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.

Effects of ultrasound energy on the porcine corneal endothelium – Establishment of a phacoemulsification damage model

Acta ophthalmologica, 2020
The purpose of this study was to establish a standardized in vitro phacoemulsification damage model for future investigations of the effects of phacoemulsification, surgical devices, protective ophthalmic viscoelastic devices (OVDs), irrigation solutions

New phacoemulsification technologies

Journal of Cataract and Refractive Surgery, 2002
To examine recent developments in the field of phacoemulsification, a literature review was conducted for each system described. the review included peer- reviewed articles, information from manufacturers, and meeting presentations by surgeons. our personal experience with systems we have used forms the underlying basis of our evaluation.

Microkeratome-assisted phacoemulsification

Journal of Cataract and Refractive Surgery, 2005
This study reports a technique in which phacoemulsification and intraocular lens (IOL) insertion are performed in conjunction with a microkeratome flap in a patient with ocular surface disease. Microkeratome-assisted phacoemulsification was performed in a 72-year-old woman with a history of trachoma during childhood.

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 ...

V-style phacoemulsification

Journal of Cataract and Refractive Surgery, 1993
A technique designed to reduce zonular stress and ensure safe intercapsular phacoemulsification is described. This one-handed method is especially effective in eyes with strong adhesions between nucleus and cortical layers where hydrodissection is not possible.

Phacoemulsification, visco-goniosynechialysis, and goniotomy in patients with primary angle-closure glaucoma: A comparative study

European Journal of Ophthalmology, 2019
Objective: The aim of this study was to evaluate the effects of goniotomy on patients with primary angle-closure glaucoma who underwent “phacoemulsification and visco-goniosynechialysis.” Materials and methods: This prospective randomized clinical trial ...

Phacoemulsification Versus Phacotrabeculectomy in Primary Angle-closure Glaucoma With Cataract: Long-Term Clinical Outcomes

Journal of glaucoma, 2019
Precis: Phacotrabeculectomy was more effective in reducing intraocular pressure (IOP) and glaucoma drugs than phacoemulsification alone in primary angle-closure glaucoma (PACG) eyes with cataract but was associated with more postoperative complications ...

Mitomycin C-augmented Phacotrabeculectomy Versus Phacoemulsification in Primary Angle-closure Glaucoma: A Randomized Controlled Study.

Journal of glaucoma, 2019
PRECIS Phacotrabeculectomy yielded similar results to phacoemulsification in primary angle-closure glaucoma (PACG) in terms of intraocular pressure (IOP) lowering, glaucoma medications and success rates.

Three-phase phacoemulsification

Journal of Cataract and Refractive Surgery, 1998
In phase 1 of three-phase phacoemulsification, an endocapsular nuclear emulsification technique, two intersecting grooves divide the nucleus into four quadrants. The grooves are short and involve most of the thickness of the nucleus. In phase 2, the standard irrigation/aspiration flow is reversed by a valve. Fluid enters the eye via the ultrasound tip,
