Petalloid Phacoemulsification

Ophthalmic Surgery, Lasers and Imaging Retina, 2000
Abstract. Hard grade IV nuclei are difficult to emulsify without causing additional stress on the zonular apparatus. We herein, describe a method to accomplish successful phacoemulsification in hard cataracts. This technique of "petalloid phacoemulsification" consists of partial central debulking, followed by sequential chopping to create petal-shaped ...

Phacoemulsification

Ophthalmology, 1978
Ten years have passed since the phacoemulsification procedure was introduced to ophthalmology. Enough experience has now been gained to evaluate its effectiveness. This report sets forth a list of case-selection criteria designed to avoid the most common complications associated with the operation.

Complications of Phacoemulsification

Ophthalmology, 1978
Charles Kelman performed the first phacoemulsification operation in 1967, but it was not until 1971 that the technique had been sufficiently refined to allow its use by others. Now over 2,000 surgeons have been trained in the technique, and more than 100,000 cases have been performed.

Phacocryolysis and Phacoemulsification

American Journal of Ophthalmology, 1977
The effect of rapid freezing and thawing was tested in vitro on 100 human hard nuclear cataracts before ultrasonic emulsification. After phacocryolysis the interspace between lens fibers increased, and the normally closely packed fibers appeared to loosen. This seemed to soften the hard cataract, thereby facilitating ultrasonic emulsification.
