Many people who have the desire for Lasik surgery are worried about getting it, because they also have glaucoma. They become concerned that they will damage their eyes through Lasik or that the procedure will make their glaucoma worse. While it is understandable that a person is worried about his or her eyesight and wants to protect it, many concerns about Lasik can be alleviated by talking to an eye doctor and having one's questions answered. By doing this, a patient can make the best and most informed decision, leading to the best outcome, whatever the decision is.

What is Glaucoma?

Glaucoma is an eye disease that causes a gradual loss of vision. It is generally caused by high intraocular pressure (the pressure inside the eye). However, it is important to remember that the thickness of a person's cornea and other factors can affect eye pressure. What is high to one person might not be high to another person, so checking it over time and watching carefully for any damage or risk factors is important. High intraocular pressure that is uncontrolled and not 'normal' for a person -- someone with thicker corneas, for example, will generally have higher eye pressure -- can cause a deterioration of the optic nerve. A person will notice that their peripheral vision becomes less and less, and eventually, if not treated, the person will be looking 'through a tunnel' before losing vision completely.

There is Good News

There is some good news on two fronts. First, glaucoma is treatable. Once vision is lost, it cannot be recovered. However, the vision that has not yet been lost can be saved through prescription medications that stop or drastically slow the progression of the disease. Second, there is no evidence that Lasik surgery either causes glaucoma or makes it worse. The Lasik procedure deals with the cornea of the eye, as opposed to dealing with the inside of the eye. Since the intraocular pressure is inside the eye, it is not affected by it. The only 'concern' is that the pressure in the eye after Lasik may read lower than it actually is, so an eye doctor should be made aware of this. Beyond that, however, there are no other concerns when it comes to Lasik and glaucoma.

The Lasik Procedure

The procedure that takes place during Lasik is a relatively simple one. The patient is given a sedative if needed, and anesthetic drops are placed in the eyes to numb them. The eye is held open with a gentle restraint and a flap is cut in the corner. Sometimes this is done with a blade, but more and more people are offering bladeless Lasik, meaning that the laser is used to cut the flap. After the flap is cut and folded back, the laser is used to reshape the inner layers of the cornea. When the laser is done, the corneal flap is put back into place and begins to heal almost immediately. Medicated eye drops are given to the patient to put in his or her eye, and specific after-care instructions are also given, so that the chance of any kind of complication will be reduced. The entire Lasik procedure takes about 15 minutes, and is considered to be extremely safe.

For more and more people, Lasik is becoming the option that they choose to correct their vision. It is much safer than it used to be, and there are fewer complications as well.

Recent studies indicate that laser eye surgery has now surpassed contact lenses for safety, which means more people will likely be getting the surgery. For example, for someone who has glaucoma, there is no need to worry about Lasik making it worse or causing any kind of problem.
