Challenging the current treatment of residual postoperative ptosis: safety and efficacy of repeat Müller's muscle conjunctival resection.

Objective: To determine if repeat Müller's muscle conjunctival resection (MMCR) is a viable approach in the treatment of recurrent or residual eyelid ptosis.

Methods: A retrospective review of patients who underwent repeat MMCR was performed using external photos obtained preoperatively, postoperatively, and at last follow-up. The marginal reflex distances (MRD1 and MRD2), brow position (BP), and tarsal platform show (TPS) were evaluated with digital image analysis.

Refractive index and its impact on pseudophakic dysphotopsia.

Purpose: It has been shown that the biggest dissatisfier for uncomplicated cataract surgery patients is pseudophakic dysphotopsia (PD). While edge design of an intraocular lens (IOL) impacts this problem, refractive index is still controversial as to its impact. This retrospective cohort study was designed to determine the role of increasing refractive index in PD.

Porcine lens nuclei as a model for comparison of 3 ultrasound modalities regarding efficiency and chatter.

Purpose: To validate a porcine lens model by comparing density and ultrasound (US) with known human standards using the Infiniti Ozil with Intelligent Phacoemulsification (torsional), Whitestar Signature Micropulse (longitudinal), and Ellips FX (transversal) modalities.

Setting: Department of Ophthalmology and Visual Sciences, John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.
