If capsular rim was wider than expected normal due to improper rhexis 1 to 2 radial cuts were given occasionally.
They cover phaco surgery, microincisional cataract surgery, challenging cases, and complications, and include incision, capsulorrhexis, hydrodissection, nuclear dissection, horizontal and vertical chopping, phacoemulsification, biaxial microincisional surgery, posterior polar cataract, iris hooks in small pupil phaco, subluxated cataracts, torn rhexis, irrigation and aspiration, and intraocular lens insertion procedures.
