Article Abstract
Nanoparticle-laden contact lenses are a formidable strategy for ocular drug delivery. However, incorporating nanoparticles to achieve sustained drug release without affecting the contact lenses' properties remains a challenging task. In this work, daily and monthly replacement silicone-hydrogel contact lenses laden with bovine serum albumin/hyaluronic acid (BSA/HA) nanoparticles are presented. These nanoparticle-laden contact lenses enable the sustained release of 5-fluorouracil (5-FU) in mimetic physiological conditions. The nanoparticle-laden contact lenses display properties similar to neat contact lenses, including refractive index, water content, UV/visible transmittance and chemical structure. Noteworthy attributes include the BSA/HA nanoparticles' low polydispersity, negative surface charge and a hydrodynamic size of ~210 nm, as well as the high nanoparticle loading efficiency (~ 30%) of the contact lenses. Thereby, the BSA/HA nanoparticles are a promising strategy for developing nanoparticle-laden contact lenses for therapeutic applications, namely for sustained drug delivery.

A Clinical Evaluation of Lifitegrast Ophthalmic Solution 5% in Symptomatic Contact Lens Wearers.
Clin Ophthalmol
August 2025
Centre for Ocular Research & Education (CORE), School of Optometry & Vision Science, University of Waterloo, Waterloo, ON, Canada.
Purpose: To evaluate the effectiveness of lifitegrast ophthalmic solution 5% in alleviating end-of-day dryness and discomfort in symptomatic contact lens (CL) wearers.
Patients And Methods: This was an open-label study in symptomatic CL wearers with ratings of ≥40 for end-of-day dryness on a visual analog scale (VAS; 0-100 scale; 100 worst). Participants wore their habitual CLs and instilled lifitegrast twice daily for 12 weeks with lenses removed.
Rotational Stability and Subjective Results of Tecnis Eyhance Toric II Intraocular Lens.

Department of Ophthalmology and Visual Sciences, University of British Columbia, Vancouver, BC, Canada.
Purpose: This study aims to evaluate rotational stability and patient-reported outcomes associated with Tecnis Eyhance toric II "monofocal plus" intraocular lens (IOL), particularly in light of a modified haptic design.
Methods: A prospective, interventional study was conducted with patients undergoing routine cataract surgery and Tecnis Eyhance toric II IOL implantation. The inclusion criteria were topographic corneal astigmatism of 0.
Baseline ocular biometrics in children with orthokeratology-induced axial length reduction or elongation.

Purpose: To determine the baseline ocular biometrics in children with axial length reduction after orthokeratology for better myopia control.
Methods: Changes in ocular parameters in 164 subjects who completed one year of Ortho-K treatment were retrospectively reviewed. The subjects were divided into AL reduction (n = 105, ≤ 0 mm/year axial growth) and AL elongation (n = 59, ≥ 0.

Department of Plastic and Cosmetic Surgery, The Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University, Nanjing, Jiangsu, China.
Objective: The aim of this study was to observe and analyze the histologic characteristics and changes of the upper eyelid regarding blepharoptosis induced by wearing contact lens.
Methods: The levator aponeurosis-Müller's muscle complex specimens from 12 people who wear contact lenses were stained with hematoxylin-eosinand, Masson trichrome and antismooth muscle actin antibodies, and then were observed under light microscopy. The upper eyelids from 6 cadaver specimens were used as controls, and were examined with the same histologic techniques.
