Accommodation may be restored to presbyopic lenses by refilling the lens capsular bag with a soft polymer. After this accommodative lens refilling prevention of capsular opacification is a requirement, since capsular opacification leads to a decreased clarity of the refilled lens. It has been hypothesized that capsular fibrosis causing the capsular opacification results in increased stiffness o...
PURPOSE Successful intraocular lens procedures, that is, implantation of accommodating intraocular lenses (A-IOL), require firm engagement of the IOL haptics to the capsular bag. We evaluated the use of photochemical bonding to engage IOL materials to the capsular bag. METHODS Freshly enucleated eyes of New Zealand rabbits were used in two types of photobonding experiments using Rose Bengal (...
The presence of pseudoexfoliation material on the surface of an intraocular lens (IOL) is a rare finding. We report a series of seven cases with different patterns of pseudoexfoliation material deposition on the posterior chamber IOLs, recognized 2-20 years after cataract surgery. Six patients had an IOL implanted in the capsular bag and one in the ciliary sulcus. Two patients had undergone pos...
A 45-year-old man with retinitis pigmentosa (RP), who had undergone uneventful extracapsular cataract extraction (ECCE) in his right eye eight years previously, and phacoemulsification in his left eye six years previously, had spontaneously dislocated intraocular lenses (IOL) within the capsular bag in both eyes one month apart. We removed the dislocated IOLs, and performed anterior vitrectomy ...
A case of spontaneous reabsorption of a rubella cataract is presented. The morphology of the capsular bag is recorded by Scheimpflug slit image and retroillumination photography.
Management of the subluxed lens in Marfan’s syndrome presents one of the most challenging situations in contemporary lens surgery. Conventional approaches have included intracapsular lens extraction or a pars plana lensectomy with vitrectomy. Once the lens was removed, aphakia was corrected by glasses, contact lenses or an iris or angle supported anterior chamber IOL or a scleral sutured poster...
PURPOSE To evaluate the effect of complete destruction of lens epithelial cells (LECs) in the capsular bag on intraocular lens (IOL) stability. SETTING School of Biological Sciences, University of East Anglia, Norwich, United Kingdom. DESIGN Comparative evaluation. METHODS An in vitro organ culture model using the bag-zonule-ciliary body complex isolated from fellow human donor eyes was p...
megacystis microcolon intestinal hypoperistalsis syndrome (mmihs) is a rare and the most severe form of functional intestinal obstruction in the newborn. the characteristic features of this congenital and fatal disease are abdominal distension, absent or decreased bowel peristalsis. abdominal distension is a consequence of the distended, unobstructed urinary bladder with or without hydronephros...
Transient lower esophageal sphincter relaxations (tLESRs) are vagally mediated in response to gastric cardiac distension. Nine volunteers, eight gastroesophageal reflux disease (GERD) patients, and eight fundoplication patients were studied. Manometry with an assembly that included a barostat bag was done for 1 h with and 1 h without barostat distension to 8 mmHg. Recordings were scored for tLE...
