Two years after uneventful phacoemulsification with posterior intraocular lens implant in an 84-year-old female patient, the capsular bag and enclosed intraocular lens luxated into the vitreous cavity. A vitrectomy was done to extract the lens and capsule for electron-microscopic examination. We found very few zonular attachments to the capsule, but did note hexagonal structures of unknown sign...

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

We report two cases of postoperative Alcaligenes xylosoxidans endophthalmitis. A 78-year-old woman in good general health developed A. xylosoxidans endophthalmitis one month after an uncomplicated phacoemulsification procedure with posterior chamber intraocular lens. It was performed on her left eye, at another institution. Removal of the intraocular lens and capsule was performed because of re...

purpose: to compare acrysof iq and sensar intraocular lens (iols) in terms of spherical aberration and contrast sensitivity.  methods: thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned for implantation of acrysof iq or sensar iols. three months postoperatively, best-corrected visual acuity (bcva), spherical aberration (with 4 and 6 mm pupil d...

A new and complete methodology of monofocal intraocular lens (IOL) design is presented aiming at isoplanatism, i.e. IOLs that provide the eye with optimized optical quality over a wide field of view (typically in a range of ten degrees). The methodology uses a merit function considering dimensional and biomechanical constraints, and a geometrical optical quality metric that is evaluated simulta...

AIM To prospectively investigate changes in the area of the anterior capsule opening, and intraocular lens (IOL) decentration and tilt after implantation of a hydrogel IOL. METHODS 100 patients underwent implantation of a hydrogel IOL in one eye and an acrylic IOL implantation in the opposite eye. The area of the anterior capsule opening, and the degree of IOL decentration and tilt were measu...
