Comparison of refractive predictability and endothelial cell loss in femtosecond laser-assisted cataract surgery and conventional phaco surgery: prospective randomised trial with 6 months of follow-up.

Objective: Femtosecond laser-assisted cataract surgery (FLACS) decreases the use of energy and provides a more precise capsulorhexis compared with conventional phaco surgery (CPS). The purpose of this study was to examine if the lower energy use in FLACS caused less endothelial cell loss compared with CPS and if there was a difference in refractive predictability between CPS and FLACS.

Methods And Analysis: This was a randomised controlled study of 96 patients with a 6-month follow-up comparing one eye surgery by FLACS and the contralateral eye operated by CPS (divide and conquer technique).

Signet ring cell carcinoma of the eyelid - the monocle tumour.

We report the clinical and histopathological characteristics of two cases of signet ring cell carcinoma of the eye lids, and discuss the histogenesis of this neoplasm. Two 72-year-old Caucasian males both presented with slowly growing tumours of the eyelids. The tumours were excised and specimens were examined using light- and transmission electron microscopic techniques.
