important thing missing

one thing that is missing and it is extremely important is the definition of long-term wear: what do you mean long-term wear and what do each of the effects studies consider long-term wear? wearing the same contact lens for 5 years without ever taking it off? wearing contact lenses for 8 hours per day for 5 years? what?

I looked over this page, and I dont think it warranted anymore wikifying so I removed the tag.CouchSurfer222 (talk) 09:56, 29 March 2012 (UTC)[reply]

claimed summary?

1. "Many of the observed changes appear to be reversible."

Separated up front, but no citation. Is this a summary? "Many" and "appear"? I could also write "Many of the observed changes appear to be IRreversible". Which of the ones are more important? And citation?

2. And this next sencece "However, this significant decrease in corneal sensitivity appears to be reversible." This is a specific case, this cannot be extrapolated to all cases, neither taken into a summary.

I removed the first one. Some appear one way, other another way. We need to be preceise. — Preceding unsigned comment added by 93.159.131.218 (talk) 08:19, 10 October 2013 (UTC)[reply]

Not up-to-date and not neutral

TL;DR: I fear this article is inaccurate/outdated. Because it concerns a health issue, it needs urgent update.

~

The basis for this article is the 1985 Holden studies and this article raises the health issue of corneal hypoxia (quote: most contact lens-induced changes to the cornea are caused by hypoxia).

Over a decade later and over two decades ago, in 1998, Silicone Hydrogel (SiH) contact lenses became available. They provide much greater oxygen transmissibility than the lenses from the 80's. A few quotes from the contact lens article: These materials have extremely high oxygen permeability and silicone-hydrogel lenses almost eliminate hypoxia in patients due to their very high levels of oxygen transmissibility.

However, there is not a single mention of Silicon Hydrogel in this article. The reader is left completely unaware of the fact that the hypoxia issues raised by the article might not necessarily apply to today's SiH contact lenses.

The mechanical, inflammatory and infectious complications still occur with SiH contact lenses.^[1] When that becomes the new focus of this article, it'll be more up-to-date and more neutral, in my opinion.

Workplan

Hi,

I am a medical student contributing to this article. Reading through the article and this talk page, I noticed that this article was written from a neutral position and the sources cited were reliable and trustworthy, all coming from academic journals. There does not appear to be any significant bias. I noticed that this article could be more specific as to what "long-term wear" means with respect to the different complications arising from contact lens wear.

Additionally, the article does not mention a serious side effect of long-term contact lens wear, which is corneal neovascularization. The article should also mention what a commentor has already stated, which is that the risk corneal neovascularization has been reduced due to the usage of modern silicon hydrogel materials in contact lens making. I will add a link to that page in this article and cite sources from NCBI to support my claims. I could also add information explaining oxygen transmissibility through different contact lens materials and how that has improved over the last few decades.

Not all contact lenses are worn to correct vision- some are worn cosmetically. I will look into the literature on long-term effects of cosmetic contact use and add what I find pertinent to the pre-existing sections.

My contribution will be largely focused on the "Structural Change" and "Functional Change" sections. Medicine2025 (talk) 06:58, 25 November 2024 (UTC)[reply]
