History of Lens Care Products in Japan: Insights From Advertisements in the Journal of the Japan Contact Lens Society for 65 Years.

This review examines the history of contact lens (CL) care products, particularly focusing on hard contact lenses (HCLs) like those made from polymethyl methacrylate and rigid gas permeable (RGP) materials. Although literature on CL history is extensive, there is limited information on the history of CL care products, especially in Japan. This review uses advertisements from the Journal of the Japan Contact Lens Society from 1959 to 2023 to trace the evolution of these products.

A Case of Sympathetic Ophthalmia After Corneal Perforation.

We report a case of sympathetic ophthalmia that developed in the fellow eye following therapeutic corneal transplantation and amniotic membrane transplantation for corneal perforation caused by corneal ulceration. A 62-year-old man presented with discharge, lacrimation, and decreased visual acuity in the left eye. He was diagnosed with a corneal ulcer and treated with antimicrobial agents, but corneal epithelial erosion persisted, leading to nontraumatic corneal perforation.

Surgical Technique for Oral Mucosa Harvesting in Autologous Cultivated Oral Mucosal Epithelial Cell Transplantation for Ocular Surface Disorders.

Ex vivo cultivated oral mucosal epithelial cell transplantation (COMET) was first introduced in Japan in June 2021. This technique is used to treat limbal stem cell deficiency (LSCD). This article provides a detailed description of one of the most critical steps in COMET, which is the harvesting of oral mucosa, along with accompanying videos.

A Case of Bacterial Keratitis in a Patient Using Orthokeratology and Soft Contact Lenses.

A 63-year-old male with high myopia developed sudden visual loss, eyelid swelling, eye pain, discharge, and tearing in his left eye while wearing soft contact lenses (CLs) during the day and orthokeratology lenses at night. At the initial visit, his corrected visual acuity in the left eye was 20/1000, with a ring-shaped ulcer in the central cornea, corneal infiltration across the entire cornea, and conjunctival hyperemia. was detected from corneal scrapings, and after antibiotic treatment, the ulcer healed with corneal opacity remaining.

Experimental Study on Ocular Surface Protection by Soft Contact Lenses Due to Volcanic Ash Exposure.

: Sudden volcanic eruptions can lead to volcanic ash entering the eyes, causing severe discomfort and complicating evacuation efforts. The specific effects of volcanic ash on ocular tissues, especially when wearing soft contact lenses (SCLs), are not well documented, prompting this experimental investigation. : White rabbits with normal eyes were randomly divided into three groups: (1) a bare eye group: bare eye + volcanic ash exposure + eye washing, (2) an SCL group: SCL-wearing eye + volcanic ash exposure + eye washing, and (3) a control group: eye washing only.
