Feasibility of multifocal intra-ocular lens exchange and conversion to the bag-in-the-lens implantation.

Purpose: Our purpose was to evaluate the surgical outcome after intra-ocular lens exchange in patients who presented impairing visual complaints after primary multifocal intra-ocular lens (MIOL) implantation. In particular, the study was undertaken to look at the number of eyes that could be equipped with the bag-in-the-lens (BIL) IOL after MIOL exchange.

Methods: This series consisted of 30 eyes of 21 consecutive patients scheduled for MIOL exchange.

Surgical outcomes of intraocular lens exchange: five-year study.

Purpose: To report the indications, surgical complications, and outcomes of intraocular lens (IOL) exchange procedures performed over 5 years and to correlate the incidence of perioperative anterior vitrectomy in eyes previously treated by neodymium:YAG (Nd:YAG) laser capsulotomy.

Setting: Department of Ophthalmology, Antwerp University Hospital, Edegem, Belgium.

Methods: In this prospective study, all IOL exchange procedures performed between October 2002 and December 2007 were included.

Fasting-based estimates of insulin sensitivity in overweight and obesity: a critical appraisal.

Objective: To identify simple methods to estimate the degree of insulin resistance.

Research Methods And Procedures: The performance of a wide range of fasting-based index estimates of insulin sensitivity was compared by receiver operating characteristic analysis (area under curves and their 95% confidence intervals) against the M value from euglycemic insulin clamp studies collected in the San Antonio (non-Hispanic whites and Hispanic residents of San Antonio, TX) and European Group for the Study of Insulin Resistance (non-diabetic white Europeans) databases (n = 638).

Results: Insulin resistance differed substantially between lean (BMI < 25 kg/m2), overweight or obese (BMI > or = 25 kg/m2), and type 2 diabetic individuals.
