Read About the Benefits and drawbacks of Lasic Surgery
As we get older, the flexibility of the natural eye lens to alter its shape and power to look at far or minute 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 aid of Lasic surgery. It does not improve the ability of the lens to alter shape or enhance the power of the lens. Instead, it makes certain structural changes of the lens to be able to do away with the need for visual aids.
The word Lasic implies the use of laser rays beneath the corneal flap to enhance the shape of the cornea so as to correct defects in vision. 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 fixed pattern.
3.Replacing the corneal flap back into position.
Though the procedure sounds to be really useful and easy, it has a few drawbacks. Below are some advantages and disadvantages of the procedure.
Benefits of Lasic surgery:
1.It is a very quick procedure that takes less than half an hour. There won’t be any stitches or bandages.
2.It eliminates the requirement for spectacles 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 must be done by an experienced eye surgeon.
5.Like other surgeries, hospitalization is not needed. The patients could drive home on their own within one or two hours after the surgery. Therefore there won’t be any disruption to the daily work.
Disadvantages of Lasic surgery:
1.The changes made to the structure of the cornea are permanent.
2.The need for reading glasses could arise in future.
3.Some individuals 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 might bring about 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 a whole lot worse.
5.This is a very expensive surgery. Several insurance companies do not provide coverage for lasic. Therefore, seek advice from your insurance provider before undergoing the surgery.
6.In a few cases, other surgeries may have to be performed to get the complete results of lasic surgery. In a few other cases, lasicmay have to be repeated for better results.
7.Post-operative care is extremely important 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 cons of lasic surgery, it is vital to discuss with the surgeon to know the actual cause for poor vision and decide if lasic can improve the vision. To lessen the risk of post operative complications, do detailed research and get the surgery done by an experienced eye surgeon with many positive reviews.
Lasic surgery is one of the modern gifts of medical science. However, there are many questions that arise in the minds of people who go for this surgery. You can learn more about this surgery by following the link.
