An 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.

Toric IOLs produce excellent visual outcomes
April 22, 2010Toric IOLs — premium intraocular lenses designed to correct astigmatism during cataract surgery and refractive lens exchange — produce excellent visual outcomes and high patient satisfaction, according to a new study. Researchers in Canada evaluated the bilateral implantation of AcrySof toric refractive IOLs (Alcon; Fort Worth, Texas) in subjects undergoing cataract surgery in both eyes.
Wavefront-guided LASIK found safe, effective for correction of myopia and astigmatism
July 27, 2009Wavefront-guided LASIK is safe and effective for treating low to moderate myopia (with or without astigmatism), according to a large-scale, multi-center study conducted by Optical Express.
Wavefront-guided LASIK induces fewer higher-order aberrations than wavefront-optimized LASIK
June 1, 2009A recent study finds wavefront-guided LASIK induces fewer higher-order aberrations than a related customized laser vision correction procedure called wavefront-optimized LASIK. Typically, fewer higher-order aberrations means better visual outcomes after LASIK surgery. The study suggests wavefront-guided LASIK offers the best results for most patients, with a lower incidence of re-treatments.
