Intraocular lens scaffold technique to prevent posterior capsule rupture in cases of Morgagnian cataract.
We describe a technique for performing safe phacoemulsification of a Morgagnian cataract using the intraocular lens (IOL) scaffold. An IOL scaffold has been used in cases in which posterior capsule rupture has occurred, leaving nonemulsified nuclear pieces. The scaffold provides a barrier that prevents the nuclear fragments from falling posteriorly into the vitreous cavity. Our technique uses the IOL as a scaffold to prevent the vulnerable posterior capsule from rupturing during nuclear emulsification in Morgagnian cataract. The technique prevents rupture of the floppy posterior capsule by providing a constant support to it. The scaffold provides stable inflation of the capsular bag and prevents inadvertent emulsification. Concurrently, it prevents dehiscence of weak zonular fibers by minimizing the stress on the zonular apparatus.
