Modified limbal relaxing incision less effective for astigmatism
MUNICH, Germany A modified limbal relaxing incision technique results in excellent uncorrected visual acuity after cataract surgery but is less effective at reducing astigmatism than standard limbal relaxing incisions, according to a report here.
Eriko Fukuyama, MD, authored a poster presentation on the modified technique here at the European Society for Cataract and Refractive Surgeons meeting.
Dr. Fukuyama reported on 387 eyes that were divided into three groups: 84 eyes underwent cataract surgery alone, 123 eyes underwent astigmatic keratotomy concurrently with cataract surgery, 116 eyes underwent limbal relaxing incisions (LRIs) during cataract surgery and 64 eyes underwent modified LRIs with simultaneous cataract surgery.
The mean keratometric cylinder decreased compared with preoperative levels in the astigmatic keratotomy group, the LRI group and the modified LRI group.
Compared to corneal relaxing incisions and usual LRI, new LRIs are a weaker corrective procedure, Dr. Fukuyama wrote. In general, he said, LRI procedures cause few complications such as corneal perforation, overcorrection and astigmatism.
