Know About The Advantages And Disadvantages Of Lasic Surgery
As we age, the ability of the natural eye lens to alter its shape and power to look at far or very small objects reduces
. This change can be overcome by using reading glasses or bifocals. However, the problem of poor vision can be overcome very easily with the help of Lasic surgery. It does not improve the ability of the lens to change shape or improve the power of the lens. Instead, it makes certain structural changes of the lens so as to eliminate the need for visual aids.
The term Lasic implies the use of laser rays underneath the corneal flap to improve the shape of the cornea so as to correct defects in eyesight. In Medical terms, it is referred to as Lasic insitu keratomileuesis. The procedure involves three steps:
1. Removing the thin corneal flap by making a small incision.
2. Reshaping the cornea to a predetermined pattern.
3. Replacing the corneal flap back into position.
Though the procedure sounds to be very advantageous and simple, it has certain disadvantages. What follows is a list of advantages and disadvantages of the procedure.
Advantages of Lasic surgery:
1. It is a very short procedure that takes less than half an hour. There will be no stitches or bandages.
2. It eliminates the need for eyeglasses or contacts.
3. When compared to refractive surgery, the risk of visual impairment is much less through lasic.
4. The technique has a high success rate. But it should be done by an experienced eye surgeon.
5. Like other surgeries, hospitalization is not required. The patients can drive home on their own within one or two hours after the surgery. So there will be no disturbance to the regular work.
Disadvantages of Lasic surgery:
1. The changes made to the structure of the cornea are irreversible.
2. The need for reading glasses may arise in future.
3. Some people may suffer with dry eyes, increased light sensitivity and double vision after undergoing the surgery.
4. If the surgery is done without having made perfect calculations, it may result in under- or over-corrections in the shape of the cornea. This, in turn, results in additional vision problems. In certain cases, the actual problem may become even worse.
5. This is a very expensive surgery. Many insurance companies do not offer coverage for lasic. Hence, check with your insurance provider before undergoing the surgery.
6. In certain cases, other surgeries may have to be performed to obtain the complete results of lasic surgery. In some other cases, lasic may have to be repeated for better results.
7. Post-operative care is highly essential for several months after undergoing the surgery.
8. Some people may suffer with glared vision or the presence of a halo around all the objects.
In view of the disadvantages of lasic surgery, it is essential to discuss with the doctor to find the actual cause for poor vision and decide if lasic can improve the vision. To reduce the risk of post operative complications, do thorough research and get the surgery done by an experienced eye surgeon with a great number of positive reviews.
