Cataract surgery with Multifocal Lens Implants
Cataract surgeries have come a long way from being a major procedure and have become a simple outpatient surgery today. The recovery is no longer prolonged and the vision is recovered almost immediately after the surgery. One of the remarkable innovations in this stitchless surgery has been multifocal lens implant.
Studies have shown that patients who are implanted with multifocal lenses experience better near and distant vision in comparison to those who get monofocal lenses. The conventional monofocal lenses primarily correct distant vision, which necessitates use of eyeglasses or contact lenses for near vision.
The efficacy of multifocal lenses
Multifocal lenses are nothing new to the world of cataract surgery lens implants. They have been FDA approved and in use for more than a decade now. This has also meant that there have been several improvements in the way these are designed so that patients get the best vision after surgery.
Studies have shown that 3 months after surgery people who get multifocal lens implant enjoy better average near vision than patients who opt for monofocal lenses. The average corrected distant vision is also superior. This means that people with multifocal lenses are less dependent, and most of the times independent, of spectacles.
Multifocal lenses may take time to adjust
Even though the innovations in lens technology have meant that patients may experience flawless recovery of near and distant vision right after surgery, there are some exceptions. It must be understood that the brain needs to learn a new method of processing visual information it receives to give you the image of objects that are far or near. So, multifocal lens implants may require some adjustment.
The adjustment is best if multifocal lenses are implanted in both eyes. The correction rings of different strengths, that multifocal lenses have, enable correction of both near and distant visions efficiently. It must be kept in mind that just like any lens implant, the patients may experience visual disturbances like glare and halos. Patients who experience night vision problems with multifocal lenses are usually prescribed antiglare glasses while driving to minimize them. These issues must be discussed with your cataract surgeon in Michigan.
The future of multifocal lenses
The experts have long been working on bringing more elasticity to the multifocal lens implant to replicate the quality of natural lenses. This effort has seen a lot of success in the recent past. An elastic lens can itself be reshaped by the eye muscles in order to focus better with both near and far vision.
