Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To prove that external contact micropulse diode laser trabeculoplasty (EMDLT) can significantly lower intraocular pressure in cases of advanced open angle glaucoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Micropulse diode laser trabeculoplasty applied through a gonioscopy len has been shown to be effective in lower the pressure for patients with primary open angle glaucoma (POAG). We believe that applied externally, the contact diode micropulse laser will be effective in lowering intraocular pressure for patients with advance open angle glaucoma with minimal side effects
