Laser Treatments

Medications and eye drops are oftentimes the first line of defense against elevated eye pressures, but undesirable side effects or simply the inability to control the glaucoma with medications may lead to laser therapy as a better alternative. We commonly perform SLT and YAG PI procedures at Minnesota Eye Consultants, depending on your needs.


Selective Laser Trabeculoplasty (SLT) is an advanced type of laser treatment to help you manage your open-angle glaucoma. The SLT selectively stimulates or changes specific pigmented cells to activate increased drainage of the aqueous humor. This gentle technique produces lower eye pressure without damaging other tissues and doesn’t have any adverse scarring effects. For this reason, the SLT may potentially be repeated if needed.

Laser Peripheral Iridotomy (YAG PI)

The treatment for angle-closure glaucoma, or narrow-angle glaucoma, is generally initiated with Laser Peripheral Iridotomy (YAG PI) to open the drainage channels of the eye. The narrow angle is widened as the laser creates a hole towards the outer edge of the iris, allowing more fluid to exit.
