MODIFIED PHACOEMULSIFICATION IN-SITU

We describe a phacoemulsification technique for cataracts in eyes with anticipated weak zonular apparatus. After central sculpting, a crater 90% deep is made. A horizontal fracture is created with the phaco pro be and chopper. The nucleus is chopped, dividing the inferior hemisect ion into 2 pie-shaped pieces, which are then emulsified. Without rotat ing the nucleus, a groove is made at the Superior hemisection and a ve rtical fracture created with the chopper. The bevel of the phaco probe is then turned down to emulsify each quadrant separately. This techni que is especially useful in eyes with weakened zonular apparatus such as those with hypermature cataract, uveitis, long-standing glaucoma, t rauma, retinitis pigmentosa, and operated retinal detachments.
