How Intraocular Lenses Work for Many Patients
Are you living with cataracts or exploring your options to sharpen your vision? You may have heard the term “intraocular lenses” from a friend who saw success with this type of correction or an eye doctor getting to know your vision needs. But, what exactly are those lenses and how can they work for you? Here’s what you need to know about the different types of intraocular lenses and whether they are right for you
What Are Multifocal Intraocular Lenses?
Multifocal intraocular lenses (IOLs) offer cataract patients or baby boomers the chance to reduce their dependency on glasses or contacts because they are implanted inside the eye to correct vision both up close and far away.
Before multifocal IOLs, this surgery was performed to provide patients with clearer distance vision—think driving or watching TV. When it came time to read the menu at a restaurant or work on the computer, these patients needed to wear bifocals or reading glasses to correct presbyopia—loss of near vision focus—brought on by surgery. With multifocal IOLs, presbyopia can be addressed and corrected, so you can seamlessly transition from one activity to the next without the need to pull out your glasses.
In instances where patients need astigmatic correction, multifocal toric IOLs are available for those patients. The toric IOL component corrects the patient’s astigmatism.
Although multifocal IOLs may not be able to fully correct vision in all patients, most patients report they can go glasses-free comfortably or only need glasses for certain activities. Multifocal IOLs are available for patients with and without astigmatism.
Are You a Candidate for Multifocal IOLs?
While multifocal IOLs offer the convenience of being less dependent on glasses, there may be some compromise in the quality of vision. Accepting or refusing this compromise plays a big role in determining if you are a good candidate for multifocal IOLs.
Multifocal IOLs are ideal for patients with cataracts and are best implanted during laser cataract surgery to ensure proper placement for the best results. To be a candidate for multifocal IOLs, your eye specialist may require choosing a laser procedure for your cataract surgery. For a small percentage of patients, a LASIK enhancement procedure may be necessary to obtain the desired surgical result.
Finally, other pre-existing conditions, like macular degeneration, may mean multifocal IOLs are not right for you. However, only your eye doctor can recommend the best plan of action to regain your vision. A thorough pre-operative consultation would address if you are considered an ideal surgical patient.
Other IOL Considerations
Implantable Collamer Lens
If you are between 21 and 45 years old and have moderate to severe myopia, implantable collamer lens (ICL) may be your answer. During the procedure, an eye surgeon will place a permanent soft lens called the ICL behind your iris, which makes it unnoticeable to the naked eye, and can correct extreme nearsightedness.
Refractive Lens Exchange
In the absence of cataracts, refractive lens exchange (RLE) can correct farsightedness.
nearsightedness, and presbyopia. During the surgery, your natural lens is removed and replaced with an intraocular lens to give you sharper vision.
