Ophthalmic surgical device for cataract surgery
Used as surgical aids in ophthalmic anterior and posterior segment surgeries including intra/extra cataract extraction with or without implantation of an intraocular lens (IOL), intraocular lens implantation, keratoplasty / corneal transplantation surgery, glaucoma filtering surgery, and surgical procedurs to reattach the retina. PreviscAid has also been used successfully as a vitreum replacement after vitrectomy and retinal detachment surgery. Due to its lubricating, transparent and viscoelastic properties, PreviscAid aids in maintaining a deep chamber and visibility during anterior segment surgery. While allowing for more efficient manipulation and implantation with less trauma to the corneal endhotelium and other surrounding ocular tissues, PreviscAid may also be used to coat an intraocular lens as wll as the tips of surrounding tissues are protected from possible damage arising from surgical instrumentation during ophthalmic surgeries. PreviscAid also helps preserve tissue integrity and good visibility when used to fill the anterior or prosterior segments of the eye following open sky procedures.

For Cataract Surgery and Intraocular Lens Implantation
PreviscAid is carefully injected into the anterior chamber to replace the aqueous humor before any instrument is introduced into the eye. It can protect corneal endhotelium from surgical instrument damage. PreviscAid can be used before or after removal of the lens. It can also be coated in IOL and surgical instrument. Injection of PreviscAid during surgery can maintain the shape of anterior chamber. Additional PreviscAid can be injected as required during surgery to replace any loss to facilitate surgical manipulation. After surgery PreviscAid can be removed by normal saline.
