Several different laser treatments exist for the treatment of glaucoma. Different lasers omit laser light with different propertiesare used to perform these various laser treatments.
Besides the laser treatment described above, there are other laser treatments that can be used in specific situations, such as closed-angle glaucoma, as well as other kinds of glaucoma. What is common to all these laser treatments is that they are performed in the clinic following gentle anesthesia achieved using numbing eye-drops, with almost no pain felt during the actual laser session. The patient can usually return home after an hour or two and almost immediately resume full activity (including going to work the following day).
These laser treatments treat the inside of the eye without necessitating invasive surgery, nor surgical entry into the eye, and without requiring the sterile conditions of an operating room.
The question arises: which patients are suited for laser surgery and which for an operation? The answer is that the decision is, indeed, not an easy one and usually can only be made after a thorough examination of the patient by the doctor who performs such surgeries. Numerous factors are used to establish a treatment decision. Consequently, a treatment plan is designed for each patient based on the type of glaucoma, the intra-ocular pressure values, the structure of the eye, as well as specific findings on eye examination, the severity of damage to the optic nerve and the visual field, the patient’s age and a wide range of additional factors (such as the existence of additional diseases in the eye, the condition of the lens (is there a cataract), diabetes and the appearance and function of the area of the eye responsible for drainage).
In summary: laser treatments, are used routinely for the treatment of glaucoma, and have been in existence for over 40 years. With time they have constantly evolved into sophisticated treatment modalities that greatly improve our ability to control glaucoma, and occasionally fix limitations in eye structure that would otherwise lead to exacerbation of glaucoma had they not been corrected. An explanation about the type of treatment that you have may alleviate many fears, and the knowledge that the procedure will be carried out by an expert doctor with experience ensures the best chance for maximal success of the procedure.
