Clinical Trial Summary

Direct Selective Laser Trabeculoplasty (DSLT) is an emerging therapeutic technology to treat glaucoma. DSLT was previously tested in 2 clinical trials and demonstrated promising safety and efficacy results in reducing the patient's intra ocular pressure. Experience gained in the previous clinical studies indicates that a full exposure of the limbal area may be a challenge in patients with narrow palpebral fissures, narrow or floppy eyelids, and patients with deep-set eyes.

Description:

The DSLT procedure is carried out in the doctor's office while the patient sits in front of the DSLT device (termed the "Eagle" device) for couple of minutes. In this procedure, 120 laser applications are performed around the full circumference of the ocular limbus, after the system automatically recognizes the limbal target area. It is therefore essential that a full exposure of 3600 limbal area will be achieved, and this is done by placing an eye lid retractor (speculum) in the treated eye at the beginning of the procedure. The purpose of this study is to evaluate the compatibility of different types of lid retractors. The lid retractors will be tested in adult volunteers visiting the study eye clinic for any reason.
