Direct visualization of aqueous tear secretion from lacrimal gland.

Purpose: To introduce a new method for direct observation of tear secretion from the palpebral lobes of the main lacrimal glands and Wolfring glands using fluorescein dye.

Methods: Twenty-six patients with dry eye and 26 healthy subjects were included in the study. Fluorescein was applied to the conjunctiva overlaying the palpebral lobe of the main lacrimal glands.

Comparison of Two Optical Biometers.

Purpose: To compare a new optical biometer device, Galilei G6 (Ziemer, Port, Switzerland), with the present optical biometer, Lenstar LS 900 (Haag-Streit, Koeniz, Switzerland), for intraocular lens (IOL) power calculation.

Methods: One hundred forty eyes of 140 cataract patients were evaluated with two optical biometers: the Galilei G6 and the Lenstar. The mean keratometry (K), axial length (AL), anterior chamber depth (ACD), crystalline lens thickness (LT), white-to-white (WTW), and IOL powers using the SRK/T, Holladay 1, Hoffer Q, and Haigis formulas were compared.
