1st Liquids for Cataract Surgery

Dispersive viscoelastics, based on hydroxypropylmethylcellulose and cohesive viscoelastics, based on sodium hyaluronate - in various concentrations.

Intraoperative irrigation Solutions - for a safe and complication-free eye surgery.

Dispersive Viscoelastics

Dispersive viscoelastics exhibit short molecular chains and a low molecular weight. They do not lose their viscosity under energy supply and offer excellent protection of the intraocular tissue during the entire cataract procedure. Moreover, they are well suited for moistening instruments.
Different dispersive viscoelastics are available with the following concentrations of hydroxypropylmethylcellulose (HPMC):

1st HPMC Liquid HV 1.8%
Sterile disposable syringe with 1.5 ml solution and disposable injection cannula, Luer-Lock

PeHa Visco HPMC 2.0% & 2.4%
Sterile disposable syringe with 2.0 ml solution and disposable injection cannula, Luer-Lock

Cohesive Viscoelastics

Cohesive viscoelastics exhibit long molecular chains and a high molecular weight. They have pseudoplastic characteristics and can easily be removed after surgery. Another typical benefit of cohesive viscoelastics lies in the intraoperative space-maintaining properties, providing excellent conditions to perform an optimised capsulorhexis.
Various cohesive viscoelastics are available of different origins and with different concentrations of sodiumhyaluronate:

Biological origins (cockscombs):

Microvisc Hyaluron 1%
Sterile disposable syringe with 0.85 ml solution and disposable injection cannula, Luer-Lock
