ABSTRACT
Achieving a complete uniform capsulorhexis in an intumescent cataract is perhaps the most crucial and challenging step for surgeons. Star CanVac CCC is a new manual technique for creating a continuous curvilinear capsulorhexis (CCC) in intumescent total cataracts. Small centripetal tears in the shape of a star are created in the center of the anterior lens capsule by using a 26?G cystotome. This allows equal distribution of forces secondary to increased intralenticular pressure, thereby avoiding unidirectional or bidirectional tear extension. Subsequently, a 25?G flat?tipped fine cannula connected to a syringe is used to hold the free capsular flap. The piston of the syringe is withdrawn to create a stable suction pressure, and the rhexis is completed without withdrawing the instrument from the anterior chamber. Our technique is safe, affordable, and an alternative method to routine CCC or expensive techniques such as Femto or Zepto capsulotomy for white intumescent cataracts.
ABSTRACT
We have experienced six cases of postoperative capsular bag distension following continuous curvilinear capsulorhexis(CCC) and phacoemulisification with posterior chamber intraocular lens. Successful CCC, phacoemulsification and in the bag fixation of intraocular lens(IOL) were accomplished, and the optics of the IOL were made of silicone material in 6 cases. We have observed various degree of anterior chamber shallowing, anterior displacement of IOL, bulging of posterior capsule, and myopic shift of refractive error, and these findings improved by YAG laser anterior or posterior capsulotomy. Mean refractive change was +2.6D(diopter) at post-laser 1 day.
