Dr. Murrell recently removed my cataracts and replaced them with a Symfony Lens. The procedure was painless. I am very pleased with the lenses and I no longer require glasses except for reading small print. I do experience the halo effect, mainly at night, around lights. But even with that small problem the improvement in sight (far, intermediate and near) certainly out weights the halo effect. I am extremely happy with the decision to spend extra and get the Symfony Lens. I also feel Dr. Murrell and his staff are very professional and easy to work with.
