Panoptix outcome and fine tuning with PRK
Posted , 3 users are following.
Been following the forum for a while and decided to go ahead with Panoptix as the risk of night vision PD was a trade off I was willing to make.
I recently received two Panoptix implants, 27 Sep and 4 Oct. Have been discharged by the surgeon and am pleased with the outcome being able to read at about 14'' see computer screen, dashboard and distance clearly. Pre surgery progressives prescription R +2.5 +0.5 145 Add +2.25, L +2.5 +0.5 20 Add 2.25. Wore progressives full time since age 40, now 65 so am very happy to be glasses free at this point.
Just got a refraction completed by my optometrist R+0.75 0 0. L +0.5 +0.5 50. Not sure if this is considered a good outcome or not but as I said I am pleased with the result and am fully functional with no glasses.
The question I've been leading up to is: would PRK laser correction be able to fine tune the refraction to Plano or would it risk an outcome worse that existing?
I look forward to your valuable comments and thank you in advance.

I would consider a positive number for the sph to be a negative. Something closer to zero and slightly negative would have been better. I presume the testing involved the "which is better-- 1 or 2" machine.
I am pleased that the effect has been good.

First, and I think most important is that if you are happy with the vision, then it certainly was successful. Could it be better? Yes, I think so. Both eyes were a bit of a miss to the plus side that makes you somewhat far sighted. This hurts distance vision some, and near vision more. Your prescriptions appear to be in ophthalmologist format with positive cylinder values. When converted to the more conventional negative cylinder values they are:
.
Right Eye: Sphere +0.75 D, Cylinder 0.0 D, Axis 90 Deg, Spherical Equivalent +0.75 D
Left Eye: Sphere +1.0 D, Cylinder -0.50 D, Axis 140 Deg, Spherical Equivalent +0.75 D
.
The surgeon seems to have done a very good job on the astigmatism (cylinder), but overall missed on both eyes by 0.75 D to the plus side. Did you get toric lenses? I see you had both eyes done in fairly quick succession, a week apart. That does not allow for healing and getting a good measure on the first eye outcome to adjust for the second eye. Perhaps coincidence but they missed both eyes by the same amount and in the same direction. Off, by one lens power step, or possibly two.
.
Prospects for getting a correction with PRK or Lasik, based on my experience are not that good. I wanted to make a correction to one eye to correct high astigmatism, and to increase the myopia. I saw two Laser clinics and both essentially told me the same thing. With Laser surgery they are normally correcting myopic eyes that are too steep. To do do this they make radial cuts in the eye to let it relax to a less steep shape. They can do this very well. However when the eye is hyperopic as yours are with your plus numbers, the eye is too flat. To make the contour more steep they have to make circumferential cuts out quite far from the center of the eye. That is more difficult and less predictable. That was what I was asking for, and was basically told they had no confidence in what the outcome would be. My optometrist further told me that when this type of correction is attempted that it tends not to hold, and may have to be done over and over again to restore the correction. So, again based on my experience if they had missed to leave you at -0.75 D then correction with laser would be easy, but not from the +0.75 D side.

This all said, if you are eyeglasses free and generally happy with the vision, you had a good outcome. May be best to just be thankful for what you got. That is what I have resolved to do.

I should add that you should not take my word for laser not being a being a good option. Many clinics offer a free consultation and will let you know what they can and cannot do, if they are ethical. I don't think there is much difference between PRK and Lasik in what they can do. PRK has no flap and is more stable if you engage in contact sports. It takes longer to recover from.
