The Effect of Trabeculectomy & Ex-PRESS Glaucoma Drainage Implant on the Corneal Biomechanical Properties
This study aims to look into the change of the corneal biomechanical properties in patients undergoing insertion of the Ex-PRESS mini shunt or trabeculectomy for medically uncontrolled glaucoma
The patients in the study were divided into two groups. In group 1 the patients had the Ex-PRESS mini shunt inserted in the operated eye and in group 2 the patients underwent standard trabeculectomy.
The corneal biomechanical properties were measured with the Ocular Response Analyzer before surgery and at 1, 6 and 12 months after surgery. The corneal biomechanical properties measured were the Corneal Hysteresis (CH) and the Corneal Resistance Factor (CRF).
The change of the CH and CRF was compared in each group before and after surgery (at the aforementioned predetermined time points) and between the two groups.
The intraocular pressure was also measured with the Goldmann applanation tonometer at the same time points and the change was compared before and after surgery in each group and between the two groups.
