Medical Forum / General / Vision / October 2005When to rinse RGP lenses?
Hi, I don't think my optometrist indicated clearly when I should rinse my RGPs with saline. My next visit to them will be in a week's time so I thought I'd ask here instead. Do I need to rinse after: 1) Rubbing it with cleaner (Boston Advance) 2) Removing them from the condition solution (Boston Advance) Thanks.  SignatureRegards, wK Based on my memories of wearing RGPs you shouldn't need to rinse them at all. Wash your hands thoroughly with an oil-free detergent-based cleanser, pop them right in. >Hi, > [quoted text clipped - 8 lines] > >Thanks. +++++++++++++ Reply to the list as I do not publish an email address to USENET. This practice has cut my spam by more than 95%. Of course, I did have to abandon a perfectly good email account... Depends on the solution (or multipurpose solution) that you are using. For stuff that requires rinsing before inserting into the eye the tip (usually the cap too) of the bottle will be red. For stuff that is OK to go in the eye the tip will be white or green. You should probably "rinse" just a touch after rubbing them before you drop them into case with disinfecting/storage solution. For example the Lobob cleaning/disinfecting/storage solution should not get into your eyes and has a red tip. Unique PH multipurpose solution has a white tip and you can take the lens directly from the solution to the eye. -Quick > Based on my memories of wearing RGPs you shouldn't need > to rinse them at all.

Maybe another way to frame the question is: is there any downside in always rinsing an RGP with saline solution before inserting it into the eye? In other words: even if you use a conditioning solution intended for direct-from-storage insertion, is that solution automatically better for comfort, etc., than saline? SignatureLive simply so that others may simply live >> Depends on the solution (or multipurpose solution) that >> you [quoted text clipped - 25 lines] > solution automatically better for comfort, etc., than > saline? Sure. I guess it could be. Unique PH is pretty viscous. I've never used a saline solution formulated for contacts so maybe my impression that it is close to water in viscosity is wrong. I have tried the clear care system on my RGPs. I was under the impression that the disk reacted with the hydrogen peroxide to convert it to saline solution. It was pretty thin. Could just be me. We're still working on fit. Apparently I have dry eyes and I have been using drops (Blink) every 2 to 4 hours for the most comfort. Going straight from the Unique PH is pretty much the same as putting drops on the lens before insertion. Going straight from Clear Care was not. I had to put drops on the lenses before insertion. By the way, my doc said that everybody seems to be divided on whether Clear Care is good (long term) for RGP materials or at least some of them). -Quick Here's the scoop on RGP lens care. (PS: the mostly applies to soft lenses as well and I tried to note that in the text.) There are a number of different plastics and some are more compatible with one brand of solution(s) than others. Some products can actually damage the lens. You should use the product that is recommended by the manufacturer. Oftentimes there are a number of good choices and sometimes there is only one. Hydrogen peroxide systems like ClearCare and AOSept can destroy certain plastics. (Not generally true for soft lenses, but certain alcohol-containing cleaning solutions can damage some soft lenses and destroy some RGP plastics.) Wetting solution as a product to apply to the lens prior to insertion is designed to increase surface wetting and decrease lid-lens interaction: to increase comfort. Some plastics almost *require* this step and others may perform better using plain saline as a final rinse. Cleaning solutions applied to the lens need to be rinsed off with water or saline. If the water is very hard or very soft, saline is preferred. Personally, I prefer saline to tap water whenever possible. (Tap water may not be used on soft lenses.) Multi-step care (cleaning/rinsing/storage in disinfection solution/rinsing and then wetting solution) is always preferable to multipurpose solution used in the no-rub mode. Adding digital cleaning by rubbing helps but is never as complete as using a separate cleaning solution. Multipurpose solution applied directly into the eye means you are dosing your eyeball with a heavily preserved cleaning and disinfecting product. Is that worth the convenience? Multi-step care certainly takes a little more time and attention. Some final step wetting solutions (eg: Optimum) have very little potential for chemical sensitivity compared to others. Unpreserved saline as a final rinse prior to insertion can reduce that near zero. Some RGP plastics do well with that and others do not. I hope that answers the issues in this discussion. One more thing: the lens case. Please clean that, too! And replace it often, especially when it appears unclean. --LB, O.D. >Hi, > [quoted text clipped - 8 lines] > >Thanks. You should consult with your CL fitter for specific instructions pertaining to your eyes and lenses. Most RGP wearers will be given these instructions... Always rinse (tap water or saline) after using the cleaning solution. Best time to clean is when you are done wearing for the day. Cover the lenses with fresh storage/conditioning solution for at least 4 hours. Wash hands with plain soap, dry with cotton towel (no fabric softener). Lenses can be inserted straight from the case. Clean the case with hot water and air dry at least once a week. Replace the case at least twice a year. There are additional steps required if you are using an enzyme cleaner.

I don't recommend it, of course. RGP lenses have a slick, non-wettable surface, which has certain advantages. |
