We have monovision with LASIK and monovision with IOLs, which is tried-and-true and has been around for a long time in many forms.
I think it works very well, but it’s not the ultimate answer because a little bit of stereopsis and distance vision are lost.” Daniel Durrie, MD, in private practice with Durrie Vision in Overland Park, Kan., says ophthalmologists are changing the way they talk to patients about correcting presbyopia.
“It has made it a lot simpler to come up with the best solution for each patient,” he says. Durrie notes that presbyopia is part of dysfunctional lens syndrome, which has three stages.
Stage 1 typically starts around 43 years of age and goes until the early 50s.
Treating cataracts involves removal of the cloudy lens inside of the eye and replaces it with a clear and biocompatible intraocular lens (IOL).
This lens will provide the patient with better vision primarily at only one distance, up close or far away.During this time, the lens loses its ability to focus.In stage 2, which occurs during the 50s and 60s, the lens turns yellow and hazy.Most people require reading glasses as they reach middle age for this reason.The Crystalens belongs to a select category of high tech intraocular lenses commonly called 'multifocual intraocular lenses'.
