Laser Trabeculoplasty: A Clear Path to Lower Eye Pressure

When working with laser trabeculoplasty, a laser‑based procedure that opens the eye’s drainage channels to reduce pressure. Also known as LTP, it is a key option for glaucoma and intraocular pressure management. The technique belongs to the broader field of ophthalmology, where precise lasers are used to address fluid‑flow problems in the eye. In simple terms, laser trabeculoplasty enables better outflow of aqueous humor, which directly lowers the pressure that damages the optic nerve. Two common variants are selective laser trabeculoplasty (SLT) and argon laser trabeculoplasty (ALT); both target the trabecular meshwork but differ in laser wavelength and tissue impact.

Why Choose Laser Trabeculoplasty Over Long‑Term Eye Drops?

Many patients start with prescription eye drops to control glaucoma, but drops require daily adherence and can cause irritation. Laser trabeculoplasty offers a procedure‑once‑and‑watch result, often decreasing the need for multiple medications. During SLT, a low‑energy laser delivers millions of tiny pulses to the drainage tissue, preserving surrounding cells while still stimulating remodeling. ALT uses a higher‑energy argon laser, creating tiny burns that also improve outflow but may carry a slightly higher risk of inflammation. Studies show SLT can lower intraocular pressure by 20‑30% on average, with effects lasting up to five years before a repeat may be needed. The decision between SLT and ALT depends on factors such as baseline pressure, angle anatomy, and prior response to drops. For patients who struggle with medication compliance or experience side effects, laser trabeculoplasty provides a practical alternative that can be performed in a clinic setting, usually within 15 minutes.

Safety and recovery are straightforward. Most people experience mild redness or discomfort that fades within a day, and vision typically remains stable. Follow‑up appointments monitor pressure and assess whether additional treatment, like a repeat laser session or re‑introduction of eye drops, is necessary. Cost‑effectiveness becomes clear when you compare the cumulative expense of lifelong medications to a one‑time laser procedure. While not a cure, laser trabeculoplasty significantly slows disease progression for many, giving patients more freedom and less daily hassle.
