The precision of the capsulotomy allows a more precise effective lens position. The advantages are further pronounced in intumescent and subluxated cataracts, wherein initiation and subsequent completion of the rhexis is a challenge. Nucloetomy patterns allow removal of the nucleus with relative ease, even in dense brunescent cataracts. This allows reduced «œÃ̜«iÀ>̈Ûi ˆ˜y>““>̈œ˜ >˜` clearer corneas postoperatively. The integrated anterior segment imaging allows an additional advantage to assess the integrity of the posterior capsule. Anterior penetrating and intrastromal arcuate keratotomies can be planned more centrally vis-à-vis limbal relaxing incisions, allowing a greater keratometric impact and lower risk of regression.
