Phenylephrine, a potent sympathomimetic, induces mydriasis via iris dilator muscle contraction. Intracameral (IC) phenylephrine has been successfully used in cataract surgery for initial mydriasis, maintaining mydriasis, and management of intraoperative floppy iris syndrome. Serious systemic adverse events (mainly cardiovascular) have been described with topical phenylephrine drops, but we found very little evidence of such adverse events associated with IC phenylephrine use. However, we suspect under-reporting of such adverse events, as they may instead be ascribed to anxiety, positioning, anaesthesia, etc...

PURPOSE: To evaluate the glistening in four different models of intraocular lenses (IOL) using optical coherence tomography (OCT) and deep learning (DL). SETTING: XXXX. DESIGN: Cross-sectional study. METHODS: 325 eyes were assessed for the presence and severity of glistening in four IOL models: ReSTOR+3 SN6AD1® (n=41), SN60WF® (n=110), PanOptix TFNT® (n=128) and Vivity DFT015® (n=46). The presence of glistening was analyzed using OCT, identifying the presence of hyperreflective foci (HRF) in the central area of the IOL...

PURPOSE: To evaluate the efficacy of topical pilocarpine HCl 1.25% (Pilo) in treating presbyopia in individuals with or without a history of laser vision correction (laser-assisted in-situ keratomileusis [LASIK] or photorefractive keratectomy [PRK]. SETTING: Multiple clinical sites. DESIGN: Pooled analysis of 2 identically designed prospective, randomized, vehicle-controlled studies (GEMINI 1 and 2). METHODS: Adults aged 40-55 years with presbyopia received once-daily Pilo or vehicle bilaterally for 30 days...

PURPOSE: Assess the performances of four intraocular lenses (IOLs) in various spherical aberration (SA) conditions, using the VAO adaptive optics simulator (Voptica S.L.). SETTING: Cullen Eye Institute, Baylor College of Medicine, Houston, TX. DESIGN: Prospective case series. METHODS: Distance-corrected visual acuities at distance (CDVA), intermediate (DCIVA), and near (DCNVA) were measured in 42 dilated pseudophakic eyes at baseline and with ocular SA ranging from -0...

PURPOSE: To screen the patients with monofocal intraocular lens (IOL) for incidence of unaided 20/40 and J5 for distance and near (pseudoaccommodation) and to find factors for pseudoaccommodation. SETTINGS: University Hospitals Sussex NHS Foundation Trust, UK. DESIGN: Prospective study. METHODS: This was a single-eye study (Clinicaltrials.gov: NCT04011696). At 3-9 months, refraction, uncorrected & best-corrected distance & uncorrected near LogMAR acuity, spherical equivalent (SEQ), mesopic pupil size (PS), total eye spherical (Z40), vertical coma (Z3-1) aberrations, reading speed and smallest print size were assessed...

PURPOSE: To investigate the effect of corneal curvature (K) on the accuracy of 8 IOL formulas in highly myopic eyes.
