The current review was planned to analyse and compare femtosecond-assisted laser in-situ keratomileusis
(LASIK), the latest refractive procedure, with conventional techniques in refractive surgery.
Laser in situ keratomileusis
(LASIK) is currently the most common refractive surgery procedure.
WaveLight Excimer Lasers are prescription medical devices that are approved for use in performing laser-assisted in-situ keratomileusis
(LASIK) to correct certain kinds of nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
In addition to keratoconus, cross-linking has been proposed as a therapeutic option for iatrogenic keratectasia in photorefractive keratectomy (PRK)  and laser-assisted in situ keratomileusis
(LASIK) [38,40], infectious corneal ulcers , pellucid marginal degeneration , and bullous keratopathy .
Comparison of photorefractive keratectomy and laser in situ keratomileusis
for myopia of -6 D or less using the Nidek EC-5000 Laser.
Lasik, or Laser-Assisted in Situ Keratomileusis
, is a procedure that alters the shape of the cornea, allowing common vision problems like near- or far-sightedness and astigmatism to be corrected.
True (A) or false (B)--click on the correct answer: Corneal flap traumatic dislocation following in situ keratomileusis
is impossible because the flap is firmly sutured.
The LASIK Quality of Life Collaboration Project, a three-phase study, has been launched to assess the potential impact of laser-assisted in situ keratomileusis
on patient quality of life.
"Laser-assisted in-situ keratomileusis
(LASIK) has gained widespread popularity as a safe and effective surgical method for the correction of myopia, but patients with high [severe] myopia or thin corneas face some restrictions in avoiding the risk of developing keratectasia [a weakening of the cornea]," the authors write as background information in the study paper, published in the Archives of Ophthalmology, one of the JAMA/Archives journals.
Because of age-related conditions such as cataracts, older patients typically have been poorer candidates for refractive surgery, including the most popular method: laser in situ keratomileusis
