keratomileusis

 [ker″ah-to-mĭ-loo´sis]
keratoplasty in which a slice of the patient's cornea is removed, shaped to the desired curvature, and then sutured back on the remaining cornea to correct optical error.
laser-assisted in-situ keratomileusis (LASIK) keratoplasty in which the excimer laser and microkeratome are combined for vision correction; the microkeratome is used to shave a thin slice and create a hinged flap in the cornea, the flap is reflected back, the exposed cornea is reshaped by the laser, and the flap is replaced, without sutures, to heal back into position.

LASIK

[lā′sik]
acronym for laser-assisted in-situ keratomileusis, a retractive surgery on the cornea in which the excimer laser and microkeratome are combined for correction of distance vision. The microkeratome is used to shave a thin slice and create a hinged flap in the cornea, the flap is reflected back, the exposed cornea is reshaped by the laser, and the flap is replaced, without sutures, to heal back into position. Preoperatively, a topical antibiotic and topical anesthesia are instilled into the eye. Postoperatively, the patient receives antibiotic drops and antiinflammatory drops and wears goggles for 24 hours to prevent slippage.

LASIK

Laser-assisted in situ keratomileusis Ophthalmology A type of laser ocular surgery in which the cornea is flapped open and the cornea shaved to correct either near– or farsightedness Statistics 750,000 Americans were LASIK'd in 2000; 90+% of treated Pts achieve better than 20/20 vision Criteria < –12––15 diopters for nearsightedness; +4–+6 for farsightedness Complications Ocular blowout 2º to corneal perforation, flap wrinkling/misalignment, epithelial ingrowth into stroma resulting in vision defects–glare, halos, diminished contrast, ↓ light passing to the pupil, lifting of the cornea with irregular astigmatism.

LASIK

A surgical procedure on the cornea aimed at correcting ametropia. A suction ring is applied to the globe and an increase in intraocular pressure to approximately 65 mmHg is induced for a maximum of two minutes. During that time an automated microkeratome advances across the cornea creating a corneal flap of about 8.5 mm in diameter, which contains the epithelium, Bowman's layer and a portion of the anterior stroma. The vacuum is then switched off and the suction ring removed. The corneal flap, which is hinged on one side of the cornea, is turned round onto the conjunctiva and the exposed stroma is ablated with the excimer laser. On completion of the laser ablation, the corneal flap is repositioned and left to adhere without sutures. There are some complications associated with this procedure, but it gives rise to less postoperative pain and more rapid visual rehabilitation than other similar surgical procedures (Fig. L4). LASIK is an acronym made from the following italic letters 'laser in situ keratomileusis' or 'laser assisted intrastromal keratoplasty'. See corneal ectasia; epikeratoplasty; Intacs; keratome; keratomileusis; keratophakia; photorefractive keratectomy.

Patient discussion about LASIK

Q. Has anyone had a bad experience with Lasik? I am considering the procedure but am worried about the risks.

A. i know several ophthalmologist- and they all ware glasses...it's like a giant experiment on people- no one really knows what will be the long reach out come of it. but then again, cellular radiation is also a world wide experiment..so i stay with my glasses for now, but that's because i'm not a big risk taker.
