Hi, it’s Dr Khanna – we are tackling questions relating to Presbyopia.
Our first question is, “Can Presbyopia be corrected?” The answer is yes, Presbyopia can be corrected. We can use glasses, contact lens to overcome the effects of presbyopia, but if you want to totally correct it, we have to do a surgical procedure.
“Can presbyopia be reversed?” Yes we can reverse the ageing eyes, by putting in presbyopia by putting in presbyopia implant inside the eye. And that’s why it answers the next question.
“Can presbyopia be cured?” Yes, presbyopia can be cured and ageing eyes can be reversed with ‘PIE’ which is acronym for ‘Presbyopia Implant in Eye’
“Can presbyopia correct myopia?” No, presbyopia cannot correct myopia, but myopia helps in deferring the onset of presbyopia. Because myopia means that a person is nearsighted, they can see near but not far, so they wear glasses to see far. But when they take the glasses off, they can see near. So when they become presbyopic, the nearsightedness helps them, but after some point in time, the help vanishes.
“Can presbyopia cause headaches? Can presbyopia cause dizziness?” The answer is yes, and I’ll give you examples of this engineer, who is working on small microchips, and because of presbyopia, he tries to be very focused, he developed so much headaches and dizziness… that he had already been referred to orthopedics, neck surgeons, neurologists, and the only thing that cured him was PIE, when we did Presbyopia implant in his eyes, then he was able to get natural vision, and his awkward sitting posture was eliminated.
“Can presbyopia cause blindness?” Blindness in the sense of you not being able to see near. So it will be blindness for near, if you don’t use glasses or contact lens. And that must have been the case in smaller villages, and third-world countries where they can’t afford glasses, they’re not able to see near. And it’s also a manifestation of more of the industrialized world. Because as farmers, you may not need a lot of near vision, you don’t read, you plough, you milk cows and you may not notice the loss of near vision as you would notice when you’re on the computers or reading all the time.
Can presbyopia improve? With some exercises you can get improvement in presbyopia, especially during the early part when the presbyopia first starts. Doing some exercises like closing one eye and forcing your eye to read, and then doing the same on both, and then opening and trying to focus in and trying to bring it in gradually, that can help. So I think that’s one of the advantages you can get, but if you are 60 years old and already wearing, there’s unlikely to be a dramatic improvement. But some people get improvement when they develop cataracts, and that’s on their second sight. Because when nuclear sclerotic cataracts do a lot, it acts like a magnifying lens and makes you near sighted, so a person can then read, which they were not able to read before.
“Will Lasic make presbyopia worse? Presbyopia has got no sighted around its fixed stage, Lasic is not going to make it worse, it can mask the presbyopia. So in a farsighted person, doing Lasic can improve your reading and defer presbyopia. Whereas in a myopic person, if you correct for a near sighted parson, next they might have a need for reading glasses.
“Will everybody get presbyopia? Yes, everybody sooner or later gets presbyopia.
“Will surgery help presbyopia?” Yes, surgery does help presbyopia, and we are going to get into the details of presbyopia implants in our next set of questions. After this one which says
“Will Lasic correct presbyopia?” Lasic cannot correct presbyopia it can counteract the effect of presbyopia. What I’m trying to say here is, Lasic works on the static corneal, whereas presbyopia is a problem of the dynamic lens. So Lasic cannot cure or reverse presbyopia, it can help mask the effect. So if somebody is farsighted and we do Lasic, then your vision can improve. Or if somebody is planar and we make we make one eye for reading called blendo mono-vision , then they can be free of readers. But it does not cure presbyopia. The only thing that cures presbyopia and reverses ageing eyes is ‘PIE’ or ‘Presbyopia Implant in Eye’
In our next set of questions and answers will be related to presbyopia implant procedures. Thank you and stay tuned.
