Based in Rockville, Maryland, Dr. Anthony Roberts provides client-centered ophthalmology care for a broad range of eyesight issues such as glaucoma, corneal disease, dry eyes, and diabetic retinopathy. Offering advanced Lasik procedures, Dr. Anthony Roberts provides extended-depth-of-focus (EDOF) intraocular lens (IOL) options to patients with complex vision challenges. IOLs are typically implanted as part of refractive lens exchange or following cataract extraction, within the surgical treatment of presbyopia. Traditional multifocal IOLs employ diffractive optic lenses and separate light between near, intermediate, and long distances. This means that the user is only able to focus on a single distance at a time, with blur, halo, and glare sometimes occurring due to the multiple focal points. By contrast, EDOF-IOLs provide a single elongated focal point that seamlessly improves depth of focus and range of vision. This emerging technology is ideal for patients who do not want their functional vision compromised as they shift focus across distances.
