New prismatic IOL appears effective in improving vision in advanced AMD patients

CHICAGO — Implanting a new prismatic IOL in patients with late-stage age-related macular degeneration may be effective in improving some aspects of patients' vision, one surgeon said here.
"I think [late-stage AMD] could be called the forgotten phase," said Charles M. Claoué, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery. "These patients tend to be discharged from the clinic, and there's not much active intervention at present, and this is sad because much of the retina is still healthy."
Dr. Claoué and colleagues implanted two advanced AMD patients with a Rayner P-Flex prismatic IOL after phacoemulsification. The new IOL design features a Fresnel prism.
"It has a hydrophilic acrylic platform with anti-vaulting closed-loop haptics," Dr. Claoué said.
Both patients had vision worse than 20/200 preoperatively and underwent in-the-bag implantation of the new lens in January.
"There was no improvement in uncorrected visual acuity," Dr. Claoué said. "This is not the aim of the lens."
Instead, both patients reported losing their central scotomas postoperatively.
"More importantly, from the point of view of me being able to sleep easily at night, they had no double vision," Dr. Claoué said.
