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...

PURPOSE To characterize the variations in fundus fluorescein angiography (FFA) features in idiopathic macular telangiectasia (IMT) type 2. METHODS Retrospective observational study. The authors included all the patients with IMT type 2 who underwent FFA during the period from January 2004 to December 2005. The main outcome measures were subretinal neovascularization and number and distance of...

Purpose. To report visual performance and quality of life after implantation of a bifocal diffractive multifocal intraocular lens (MIOL) in postmyopic laser in situ keratomileusis (LASIK) patients. Methods. Prospective, observational case series. Patients with prior myopic LASIK who had implantation of Tecnis ZMA00/ZMB00 MIOL (Abbott Medical Optics) at Hong Kong Sanatorium and Hospital were inc...

This paper proposes an algorithm to register OCT fundus images (OFIs) with color fundus photographs (CFPs). This makes it possible to correlate retinal features across the different imaging modalities. Blood vessel ridges are taken as features for registration. A specially defined distance, incorporating information of normal direction of blood vessel ridge pixels, is designed to calculate the ...

PURPOSE The evaluation of the safety, efficacy, and long-term stability of LASIK procedures utilizing novel platform comprising a femtosecond and excimer laser and multiple networked diagnostics. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS In consecutive cases of myopic LASIK procedure with a novel refractive platform (FS200 Femtosecond and EX500 Excimer Laser), 19...

BACKGROUND The purpose of this work is to report our experience using loteprednol 0.5% for routine prophylaxis after photorefractive keratectomy in an academic refractive surgery center. MATERIALS AND METHODS Photorefractive keratectomy was performed on 579 eyes from 316 patients in this retrospective chart review of patients treated postoperatively with either fluorometholone 0.1% (273 eyes)...

AIM To determine the normative values of white-to-white corneal diameter with Orbscan II Topography System and to compare right and left eyes data in the normal young population. METHODS A total of 1001 healthy participants aged 18-45y participated in this observational cross-sectional study. The study population consisted of 616 female and 385 male subjects. The corneal diameter was measured...

Purpose To evaluate visual outcome, reading performance, contrast sensitivity, and patient satisfaction after cataract surgery with implantation of a diffractive trifocal intraocular lens (IOL). Patients and methods A total of 42 eyes (21 patients) underwent cataract surgery with implantation of the trifocal IOL AT LISA tri 839MP. Visual acuity, contrast sensitivity, and patient satisfaction ...
