Talk:Excimer laser

Previous discussions without headers
Excimer lasers (excited dimer) are very important in the fields of optometry and ophthalmology. Equal numbers of males and females, who commonly were pre-existing contact lens wearer have decidided for reasons such as sport, work and inconvienience to have photorefractive surgery performed (laser eye surgery). This surgery should remove any need of spectacles.

there are two main photorefractive procedures. The first is Photorefractive Keratectomy (PRK), and the second is Laser instu Keratomeilus (Lasik.

In both procedures, the laser is used to change the shape of the cornea. For myopes the corneal profile is flattened, for hyperopes the peripheral cornea is abblated effectively flattening the cornea.

PHOTOREFRACTIVE KERATECTOMY

Procedure:

A speculum is inseterd to separate the eye lids. The cornea is anaestatised. The patient fixates on a target. The corneal epithelium is removed via manual, mechanical (amoils rotary brush), or means of alcohol. The laser ablates the cornea at descemets membrane and the anterior stroma.

Post operatively: Pain, poor vision, ocular lubricats given to the patient, the vision will stabalise in 6 to 12 weeks

Complications: (Early), Sterile infiltrates, haloes, glare and mild ptosis.

Removed
I removed this line:
 * Some examples of excimer lasers:Aluminum Nitride, Aluminum Oxide, Beryllium Oxide, Aluminum Alloy are just some examples.

Since this doesn't seem to be anything to do with excimer lasers. Perhaps someone was mixing them up with semiconductor lasers? --Bob Mellish 19:26, 12 November 2005 (UTC)

I had also removed the table entries for F2, Cl2, and N2 which are of course not excimers (but you sometimes see F2 lasers mentioned in the same context). K64u69 tried to reintroduce F2 but I reverted that, for the same reason. Maybe these UV lasers need mention, but cannot properly be called "excimer" as I understand it. Or change the article to "UV lasers." Interferometrist (talk) 13:20, 4 February 2011 (UTC)

By the way, K64u69 please do NOT mark an edit as "minor" unless it really doesn't change the meaning (beyond fixing a typo) and CAN'T be controversial. If you mark it minor then people don't notice your edit on their watchlist. OK? :-) Interferometrist (talk) 17:26, 4 February 2011 (UTC)

Comment about removal of the F2 laser. The majority of the chemical literature and manufacturers refer to the fluorine laser as an excimer laser. True, the Cl2 and N2 are not usually referred as such. I almost always see the F2 referred to as an excimer.Davidbaddison (talk) 07:02, 6 February 2011 (UTC)Davidbaddison


 * I don't mind including it in the article as long as the text isn't misleading. But we agree that "excimer" would be a misnomer in the case of F2. With that stipulation it could be mentioned, but there wasn't anything special said about it anyway. How about a line (why don't YOU edit it!) saying that "manufacturers refer to the fluorine laser as an excimer laser...." even though it technically isn't? But please provide a reference then.Interferometrist (talk) 19:49, 6 February 2011 (UTC)

Excimer Laser Annealing
Excimer Laser Annealing for low temperature polysilicon (LTPS) is a crucial step in the production of cellphone and tablet displays. It's a major application for the excimers, and is used to make the majority of cellphones produced today. This topic should definitely be included here. 70.175.149.15 (talk) 18:11, 24 March 2023 (UTC)
