Methods: Retrospective chart review of residentperformed phacoemulsification cases at the Atlanta Veterans Affairs Medical Center, Decatur, Georgia, from July 1, 1999, through June 30, 2002. Outcomes measured included postoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), intraoperative complications, and adjusted phacoemulsification times (total phacoem...
this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...
Resonant structure is one of the proposed methods in combining power in RF systems of RF accelerators. In this structure, fabrication of RF power divider or combiner using coaxial and cylindrical cavity is important. In this study, two combiners, in the same frequency band, are designed and fabricated; and their results are compared. The experimental results confirmed the simulation results an...
PURPOSE To evaluate the incidence and severity pattern of dry eye after phacoemulsification. SETTING King Chulalongkorn Memorial Hospital, Bangkok, Thailand. DESIGN Prospective descriptive study. METHODS Samples were collected from ninety-two uncomplicated cataract patients who were 18 years old or older. Dry eye incidence and pattern were analyzed at days 0, 7, 30 and 90 after phacoemuls...
recently, small incision cataract extraction by phaco and implantation of a foldable intraocular lense with topical anesthesia has used in an attempt to decrease the complication of general anesthesia and peribulbar injection. to compare effects and complications of topical, local and general anesthesia, 92 patients admitted to imam hosein hospital for cataract surgery, were randomly assigned t...
This paper presents a calibration technique for a coaxial sensor using a transmission signal approach. The sensor was fabricated from commercially available RG402/U and RG405/U semi-rigid coaxial cable. The length of the coaxial sensor was correlated with the attenuation and standing wave inside the coaxial line. The functions of multiple reflection amplitude and tolerance length with respect t...
Introduction: The objective of this study is to determine whether there a relationship between intraocular pressure (IOP), diabetes mellitus, and hypertension with visual acuity in senile cataract patients after phacoemulsification surgery. Methods: A retrospective cross-sectional who underwent surgery from 2019-2020 at Christian University Indonesia General Hospital. Data were taken medical re...
Bimanual microincision phacoemulsification entails the removal of the crystalline lens through 2 1.2 mm incisions. Infusion is provided through a separate irrigating handpiece, and phacoemulsification and aspiration are performed through a sleeveless phacoemulsification needle. We describe a technique for refractive lens exchange using bimanual microincision phacoemulsification. Capsulorhexis f...
