One of the most common cause decrease vision in a pseudophakic patient is formation posterior capsular opacification (PCO) which affected by several factors like design implanted intraocular lens (IOL) and material IOL. PCO incidence has been reported to be 20.7% at 2 years & 28.5% 5 years. Decrease because necessitates capsulotomy with neodymium yttrium aluminum garnet (Nd-YAG) laser create sm...

PURPOSE The aim of this study was to evaluate the operational impact of using preloaded intraocular lens (IOL) delivery systems compared with manually loaded IOL delivery processes during routine cataract surgeries. METHODS Time and motion data, staff and surgery schedules, and cost accounting reports were collected across three sites located in the US, France, and Canada. Time and motion dat...

Previous determination of the nucleotide sequence of the iol region of the Bacillus subtilis genome allowed us to predict the structure of the iol operon for myo-inositol catabolism, consisting of 10 iol genes (iolA to iouJ); iolG corresponds to idh, encoding myo-inositol 2-dehydrogenase (Idh). Primer extension analysis suggested that an inositol-inducible promoter for the iol operon (iol promo...

by Dimosthenis Mantopoulos, MD, PhD; Howard F. Fine, MD MHSc; and Jonathan L. Prenner, MD There has been a wave of new and innovative techniques for vitreoretinal surgeons in the management of aphakia as well as subluxed or dislocated intraocular lenses (IOLs). Several of these techniques are quite elegant and fun to perform, but most incur a learning curve to master. Having a number of these o...

PURPOSE To determine whether rotational stability is improved with the longer Staar toric intraocular lens (IOL). SETTING A private practice, Los Altos, California, USA. METHODS Staar Surgical manufactures toric plate-haptic IOLs under +24.0 diopters (D) in 2 lengths. Fifty consecutive eyes requiring toric IOL spherical powers less than +24.0 D received the longer toric IOL (TL; 11.2 mm) us...

BACKGROUND Ocular biometry is important for preoperative assessment in cataract and anterior segment surgery. The purpose of this study was to investigate normative ocular biometric parameters and their associations in an older Chinese population. METHODS This was a cross-sectional observational study. From 2013 to 2014, we recruited inhabitants aged 50 years or older in Guangzhou, China. Amo...

PURPOSE To establish a novel murine intraocular lens (IOL) implantation model to study the protective effects of colored-IOLs against retinal phototoxicity. METHODS Two-millimeter diameter IOL buttons were created from IOLs for clinical use. Extra-capsular crystalline lens extraction and IOL implantation were performed in BALB/c mice using a technique similar to human cataract surgery. For li...
