Conjunctival Flap protected limbo corneal SICS tunnel using 3mm Keratome (2)

SICS is a commonly used technique of doing cataract surgery along with IOL implantation especially in eye camps. In a classical SICS we make a conjunctival flap, do heat or bipolar cautery to control bleeding, make a tunnel incision using a knife, crescent knife and keratome to make the self-sealing valvular incision. Cauterization destroys lymphatics/aqueous channels and may worsen the existing glaucoma or change a borderline glaucoma to a moderate glaucoma. Using the technique shown in the video one can avoid construction of a conventional conjunctival flap but still have the advantage of a conjunctival flap and its advantages i.e. the safety of covering the wound which gives an additional protection to prevent post op infection without compromising the aqueous channels. The keratome is put about 5mm away from limbus and conjunctiva is dragged towards limbus and then the tip of the keratome is used to initiate and complete the incision as routinely done. This way a conjunctival flap is created which covers the incision. The rest of the surgical steps are the same. Of course classical SICS is the best surgery if one is not contemplating phacoemulsification. This variant may be tried if surgeon is comfortable with a little messy surgery due to bleeding. Certainly the post op results are comparable.
