Laser in-situ keratomileusis surgery, or LASIK in short, is extremely popular amongst nearsighted and farsighted individuals for vision correction. In fact, this type of surgery is also useful for those having astigmatism. Here, the cornea or the clear front portion of the eye is reshaped so that it can direct the light travelling through it to the retina, which is located in the back of the eye.
During the lasik surgery, a femtosecond or microkeratome laser is used for cutting out a thin flap in the cornea. The flap is then peeled back in order to reveal the corneal tissue lying beneath it. The surgeon then proceeds to reshape the cornea to allow better focusing of the light onto the retina. After the cornea has been reshaped to the surgeon’s liking, the flap is put back in place and the surgery ends.
One of the top reasons why this type of surgery is so popular is its effectiveness. About 96% of the patients who have undergone LASIK eye surgery have received their desired vision post surgery. Moreover, the correction in vision is experienced almost immediately or one day after the surgery.
After undergoing LASIK eye surgery, individuals experience a dramatic reduction in the need for contact lenses or spectacles/glasses. In fact, most people stop being dependent on these for a clear vision after the surgery. Another reason to opt for this type of surgery is that there are no stitches or bandages involved; also, one does not experience any pain during the surgery due to the use of numbing drops prior to the operation. Of course, one would experience mild discomfort after one or two days of the surgery but the pain is not intolerable.
Before you try to find the best LASIK surgeon in your vicinity and sign up for the operation, it is advisable to do some research in order to educate yourself about what you can expect when you go in for this type of surgery. First things first, keep in mind that some patients may experience side effects after the surgery, although this is quite rare. Some of the potential side effects are dry eyes, seeing halo around images, fluctuating vision, glare and so on.
The surgeons generally evaluate the medical history of the patient before preparing to conduct the surgery. There are also some tests that have to be conducted initially in order to measure the air pressure, pupil dilation, corneal mapping, refraction and corneal thickness. After these tests are done, you can speak to your surgeon and schedule an appointment for the surgery.
