The Utility of Preoperative Phenylephrine Testing in Müller Muscle Conjunctival Resection Surgery for Involutional Ptosis.

Purpose: Phenylephrine testing prior to Müller muscle conjunctival resection has traditionally been used to predict postoperative outcomes. The purpose of this study is to determine if preoperative phenylephrine testing impacts postoperative changes in eyelid position.

Methods: In this multicenter cross-sectional cohort study, 270 eyelids of participants with involutional ptosis and levator function >12 mm who underwent Müller muscle conjunctival resection were divided into 2 comparison groups.

Management of Graves' upper eyelid retraction (GUER): A review.

Graves' disease, a common autoimmune disorder, characteristically presents with upper eyelid retraction, causing significant functional and cosmetic concerns for affected individuals. The management of Graves' upper eyelid retraction has evolved significantly over recent years, with various surgical and non-surgical interventions. An ideal procedure is predictable and easily repeatable.

Effect of Monofocal, Wavefront-Shaped, and Diffractive Trifocal Intraocular Lenses on Scanning-Slit Automated Refraction.

Purpose: To compare scanning-slit retinoscopy automated refraction spherical equivalent (ARSE) to subjective manifest refraction spherical equivalent (MRSE) in normal eyes with four different types of intraocular lenses (IOLs).

Design: Retrospective cross-sectional study.

Methods: A total of 279 pseudophakic eyes that underwent lens extraction at a private center with implantation of either a wavefront shaped IOL (Acrysof® Vivity, DFT015), a nonapodized diffractive trifocal IOL (Acrysof® Panoptix), or a monofocal IOL with negative spherical aberration (Tecnis ZCBOO) or aberration-free (Envista Mx60E).
