A British woman developed acanthamoeba keratitis, a rare corneal infection, after washing her face with her contact lenses still in. The infection caused extreme eye pain and vision loss, leading doctors to sew her eyelid shut to promote healing; she may eventually need a corneal transplant. The case underscores the importance of proper contact lens hygiene and avoiding water exposure while lenses are in.
Researchers are testing electromechanical reshaping (EMR) to temporarily soften and reshape the cornea with a mild electric current, potentially offering a cheaper, less invasive alternative to LASIK; early rabbit-eye experiments show improved focusing power with preserved cell viability, and the approach could address myopia and other refractive errors, but it is still experimental and must undergo extensive animal and clinical testing.
Scientists at NUS bioengineered spinach-derived photosynthetic machinery to function in mammalian corneal cells via eye drops, using light to generate anti-inflammatory chemicals and combat oxidative stress in dry eye disease, a condition affecting about 1.5 billion people; the work, published in Cell, explores a novel, plant-based approach to treating dry eye by harnessing light-driven chemistry in eye tissues (still at early model stages).
A 21-year-old wellness coach who settled in a Mexican beach town woke with severe eye pain and light sensitivity, was diagnosed with acanthamoeba keratitis—a rare parasite eating the cornea—likely entering through tap water and contact-lens use; she endured hourly medicated eye drops, stayed in darkness, and turned to TikTok to document her journey, which went viral and drew GoFundMe support while she hopes to recover and possibly avoid surgery, underscoring eye health and lens hygiene.
