We have learned from the past two days of videos, that it is sometimes wise to revert to a can-opener capsulotomy when the capsulorhexis is radialized. This is a case presented by guest surgeon Dr. Eduardo Tomazoni who is an ophthalmology resident at Governador Celso Ramos hospital in Brazil. This case starts begins with a junior resident operating and there is a radialization of the capsulorhexis toward the lens equator, but it gets worse: as the forceps are pulled out of the eye, the subincision capsule is inadvertently grabbed and that, too, radializes. Now with two areas of capsular tear-out, what is the best move?
This is a good situation in which to perform a can-opener capsulotomy. This creates a round opening in the anterior lens capsule and also creates multiple sites where capsular bag stress can be dissipated. If we instead try to do a capsulorhexis and leave just one or two areas of runout, these areas will absorb all of the capsular forces and that will lead to further runout of the tear, all the way to the posterior capsule.
Watch this video carefully because there is a lot to learn from Dr. Tomazoni. He did a great job in rescuing this surgery. The next time you have a capsular runout, ask for the cystotome and perform a can-opener capsulotomy.
