To the Editor: I commend Munoz et al on their well-designed and well-conducted study on the clinical effect of a combination of multifocal intraocular lenses (MIOL) including the newest rotationally asymmetric MIOL, which appeared in the March 2012 issue of the Journal of Refractive Surgery.1 They found that contrast sensitivity was comparable to that achievable with a monofocal implant and, re...

purpose : contrast sensitivity (cs) evaluation by sv–1000e chart in all spatial frequencies after micro incision cataract surgery (mics) and its comparison between two thin lenses after optical correction in natural and glare conditions methods : in this cross sectional study, 100 eyes having mics with dodick arc phacolaser system were evaluated. 50 thinoptx lenses and 50 acrismart lenses were ...

Osteoid osteoma is a benign primary bone tumor containing a small region of abnormal osteoid with osteoblasts and variable surrounding reactive bone. Osteoid osteoma accounts for approximately 11% of all benign tumors.1 The majority of osteoid osteomas are monofocal with a single nidus. The orthopedic and radiology literature is scattered with several case reports of multicentric osteoid osteom...

Asymmetric c-lenses are the special cases of asymmetric d-lenses (also called delta lenses) whose updates satisfy a universal property which in many applications ensures “least-change”. There has therefore been hope that symmetric c-lenses might characterize those symmetric dlenses which satisfy a similar universal property. This paper begins an analysis of symmetric c-lenses and their relation...

INTRODUCTION Cryptococcus neoformans commonly affects lungs and central nervous system that to in immunocompromised individual. Bony involvement is extremely rare and most common site is vertebrae and usual presentation is monofocal. CASE REPORT We present 18-year-old male with bifocal osteomyelitis of scapula and tibia in immunocompetent male. CONCLUSION Cryptococcal osteomyelitis should b...

PURPOSE To compare visual outcome and manual handling of additional multifocal sulcus-fixated intraocular lenses (IOLs) of different materials and lens concepts. METHODS Visual outcomes after implantation of a monofocal IOL in the capsular bag followed by implantation of a sulcus-fixated multifocal IOL (MIOL) in patients with cataract were assessed. Patients were randomly assigned to receive ...

PURPOSE To measure the longitudinal chromatic aberration in vivo using psychophysical and wavefront-sensing methods in patients with bilateral implantation of monofocal intraocular lenses (IOLs) of similar aspheric design but different materials (hydrophobic Podeye and hydrophilic Poday). SETTING Instituto de Optica, Consejo Superior de Investigaciones Cientificas, Madrid, Spain. DESIGN Pro...

conclusions: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...

PURPOSE Deprivation of oxygen to the ocular surface during contact lens wear has been implicated in the alteration of sensory function. This study investigates whether increasing oxygen availability through discontinuation of contact lens wear or transfer into highly oxygen transmissible (high Dk/t) lenses leads to a change in corneal or conjunctival sensitivity. METHODS Twenty-seven long-ter...
