[edit] Article title
Tempted to move this to intraocular lens implant --User:Chinasaur
- Why? "Intraocular lens implant" returns 6430 hits on Google [1], while "intraocular lens" (without implant afterwards) returns 77100 hits [2]. I don't think your proposed move is a good idea, to my humble opinion. --Edcolins 21:30, Dec 10, 2004 (UTC)
- Although IOL is indeed the jargon, to the uninitiated that could be confusing, since the natural lens is logically also intraocular, so I could see why someone would propose such a move. Also, since intraocular lens implant contains "intraocular lens", searching for the latter would find the former (though I guess the ranking might be different). A-giau 07:25, 13 July 2005 (UTC)
- Revised Google search results: "intraocular lens": 533,000; "intraocular lens implant": 35,600; "intraocular lens" -"intraocular lens implant": 484,000; and of course "intraocular lens implant" -"intraocular lens": 0. User:Ceyockey (talk to me) 02:46, 22 May 2006 (UTC)

[edit] Out of Date
The "Artisan lens" has been renamed to 'Verisyse' and has been FDA approved http://www.fda.gov/cdrh/mda/docs/p030028.html I'm also considering a cleanup with a clear distinction between the Phakic version (normally used as a replacement for contact lenses) and the ... uh... non-phakic version, where the natural lens is replaced -- to treat clouding of the lens. --Mdwyer 21:48, 4 April 2006 (UTC)
The commonly used phrase for "non-phakic" is aphakic, as in "aphakic IOL" or "aphakic intraocular lens" :-) Don't know if there is a commonly used abbrevation for aphakic IOLs, though? When you say IOL, you normally mean aphakic IOLs, because the number of cataract surgeries are currently much higher than surgeries for correcting refractive errors. Though this might change in the future (10 years?)... -- di92jn
Hmmm... Apparently "pseudophakic" is used for IOLs when you replace the natural crystalline lens with an artificial one. If you want to be precise, "aphakic" means the absence of a lens in the eye, and "phakic" means that there is a lens present. Don't know if this should be part of the article? Guess it should... -- di92jn
[edit] Verisyse versus Artisan
The FDA documents suggest that Artisan and Verisyse are the same thing "Verisyse (Model VRSM5US and VRSM6US) also known as ARTISAN (Model 206 and 204) Phakic Intraocular Lens (IOL)", but the artical lists one as silicone and the other as acrylic. PMMA is the same as Acrylic. --Mdwyer 21:54, 4 April 2006 (UTC)
Acrylic:
- Ophtec produced the Artisan® lensacrylic IOLs.
Silicone:
- AMO (Advanced Medical Optics) produces the Verisyse™ lens.
[edit] Cleanup Tag from July 2005
Here is the Diff between the edit that introduced the {{cleanup}} tag and the edit in place as of the writing of this comment. I'm of the opinion that the cleanup-tag can be removed. Would someone like to second that and actually remove the tag? User:Ceyockey (talk to me) 02:52, 22 May 2006 (UTC)
[edit] "Corneal Incision, etc
-- User:Steve McGrew I deleted the word "corneal", as the incision isn't made in the cornea, but in the white of the eye above the cornea. I also broke the paragraph before the Crystalens into two paragraphs, as the addition of the crystalens data made reading it clumsy.
I didn't change the statement that it requires a larger incision than traditional implants, but considered it as I've been researching this (I had the multifocal lens implanted in my left eye) and Wikipedia is the only place I've seen this. I'll ask my eye surgeon when I see her in September for the checkup. If she says the incisions are the same time I'll do a further edit. If any of you are eye surgeons have experience implanting these things, please clear the matter up. A citation would be helpful.
- The number of incisions change depending on what the doctor foresees is needed. Sometimes, the number of incisions are greater than actually needed - the surgeon makes the incisions "just in case", because it is more difficult to make incisions in the eye after a while, when the eye is softer because fluids has leaked out. Also, the locations - for example in the cornea or the sclera (the white of the eye) - and their locations depends on the lens type; is the lens inplanted in front of the iris, or behind it? Is the lens aphakic or phakic? Is the lens foldable or not? Please note that I'm not an eye surgeon, just very interested... --User:Di92jn
[edit] Merge header
I currently have no strong opinion as to whether Pseudophakia should merge to Intraocular lens. I think it is worth noting that with the advent of phakic IOLs, not everyone with an intraocular lens has pseudophakia. -AED 21:40, 1 October 2006 (UTC)
[edit] Materials Confusion
This article commonly makes notations about PMMA and acrylic lenses, describing the two as entirely different materials. In fact, these 'two' materials are both the same thing - PMMA stands for polymethyl methacrylate, most commonly known as plexiglas, perspex, acrylic glass, or acrylic. Any other materials considered as 'acrylic' are unsuitable for the task - acrylic fiber appears white due to its highly refractive nature as a fiber and its impurities, whereas pure acryls by themselves are too reactive to be included as an implant material (They contain two double bonds, which are subject to easily being broken by free radicals and various components of one's body.). It is strongly suggested that the corrections be made. See the Acrylic glass article and the Acrylic disambiguation for more detailed information. Xander T. 03:08, 11 March 2007 (UTC)
