Kerasoft IC and K3 Trial

[rosemary johnson]

How fascinating! - and what fun!!!
Maybe we coudl try to organise a KC group group visit to see the historic contact lenses and related areas?
WOuld anyone be interested inthat?

I hope you now have found your "perfect partner" now Gareth. Watch out as you may forget they are in and go for a short nap forgetting you are wearing contacts or thinking it will be only a short shut eye (as I did).

Does anyone know the DK O2 transmission through for:

1) Kerasoft 3
2) for the Kerasoft IC
3) Soft K
4) the acuity lens

The top two I am mostly interested in

Dk Values as I understand them
1. Kerasoft 3 = 57 Fatt Units
2. Kerasoft IC ?= 57 Fatt Units. I understand that the Kerasoft IC is the same material as above only different lens design?Lynn will confirm.
3. Soft K lens = 29 Fatt Units
4. Acuity = RGP lens? Different options of Acuity 30,60 or 90 which is in fact the Dk of the lens material.I believe they also manufacture the Acuity Shephard design in other materials on request.
The information is accurate to the best of my knowledge and hope it helps.

Day 9 (Well it was on Sunday 28 Dec)

Been away a couple of days visiting friends and familly wearing lenses for 12 - 14 hours per day and doing things I normally would not do wearing RGP lenses (not in dull windy conditions anyway). Saturday I washed the car wearing the lenses and it was bitingly cold in the wind. Normally this would be a big no no with the dust that gets kicked up but not with the K3's.

I hope you now have found your "perfect partner" now Gareth. Watch out as you may forget they are in and go for a short nap forgetting you are wearing contacts or thinking it will be only a short shut eye (as I did).

Thanks pepepepe, I have actually fallen asleep for half hour or so wearing the K3's. Never slept in the RGP's, as soon as the eyes rolled back as you nod off in them was too painful and I would wake up in pain and streamming eyes. Nothing like that with the K3's and it was after quite a hefty Christmas dinner and the long walk we had afterwards. Woke up with perfect vision.

The eye chart I use is printed from this site and although not wholely accurate, the readings are consistent, the chart is in the same place and I stand with my back against the bathroom door, so I am comparing like with like each day. For accurate measurments those are from visits to Lynn or the hospital. Normally I would check vision before I get in the car as work is an hours motorway driving and again when I leave work. Otherwise I have my visual ques that inform me when I need to do something. My eyes are quite sensitive and the hospital accept that might be why have am experiencing lens problems despite the good quality of lens fit I have with RGP's.

On Sunday I ws driving for a couple of hours at night and the star effect was just the same as when I have RGP's in, at this point I had been wearng the lenses K3's for about 10 hours. The lenses are plenty large enough I don't see the edges like I do with the RGP's. When wearing rgp's, there is a tear pool on the outer edge of the lenses and when light hits I get two whit circles on the outer lower perifery of my vision which innitially was distracting but I was getting more used to it.

Personally with my dyslexia and mild light sensitivity I would prefer the lenses to be slighhtly tinted, but I can overcome this with some sunglasses the optician made for me. They are my old glasses with a plane lens that has a slight tint, just the people who know me think the KC is cured and I can wear glasses again!

A brief note on the car, it does get used, in June 2008 we did an 800 mole round trip to display the car for a long weekend at Euro Disney which we had a special invite to and am awaiting a call from a tv company who are making a classic car programm and want an RS3100 to feature At the moment the car is in hibernation with no plans to bring the car out until April, only if the film and TV company get want the car will it come out sooner.

That's enough for now, need to think about putting lenses in for day 10!

Gareth, well its looking good !

I am just thinking out loud on the following,

Did you say that one eye corrects ok with glasses before ? if so, do you think you could only need the Kersoft for just one eye and glasses for the other ? partly because you wear glasses now to have a tint anyway. May be you could have the best of both worlds at the same time, kind of ?

Day 10

vision much the same as other days but the right lens did start to go blurred and I could see the tears breaking up showing the lens surface had become greasy. Afetr a good clean and a rinse as was well again.

Day 11 (today)

So far no repeat of a greasy lens. by now in my RGP's they would be very uncomforatble and in desperate need of a long soak in protein remover. So far no feeling of lens irritation which with RGP's is the fist sign of protein build up plus the RGP's lenses would sratr to go a bit misty.


Rgerading glasses, yes the left eye can be corrected but last time I got just one lens for that eye and re-using old frames the lens came to £200 with no tint. With a tint and the level of correction put the cost to over £300. There are cheaper lenses, but with a plain lens in the right eye there would be a significant weight difference so the glasses don't sit straight. plus they only really work when looking straight ahead, if I moved me eyes only then everything gets distorted and motion sickness sets in. This is even worse in the right eye and that only brings me to the third line on the chart on a good day.

I am actually at the point where it is cheaper to have a second pair of tinted glasses and use contact lenses all the time.

[pepepepe]

My better eye is correctable with glasses. The Optican who done my refraction said that aspheric lenses build in correction through out the lens, with regular glasses the correction is put in to a small area in the middle of the lens. I did find asheric lenses did give a better veiw through them marginally more. To me with things like this, little things means a lot to me.

Thanks for the update Gareth, how are you cleaning you new K3 contacts, I was using a multi purpose solution, which is quite easy to use. Do you need to use protein remover at some time, or isn't it necessary for the softs ? I am not too sure as I never used my softs for a longer enough time to know.

Thanks Graeme for your post.

Here is the link to Acuity

http://www.acuity-lenses.co.uk/

So I take it that the Kerasoft IC is not a thicker lens to the K3 and has the same DK ? I could not find that info. on any of K3 sites

Aspheric lenses do nothing extra for me, they are fitted to my current glasses.

IXC is a very new lens and only just launched so probably nothing web based until some more work has been done on the trials. The lens does not feel any thicker to me.

I am using ReNu MPS solution from Baush & Lomb. I seledcted this because I use their RGP solutions and they are the solutions I reat=ct least to for the RGP's.

RGP's need protein remover at least once per week, been wearing the KX for nearly 2 weeks and no need for protein clenaer. Not worn them for the past two days because my dauhter has been unwell and my wife and I have shared the staying up all night, so much of the day has been spent catching up on sleep. I considered it unwise to sleep for more than an hour with lenses and on occassion the past coupe days I have managed to catch 3 hours sleep before being away for most the night with cat naps!.

She slept all night so I am back on the K3's again.

The feeling of overwearing soft lenses is much the same as the RGP's so I am making a big assumption the softs will be the same. So far I have yet to get the sensation of protein build up and I have worn this type of lens for a month before with no problems. We do look at this type of thing when we review the lens fit on a monthly basis. We now have until March before I need to go back to RGP's for the hospital and then I hope they will put me back to 6 monthly visits so I can try he lenses for longer uninterupted.

[pepepepe]

Thats the solution I used too (or was given to use), its easy to rub both sides of the lens with your index finger and then put them in the container with some of the solution for their next use, I found.

Anyway I hope you good luck for the rest of the trail

Day 22 (Saturday 10 January)

Its now been a full three weeks since I started with my latest set of K3 lenses and bar a couple days off lens wear as mentioned earlier everything is going well.

The past week at work has seen 90% of my day infront of a PC and I have averaged 15 hours lens wear over the past 7 days. To get this with RGP's I would reall be suffernig, less so if I had averaged 12 hours with RGP's, so softs give greater than 25% increase in lens wear time.

Unchanged is the vision change through the day, start at 6/6 in each and 6/5 binocular and after the 15 hours we are at 6/9 left and 6/6 right, binocular is at 6/6.

I have had a few headaches and I put this down to the amount of PC use and the fact that my new office has a low ceiling and spot lights. Sun glasses were an option but I wanted to see fi it was possible to adjust to the lights, next week I will be wearing the sunglasses when i am in the office.

Looking back at how KC is treated from first diagnosis and the problems people have I have come to the firm conclusion that rather optoms going straight in with RGP's the softer option should be the first. As a group we need to discuss this, the AGM in the spring would be a good discussion forum as would the regional groups because with the full weight of the group pushing the optoms they would have to seriously consider the use of soft lenses as an initial managemnent strategy for KC.
