Patients with and without glaucoma who underwent Nd:YAG capsulotomy had no immediate significant IOP change and no retinal tears or detachments after 1 week, according to a poster presented at Cataract Surgery: Telling It Like It Is.

Jessica Yang, MD, and colleagues examined data from patients who underwent Nd:YAG laser capsulotomy at the University of Florida between 2011 and 2020. Differences in IOP after 30 minutes and at a 1-week follow-up dilated fundus examination were noted. Patients who had a YAG procedure “for reasons other than posterior capsular opacification, IOP not recorded, and glaucoma status not analyzed” were not included in the data review, according to the poster. A total of 578 patients, 93 of whom had glaucoma, were included.

There was no significant immediate or sustained increase in IOP in glaucoma and nonglaucoma patients who receive YAG laser capsulotomy, Yang told Healio/OSN.

“The main take-away points from this retrospective study are that there is no significant immediate or sustained increase in IOP in glaucoma and nonglaucoma patients who receive YAG laser capsulotomy and that the rate of retinal detachment after YAG laser capsulotomy continues to remain low,” Yang told Healio/OSN.

In all patients and in glaucoma patients evaluated, there was no significant difference between IOP before and after the procedure. Having glaucoma did not increase the risk of a rise in IOP of 5 mm Hg or more; 19% of those who experienced increased IOP had glaucoma, “which was comparable to the prevalence of glaucoma (16%, N = 92) in our data set,” the researchers wrote.

Additionally, Yang and colleagues found that 1-week dilated fundus exams revealed no retinal tears or detachments in any patients.

“This is important because it brings into question the necessity of having YAG laser capsulotomy patients wait in-office for 30 minutes after their procedure for an IOP check and for them to return to clinic again in 1 week for a dilated exam looking for retinal pathology,” Yang told Healio/OSN.
