26 Services ( View All )


While a trabeculectomy was the most recognized solution for glaucoma for many years, advancements in the ocular industry have led to the development of a range of minimally invasive services to address the optical nerve and prevent the spread of the disease. At Focal Point Vision in San Antonio, TX, our board-certified ophthalmologists are pleased to offer the ExPRESS Shunt to individuals with glaucoma to control their intraocular pressure (IOP). Candidates who can benefit the most from this treatment are those who experienced no relief from eye drops and require more intense care.

What Are The Benefits Of The ExPRESS Shunt?

ExPRESS shunts offer an effective reduction in intraocular pressure (IOP) and control of glaucoma with several great benefits, including;

  • Effectively reduces IOP
  • Works when medicated eye drops don’t
  • Reduces need for medication
  • Procedure is fast and pain-free
  • Less risk of complications
  • Fewer follow-up visits
  • Removable


This device works to create a scleral channel to allow fluid to drain from the eye. To execute a procedure with the ExPRESS Shunt, we will properly position the eye to prevent blinking and apply anesthetic drops to make the process as comfortable as possible. Once you are fully numb, we will then create a small flap into the eye roughly 3mm in width. The ExPRESS Shunt device is then inserted through the opening and closed. 

What Should I Expect After the ExPRESS Shunt Procedure?

After your treatment is finished, we will apply a bandage contact lens and give you detailed healing instructions for you to follow, including avoiding strenuous activities for a few weeks. We will also likely schedule one or more follow-up appointments to monitor your progress and improvements. During this time at our San Antonio, TX facility we will monitor your intraocular pressure and make adjustments to the flap if necessary. As soon as you have fully healed, you should be able to notice a wonderful change in your vision and overall health. After recovery, your follow-up appointments at Focal Point Vision may occur about every three months.
