🤓 AI-Powered Implant Helps the Blind Read Again
In a European trial led by Moorfields and University College London, surgeons implanted a two-millimeter microchip called PRIMA beneath the retina of people who had completely lost central vision from dry age-related macular degeneration (AMD).
Presented at #AAO2025:
In persons with geographic atrophy due to age-related macular degeneration, a neurostimulation system composed of glasses, a processor, and a subretinal implant restored central vision and significantly improved visual acuity. Full PRIMAvera study:

🧠 How the System Works
The device works with camera glasses and a pocket-sized processor to rebuild a digital bridge between light and sight. The glasses capture the world in front of the wearer and send it to the belt-worn computer. There, AI-powered vision software analyses what it sees — detecting letters, contrast, and edges — and translates that data into infrared light patterns.
Those patterns are projected back into the eye, where the PRIMA chip converts them into electrical signals that stimulate surviving retinal cells. The brain interprets those pulses as visual shapes and text, producing what patients describe as “a new way of seeing.”
👁️ Results From the Trial
The study involved 38 participants across six European centers, including five treated at Moorfields. Before surgery, none could read at all. After the implant was activated, 84% regained the ability to recognize letters or short words, with some reading up to five lines on a standard eye chart.
Very excited that the clinical trial results for our PRIMA retinal prosthesis are published today in the New England Journal of Medicine! This is the first time that patients who are blind due to photoreceptor loss have been able to intuitively see again.

One participant said the moment she spotted her first letter felt “dead exciting” — like learning an entirely new language for the eyes.
⚙️ Why It Matters
Dry AMD, especially its advanced form known as geographic atrophy, currently has no approved treatment. The PRIMA system offers the first realistic path toward restoring functional central vision rather than just slowing decline. Here’s what Neuroscientist had to say about it earlier this year:
The surgery itself takes under two hours and doesn’t require any internal wiring or batteries; the implant is powered optically through the glasses and remains dormant when not in use.
🔮 What’s Next
The PRIMA system was originally developed by Pixium Vision and is now being advanced by Science Corporation. Researchers plan smaller processors, faster AI rendering, and sharper resolution for future versions.

Regulators will be watching long-term safety and real-world performance — but for patients once locked out of books, menus, and crosswords, this tiny chip marks a monumental step toward independence.
🧑💻 Anthropic Unveils Claude Code on the Web
Anthropic just brought Claude Code to the browser, turning what used to be a developer-only tool into something anyone can try. Think of it as a studio for automated coding tasks that runs safely in the cloud.
You open a Code tab, describe what you want—“clean this script,” “add a chart,” “test this workflow”—and Claude does the heavy lifting on Anthropic’s servers. You can queue several jobs, track their progress, and review the results from one simple dashboard.
🧠 Why Non-Coders Should Care
Instead of local installs or terminal commands, everything happens in a secure browser space. That means no setup headaches, no tangled dependencies, and no risk to your own files. It’s built for people who use tech every day but don’t live inside GitHub.
Anthropic has launched Claude Code on the Web, a browser-based interface that allows developers to delegate coding tasks directly to Claude’s cloud environment without opening a terminal.
Still in beta research preview, this feature is ideal for parallel bug fixing, automation,

Claude Code is part automation assistant, part coding coach. You can feed it a CSV and ask for a quick data summary, turn an idea into a working prototype, or generate snippets that automate chores you’d normally outsource to IT. The tool’s AI-driven reasoning helps translate plain English instructions into clean, executable logic, then shows you what it changed line by line.
🛑 Limits and Risks
Claude Code is still in research preview, so expect guardrails. It can’t yet handle full-scale deployments, and anything that touches live systems should be reviewed by a human. Like all coding AIs, it sometimes invents missing functions or leaves gaps that need cleanup. Some users also note potential safety risks.
My notes on Claude Code for web, Anthropic's new asynchronous coding agent - I had preview access over the weekend, it's effectively a sandboxed instance of "claude --dangerously-skip-permissions" running in Anthropic's container

But the early signs are strong: structured task management, clear explanations, and a calm web interface that makes complex automation feel as easy as describing what you want done. For tech-savvy users, that’s a major step toward hands-on AI productivity.
This Week’s Scoop 🍦
🧩 Weekly Challenge: Connect ChatGPT to Your Calendar
Challenge: Link your calendar so ChatGPT can find openings, summarize your week, and draft holds for you.
Here’s what to do:
In ChatGPT, open Settings then Connectors. Choose Google Calendar or Outlook Calendar and select Connect. Approve the read level permissions. You can toggle automatic use in chat anytime.
Ask simple checks: “What are my free windows on Friday afternoon” or “List my next three meetings with locations.” ChatGPT reads events and replies inline.
Try a workflow: “Find a one hour slot next week with no conflicts, draft an agenda called Q4 plan, and create a prep checklist.” If you connected email too, ask it to draft a short invite you can paste into your calendar.
⚠️ Safety tip: Only grant the minimum access you need and disable automatic use if you prefer explicit prompts. You can disconnect connectors in Settings at any time.
