 With the growing popularity of Corrective laser eye surgery in the last couple of years, so grows its use on a large scale in ophthalmology to treat various eye conditions. It is being used to treat diseases such as macular degeneration, glaucoma, presbyopia and diabetic retinopathy.
Glaucoma
Glaucoma is a condition where a higher intraocular pressure causes harm to the optic nerve. Types of corrective laser surgery used to lower this pressure and treat glaucoma include:
Trabeculoplasty Tissue from the eye structure that determines the flow of fluid (trabecular meshwork) is ablated with the use of a laser. This procedure causes an increased outflow from the eye and is used for patients suffering from open-angle glaucoma.
Iridotomy The tissue from the iris is ablated using a laser. This type of corrective laser eye surgery is used to treat closed-angle glaucoma.
Cyclophotocoagulation The ciliary tissue is ablated using a laser. This is used to treat patients who have not respond to other surgical procedures.
Macular Degeneration
Macular degeneration involves an abnormal growth of blood vessels that causes vision loss,
generally associated with old age. If discovered early, it can be treated using corrective laser eye surgery. The disease will not be cured, but this type of treatment can prevent future vision loss. There are two types of treatments used for this eye condition:
Laser surgery involves using a laser to damage new blood vessels that appear in the eye.
Photodynamic Therapy (PDT) A photoactive medicine is used together with the laser treatment to damage new blood vessels. The medicine is injected into the blood and then activated through corrective laser eye surgery, proving very effective in destroying blood vessels. However, several sessions might be needed to get the desired effects.
Diabetic Retinopathy
Diabetic retinopathy also involves an abnormal growth of blood vessels, as well as damaged blood vessels. Generally, it can be prevented, or at least delayed, with a good diabetes treatment. However, if this disease develops, it can be treated with laser photocoagulation. This procedure seals leaking blood vessels and slows down the process of abnormal blood vessel growth.
Presbyopia
This eye condition, also related to age, is where the eye loses its flexibility and ability to focus on close objects. Monovision corrective laser eye surgery is used to treat this disease. This procedure corrects one eye for close vision and the other for distance vision. This type of corrective laser eye surgery is irreversible, so patients are often advised to try it out with contact lenses first to see if the eyes adjust properly.
There are other eye conditions that can be treated with corrective laser eye surgery too. For more in-depth information these eye diseases, what procedures can be used, and whether you are a good candidate, it is best to talk to a doctor.
