Are You a Good Candidate for Artificial Lens Implants?
- Posted on: Sep 18 2021
There are two main types of artificial lens implants: intraocular lenses (IOLs), for people with cataracts; and phakic IOLs, for the correction of nearsightedness or farsightedness. Dr. Gregory Pamel of Pamel Vision and Laser Group explains how artificial lens implants work and who is a candidate.
Intraocular Lens Implants for Cataract Surgery
IOLs are made of clear plastic or silicone and measure about ¼ inch in diameter. IOLs have been improving patients’ vision since their approval by the FDA 40 years ago. In that time, IOL technology has expanded greatly and new IOLs have evolved.
While the possibility of complications exists in any surgery, such occurrences are rare with IOLs. Patients may experience temporary redness or swelling, which should disappear quickly. There is the potential for dislocation, which is when the IOL moves out of position.
It can take between two and three months for an IOL to fully heal. During that time, patients should wear sunglasses whenever they are outdoors during the day and sleep with an eye shield on. While healing, avoid strenuous exercise or heavy lifting.
IOLs are suitable for patients whose cataracts are significantly affecting vision. Cataract patients may choose between monofocal and multifocal lens implants. The former helps correct distance or near vision, while the latter corrects both distance and reading vision.
Phakic IOLs
Those who are tired of needing glasses or contact lenses to see clearly may benefit from phakic IOLs.
Patients who are not candidates for LASIK may prove good candidates for phakic IOLs, especially if they are extremely myopic (nearsighted). Younger people may have better results with LASIK and other procedures, so most phakic IOL candidates are age 50 and up.
Candidates for phakic IOLs must hold realistic expectations and know they can handle any potential side effects. For instance, the incidence of dry eye increases with aging, and IOLs can exacerbate dry eye. A person already diagnosed with advanced dry eye is not an IOL candidate.
The same holds true for patients dealing with glaucoma, advanced macular degeneration, anterior basement membrane dystrophy and other eye diseases. Patients who have undergone previous refractive surgeries may not have a good outcome with IOLs.
