODS In this cross-sectional study, AS-OCT was used to measure the distances...

Aim of this paper is to compare the visual outcome in supervised PRK and LASIK surgery. Materials and methods used are Retrospective review of cases performed with Technolas 217 Z platform between July 1, 2009 and June 30, 2010. Inclusion criteria were spherical equivalent of -0.50 to -09.50 diopters (D), refractive mean astigmatic error of -3.00 D, intention to provide full distance correction...

Monovision presbyopia interventions exploit the binocular nature of the visual system by independently manipulating the optical properties of the two eyes. It is unclear, however, how individual variations in ocular dominance affect visual function in monovision corrections. Here, we examined the impact of sensory ocular dominance on visual performance in both traditional and modified monovisio...
