SLT treatment takes just a few minutes to perform. Prior to treatment, your ophthalmologist will administer eye drops in order to prepare the eye and provide mild anesthesia. Then, gentle pulses of SLT laser light are delivered through a specially designed microscope, known as a slit lamp. The entire process takes just a few minutes. When it’s complete, your ophthalmologist may treat your eye with anti-inflammatory eye drops. One to three days after the procedure, your intraocular pressure should drop significantly. And of course, your ophthalmologist will want to re-check the treated eye during periodic follow-up visits.
