Hi, ophthalmologist here :-) The good news is that if there is no underlying pathology (such as keratoconus, which should be sought in case of progressing astigmatism), every ametropia can be corrected with the right glasses and allow a goo

I had the opportunity to taste this berry where I live (French Polynesia) and indeed very surprised by its powerful sweetening effect. It looks like an under-exploited potential to me.

I'm genuinely interested in your testimony. Did you, by any chance, underwent a refraction after cycloplegia (cyclopentolate) anytime in your life? Cyclopentolate suppresses the ciliary spasm and allows to measure the real, residual m

Yes, hyperopia is a very ungrateful condition... The usual situation is patients which had a perfect vision all their life, and, around 40, lose their near vision, and their far vision a few years later. This is always a little bit depressi

There is indeed much more evidence for this advice. This is my I do with my kids. Using your far vision a lot I childhood, with enough light exposure, could be a real preventive habit.

No you can't do that, because the patient must look at a target. There is an eye tracker in the laser but you have to look in the right direction. The surgery is much less impressive that you can imagine. Take an advice with a reputabl

The problem is that you can't measure axial length with an autorefractometer. You need a biometer. The autoref will tell you the objective refraction of the patient (which is quite imprecise). The eyeball gets longer with time in high

Ophthalmologist here. The myopia epidemic is real thing. The advice given in this post is not a dangerous thing to try. However, I doubt that the theory is true, and I doubt that following this method will really help myopic patients. Let&#

Well, by looking at all the answers, I obviously missed my point. Sorry for that :-) (I'm not a native english speaker as you noticed so it may also explain the misunderstanding ?) Of course this is not how I talk to my patients... I u

(Ophthalmologist): To any future HN reader scared by those intraocular injections: don't fear them. I'm on my way to the operating room and going to perform cataract surgery under topical (=eyedrops only) anesthesia, as I always d

Yes, of course. A simple Pubmed query will bring a lot of occurrences : https://pubmed.ncbi.nlm.nih.gov/?term=Keratoconus+eye+rubbin... For a complete argumentation and discussion about the case for the role of eye rubbing

This is infuriating. This is why I always comment when I see people talking about KC on HN (guess what? There is a lot. I won't do the research but I'm almost sure that this is the most frequent pathologie people here talk about.

Hi, I'm an ophthalmologist, corneal specialist (and regular HN reader). I just would like to draw your attention to the absolute necessity to avoid any eye rubbing. This point is very often ignored by some colleagues, for various reaso

(empirical, non scientific opinion): usually, wearing contact lenses tends to prevent vigorous eye rubbing, during the day. Also, people with sensitive, itchy eyes tend to avoid contact lenses: this is a two-way relationship. Nefarious eye

If the outcomes are as great as they look, I think one could expect "mainstream adoption" (specialized centers and unfrequent indications) in 2-3 years ? This is a hard guess!

To start with, full disclosure : this is a controversial topic. The majority of eye surgeons are still convinced that there is a genetic predisposition to keratoconus, and that eye rubbing is an optional trigger. Other (a growing number) th

I sympathize. I don't know what kind of procedure you underwent. If the blurry vision comes form an irregular anterior corneal surface, scleral lenses can be a game-changer. Also, cellular therapy could be an option in a few years, y

Corneal surgeon here ! (Note : I never implanted a keratoprosthesis. This is an extremely unfrequent procedure, usually performed by a handful of surgeons in a given country). Some insights about this topic. This looks like a great device

Thank you, great work.

Haha, nope ! As a convenience procedure, and as such exposed to liability risks, and because of the extremely high cost of the lasers, you'll have to pay 2-3000 euros for both eyes (in France, at least). It is in fact cheaper in the US

Lasers revolutionized medicine, particularly in two specialties where the organ is accessible to light: dermatology and ophthalmology. We use : - excimer laser (UV) for their photoablative properties, to change to anterior corneal radius of

I agree on the very long term possibilities. However, the first problem to solve is the data collection. Saving doctors and nurses from their horrible professional softwares and replacing them with user-friendly, well-thought, data collecti

Honestly, I don't know what to think. Ophthalmology is a great field for AI researchers (lots of images: the eye is an organ that you can photograph and analyze visually in every angles, almost like in dermatology). In Ophthalmology, d

This is exacerbated by the fact that if the AI told the doctor that there is a doubt, no doctor will take the risk of not doing a biopsy / scanner / MRI / surgery (depending on the case). Because, how would you defend yoursel

Hi, I did not intend to be disrespectful, sorry if you read my message like this. I mainly intended to underline the fact that we (doctors) were promised a revolution in healthcare (AKA : to disappear) and we ended with diagnostic scores. H

I assumed that basic ML was similar to the statistics I already knew, and that deep learning was inherently different. It had to be different, given how people talked about it. It is just an illustration of how the fuss made about AI at thi
