Monovision Vs Multifocal Contact Lenses
Is it safe in general to "reverse" or "enhance" lasik monovision sugery? My wife (52 yrs. Old) had lasik monovision almost a year ago and can't stand it. She was not offered a contact lens to simulate it or we never would have agreed to the procedure. She
I'm going to try multifocal contact lenses. Should my quality of vision with these be the same as progressive glasses?
Use progressive lenses and monovision contacts. When I cover one eye objects appear larger in one eye than the other. Why is that?
Accidental telescope: The eye with the more minus contact lens sees the larger image because a minus lens acts as an eyepiece in a Galilean telescope, while the progressive bifocals act as the objective lens. This is of theoretical, but little practical value clinically. Either switch to bifocal contact lenses or correct both eyes for distance with the lenses and use over-the counter readers. Aniseikonia fixed. ...Read more
How do I stop cloudy film from forming inside my contac lens? I have been wearing gas permeable contact lenses without any significant problems. In the last 6 months, everytime I put my contact lenses on- the right lens gets cloudy and it has a film over
This: This could be a fit issue where debris is being trapped. It could also be the gpc as previously mentioned. I also see similar issues with severe lid inflammation and contact lens use - make sure you are cleaning your eyelids very well each day. I also feel patients that use make-up around the eyes need to be careful with contact lens use. It is amazing the amount of make-up that makes its way into the tear film. ...Read more
Contacts: Probably yes but please contact your eye doctor for certainty. ...Read more
Monovision IOLs: Monovision (one eye distance focus, one eye near) is a common method to correct presbyopia (loss of reading vision over age 40). The + is an increased independence from glasses. The - is a loss of depth perception and potential imbalance. A trial of monovision with contact lenses is recommended before surgical correction (cataract lens implants or laser vision correction). ...Read more
In monovision with contacts dr said my depth perception is lessened. How does this affect driving?
Worn monovision contacts for years but no longer see computer well. Would bifocal or multi focal contacts be worth trying?
Used monovision contacts for years& now want improved clarity & less glare with night driving. Are bifocal contacts a good alternative & comfortable?
My peripheral vision is better when I wear glasses instead of monovision contacts. Why would that be?
Monocular vision: The convenience of being fitted in monofocal contacts is to lessen need for glasses, at the compromise of reduced stereopsis (binocular vision). However I find improvement in peripheral vision when wearing contacts for optimum distance (binocular) vision, versus glasses. Each contact lens individual determines whether the reduction of stereopsis is satisfactory for their daily functions. ...Read more
What are good alternatives to monovision contacts other than distance only w/readers. I use a computer at work with detailed work.
Multifocal contacts: There are many brands of multifocal contact lenses - some are optimized for computer distance. It would be worth a trial with a few brands. ...Read more
Dr said my vision has improved and lowered power in my monovision contacts. He said it can happen with age. I'm 59. Is that common?
Yes: Prescriptions change over time. The elasticity of your cornea, the increasing density of your lens, and the accommodative ability of your eye muscle are all factors affecting your ability to see. Changing your prescription to accommodate your needs is common. ...Read more
Use monovision w/some blurring at distance & computer. Could single vision contact for distance eye & bifocal contact for near eye improve vision?
Monovision: Is very effective of roost people. Variations for the optimum distance (far, intermediate and near) can be obtained through single vision contact lenses or a combination of single vision lens and multifocal lens. Your eye care provider will be able to determine the power and variations from your examination. Be sure to verbalize your needs and illustrate to him/her the distances involved. ...Read more
IOL monovision: Changing vision with an IOL monovision usually is due to a tear film issue: meibomian gland dysfunction or dry eyes. Get a LipiScan to be sure glands look normal. Posterior capsular opacification (PCO) can also cause vision issues after cataract surgery. Consult with me either on HT or in my office in Rockville, MD. ...Read more

Work on computer all day, monovision laser procedure will be good for me? Far sight is very good.
Monovision: An easy way to know if that is something you will like is to simulate the same thing with contact lenses. I would try that for a month and see how you like it. Most of the patients that chose monovision with me have already had that experience with contact lenses and were used to it. Ask your surgeon to see if that is a good option for you. Good luck. ...Read more
Read lasik not so good after 40. But read the average age for lasik is 39? Also read most fix distance and not choose monovision. What % choose mono?
Lasik after 40:
Lasik can be life-changing and offer FREEDOM from glasses. Lasik to give 20/20 distance vision usually can/will last forever but your eyes change.
We all lose our focus power in our lens as we age whether we had perfect Lasik at 18 or not. This declining lens power is noticed about age 40 as decreased reading vision and most of us will just go buy some magnifying glasses to give us that power back ...Read more
Would you recommend monovision laser for a person that works all day with computers and read everyday for 30 minutes?
Contacts first: Before considering a surgical procedure for vision correction, I would recommend a trial of monovision contact lenses measured to allow the near focus for the computer monitor, and the dominant distance eye fully corrected. If you're able to tolerate this well, as long as your eyes are suitable candidates for laser vision correction, the procedure maybe right for you. You still may need glasses. ...Read more
Used monovision for many years. Had exam 1 mo. Ago & tested 20/20. Today reading vision was not good. Why the sudden change?
Have macular pucker with some distortion & macropsia but see 20/20. Can symptoms make it more difficult to use monovision. I get headaches.
Yes: Monovison (using one eye for distance and and another for near) may be difficult with a macular pucker. Metamorphopsia (distortion) will make the one eye function less than optimally for the task ...Read more
Trade-Off: Monovision is the correction of one eye for distance vision, the other for near. Although it allows some people to avoid glasses or contact lenses, it is a trade-off, since the difference between the eyes may disrupt depth perception or cause blurring due to ocular competition. It is wise to try this using contact lenses (reversible) before consenting to a surgical correction (irreversible). ...Read more
The same: As they do before cataract surgery - by correcting both eyes for distance and having a progressively stronger column in the bottom of the glasses for close work. By allowing both eyes to see clearly at all distances, this should allow good vision for those activities in which the mono-vision correction is not adequate. ...Read more
Progressive glasses: Most any eyeMD or optometrist can give you a Rx for progressive glasses after monovison cataract surgery. MD or OD will determine what power is needed & if your brain will tolerate them if large difference in power between both eyes. More info at: eyedoc2020 blogspot com ...Read more
