purpose: to assess the results of combined penetrating keratoplasty and cataract extraction by extracapsular extraction versus phacoemulsification and to compare outcomes and complications. methods: in this interventional retrospective study, 76 eyes that had undergone triple surgery were included. cataract surgery was done in two different methods of extracapsular extraction and phacoemulsific...

Phacoemulsification with an intraocular lens implant is a safe and effective means of correction of visual loss from cataract. The high frequency of this procedure world wide means inevitable direct surgical complications will be numerous even though infrequent. The approach to correcting aphakia following complicated cataract surgery is dependent on multiple factors including the degree to whi...

BACKGROUND Laboratory analysis and optical quality assessment of explanted hydrophilic intraocular lenses (IOLs) with clinically significant opacification after posterior lamellar keratoplasty (DMEK and DSAEK). METHODS Thirteen opacified IOLs after posterior lamellar keratoplasty, 8 after descemet stripping automated endothelial keratoplasty (DSAEK), 3 after descemet membrane endothelial kera...

Sutureless, glueless, scleral fixation of an intraocular lens is a known technique of fixing a lens in the scleral pockets. However, this technique is applied to single-piece and toric lenses instead of 3-piece lenses, allowing the advantage of the use of premium lenses in patients with poor capsular support. Favourable results without complications of pigment dispersion, iris transillumination...

PURPOSE To investigate the presence of calcium (Ca) aggregates influencing biocompatibility and the factors that affect calcium accumulation in explanted intraocular lenses (IOL) and to analyze the Ca distribution in an opacified hydrophilic acrylic lens. METHODS Surface irregularities and aggregates of 13 IOLs were studied with scanning electron microscopy, and their relative concentrations ...

PURPOSE To compare the predicted and actual refractive errors of hydrophilic, one-piece, C-flex 570C (C-flex) intraocular lens (IOL) implantation in simultaneous vitrectomy and lens extraction in various conditions. METHODS One hundred fifty-nine eyes of patients who had lens extraction between March 2004 and September 2005 were enrolled in a retrospective study. Group 1 had lens extraction a...

Cataract surgery has evolved. The goal of the surgeon includes both restoration of vision and refinement of vision. Patients' desire for spectacle independence has driven the market for presbyopia-correcting cataract surgery and development of novel intraocular lens (IOL) designs. The Tecnis(®) Multifocal Intraocular Lens incorporates an aspheric, modified anterior prolate IOL with a diffractiv...

Several intraocular lens (IOL) materials and types are currently available. Polymethyl methacrylate IOLs used to be the gold standard, but the inability of folding limits their use to selected countries and patients. Silicone IOLs were used more in the past because they are less suitable for microincisions. Foldable hydrophobic acrylic is the most popular material, which is also available in ye...

PURPOSE To evaluate the clinical outcomes of intraocular lens (IOL) exchange in patients with an opacified ACRL-C160 intraocular lens (IOL) using an optic-only removal technique. SETTING Department of Ophthalmology, Soonchunhyang University Hospital, Seoul, Korea. METHODS The study comprised eyes with previous phacoemulsification and implantation of a single-piece hydrophilic acrylic IOL in...
