Transscleral fixation technique may reduce intraoperative IOL placement time
A transscleral fixation technique using a foldable posterior chamber IOL and 25-gauge pars plana vitrectomy may improve anatomic and visual outcomes while minimizing the risk of complications and reducing surgical times, according to a study.“The technique achieves the implantation of a posterior chamber IOL through a small incision in the absence of capsular support, which is applicable to a wide range of patients, whether aphakic, pseudophakic with IOL subluxation or dislocation, and/or dislocated cataract or cataract fragments,” study author Daniel A. Adelberg, MD, told Ocular Surgery News.

Study finds increased blink rate correlates with decreased corneal sensitivity
Classifying tear dysfunction groups is important because there are meaningful differences in corneal sensitivity and blink rate among several subcategories, according to a study.“We wanted to compare the standard method for checking corneal sensitivity, which is with a nylon thread (contact method), to a noncontact method (air jet esthesiometer),” co-author Stephen C. Pflugfelder, MD, a professor and director of the Ocular Surface Center in the Department of Ophthalmology at Baylor College of Medicine in Houston, said.
