LASIK surgery or laser-assisted in situ keratomileusis surgery is a refractive surgery for vision correction. Most often, you get freedom from eyeglasses or contact lenses after this. The conditions that can be corrected are farsightedness, nearsightedness, astigmatism (cornea with uneven curves) and presbyopia (inability to focus sharply on objects).
Refractive surgery involves reshaping of the cornea, which enhances the ability of the eyes to focus. While the need for vision aids is completely eliminated in some people, others may still need glasses for reading or night driving.
Contrary to the perception that refractive surgeries are new, they have been in practice for over 100 years with huge advances in techniques over the last three decades. Advanced techniques were first used in the late 1970s and the first laser-assisted surgery in early 1990. Remember that LASIK surgery in Detroit is one of the most popular vision-correction surgeries.
Use of laser in LASIK surgery
The word laser often generates fear when we think of LASIK Detroit option. With advancement in technology, this fear is actually baseless. The excimer laser used is controlled by a computer. This enables the surgeons to remove precisely the amount of corneal tissue that is necessary. The degree of safety with this procedure is very high.
The actual procedure
The steps involved in LASIK surgery are as below:
Before the surgery is begun, the eye is numbed to take care of the pain using eye drops.
To prevent blinking of the eyes during surgery, an eye holder is employed.
In order to lift and flatten the corneal structure, and prevent the eye from moving, a suction ring is used over the eye.
Using the appropriate instrument, an eye flap is created in the cornea. This flap is then folded, revealing the midsection of the cornea called the stroma.
Laser is now used to sculpt the corneal tissue that is exposed.
The flap is then placed back in its original position. No sutures are used as the flap attaches itself within a matter of a few minutes.
Eye drops that help in healing are now placed.
After the procedure
It is normal to feel a bit of itching or burning of the eyes. This most often does not last more than a day. Rubbing of the eyes must be strictly avoided as you risk moving the flap by doing this. Although it takes about 3-6 months for the vision to completely stabilize, improvements in vision can be seen as early as the first day after the operation.
