Yes, 7 years, you didn't read wrongly. Ortho K has been around for a really really long time! That's why I'm really surprised that it has not become the next biggest thing just like braces were.
To understand what Ortho K is, it is basically your hard lens, but instead of wearing it in the day, you wear it at night. Of course, it functions differently from the normal hard lens. What Ortho K lens does is to shape your cornea at night, such that in the day when you take your lens out, your cornea is shaped in a way that allows you to have perfect/ near perfect vision.
Please pardon me for I'm not going to go into the science of it, I'm just going to talk about my own experience with it.
When I first started using the lens, I had a really hard time getting used to having to insert something into my eyes. Putting the lens at night used to be torture as I couldn't control my instinct to shut my eye when something comes so close to it. At the end of the routine, my eyes are read with tears all over my face. Thank god I got used to it. Now, it's simply a breeze.
Of course, you will definitely feel some discomfort in the first 2 weeks of wearing the lens. I mean, they are hard lens, not soft lens that can be designed to feel like you are wearing nothing. It's hard lens, so you are going to feel something. And, Ortho K lens are slightly bigger in circumference as compared to normal hard lens, because it needs to cover your cornea and shape it, duh! So you are going to feel it there even more so. So it's perfectly normal for your eyes to tear, and get red a little simply because it feels awkward to have something so obviously in your eye. As long as it doesn't hurt, and your eye isn't getting really red, you are perfectly fine. And of course, you will get used to this feeling, and your eyes will too, so no more redness and tearing after a couple of weeks.
Since it is something that you are putting into your eye, the care for the lenses are definitely tedious, at least at the beginning. You will need to add in extra time for washing your lenses and storing them properly. But just like how you get used to having to brush your teeth day and night, you will get used to this routine. What used to take me 10 minutes is now only taking me 5 minutes, or even lesser on good days.
To give an overview of the whole routine (updated):
- Night: putting on the lens
Rinse the lens with saline water --> put them on [yes it's that simple now]
- Day: taking them out
Use suction to take lens out of eyes --> rinse with water --> wash with cleanser --> store in a case using oxysept solution and pill
Sounds really easy right! It's really a matter of getting used to the whole routine.
Then, what are the pros and cons of using Ortho K lenses? Why did I not simply go for Lasik, saving me the whole trouble of having to wear lenses and care for them?
Well, firstly, there are cons to lasik. I'm not talking about the severe medical issues that could potentially occur. I'm simply talking about some minor disadvantages that people will need to get used to, like dry eyes (according to a friend who did lasik 3 years back). Yes, of course lasik is going to be really convenient, with (normally) little drawbacks that one can get used to.
But lasik is a permanent procedure, Ortho K is not. And aside from the medial issues that could arise, there is a potential for complications such as the surfacing of other issues that comes with aging or whatever.
So having worn Ortho K lenses for 7 years, I am all for continuing with this routine till one day Lasik becomes a norm, or some other technology comes up.
But why Ortho K instead of normal soft lenses then?
One big advantage Ortho K lenses have over soft lenses are that Ortho K lenses, or hard lenses in general, prevent your degree from going up. This is definitely very very important for people who find that their degree is rising while wearing spectacles/soft lenses.
Well, then why Ortho K instead of hard lenses?
Day contact lens users often complain about dryness in their eyes after a long day of wearing the lenses. Or, they can't wear the lenses when going into the water, so they need to put up with bad vision when doing activities in the water. Otherwise, there are some people like me that likes to rub their eyes.
Wearing Ortho K lenses means that I have perfect or near perfect vision in the day without anything on my eyes at all. Doesn't this sound perfect? No dry eyes to deal with, no bad vision to deal with, no water to fear, rub your eyes whenever you want (it's not good to, but you get what I mean).
And this is why I have been a loyal Ortho K lens user for 7 years. I recommend this to anyone that fits the criteria (basically as long as your degree is around 600 or less).
Some people fear the potential drawbacks or cons that Ortho K brings. Well, all the cons/potential issues are basically the same as with any type of contact lens, so I don't see why you will choose day lens over Ortho K.
Perhaps the idea of wearing something at night bothers you. You fear the lens moving to places in should not be at. Well, you really don't have to worry about that, because Ortho K lenses having a bigger circumference and needing to shape your cornea means that it fits snugly onto your eyes, at where it should be (covering the coloured part of your eye). Unless your eyeball rotates itself in the night, your lens won't move to places it shouldn't be at.
But if you have the habit to rubbing your eyes at night, well, then maybe you need to reconsider. I was able to made my subconscious mind aware of the fact that I can't touch my eye at night, so I have no problems with that at all. But if you do have this habit, then maybe Ortho K isn't safe for you. '
Otherwise, really consider Ortho K. It is so much better than the other type of contact lenses that are available on the market. And please if you are on spectacles, just get rid of it already, spectacles are bad for you. So inconvenient, exhausts my eyes and gives me headaches.
There are a few trustworthy places in Singapore that offers Ortho K, otherwise feel free to contact me for the Optometrist and shop I go to:)
