A new study conducted in Brazil has found that wavefront-guided PRK with application of low-dose mitomycin C (MMC) is more effective than 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 [Read More …]
Custom PRK corrects moderate myopia better than wavefront-guided LASIK, study finds
December 9, 2009LASIK 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).
Thin-flap LASIK provides faster results than PRK, study says
August 5, 2009Though LASIK is the most popular laser vision correction surgery in the United States, photorefractive keratectomy (PRK) eliminates the risk of intra-operative and post-operative flap-related complications.
PRK safe for correction of myopia, says long-term study
July 1, 2009PRK, or photorefractive keratectomy, is safe for the correction of both low myopia and high amounts of nearsightedness, according to a long-term follow-up study of the procedure. Researchers in Italy followed 31 patients who underwent either unilateral or bilateral PRK in 1991 to 1993. A total of 49 nearsighted eyes were included in the study, and check-ups were performed every two years over a period of 14 years.
Study finds few enhancements needed after wavefront-optimized LASIK and PRK
June 29, 2009A study conducted at Emory University finds the overall rate of re-treatments (“enhancements”) required after wavefront-optimized LASIK and PRK is 6.3 percent. But patients who are farsighted or have at least -1.00 diopter of astigmatism prior to surgery are significantly more likely to need an enhancement.
Night vision may improve after wavefront-optimized laser eye surgery
June 19, 2009People undergoing wavefront-optimized laser eye surgery are more likely to see better at night than to experience a worsening of their night vision after the procedure, according to new research conducted at Emory University. Wavefront-optimized LASIK and PRK use a semi-customized excimer laser treatment designed to control a specific type of higher-order aberration called spherical aberration (SA).
LASIK and PRK found safe, effective for treatment of accommodative esotropia
April 29, 2009LASIK and PRK appear to be safe and effective treatments for children and young adults who have a binocular vision anomaly called accommodative esotropia, according to a recent study conducted by Italian researchers. The findings may change the way surgeons treat certain cases of the eye alignment problem to prevent the development of amblyopia (or “lazy eye”).
