Two-mm chord manual small-incision cataract surgery with phacofracture

Résumé fourni par la source

We describe a surgical technique for manual small-incision cataract extraction with 2-mm chord incision with phacofracture. The authors describe a curvilinear 2-mm chord incision 1.5 mm behind the limbus and antiparallel to the limbus with back cuts of variable length; 1.5 mm for foldable lenses and 2.5-3 mm for the rigid nonfoldable lenses. Continuous curvilinear capsulorhexis with a 26-G bent needle cystitome (or Utrata forceps) is followed by cortical cleaving hydrodissection and cartwheeling of the nucleus into the anterior chamber. A specially designed Sahu modified vectis (SMV) and a flattened visco cannula are used for the phacofracture. The heminuclei are removed along their longitudinal axis and direct implantation of the pseudophakos. Surgically induced astigmatism was found to be a mean change in astigmatism of 0.14 DCyl when the axis was ignored. Corneal endothelial counts were not vastly different from the routine manual small-incision and phacoemulsification at 3 months of follow-up. The technique used here by the surgeon for cataracts of any C (1-5) or any P (1-5) to grade NC4 NO4 as graded by the LOCS III. Case selection is of paramount importance. Two-millimeter chord MSICS with phacofracture can deliver low astigmatism and good visual recovery in cataract surgery.
