Symphony lens most commonly used in cataract surgery is a multifocal lens, which only allows the person to see at a distance, with closer objects being out of focus. In contrast, the symphony lens was specifically developed with features to improve both the range and quality of vision. Multifocal lenses use diffractive technology to give simultaneous vision by splitting light into multiple distinct foci. The symphony lens merges technologies to achieve these goals. One is the proprietary chelate design which elongates the focus of the eye, in order to give the extended vision. The new findings suggest the symphony’s advantages over older IOLs are less deceived than hoped. Approved by the US Food and Drug Administration in July 2015, the symphony had reached the market earlier in many other countries. The symphony lens is a multifocal lens that provides clear visions at all the distances. The benefit of symphony lens provides our Philadelphia, PA, patients with an intraocular lens that stands out from others on the markets and offers superior vision results. There are several advantages of symphony lens which include;
1. Clear vision at all distances: symphony lens is a multifocal lens meaning that it corrects both near and distance vision. Most multifocal lenses have breaks that make transitions between various distances a little rough. Individuals with healthy eyes will benefit from clear, dependable vision at all distances.
2. Reduced glares and halos: Halos and glares are significantly reduced in multifocal IOLs. As light enters the IOLs, it is divided to create multiple images on the retina to allow for near and distance vision. The symphony lens is designed to provide a smooth transition from day to night vision, with minimal visual abnormalities. After recovering from cataract surgery, patients with symphony lens report little to know halos or glares.
3. Less dependence on prescription lenses: When a person receives a traditional IOL it treats distant vision and the patient wears glasses for reading and other up-close tasks. However, this is uncommon for those with multifocal IOL to reach for reading glasses. Patients who receive the symphony lens typically do not depend on reading glasses to perform closer task thus little need for prescription lenses.
4. Can live a healthy and active lifestyle: Once you have recovered from your cataract surgery, you will be able to live an active and healthy life once again because your full range of vision will be restored enabling activities like reading, playing driving and many other activities.
5. High patient satisfaction: Patient with visual problems get the satisfaction of their sight by using symphony lenses which provides a clear vision to longer distance.
6. Seamless day-to-night vision: Patient with poor night sight benefits from symphony lenses because symphony lenses provide a clear vision to longer distances both at night and also during the day hence providing require the solution to affected patients.
7. Reduces need for intermediate and distance spectacles: While traditional mono-focal IOLs are designed to restore far or distances vision, symphony lenses provides quality vision at multiple distances and eliminate the need for glasses.
8. No upkeep is required: Most patients receive lasting results with this lenses because these lenses are planted in the eye hence no upkeep is required, that means that you do not have to soak them or replace them after getting scratched, as you would with glasses.
9. Saves money: Unlike glasses that are replaced every now and then, which leads to a lot of money being spent for replacement, symphony lenses are once paid for and implanted for once without any cost of replacement.
10. Provides multiple distinct foci: Multifocal lenses use different technologies to give simultaneous vision by splitting light into multiple distinct foci.
1. Blurry vision: Multifocal lenses give people difficulty to see up close, this gives blurry vision when doing activities like reading books.
2.Contrast after cataract surgery: After cataract surgery, the symphony lens makes reading in dim light difficult, and reading using symphony lenses in dim light may give one another difficult vision problem.
3. Existence of glare and halos to some patience: Small number of patients who receive multifocal lenses experience glares and Halos around lights after dark, which can make driving at night difficult.
4. Expensive to acquire: Multifocal lenses are more expensive than monofocal lenses and even glasses this makes it difficult to be acquired by patients with low income.
5. Uneasy to replace: Symphony lenses are implanted to last for longer periods after cataract surgery hence difficult to replace when they get destroyed and when they get affected.
6. High risk during cataract surgery: Operating an eye is a risky operation during surgery and a slight mistake by surgeons may lead to patients losing the sight permanently.
7. View number of cataract surgeons: Cataract surgeon experts are few and not evenly distributed across the world hence making some of the developing and third world countries difficult to access the services of cataract surgery and implantation of symphony lens to patients in those countries.
8. May increase complications: Symphony lens may not be adaptable to some of the patients and may increase complications of visions ton the sight of the affected patients.
9. Longer initial examination: It takes the process of examination before the patient undergoes cataract surgery; this makes affected patients suffer vision problems before the symphony lens is implanted.
10. Require regular office visit for follow-up: Regular visit to experts for a check-up is a waste of time and also a waste of money for costs like transportation to required offices.
