Techniques and instruments for cataract surgery

New techniques for cataract surgery have evolved around access to the cataract, a renewed interest in nuclear expression extracapsular techniques, and a near-completion of the developmental cycle of phacoemulsification back to the original "divide and conquer" strategies. Options to improve access to the cataract include surgical pupil revision, self-retaining iris retractors, and surgical techniques for operating through a small pupil. Nucleus expression through a capsulorhexis is facilitated by global hydrodissection and hydrostatic tilting of the nucleus before removal. New phacoemulsification strategies revolve around the Phaco-Chop method that emphasizes nuclear rim fracturing.
