Posterior optic buttonholing prevents intraocular pressure peaks after cataract surgery with primary posterior capsulorhexis

Abstract

Postoperative IOP peaks after cataract surgery with sole PPC can be effectively prevented by the buttonholing of the IOL through the posterior capsulorhexis.

Impact of primary posterior capsulorhexis on regeneratory after‐cataract and YAG laser rates with an acrylic micro‐incision intraocular lens with plate haptics: 1‐year and 3‐year results

“…Other than with open‐loop IOLs (Stifter et al. , ), no early IOP rise or peaking occurred after additional PPCR in the early postoperative period. No case of vision‐reducing CME was seen at 1 month or reported.…”

“…The hermetical sealing of the PPCR by the monobloc IOL should avoid postoperative IOP rises and peaks seen with looped IOLs by trapping the OVD left back behind the IOL (Stifter et al. , ). In the early postoperative period, the OVD cushion trapped behind the closed diaphragm may additionally withhold inflammatory cytokines from reaching the macula and thus have a positive impact on the CME rate.…”

Effect of primary posterior continuous curvilinear capsulorrhexis with posterior optic buttonholing on pilocarpine-induced IOL shift

“…[13][14][15][16][17][18][19] Therefore, removing the posterior capsule should inherently reduce the constricting factor of the capsule and thus enhance the axial mobility of the IOL.…”
