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.

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).
