Best Practices for In-Office SLT

Nicholas R. Green, OD, MPH, FAAO, stressed the importance of careful patient selection in his “Tips, Tricks, and New Technologies for In-Office Laser Procedures” presentation at Optometry’s Meeting 2026 in Phoenix, which covered SLT, LPI, and YAG. In this installment, we're covering SLT.

Optometric Management

Overview

Selective laser trabeculoplasty (SLT) is utilized by optometrists to provide glaucoma treatment. Proper patient selection and adherence to best practices are essential.

Background

As laser privileges expand for optometrists in the U.S., in-office procedures like SLT provide access to care for patients in underserved areas. Understanding SLT is vital for effective glaucoma management.

Data Highlights

Procedure	CPT Code	CMS Nonfacility Reimbursement Rate
Selective Laser Trabeculoplasty (SLT)	65855	$240.09
Laser Peripheral Iridotomy (LPI)	66761	$292.20
YAG Capsulotomy	66821	$327.45

Key Findings

SLT lowers intraocular pressure (IOP) by approximately 20% to 30% in open-angle glaucoma patients.
Careful patient selection is crucial; contraindications include narrow angles and significant intraocular inflammation.
Monitoring postoperative IOP is recommended 30 to 60 minutes after treatment.
Research supports treating 360° of the trabecular meshwork for optimal IOP reduction.
