Glaucoma

Glaucoma is a leading cause of blindness and visual impairment in the United States. Glaucoma, known as the "sneak thief of sight," can affect patients of all ages. Many people affected with glaucoma do not experience any symptoms and may not be aware that they have the disease until they have lost a significant amount of vision. With early detection and treatment, eyes can be protected against the serious loss of vision or blindness.

Glaucoma can affect anyone from newborn infants to the elderly. It has been estimated that up to 3 million Americans have glaucoma. At least half of those people do not know they have glaucoma because it usually has no symptoms.

Types of Glaucoma

There are several types of glaucoma with two main types: open-angle and angle-closure.

Open-Angle Glaucoma

Open-angle glaucoma is the most common type of glaucoma where the fluid in the eye drains too slowly through the network of tiny drainage channels, known as the trabecula. The pressure in the eye increases as the fluid in the eye continues to build. Loss of vision occurs gradually and the vision loss is not always noticed until it becomes irreversible. About 95 percent of glaucoma cases are due to open-angle glaucoma.

Treatment of Glaucoma

Once glaucoma has been diagnosed, treatment should begin as soon as possible to help minimize the risk of permanent vision loss. There is no cure for glaucoma, so treatment focuses on relieving symptoms and preventing further damage. Treatment for each individual case depends on the type and severity of the glaucoma. Some of the treatment methods for glaucoma are:

Medication

Eye drops or oral medication may be used to either reduce fluid production in the front of the eye or to help drain excess fluid. Side effects of the medication may result in redness, stinging, irritation or blurry vision. While glaucoma often has no symptoms, regular use of the medication is needed to keep the eye pressure under control.

Laser Surgery

Trabeculoplasty, iridotomy or cyclophotocoagulation are laser procedures that aim to increase the outflow of fluid from the eye or eliminate fluid blockages.

Surgery

Surgery may be performed after medication and laser procedures have been unsuccessful. There are two types of surgery; canaloplasty and trabeculectomy.  Canaloplasty is an advanced surgical  treatment of glaucoma using microcatheter technology to enlarge the eyes natural drainage system. Trabeculectomy may be performed to create a new channel to drain fluid from the eye and reduce the pressure that causes glaucoma.

Cataracts

Cataract surgery is a minimally invasive procedure that is typically performed on an outpatient basis using local anesthesia. Cataract surgery replaces the cloudy natural lens of the eye with a clear artificial lens, known as an intraocular lens (IOL). Cataracts affect more than half of all Americans age 60 and older causing a progressive, painless loss of vision, as well as:

  • Blurry or hazy vision
  • Spots in front of the eyes
  • Sensitivity to glare
  • A filmy feeling over the eye

  • A temporary improvement in near vision
  • Double vision
  • Poor night time vision
  • Vision that has a yellow tinge

Our doctors perform a minimally invasive, small-incision, no-stitch cataract surgery called phacoemulsification, also known as phaco, surgery. During this procedure, a tiny incision is made in the eye making room for a small ultrasonic probe. This probe breaks up, or emulsifies, the cloudy lens into tiny pieces. The lens pieces are then suctioned out through the probe. Because of its small size, the incision will be able to heal on its own with only a topical eye drop, so there are no injections or stitching in the eye at all.

After the cloudy lens has been removed, the artificial IOL is implanted in the eye. The IOL is inserted through the same small incision that was made to remove the original lens. This process significantly reduces recovery time while reducing the risk of bleeding, scarring, irritation and distortion.

Laser Cataract Surgery

The Eye Center of Indiana is proud to offer an advanced laser cataract procedure, a new technology used to safely remove cataracts and restore vision.  The LENSAR Laser Cataract System is designed specifically for cataract surgery.  It combines high resolution 3D imaging with an advanced femtosecond laser.  The 3D image gives the surgeon a fully automated reconstruction of the cornea and lens surfaces, and works with the laser to deliver precise laser pulse placement and surgical incisions.  LENSAR’s precision, 3D imaging, and laser incisions help the surgeon to ensure that the cataract is safely removed and that the new intraocular lens is perfectly placed, resulting in better visual outcomes.  The femtosecond laser, along with the skill of the surgeon, promises more precise surgery that can lead to improved outcomes as part of an advanced technology treatment plan with the goal of reducing dependency on glasses after cataract surgery.
