Intraocular lens-capsular bag imaging with ultrahigh-resolution optical coherence tomography Pseudophakic human autopsy eyes.

Purpose: To compare in vitro ultrahigh-resolution optical coherence tomography (UHR OCT) cross-sectional images of the pseudophakic human autopsy eye with histology to evaluate the potential of this imaging technique for enhanced visualization of the anterior segment, especially the capsular bag, intraocular lens (IOL), and posterior capsule opacification (PCO) formation after cataract surgery.

Setting: Department of Medical Physics and Department of Ophthalmology, University of Vienna, Vienna, Austria, and Department of Oral and Maxillofacial Surgery Institute of Dentistry, University of Turku, Turku, Finland.

Methods: Ultrahigh-resolution OCT images were acquired from 7 pseudophakic human autopsy eyes using 1.

Optical coherence tomography assessment of capsule closure after cataract surgery.

Purpose: To develop a technique for documenting and quantifying capsule bend formation in pseudophakic eyes, evaluate when the anterior and posterior lens capsules become completely apposed to the optic, and determine how soon a capsule bend is created at the optic edge of an intraocular lens (IOL) after cataract surgery.

Setting: Medical University of Vienna, Department of Ophthalmology, Vienna, Austria.

Methods: This prospective study comprised 33 eyes of 33 patients with age-related cataract who were scheduled to have cataract surgery.

Adhesion of soluble fibronectin, vitronectin, and collagen type IV to intraocular lens materials.

Purpose: To evaluate soluble fibronectin, vitronectin, and collagen type IV adhesion to poly(methyl methacrylate) (PMMA), fluorine-surface-modified PMMA, silicone, hydrophobic and hydrophilic acrylate, and hydrogel intraocular lenses (IOLs) and determine whether hydrophobic and hydrophilic acrylate materials have different fibronectin-adhesion properties.

Setting: Department of Medical Biochemistry, University of Oulu, Oulu, Finland.

Methods: One hundred fifty IOLs were incubated for 1 week at 37 degrees C with radioactive-iodine-labeled soluble fibronectin, vitronectin, or collagen type IV.
