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.

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)

[edit] Changed

Changed the longest pulse length to accomendate the Sirius1000 laser. Geraldebberink (talk) 10:20, 24 April 2008 (UTC)
