Risk to eye from weekly disposable contact lenses?

I am on a week's trial of weekly disposable contact lenses (switching from gas permeables).

By strange coincidence (?) I have noticed over the last couple of days an area on my eye which is causing concern. It could be a floater or more seriously I wonder if it could be a slight tear to the retina or the beginnings of a retinal detachment. I already have lost the macula in my right eye through a retinal haemmorhage and worry about the other eye. Moreover I have a connective tissue disorder (Ehlers Danlos Syndrome) and have been told that the risk of vitreous detachment in my 40s is quite high (I am 43).

Worse, the issue seems to be on the good eye.

Anyway I have an appointment in the morning to see my optician and if necessary he says he will refer me immediately to a 24 hour opthalmology clinic where laser surgery facilities are available.

My question, then, concerns the lenses. Can they damage the eye in any way? Surely they could not affect the retina and if anything are better for the eye than hard gas permeables?

Re: Risk to eye from weekly disposable contact lenses?

I would just make the observation that, a one-week trial for someone who is already accustomed to gas permeable contacts, seems inadequate and unlikely to show anything other than whether or not you can adapt to them.
I also have a loss of central vision in one eye and tried daily, 15-day and monthly soft contacts in that eye over a period of three or four months. They were initially OK but I gradually found them more and more uncomfortable. Eventually, the hospital told me I had developed 'follicles' (yes, I thought they were hair roots) on the surface covered by the contacts and they told me to return to conventional glasses. I am still going through the process of finding out what sort of lenses I need.
Posterior vitreous detachment (PVD) is nothing to worry about, unless it has the complication that I suffered of incomplete detachment. It happens to most people eventually and most of them are unaware that they have it.
With the complication of your connective tissue disease, it's possible that your presenting symptoms are different to those of others but I would expect even the slightest tear in the retina to cause more dramatic effects than a floater - flashing lights, particularly in the dark.
Please bear in mind that opticians are not qualified to assess the medical status of your retina. If they see any abnormality, they should immediately advise you to see an ophthalmologist of your own choice - not one of their cronies with whom they may have an 'arrangement'.
I hope you get some satisfactory answers. Do let us know how it goes.

Re: Risk to eye from weekly disposable contact lenses?

Thanks TopGeek. I decided to present myself at the emergency eye clinic at the local general hospital for the best available care.

I was seen by a specialist who could find nothing untoward despite extensive slit lens examination of my dilated eyes.

He speculated that there may be some loose jelly there which had crept under a sac I( at least I think that's what he said) but there was no need to take any action at the moment. He did say that if I should see flashing lights I need to get back there asap.

Although I was a bit relieved that I did not need laser surgery, I can still see something going on. It seems to be in my bad eye but is a worry. It looks a bit like a floater or even a fresh retinal haemmorage (the cause of my lost central vision). Anyway I guess I have to trust the doctor.

Luckily I have my annual appointment with the top specialist in the area in three weeks so I guess I will just wait for that, barring further developments.

Meanwhile I will decide over the weekend what to do about my contact lenses.

Re: Risk to eye from weekly disposable contact lenses?

It's unlikely to be retinal haemorrhage as that would have been evident with slit lens examination. Sounds like you're in good hands so I hope nothing else comes up in the next 3 weeks.
