Reading eye prescription

Hello all

I have previously requested help from this group with learning why I was told by my specialist that I should consider getting iols for MONOVISION.

The replies were helpful.

Here is my eye prescription from two years ago (ie, prior to my latest exam which identified the need for cataract removal and iol insertion.)

RIGHT eye

sphere -3.25

cyl -1.75

axe 95

ADD 2.50

Seg 23

LEFT eye

sphere -.25

cyl -1.5

axe 65

ADD 2.50

seg 23

Can anyone tell me if there is there anything in this prescription that would indicate that I would be a good candidate for MONOVISON iols (as opposed to Monofocal or Multifocal iols)?

Thanks in advance.

    There are a couple of things to consider based on what I have learned so far:

    .

    1. Your eyeglass prescription is the sum of the refractive issues in your natural lens and your cornea. In an IOL operation you are replacing the lens, so errors in the lens are eliminated. Whether or not you need a toric IOL (to correct for astigmatism) is determined by your cornea.. You need the cornea topography to determine whether or not you need a toric lens. If you do need a significant toric correction (>- 0.70), a toric lens is the best way to deal with it.
    2. Monovision vs multifocal correction is a whole different matter. It all depends on your priority to be without eyeglasses and what your are willing to tolerate to do it. Monovision has compromises too. Each person has to evaluate what their priorities are.

    Hi - your current eye glass prescription won't indicate whether you are a candidate for monovision. If you visit your optometrist you can simulate with contact lenses provided your cataracts aren't distorting your vision a lot.

    Most people can tolerate a micro or mini monovision of 1 diopter between the eyes. If there is a big difference you could experience double vision and depth perception could be compromised.

    Still many opt for mini monovision to provide a bit more range of vision than targeting eyes the same. Given the healing process where IOL shifts eyes could end up .50 diopter difference anyways.

      Thank you for this reply. I appreciate it very much.

      Assuming a successful contact lens simulation, can you tell me what, exactly, will the optometrist be providing to the specialist? In other words, what does the specialist doctor seek from this simulation?

      Thanks again.

      The simulation is more to help you decide if a monovision set up would work for you. I don't think the optometrist provides any assistance (other than referral) to the surgeon. But knowing how much monovision (if you are able to simulate that with contact lenses) the surgeon will be able to work that into the calculations. Surgeons do a lot of that type of set up with patients opting for monofoxal lenses. Just be sure to have that discussion with him-her.

    typically a monofocal implantee would need a +3.5 reader for close up vision 13 inches to 20 inches and +1.25 for intermediate distance. 22 to 40 inches. however what you need varies from person to person. danish viking was well versed with this near acuity readings but he is currently away from the forum.
