- n. Removal of a cataract by emulsifying the lens ultrasonically.
from Wiktionary, Creative Commons Attribution/Share-Alike License
- n. A form of cataract surgery in which the eye's internal lens is emulsified with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution, thus maintaining the anterior chamber, as well as cooling the handpiece.

- n. extracapsular surgery for cataracts in which ultrasonic sound breaks the cortex and nucleus of the lens into small fragments that are then vacuumed away through a small tube
The nucleus is being removed by being expressed in one piece manually or by phacoemulsification or the process of breaking it using localized high-pitched sound waves.
Given the well-known advantages of sutureless, vitrectomy and paucity of post-operative hypotony and endophthalmitis, we feel that the 23-gauge instrumentarium is the method of choice when combined with phacoemulsification for non-posturing, macular hole surgery.
Combined 23-gauge, sutureless transconjunctival vitrectomy with phacoemulsification without face down posturing for the repair of idiopathic macular holes
The most common method of cataract surgery is phacoemulsification.
Posterior capsular rupture during phacoemulsification is the most common cause of posterior displacement of lens fragments.
Our future success in emerging markets is predicated on establishing the phacoemulsification procedure to remove the cataract and use of a foldable IOL as the standard of care in these markets.
Most cataract surgeries are performed using a procedure known as phacoemulsification.
