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.

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 ...

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.

Modified phacoemulsification in situ

Journal of Cataract and Refractive Surgery, 1998
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 probe and chopper. The nucleus is chopped, dividing the inferior hemisection into 2 pie-shaped pieces, which are then emulsified.

Hearing loss and phacoemulsification

Journal of Cataract and Refractive Surgery, 2000
To determine the acoustic spectra of currently used phacoemulsification units and to contrast phacoemulsification-generated acoustic spectra with representative audiograms of common types of sensorineural hearing loss.Mayo Clinic, Rochester, Minnesota, USA.The acoustic spectra of 3 phacoemulsification systems (Alcon Series 20,000 Legacy, Storz ...

New phacoemulsification technology

Current Opinion in Ophthalmology, 2005
Familiarization with each of the manufacturers' latest machines and upgrades assists in understanding the advances made in phacoemulsification technology.Improvements in the delivery of energy through power modulations, alternative and adjunctive energy sources, and advanced fluidics allow the safe use of bimanual microincision techniques for lens ...

Advances in phacoemulsification equipment

Current Opinion in Ophthalmology, 2002
The purpose of this article is to update information on the phacoemulsification equipment based on a systematic review of available literature within the past year. Phacoemulsification has gained acceptance as the standard technique for cataract surgery worldwide, and new phacoemulsification techniques and equipment have been reported.
