Researchers argue that a study published in April issue of Ophthalmology, which concludes that topical anesthesia is less effective than regional anesthesia for patient pain relief, does not reflect how phacoemulsification is performed in the U.S., according to a Medscape report.
The study, performed by ophthalmologists at the Shanghai Jiao Tong University School in China, evaluated 15 randomized clinical trials comparing the performance of topical and regional anesthesia during phacoemulsification with lens implantation.
But the Shanghai researchers reduced the value of their meta-analysis for US ophthalmologists when they specifically excluded studies of topical anesthesia used in combination with intracameral lidocaine, said James Salz, MD, clinical professor of ophthalmology at the University of Southern California.
