PROBLEM Effective tamponade of a Descemet-stripping endothelial keratoplasty graft with a gas bubble requires that there is no route for the bubble to escape into the posterior chamber. SOLUTION Exchange the angle-supported anterior-chamber intraocular lens (IOL) for an iris-enclaved Artisan IOL and position the IOL haptics over the peripheral iridectomy to occlude it to the extent that no ga...

The iris-claw intraocular lens (IOL) was recently approved by the U.S. Food and Drug Administration for the correction of refractive disorders. Previous reports are not uniform regarding its potential to induce inflammatory reaction. We report the case of a young healthy patient who experienced persistent and intolerable iritis after implantation of an iris-claw IOL. The iritis was resolved onl...

AIMS To investigate the adhesion characteristics of several intraocular lenses (IOLs) to the simulated and rabbit lens capsule. METHODS Adhesive force to bovine collagen sheets was measured in water with polymethylmethacrylate (PMMA), three piece silicone, and acrylic foldable IOLs. In rabbit eyes, phacoemulsification and IOL implantation were performed. Three weeks later, adhesion between th...

presbyopia is a major refractive challenge for the coming decades. a variety of surgical procedures like scleral expansion, zonal photorefractive keratectomy, and corneal inlay implantation have been investigated none have yet gained popular acceptance. implantation of intraocular lenses (iols) at the time of cataract surgery or refractive lens exchange provides another opportunity to tackle th...

purpose: to evaluate the clinical manifestations and results of lensectomy in patients with hereditary lens subluxation at labbafinejad medical center, tehran-iran from 1996 t 2003. method: in an interventional case series, records of patients with hereditary lens subluxation who had undergone lensectomy were reviewed. patients with at least 6 months of follow up were included. background disea...

We report 2 patients who had radial keratotomy (RK) to correct myopia. The first patient developed a postoperative hyperopic shift and cataract. Nine years post RK, she had intracapsular cataract extraction and implantation of an Artisan aphakic intraocular lens (IOL). Twenty years post RK, hyperopia and astigmatism progressed to +7.0 -5.75 x 100 with a best corrected visual acuity (BCVA) of 20...

PURPOSE In this study, we examined the stability of the lens-angle supporter (LAS) for accommodation restoration by comparing intraocular lens (IOL) location, after-cataract and ciliary body damage after cataract surgery in rabbits. METHODS Eight rabbits were divided into experimental and control groups of four rabbits each. Phacoemulsification and irrigation and aspiration were performed in ...

PURPOSE To describe a new scleral fixation foldable intraocular lens (IOL): the Ultima. METHODS The novel IOL is a new scleral fixation acrylic hydrophilic foldable lens that offers a 360 degrees sulcus support due to its round geometry. It can be folded and inserted through a 4 mm clear cornea incision. Twenty-five eyes implanted with the Ultima lens were followed for 2 years. RESULTS Twen...

We report a combination of surgical techniques during Descemet-stripping automated endoithelial keratoplasty and intraocular lens (IOL) exchange in patients with pseudophakic bullous keratopathy and angle-supported anterior chamber IOLs. During this procedure, the anterior chamber IOL is exchanged for a posterior chamber iris-claw IOL enclavated to the posterior iris; the anterior chamber is ke...

The case illustrates the use of a light-adjustable intraocular lens (IOL) in a patient who had had refractive surgery and developed blunt trauma with resultant flap damage and traumatic cataract. Consistent with early reports of the light adjustable IOL, which show positive results in non-LASIK eyes, this case suggests that the light-adjustable IOL may have similar benefits in the post-LASIK ey...
