The gap between a recently developed dynamical version of relaxed magnetohydrodynamics (RxMHD) and ideal MHD (IMHD) is bridged by approximating the zero-resistivity "Ideal" Ohm's Law (IOL) constraint using an augmented Lagrangian method borrowed from optimization theory. augmentation combines pointwise vector Lagrange multiplier global penalty function can be used either for iterative enforceme...
PURPOSE To evaluate the clinical efficacy and complications of intraocular lens (IOL) exchange. METHODS A review of medical records was performed for 52 eyes that had undergone an IOL exchange due to IOL opacification. Surgical complications and their incidences were analyzed. The mean best corrected visual acuity (BCVA) after the IOL exchange was compared with the mean pre-exchange BCVA and ...
PURPOSE To evaluate the effect of refractive surgery on intraocular lens (IOL) power calculation, compare methods of IOL power calculation after refractive surgery, evaluate the effect of pre-refractive surgery refractive error on IOL deviation, review the literature on determining IOL power after refractive surgery, and introduce a formula for IOL calculation for use after refractive surgery f...
Objective: To report opacification of hydrophilic acrylic and silicone foldable intraocular lenses (IOL). Designs: Case series. Participants: Five patients with IOL opacification. Results: We report five eyes of five patients with late opacification of the intraocular lens (IOL). Three patients had hydrophilic acrylic (SC60B-OUV-MDR, Inc), two had silicone IOL (Allergan SI30NB). Two out of the ...
Endothelial distance after phakic iris-fixated intraocular lens implantation: a new safety reference
PURPOSE To evaluate the distance between the endothelial surface of the cornea to the anterior edge of an Artiflex® phakic intraocular lens (IOL) implant to improve the safety profile of this implant. METHODS This is a retrospective clinical case series of 45 patients who had Artiflex phakic IOL implantation (Artiflex p-IOL) with a follow-up period of 3 years. A Pentacam HR imaging system was...
PURPOSE To evaluate the indications, lens styles, perioperative findings, and results of intraocular lens (IOL) explantation or exchange performed in the authors department in 2005. METHODS The retrospective analysis comprised 22 patients (23 eyes). Twenty-one eyes had previous phacoemulsification and IOL implantation, one eye secondary aphakic IOL, and one eye phakic IOL implantation. The in...
OBJECTIVE The objectives of this review were to identify the predictive factors of induction of labor (IOL) failure or success as well as to highlight the current heterogeneity regarding the definition and diagnosis of failed IOL. MATERIALS AND METHODS Only studies in which the main or secondary outcome was failed IOL, defined as not entering the active phase of labor after 24 h of prostaglan...
هدف: مقایسه نتایج کارگذاری لنز داخل چشمی (IOL) در فضای کپسولی با کارگذاری هاپتیک لنز در فضای شیار سیلیاری و گیر انداختن (capture) اپتیک در کپسول خلفی در جراحی آبمروارید کودکان. روش پژوهش: هجده چشم از 9 کودک دچار آبمروارید مادرزادی دوطرفه در محدوده سنی 8-5/2 سال مورد مطالعه قرار گرفتند. چشمهای هر بیمار به طور تصادفی در یکی از گروهها قرار گرفت. در یک چشم (گروه کپسولی) پس از انجام کپسولورک...
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...
