Chinese researchers may have found a way to reverse childhood myopia using nothing but red light, and the clinical results are already reshaping how the world thinks about corrective lenses.
This video breaks down Repeated Low-Level Red Light therapy (RLRL), a three-minute daily treatment developed at the Zhongshan Ophthalmic Center in Guangzhou that reduced eyeball elongation by nearly 70 percent in a randomized clinical trial, with some children's eyes actually shortening. We explain the science of photobiomodulation, how red light boosts blood flow to the sclera to stop the eye from stretching, and why myopia rates have exploded to over 80 percent among Chinese high schoolers.
You'll learn about the Eyerising device now approved in the UK, EU, Japan, and Australia, why it still isn't FDA-approved in the US, the safety concerns that led China to reclassify these devices, and how low-dose atropine eye drops are emerging as a second major treatment. We also cover why the global eyewear industry has little incentive to fund a cure for the condition it profits from. If you or your child wears glasses, this is the future of myopia treatment you need to understand.
Is This the End of Cataract Surgery? New US Trial Begins
Could an eye drop really replace cataract surgery? The first American patients are now enrolled in a US clinical trial of ZOC2017217, an investigational lanosterol-derived eye drop designed to slow, and possibly reverse, age-related cataracts. As a board-certified cataract and refractive surgeon, I break down what this trial can and cannot tell us, the critical number missing from the company's early data, why the original 2015 lanosterol discovery failed replication, and the truth about castor oil "cures" spreading on social media. Plus: 5 things you can do right now to lower your cataract risk.

Cataract surgery is a safe and common procedure that removes a cloudy lens and replaces it with an artificial intraocular lens (IOL) to restore clear vision.
What Cataract Surgery Involves
Cataract surgery is performed when the eye’s natural lens becomes cloudy, impairing vision. The procedure replaces the cloudy lens with a clear artificial lens called an intraocular lens (IOL). Most surgeries are outpatient procedures, and patients remain awake under local anesthesia, often with sedatives to relax. The most common technique is phacoemulsification, where an ultrasonic probe breaks up the lens, which is then removed and replaced with a foldable IOL through a small incision that usually does not require stitches. Less common techniques include manual extracapsular cataract extraction and laser-assisted surgery .
Preparation Before Surgery
Before surgery, your ophthalmologist will:
- Measure your eye to determine the correct IOL power.
- Review medications and advise on any to avoid.
- Prescribe antibiotic or anti-inflammatory eye drops to prevent infection and reduce swelling.
- Advise fasting for several hours before the procedure .
Recovery After Surgery
Recovery occurs in stages:
- First 24–72 hours: The incision begins to heal; vision may be blurry, and the eye may feel scratchy or watery.
- First week: Protective eye shields are recommended during sleep; avoid rubbing the eye, bending over, or heavy lifting.
- 2–6 weeks: Vision gradually stabilizes; most people notice improvement within a few days, but full healing can take up to 4–8 weeks.
- Long-term: Some patients may develop posterior capsular opacification (secondary cataract) months or years later, which can be treated with a simple laser procedure called YAG capsulotomy .
Patients are usually able to resume light activities, reading, and computer work within a few days, while strenuous exercise, swimming, and heavy lifting should be delayed for 2–4 weeks depending on the surgeon’s advice .
Types of Intraocular Lenses (IOLs)
- Monofocal: Focuses at one distance, usually far; reading glasses may still be needed.
- Toric: Corrects astigmatism.
- Multifocal or accommodating: Provides a range of vision (near, intermediate, distance), potentially reducing the need for glasses .
Risks and Complications
Cataract surgery is generally safe, but potential risks include:
- Eye infection or bleeding
- Swelling of the cornea or retina
- Retinal detachment
- Displacement of the IOL
- Glare, halos, or blurred vision
- Secondary cataract (posterior capsular opacification)
- Rarely, vision loss
Most complications are treatable, and serious problems are uncommon in experienced hands.
Benefits
- Sharper, clearer vision
- Reduced glare and improved color perception
- Potentially less dependence on glasses
- Improved ability to perform daily activities safely
Costs
Cataract surgery is often covered by Medicare and private insurance, especially for standard monofocal IOLs. Premium lenses or laser-assisted procedures may incur additional out-of-pocket costs. Average costs in the U.S. range from approximately $1,600 to $3,000 per eye, depending on the facility, lens type, and insurance coverage .
Key Takeaways
Cataract surgery is a highly effective and commonly performed procedure that restores vision by replacing the cloudy lens with an artificial IOL. Recovery is generally quick, with most patients noticing improved vision within days, though full healing may take several weeks. Discussing lens options, timing, and potential risks with your ophthalmologist ensures the best outcomes for your individual needs .
