Silicon intraocular lens

I read the opposite, that acrylic lens have more issues.

The various issues depend on the material, whether a lens edge is square or rounded, the diameter of the lens etc. There are some compromises associated with all the choices. So, one can't just look at a lens material and say that because of that, the particular lens is the best.

What is the most forgiving model of silicone lens for positive dysphotopsia? Some idea?

(I mean low refractive index, 6 mm optic, rounded one or both edges, biconvex optics, anti-glare coating)

Steve, just wondering how the silicone lens is now.  Did the flickering and glare go away?  Did you have the YAG for the PCO?  I was told that silicone is better for dysphotopsia and I am considering a lens exchange from acrylic to silicone.

ESA...thanks for asking.  Yes YAG was done Mid December and it helped with big starbursts.  Single point light Halo and florescent light glare remain a problem.

I asked a dozen times (before YAG) if I should replace lens with acrylic and surgeon and my optometrist both said no.  Comment was way to much risk and that my Z9002 lenses are very good lenses. 

My theory is that the Z9002 lenses are too shiny/glossy - bouncing light around, and or my very little astigmatism is causing glare.

I plan to get PRK in about a month.  TBD..

Steve, is your lens a monofocal lens?  I am suprised a silicone lens has so much glare. I was told by doctors that silicone is more forgiving with the glare.  What is the reason for the PRK?  

I have single vision +13.0 IOLs in both eyes, both silicone lenses.  Non toric.  So yes single vision lenses. 

PRK is to adjust for lenses being over corrected.  My distance vision needs a +.75 correction due to Dr screwing up Rx.  Despite asking to measure twice/cut once he said no need. I should have insisted.

 

Even if you decide to go with PRK for your eye, you may want to consult with a LASIK surgeon as a comparison. Both procedures do the same thing with similar results, but the recovery from LASIK is quicker. There is some advantage of having PRK done if one is still playing contact sports, but that may not be important to you.

Thanks AT....I see Surgeon tomorrow.  I'll ask again re PRK vs Lasik.  I will also ask my regular Optometrist and another surgeon.

Was it over corrected with too much near vision?  What is your distance vision now?

Hi ESA..  No it was over corrected to be far sighted. NOT GOOD.  It made nearsighted very bad and mid distance also not good.  Distance during day was fair, but I had to get +.75 lenses to bring distance back to "better".  Of course I need readers +2.25 for close up.

Since then I have had PRK to correct.  That was 5 weeks ago and my vision is way more comfortable.  I would guess right now I am about -.5L and -.25R near sighted.  Surgeon says it will be several more months for vision to settle in.  He is expecting plano for distance!  I am enjoying mid distance vision, however my golf ball still goes out of sight at about 100 yards! 

Did you have the PRK in both eyes?  Which one was over corrected? If you have Plano, won’t that make your reading and intermediate still a bit fuzzy?  

Both eyes were over corrected with IOLs.  So yes both eyes had PRK. 

Yes reading will always need correction with readers or progressive glasses. 

I choose both eyes set to distance for golf, skiing, biking, with good depth perception.

My surgeon would not do Lasik on my eyes...plenty of cornea, just said it usually is more

accurate.  Plus allows for easier future laser surgery.

Thanks for sharing the info. Now we know there is another option, PRK, other than the laser enhancements.

Actually PRK is a laser enhancement.  Differs from Lasik in that Cornea is not sliced.  Read about the two a bit more. Do search on Lasik vs PRK.     

Your correction is much appreciate.  Will read up more.  Thanks.
