Traumatic dislocations of LASIK flaps, though rare, can occur years after the vision correction surgery. That’s the take-home message of the report of two cases of traumatic LASIK flap dislocations published in Journal of Refractive Surgery.

Late LASIK flap dislocations are rare, but possible
June 17, 2010Toric phakic IOL provides better night driving vision than PRK
June 1, 2010An implantable phakic IOL designed to correct both myopia and astigmatism improves simulated night driving vision more than PRK, according to a new study. Researchers in San Diego compared changes in simulated night driving performance among patients moderate to high myopia and astigmatism after treatment with either surgical implantation of a toric Visian Implantable Collamer Lens (STAAR Surgical; Monrovia, Calif.) or conventional PRK surgery.
Surgeons discuss humidity, corneal hydration and laser eye surgery
April 20, 2010Refractive surgeons agree that the condition of the surface of the eye (cornea) before, during and after LASIK and other laser eye surgery is an important factor in visual outcomes of the surgery. In the April 2010 issue of EyeWorld, a panel of eye surgeons discussed the importance of the ambient humidity and temperature in the laser surgery suite and eye hydration before, during and after surgery to achieving predictable, high-quality visual results.
Study reveals long-term outcomes of LASIK and PRK for high myopia
March 25, 2010A 10-year study of outcomes of LASIK and PRK for the correction of greater than –10 diopters (D) of myopia reveals many patients still need prescription eyeglasses to see clearly. Lens-based refractive procedures, such as phakic IOL implantation, are now more popular than laser vision correction for the surgical treatment of high myopia.
PRK safe, effective for hyperopia and accommodative esotropia, study finds
March 18, 2010PRK may eliminate the need for prescription eyeglasses and straighten the eyes of young adults with low to moderate hyperopia and purely accommodative esotropia, according to a new study. Researchers at Emory University School of Medicine (Atlanta, Ga.) performed a retrospective chart review of 40 patients ages 17 to 39 years who underwent bilateral photorefractive keratectomy (PRK) to eliminate their dependence on glasses.
Custom PRK corrects moderate myopia better than wavefront-guided LASIK, study finds
December 9, 2009A new study conducted in Brazil has found that wavefront-guided wavefront-guided LASIK for the correction of moderate myopia. Eighty-eight eyes of 44 patients with moderate myopia were randomly selected to undergo either wavefront-guided (custom) PRK or custom LASIK. The mean amount of pre-operative myopia was -3.85 diopters (D) among the PRK eyes and -3.99 D among the LASIK eyes.
LASIK and PRK cause no long-term problems with corneal endothelium
November 18, 2009A new long-term study of LASIK and PRK shows the laser vision correction procedures have no adverse effects on the corneal endothelium. The endothelium is the innermost layer of cells in the cornea that controls the hydration and clarity of the front of the eye.
Long-term study finds LASIK and PRK safe, effective for treatment of moderate to high myopia
November 4, 2009A common concern among people considering laser eye surgery is whether the procedure is safe and effective — both immediately and years after surgery. Researchers in Spain recently conducted a 10-year follow-up study of patients who underwent either PRK or LASIK for the correction of -6.00 to -10.00 diopters (D) of nearsightedness.
Long-term study finds PRK safe
September 21, 2009A new long-term study has found that PRK does not appear to cause retinal detachment or other vitreo-retinal complications. The retrospective study followed 455 eyes that underwent photorefractive keratectomy (PRK) for a period of up to nine years after surgery.
Lasers used for eye surgery do not interfere with pacemakers, study finds
August 7, 2009Excimer lasers used in LASIK and other laser eye surgery do not appear to interfere with the normal operation of implanted pacemakers and defibrillators used to treat heart problems. That’s the finding of recent research by Neil A. Sher, MD, adjunct clinical professor of ophthalmology at the University of Minnesota (Minneapolis).
