Non-Penetrating Glaucoma Surgery (non-penetrating deep sclerectomy) can be an effective alternative to traditional trabeculectomy. This procedure is basically a trabeculectomy with the final thin layer left intact. Since this final layer is maintained, fluid can be absorbed directly into the blood vessels versus getting to the space under the top of the conjunctival layer to be absorbed like traditional surgery. This procedure reduces the risk of creating too low of pressure in the eye (hypotony) as well as lowers the chances for infection. This procedure is not ideal for all patients requiring filtering surgery.

Success Rate

Results of Nonpenetrating Filtration surgery depends on numerous factors and can vary greatly. Certain physicians specialize in this procedure due to the fairly recent development of this procedure. While nonpenetrating techniques offer many safety advantages, these techniques also are challenging and take longer to perform. Because of the learning curve associated with nonpenetrating surgery, the surgeon's experience can significantly affect his or her success rate.
