Because the success rates with contact lens monovision range from 50% to 70%, at least half of the patients who try it may be unhappy with the results. Although monovision should be part of every refractive surgeon’s armamentarium, knowing its limitations and carefully selecting patients are paramount.
What are the disadvantages of monovision?
Disadvantages of Monovision
They include some decrease in overall distance vision, difficulty in seeing clearly at an intermediate distance (such as your computer screen), some loss of depth perception, and even some suppression of vision out of the blurry eye. In addition, driving is compromised, especially at night.
How long does it take to adjust to monovision after cataract surgery?
The monovision adjustment time is usually about a week or two. For the vast majority of patients, it takes less than a month to adjust.
Is monovision a good option?
While Monovision is not a “perfect” solution to presbyopia, for carefully selected patients, it is well tolerated and very satisfactory over 85% of the time. Most patients who choose Monovision are satisfied with both near and far vision without glasses.
Will I need glasses after monovision cataract surgery?
You can be expected to be glasses free for most of your daily activities due to increased focus depth with good vision for far, intermediate and near. However, you may still need a pair of glasses for backup, such as for nighttime driving or reading small print for a few hours or more.
Does monovision affect driving?
CONCLUSIONS: The results indicate that monovision does not adversely affect driving performance in daylight hours for adapted wearers. However, limitations in the study design are acknowledged, including the relatively small sample size, lack of standardisation of the habitual correction and the use of adapted wearers.
Do you lose depth perception with monovision?
Monovision lenses have long been known to cause a slight decline in depth perception because, as the name suggests, they compromise the person’s ability to see in stereo. That’s because a given object appears sharp in one eye and blurry in the other, so the brain suppresses the blurry image to some degree.
Does monovision work for everyone?
Although monovision does not work for everyone, it is a viable option for people who have presbyopia. Monovision can help you achieve good, functional vision at distance and near. It is not “perfect” vision, however.
Does monovision cause lazy eye?
The majority of our patients developed strabismus after 2 years of monovision, telling us that while a trial of monovision with a contact lens prior to surgery may suggest that the patient could tolerate monovision, it is not a guarantee.
Can monovision cataract surgery be reversed?
Although many patients will adjust well to monovision, some may find it uncomfortable. For those patients, the monovision can usually be reversed by elective laser vision correction, but this surgery will not be covered by your medical insurance.
Is monovision bad for your eyes?
The downside of monovision is that some people find it compromises the clarity of their distance vision too much, making distant objects appear slightly blurred. Others find monovision doesn’t provide adequate near vision to give them the freedom from reading glasses they were hoping for.
Which eye is usually done first in cataract surgery?
If there is a cataract in each of your eyes, typically cataract surgery is performed on your non-dominant eye first followed by your dominant eye 1-2 weeks later. The time between the two cataract surgeries is in case infection or complications occur.
How common is monovision?
Approximately 9.6 million people in the United States use monovision to correct both their distance and close-up vision. About 123 million Americans have presbyopia. Around half of those using monovision rely on contact lenses. The other half have undergone surgery to create the effect.
Does cataract surgery give you 20 20 vision?
It is a relatively quick procedure with a fast recovery time that restores a person’s quality of life. Some patients ask if they will have 20/20 vision after the procedure. Most patients can achieve 20/20 vision as long as they have no other conditions.
Is it normal for vision to get worse after cataract surgery?
No, your vision generally doesn’t deteriorate after cataract surgery unless other problems arise, such as macular degeneration or glaucoma. In cataract surgery, the eye doctor (ophthalmologist) removes the clouded lens from your eye and replaces it with a clear, artificial lens.
