Lasik stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. Lasik is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. If you are thinking about undergoing an eye surgery, think about Lasik eye surgery. Make sure you review all your options with an experienced eye professional. Every type of surgery should be considered serious. You always should understand both the benefits and the risks of the surgery.
Lasik surgery carefully removes the corneal tissue with a laser and this gentle laser then reshapes the cornea itself. This action in turn adjustments and strengthens the power of cornea has to focus on objects far and near. This type of surgery is more commonly known as refractive surgery. There are many types of eye surgeries that can be performed today to increase your vision strength. The most common other two types of surgery include radial keratotomy and photorefractive keratectomy. These two surgeries are also aimed at reshape the cornea, but using different techniques to do so.
Lasik surgery can be done with a laser or with a small knife. The radial keratotomy is the type of eye surgery that uses this small knife. The small knife is used to make several slits in the cornea these few small slits change the shape and the focus of your cornea. These two types of surgery are very effective. Of course your eye will be incredibly sensitive following a surgery of this kind, but this is to be expected. You may feel slight irritation concerning your eye as well. These irritations are mild and a simple pain reliever will ease your pain. These symptoms are only directly following your Lasik surgery.
Most patients are very pleased with the results of their refractive surgery. However, like any other medical procedure, there are risks involved. That's why it is important for you to understand the limitations and possible complications of refractive surgery.
If you decide to go ahead with Lasik surgery, you will need an initial or baseline evaluation by your eye doctor to determine if you are a good candidate. If you wear contact lenses, it is a good idea to stop wearing them before your baseline evaluation and switch to wearing your glasses full-time. Not leaving your contact lenses out long enough for your cornea to assume its natural shape before surgery can have negative consequences. The consequences include inaccurate measurements and can lead to a poor surgical plan, resulting in poor vision after surgery. The measurements may need to be repeated at least a week after your first evaluation and before surgery to make sure they have not changed. This is very important if you wear RGP or hard lenses.
