Abstract

Purpose:

To present a case of a patient who suffered a macular burn after an attempted YAG laser capsulotomy because of the inadvertent use of the selective laser trabeculoplasty mode of a dual-mode laser.

Method:

Case report.

Results:

A 62-year-old man with slight opacification of the posterior capsule noted sudden central vision loss immediately after an attempted YAG laser capsulotomy. The selective laser trabeculoplasty mode of a dual-mode laser had inadvertently been used. Color photographs, fluorescein angiography, and spectral domain optical coherence tomography revealed a laser burn in the macula. The patient's central vision was impaired.

Conclusion:

Inadvertent selection of the selective laser trabeculoplasty mode when attempting to perform a YAG laser capsulotomy with a dual-mode laser may cause a macular burn with impairment of central vision. We encourage all users of dual-mode lasers to actively choose and verify the appropriate settings to minimize the risk of inadvertent retinal damage.
