Topical Anesthesia vs. Peribulbar or Retrobulbar Blocks in Cataract Surgery

July 27, 2012

I still do peribulbar (actually, the anesthesiologist does it for me), so when i enter the O.R., the eye sees and feels nothing and doesn’t move. I don’t have to nag the patient to look anywhere, like my residents do. Of course, with coumadin cases, I’ll do topical or sub-Tenon’s. Anyway, a meta-analysis by Dr. Zhu in Ophthalmology showed that topical is more painful than retrobulbar (about equal to peribulbar) – BUT, they excluded those topical cases using intracameral lidocaine, so in my opinion, the study is fatally flawed for practical purposes.

  • I had my cataracts done 3 years ago and what a great thing to have done. I also kept on using gslases as the bifocals help when doing close work and I was so used to wearing them for 50+ years, no one would of recognized me. Enjoy the bright colors but we warned, your eyes will be more sensitive to sunlight for quite awhile. Dark shades are wonderful.

    yeah- diplopia is a very small risk. ive seen it a couple of times. it can be reduced even further by not using marcaine, but only lidocaine- seems the marcaine is toxic if injected into the extraocular muscle, but not lidocaine.

  • I perform topical cataract surgery with intracameral lidocaine. I agree with you that it would be interesting to see the data comparing topical with lidocaine to injection anesthesia.

    It’s completely anecdotal but my uncle had a couple of months of diplopia after cataract surgery with a block. He recovered completely but had difficulty when the diplopia was present. I know it’s a risk but don’t know the incidence.

    Ultimately, we all want our patients to be as comfortable as possible during surgery.
