Endocyclophotocoagulation (ECP)®

Endocyclophotocoagulation (ECP) is a well-established minimally invasive glaucoma surgery (MIGS) that has been safely performed since 1992. This advanced laser procedure lowers intraocular pressure (IOP) by reducing the eye’s production of aqueous humor — the fluid inside the eye.

While glaucoma is often associated with impaired fluid drainage, decreasing fluid production helps rebalance the system and effectively control eye pressure.

How ECP Works

ECP is most commonly performed at the same time as cataract surgery (phacoemulsification), though it may also be performed independently in select cases.

During the procedure:

  • A specialized endoscopic probe — equipped with a miniature camera, light source, and fiber-optic laser — is inserted through the same small corneal incision used for cataract surgery.
  • The surgeon directly visualizes the ciliary processes (the structures that produce aqueous humor) on a monitor.
  • A precise 810-nm diode laser is applied to gently shrink and treat these tissues.
  • Typically, 270–300 degrees of the ciliary body are treated.

This direct visualization allows for exceptional precision and controlled treatment.

Why ECP Is Different

Unlike older cyclodestructive procedures, ECP:

  • Minimizes damage to surrounding eye structures
  • Does not require opening the conjunctiva
  • Does not involve external access to Schlemm’s canal
  • Preserves the eye’s natural anatomy

Because the ocular surface remains intact, any future glaucoma procedures—if ever needed—are simpler and carry lower risk.

What to Expect

ECP is performed as an outpatient procedure in an ambulatory surgery center.

  • Local anesthesia with IV sedation (similar to cataract surgery)
  • Typically completed the same day
  • Follow-up visit the next day
  • Postoperative eye drops for 4–8 weeks to reduce inflammation and support healing

Results & Benefits

If successful, ECP can provide:

  • Meaningful reduction in intraocular pressure (IOP)
  • Decreased reliance on glaucoma medications
  • In some cases, discontinuation of certain eye drops
  • Strong safety profile among MIGS procedures
  • Low risk of serious complications

ECP is suitable for various forms of glaucoma, including primary open-angle glaucoma, and is especially effective for patients undergoing cataract surgery with mild to moderate disease.
