Ok, here is the scoop. I actually participated in caring for patients in the Focus Night & Day study (FND), so I have a lot of experience with this lens.
A. It is an absolutely fabulous lens! Perhaps the best technology on the market .. and absolutely without apprehension the ONLY lens that I have EVER let any of my patients wear extended wear. Before this lens I was constantly battling with the EW junkies in their AV lenses.. UGH!!
B. Lets talk DK.... the higher the better.. Acuvue in the 20's , and FND in the 180's .. need I say more.
C. My Dear sweet 13 year old has been wearing the lens 30 day EW now for 1 year without complication, without myopic creep, without corneal swelling and without even the slightest trace of encroachment.
D. Some cool things I have observed with this lens:
1. Decreased Myopia after 6 months of wear.... this is due to an actual decrease in corneal edema secondary to the increase in O2 transmission. This seems to happen with both EW and DW pts.
2. The Rx on this lens may need to be up to -0.50 step higher than the empirical estimation of power...
3. I have had more teen male patients with complications (2 to be exact) than anyone. Actually those are the only 2 I've seen with any type of problem. It actually occured before the final fitting, so EW was D/C'd immed. in these 2. Not sure why males might make an interesting study.
4. No more problem with mucin balls.
5. CL abusers, GPC patients (obviously!), those with encroachment etc. should only wear this lens as a DW lens.
6. This is an excellent option for the peds patient who will not wear their rx. I treated a baby +5.00 with this lens. The parents were frustrated that the child who was also a CAET and needed strab surg. would not wear his Rx. The +5.00 took care of about 50% of the ET.. so it was nec. We trained mom and dad to use the CL and the baby did great!! Sucessful for a yr now!
7. The lens, which is great for dryness for some, can be slightly uncomfortable for a select few. CL awareness is likely in the first day, but generally goes away.
8. If using for DES, please use Clear Care!!
P.S. No, I dont work for Ciba, but gosh i love this product.
Working on testing the new AV advance on pts with DES (NOT EW LENS!!!, DK is 89, water is in the low 40's). Have had 6 successful fits, and 1 that saw halos and another that thought the lens was dry. I LOVE it when I wear it.
