If you're noticing that this world isn't quite as crisp because it was best after your best surgical procedure, you're probably wondering yourself, can you do lasik more than once or are you just stuck going back to glasses? The particular short answer is yes, it is definitely absolutely possible to have a second procedure, often known as an "enhancement. " However, it's not really quite as easy as just popping back into the clinic for a quick touch-up. There are a few boxes you need to tick before the surgeon will agree to go back again in.
Most people who get LASIK enjoy decades of clear vision. It's among those life-changing things where you wake up plus can actually view the alarm clock. Yet the eye is a living body organ, and just such as the rest of the body, it shifts with time. Whether it's been one season or fifteen years since your initial surgery, wanting to fine-tune your eyesight is really a pretty common conversation in optometry offices these times.
Why might you require a 2nd round?
It's frustrating when you've already taken care of "permanent" vision correction only to find your self squinting at road signs again. Generally, if someone will be looking at whether these people can do LASIK more than once, it's due to some thing called regression . This particular is just the fancy way of saying your attention has slightly shifted back toward the original shape, or even perhaps it didn't quite hit the 20/20 mark the first time around.
Sometimes, the first healing process doesn't go exactly as planned. The body may over-heal or under-heal, leaving you with a tiny bit of leftover nearsightedness or astigmatism. Within other cases, it's just the natural progression of age group. Even though your LASIK was perfect, your eyes can nevertheless change independently of the surgery. It's not that the LASIK "wore off"—it's that will your eye chose to keep changing shape.
The big the catch: Cornea width
The greatest factor in identifying if you can go under the particular laser again will be your cornea thickness . Think of your cornea like a piece of wood you're sanding down. LASIK functions by reshaping that wooden to change just how light hits your own retina. If you've already had the significant quantity of tissue removed during your 1st surgery, there might not really be enough "wood" left to sand down a 2nd time without making the structure associated with the eye unstable.
Before any surgeon agrees to a second treatment, they're going in order to map your cornea which includes high-tech image resolution. They need to ensure that will after a 2nd pass, your cornea will still become thick enough to maintain its natural pressure and shape. If it gets too thin, you operate the risk of a condition called ectasia, which is essentially the cornea bulging outward—and trust me, you definitely don't need that.
Improvement vs. Retreatment: What's the difference?
People often make use of these terms interchangeably, but in the medical world, these people usually mean slightly different things. A good enhancement usually happens within the first year right after your initial surgical treatment. This is usually covered below your initial transaction plan or even a "vision for life" assurance that many clinics offer. It's for those cases where the particular first surgery obtained you close, yet not quite to the finish collection.
A retreatment , on the various other hand, is generally what happens many yrs later. Maybe you had LASIK within your 20s, and today you're in your 40s and seeing things are obtaining blurry again. In this stage, the surgeon has to evaluate your eye as if you were a brand-new patient, taking straight into account just how much you've aged and how your eye health provides shifted on the years.
How the 2nd surgery really works
If you do go for a second round, the process is slightly different than the first time. Throughout your first LASIK, the surgeon developed a "flap" within your cornea, folded it in return, used the laser, and after that put the flap back. With regard to a second treatment, they usually possess two options.
First, they may try to lift the initial flap . This might sound a bit crazy, but even years later, a skilled surgeon can usually find the advantage of that initial flap and lightly lift it once again. This is usually the favored method since it has the same fast recovery time as the first surgery.
If lifting the flap isn't a great idea—maybe because it's been too long or there's a risk of epithelial ingrowth—they might suggest PRK instead. PRK is like LASIK's older brother. There's no argument; they just treat the top of eye. It takes a little lengthier to heal and can be more uncomfortable for a few days, but it's frequently safer for those who have leaner corneas or these who've already got LASIK once.
Is it age group or do you just need more LASIK?
One thing to keep in mind is the particular "over 40" element. If you're hitting your 40s or 50s and seeing you can't examine your phone any longer, that's not often some thing LASIK can repair. That's presbyopia , which is basically the lens inside your own eye getting rigid. It occurs everyone, even those who got perfect vision their particular whole lives.
If you request your doctor "can you do LASIK more than once" because you can't see the menu at dinner, they will might tell you that another LASIK procedure won't really help. If so, you're looking at reading through glasses, or maybe something called monovision LASIK , where these people fix one eyesight for distance plus leave the some other for close-up work. It sounds weird, but your brain actually adjusts in order to it pretty well.
Risks to consider the particular second time about
No surgical procedure is without risk, and going back again for seconds will slightly increase the chances of certain side effects. Dry vision is usually the big a single. Almost everyone will get dry eyes for a few months after the first LASIK, but following a second method, that dryness can be more prolonged.
There's the slightly increased risk of epithelial ingrowth , which is when the cells from the surface of your own eye start increasing underneath the flap. It's treatable, but it's an extra headache you probably want in order to avoid when possible. This particular is why doctors are extremely picky regarding who they clear for any second round; they wish to make certain the reward far outweighs the potential for these annoying complications.
Alternatives to a 2nd LASIK
In case your doctor tells you that your corneas are too thin regarding more LASIK, don't panic. You aren't necessarily destined to wear thick glasses for the sleep of your life. Since I mentioned, PRK is the very common alternative for retreatments.
There are also ICL (Implantable Collamer Lenses) , which are like permanent contact lenses placed inside the eye. Or, when you're a bit older, you might look into Refractive Lens Swap (RLE) . This really is basically cataract surgical treatment before you have cataracts. They exchange out your natural lens for the high-tech artificial 1 that can appropriate your vision for the rest of your life. It's a bit more intrusive, but it's a "one and done" solution that handles both distance and reading vision.
The results
So, can you do LASIK more than once ? Yes, you can, provided your eyes are healthy and you possess enough corneal tissue left to play along with. It's about getting a very truthful conversation with an experienced surgeon who else isn't just attempting to sell you a procedure.
If you're noticing your vision shifting, the very first step is the comprehensive eye exam. It may turn out that you don't need surgery with all—maybe your eyes are just dry, or maybe you've reached that age group where reading glasses are inevitable. But if this is a genuine shift inside your prescription, a "touch-up" can be exactly exactly what you need in order to get back to that clear, easy vision you cherished to begin with. Just remember to be affected individual with the process and realistic regarding the results!
