question on contact lenses and olive oil

Hi:

I just had salad dressing splash a small amount on my eye while wearing
contacts. Is the lense going to be ruined or will it just be washed
off when I clean them?

Any answers are welcome. I love my contacts and can't affort to keep
replacing them.

Thanks

Clean the lens with an alcohol based cleaner like Miraflow or Pliagel.
This will remove the oil.

Thanks much. I haven't been using that stuff. I have been using the
no rub cleaners. Would that do the same job?

Thanks

no. alcohol based cleaners can clean oil-based organic material better
than no-rub cleaners. no-rub cleaners aren't very effective cleaning
solutions but they are "good enough" for disposable contacts.

What do you think of Optima ESC? And will this
take care of most everything?

I use that to rub my XO(?) RGPs at night, rinse
with tap water and soak in Unique PH overnight
to sterilize. Seems that I get crud on my lenses
from my eyes so I use the ESC every night.

I couldn't tell you about that, but I now have changed to 1 step
solutions for RGP's due to the prevalence of acanthamoeba, especially
as many of my patients are on tank water.

I use Menicon Menicare and Progent monthly, the Progent eliminates
everything from the lens surface, better than polishing.

Catman X:

You said that the alcohol based cleaner will work on the olive oil. Do
you mean on soft lenses or RGPs. I have soft lenses?

Thanks

For Dr. Grant:

FYI, doc: Here in the USA, Miraflow contains alcohol and Pliagel, the
same surfactant, does not. Also Progent is not available to patients,
only practitioners for in-office use. Menicare is likewise unavailable
to patients.

PS: Do you have any experience with the Menifocal RGP? It's not
available here, but perhaps soon.

For Stew:

Miraflow is fine for your soft lenses with two little exceptions: If
it's made Proclear's omafilcon material or hioxifilcon A material, limit
contact time with the cleaner to 10 seconds and rinse thoroughly with
saline or you could damage the lens. (If you notice the lens shriveling
up, you've been there too long!)

LB, O.D.

Yes soft lenses.

FYI-

Received on 12/20/05 from Kaz Murakami, President, Menicon America:

====
We plan to conduct a test marketing of the Menifocal Z at limited
doctor sites in the Q2-3 of 2006 in the US and, then, we expect to
launch it officially late next year.

I'm interested. The docs in Aus reported some good things:

====

Clinical Vision Research Australia (CL, SAG, CAW), Victorian College
of Optometry, and Department of Optometry and Vision Sciences (CL,
CAW), University of Melbourne, Melbourne, Australia.


PURPOSE.: The Menifocal Z is an alternating vision, concentric,
bifocal gas-permeable (GP) contact lens; center distance is connected
to near periphery by a smooth transition zone. The lens is produced
using tisilfocon A (Menicon Z material), which is approved for up to
30 days of continuous wear (CW). The aim of this study was to evaluate
the clinical performance of the Menifocal Z when worn for up to 30
days of CW for 6 months.

METHODS.: Thirty-five existing GP lens wearers were enrolled in the
study. Subjects were fitted with Menifocal Z lenses and follow-up
visits were conducted after 2 weeks of daily wear and 1 day, 1 week, 6
weeks, 3 and 6 months of CW. A range of objective and subjective
clinical performance measures were assessed, including distance and
near visual acuity, the physiological response to CW, and subjective
evaluation of vision and comfort.

RESULTS.: Twenty-seven subjects (77%) completed the study and eight
(23%) discontinued: five (14%) as a result of lens-related problems
(four vision, one comfort) and three (9%) as a result of non-lens
related reasons. Average CW time achieved by the subjects was 22 +/- 2
days. Mean binocular logarithm of the minimum angle of resolution
(logMAR) acuities at 6 months were: high contrast distance 0.03
(20/20-), low contrast distance 0.63 (20/80-), and high contrast near
0.26 (20/25, N4). Adverse responses and lens binding were minimal, and
there were no significant increases in corneal staining, corneal
vascularization, or superior palpebral conjunctival papillae over time
(p > 0.05). Problems with night vision (distance and near) with the
lenses were the most common difficulties reported by the subjects.

CONCLUSIONS.: The Menifocal Z appears to be a promising option for
presbyopic vision correction, providing successful correction of
distance and near vision in a group of experienced GP lens wearers.
The hyper Dk tisilfocon A (Menicon Z) material allowed for safe wear
of the lenses on a CW basis.
