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 ametr…

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…

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 ci…

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 vi…

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 ha…

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 impressi…

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…

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 f…

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 ?)…

(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 …

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 …

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…

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 v…

Says "scientific fact" on the landing page. No scientific paper cited.

(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 co…

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!

Sorry, I thought it was public. I updated my profile.

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…

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, …

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…

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…
