Tissue damage at anterior capsule edges after continuous curvilinear capsulorhexis, high-frequency capsulotomy, and erbium:YAG laser capsulotomy.

Purpose: To compare the effect of erbium:YAG laser photocapsulotomy (ELC), continuous curvilinear capsulorhexis (CCC), and high-frequency capsulotomy (HFC) on anterior capsule edges using light microscopy (LM) and transmission electron microscopy (TEM).

Setting: Department of Ophthalmology, Department of Histology and Embryology II, University of Vienna, Vienna, Austria.

Methods: Five anterior capsule membranes were obtained experimentally by ELC, which was performed with the Oertli MicroLaser photoemulsification tip in eyes from 5 human cadavers.

Three-dimensional ultrasound for nuchal translucency thickness measurements: comparison of transabdominal and transvaginal ultrasound.

Objective: We compared nuchal translucency (NT) thickness measurements using two-dimensional (2D) transabdominal, three-dimensional (3D) transabdominal, and 3D transvaginal ultrasound to determine levels of agreement.

Methods: One hundred one pregnant women with a median gestational age of 12.6 weeks (range 11-14 weeks) were included in this study.
