Why is Viscoat used in cataract surgery?
The main reason for using OVDs in cataract surgery is to prevent damage of the corneal endothelium. Dispersive OVDs, such as Viscoat, are considered to protect the endothelium better than cohesive OVDs, because of their lower specific surface properties [2].
Why are OVDs used during cataract surgery?
OVDs are routinely used in cataract surgery to protect delicate ocular structures, compartmentalize within the eye, pressurize the anterior chamber, and provide a faster and safer surgery with better visual recovery for our patients.
What viscoelastic agents are used in cataract surgery?
Sodium hyaluronate, and other viscoelastic substances including methylcellulose, chondroitin sulfate, polyacrylamide, and collagen, have been used in intraocular surgery since the 1970s (Liesegang 1990).
What is Healon used for in cataract surgery?
INDICATIONS. The HEALONĀ® PRO OVD is indicated for use as a surgical aid in cataract extraction (intra- and extracapsular), IOL implantation, corneal transplant, glaucoma filtration and retinal attachment surgery.
How long does Healon stay in the eye?
Furthermore, the 1% solution of the Healon OVD is transparent, is reported to remain in the anterior chamber for less than 6 days3 and protects corneal endothelial cells4.
What is Ocucoat?
OCUCOAT (hydroxypropylmethylcellulose) is a sterile, isotonic, nonpyrogenic viscoelastic solution of highly purified, noninflammatory, 2% hydroxypropylmethylcellulose with a high molecular weight greater than 80,000 daltons. OCUCOAT (hydroxypropylmethylcellulose) is supplied in 1 mL syringes.
What is DuoVisc?
DuoVisc is a packet containing 2 ophthalmic viscosurgical devices (OVDs): the dispersive Viscoat, which was used for intraocular lens (IOL) implantation. In the Viscoat group, the Viscoat was used during the entire surgery.
What is Provisc used for?
Provisc (1% sodium hyaluronate) is an ophthalmic surgical aid used in the anterior segment during cataract extraction and intraocular lens (IOL) implantation.
What is ocucoat viscoelastic used for?
OcuCoat Viscoelastic Formulated from a 2% hydroxypropyl methylcellulose solution, OcuCoat Viscoelastic is excellent for high-volume, small-incision cataract surgery. It can be used for a variety of applications as an ophthalmic surgical aid in anterior segment surgical procedures, including cataract extraction and intraocular lens implantation.
What are the best viscoelastic characteristics for cataract surgery?
Ideal viscoelastic characteristics during each step of cataract surgery: Maintain anterior chamber depth and keep the anterior lens capsule flat during capsulorrhexis creation. cohesive is best, but dispersive works well also as long as surgeon pivots within the incision (I use dispersive)
Which viscoelastic agents are used in intraocular surgery?
Sodium hyaluronate, and other viscoelastic substances including methylcellulose, chondroitin sulfate, polyacrylamide, and collagen, have been used in intraocular surgery since the 1970s ( Liesegang 1990 ).
What is the difference between Healon D and ocucoat?
This is why Healon D and Viscoat perform nearly identically in the eye, while OcuCoat is somewhat different in performance. With a higher viscosity, cohesive OVDs are able to pressurize the eye and create space, such as during IOL insertion.
