Marmer Medical Center : SEEING CLEARLY IN FLIGHT

You are on your final approach. The runway is clearly in sight. At this moment you glance down at your instrument panel and find that it?s just a wee bit fuzzy. You lean forward to get a closer look and find that this makes it even more difficult to see. You have been noticing changes like this since your 40th birthday, but have been overlooking them because you?ve only been considering these changes to be related to ?eye strain.? When looking at maps prior to planning your next flight, you have noticed that you have had to hold the map out somewhat further from you than in the past. In fact, on some occasions you have found yourself ?cheating? a bit with a hand magnifier for some of the finer details.

You begin discussing this topic with a number of your contemporaries and hear a myriad of ?solutions.? Reading glasses appear to be the most popular solution, but although they certainly provide easy viewing of reading material, it makes the instrument panel in the cockpit almost impossible to see. You have heard that some individuals resort to ?monovision? where one contact lens, if necessary, is used for distance, and the contact in the other eye is used for close work. While this once again helps with reading, it still does not help with the instrument panel, but most importantly contributes to a slight decrease in depth perception. This has not been recommended for pilots coming in for a landing.

Bifocal lenses would help both distance and near, but a blended bifocal or trifocal would be necessary to see distance, instrument panel and reading (far, intermediate, and near.) But what if you have found that you just can?t wear glasses or contact lenses, or at least prefer not to if at all possible? Many have been experiencing nearly perfect vision all their lives, but now after the age of 40, are recognizing that near projects are beginning to become more and more difficult without any optical aid whatsoever.

There is now a solution that can actually restore the natural ability to focus once again. The act of changing focus from distance to near is called accommodation. The prescription in the eye does not change, but the ability to allow the lens in the eye to see things clearly up close requires the use of the ?accommodating muscles? of the eye. A new surgical procedure can actually turn back this clock 25 years and allow you to do your close work like you used to be able to do, when you were much younger.

Because the natural lens continues to grow throughout life, it eventually (at around 40 years of age) comprises the ability of the ?muscles of accommodation? to function. By placing four tiny implants just beneath the surface of the white of the eye overlying these muscles, natural ?accommodation? is restored. This outpatient procedure is done under topical anesthetic where you do not have to be put to sleep or stay overnight in the hospital. It restores your natural ability to see at near. There are no patches needed for the eyes once the procedure is completed. Immediately after completing the surgery, you may be able to pick up a newspaper and read.

Not everyone is nearsighted (myopia), not everyone is farsighted (Hyperopia,) and not everyone has astigmatism?but everyone who lives beyond the age of 40 experiences presbyopia, the inability to see at near without additional optical assistance. Recent technology in refractive surgery in ophthalmology has allowed us to reduce or eliminate nearsightedness, farsightedness, and astigmatism. The last frontier is to ?cure? presbyopia. All methods of treating presbyopia?to date?are merely ?compensation.? If you wear reading glasses, bifocals or bifocal lenses, you still have the same problems at near when these are removed. If you wear ?monovision? contacts or undergo ?monovision? refractive surgery, only one eye is clear at near, and depth perception is decreased. Until this new procedure was developed, there was no ability to allow both eyes to see clearly both at a distance and at near without any additional assistance. This procedure takes you back to your days of high school when you could look at the blackboard and then look at your notes without any additional assistance.
The estimated duration of the effectiveness of this procedure is projected to be between 25 and 30 years. At that time, if necessary, it may be possible to repeat the procedure to provide additional effect.

So, if you?re coming in on your final approach and are starting to notice difficulties and have the runway clearly in sight, but are having trouble in seeing the instrument panel or you watch, then you may wish to consider pursuing information regarding a new technique called The Surgical Reversal of Presbyopia.
