People with misaligned eyes (strabismus) can safely have refractive surgery and expect excellent results. That’s the finding of a new study that evaluated the effect of LASIK, LASEK and phakic IOL implantation to correct refractive errors in eyes with esotropia and exotropia.

Wavefront-optimized LASIK produces excellent visual outcomes but increases higher-order aberrations
July 19, 2010Wavefront-optimized LASIK produces excellent visual acuity when measured with an eye chart, but increases higher-order aberrations that may affect low-contrast vision, according to a new study. Wavefront optimized LASIK is an advanced type of LASIK surgery designed to correct nearsightedness, farsightedness and astigmatism, and also produce sharper vision by inducing less spherical aberration — a specific type of higher-order aberration (HOA) — than conventional LASIK.
Laser advances producing better LASIK outcomes, study finds
July 14, 2010Advances in laser technology are producing better visual outcomes after LASIK, according to interim results of the ongoing LASIK in U.S. Naval Aviator Study.
In its July 1, 2010 issue, Ophthalmology Times reports the current findings of the study presented by Capt. David J. Tanzer, MD, at the recent annual meeting of the American Society of [Read More …]
Laser flaps may reduce post-LASIK dry eye
July 9, 2010All-laser LASIK — with the corneal flap created with a femtosecond laser — may help speed healing of the cornea and cause less post-surgical dry eye, according to an experienced refractive surgeon. In an article published June 25 in Ocular Surgery News, eye surgeon Kerry D. Solomon, MD, said the “inverted bevel” side cut made with the latest IntraLase femtosecond laser) may result in faster corneal healing, which can shorten the symptoms of post-LASIK dry eye.
LASIK safe, predictable for correction of myopia in Asian eyes
July 7, 2010LASIK is safe and predictable for the correction of up to -10.00 diopters (D) of myopia in nearsighted Asian eyes, according to a new long-term study.
Researchers in Singapore conducted a study of 37,932 eyes of 19,753 patients that underwent LASIK surgery for the correction of myopia between 1998 and 2007 at the Singapore National Eye Centre.
Range of laser flap thicknesses produces similar LASIK outcomes
June 22, 2010One of several variables that could affect LASIK outcomes is the corneal flap created in the first step of LASIK, including physical characteristics of the flap. In this month’s issue of Journal of Refractive Surgery, researchers in India report the results of a study of the effect of four target thicknesses of femtosecond laser-created corneal flaps on LASIK outcomes.
Monovision LASIK produces good distance and near vision for presbyopes
June 15, 2010Monovision LASIK may be the answer for people over age 45 who want to reduce their dependence on reading glasses after vision correction surgery. That’s the conclusion of researchers in Madrid, Spain, who investigated the visual outcomes of the modified LASIK procedure in a study published online by American Journal of Ophthalmology.
LASIK induces fewer higher-order aberrations than CRT contacts
June 10, 2010LASIK causes less spherical-like aberrations than special contact lenses that are used to correct myopia non-surgically. That’s the finding of researchers at Mount Sinai School of Medicine (New York, NY) who compared the refractive and visual outcomes of the two procedures in a study published in Journal of Refractive Surgery.
All-laser LASIK tops CK for monovision correction of presbyopia
June 9, 2010If you are over age 40 and have perfect distance vision without prescription eyewear but have lost your ability to see clearly up close due to presbyopia, all-laser LASIK may be a better vision correction option than conductive keratoplasty (CK), according to a new study published in Journal of Cataract & Refractive Surgery.
Eye may adjust to aberrations caused by LASIK
June 8, 2010The human eye may be able to self-adjust and partially compensate for optical aberrations caused by LASIK eye surgery, according to a new study. LASIK, PRK and other corneal refractive surgery have been shown to increase higher-order aberrations in the eye that can affect visual clarity. Even customized, wavefront-guided LASIK typically increases these aberrations to some extent.
