Relaxing incisions beneficial for presbyopia correction
NEW YORK — In refractive lens exchange, near emmetropia is essential for success, said one surgeon speaking here. To achieve emmetropia, limbal relaxing incisions can be an important component of surgery, the surgeon said.
Modifying the standard cataract incision with limbal relaxing incisions (LRIs) is a simple technique to learn, Steven J. Dell, MD, told attendees at the Ocular Surgery News Symposium: Cataract, Glaucoma & Refractive Surgery.
“LRIs are quick, safe, inexpensive and stable,” he said.
In general, LRIs provide patients with “less discomfort, glare and irregular astigmatism than corneal relaxing incisions do,” Dr. Dell said.
In his practice, Dr. Dell uses LRIs for anything over 0.5 D of corneal cylinder. “It’s always in the steep meridian,” he said. When performing LRIs, undercorrections are preferred, and 4 D is “about the limit for LRI,” he added.
