Abstract: Non-aspirating viscoelastics, compositions, and methods of use are disclosed. The non-aspirating, transitional viscoelastics possess sufficient viscosity to be useful in ophthalmic viscosurgery, but may be left in the eye with little or no resulting IOP spike. The compositions are particularly useful in cataract surgery.

Abstract: A method for determining the propensity of an intraocular lens material to prevent posterior capsule opacification is disclosed. The method involves contacting a sample of an IOL material having the shape of an IOL optic with collagen to form a contact area, incubating the sample in a liquid composition comprising lens epithelial cells, determining whether lens epithelial cells grow on the collagen in the contact area.

Abstract: The use of HETE derivatives in intraocular surgery (e.g., cataract surgery) is disclosed. The HETE derivatives protect and maintain the corneal endothelium.

Abstract: A method for determining the propensity of an intraocular lens material to prevent posterior capsule opacification is disclosed. The method involves incubating replicate samples of an IOL material with collagen IV, washing off any loosely bound collagen IV. Following the washing step, one sample is counted to determine the amount of collagen IV that remains adhered to the IOL material. A second sample is further processed prior to counting by subjecting it to a desorption step and a further washing step.

Abstract: The use of HETE derivatives in intraocular surgery (e.g., cataract surgery) is disclosed. The HETE derivatives protect and maintain the corneal endothelium.

Abstract: A method of selecting an intraocular lens material for toric lenses is disclosed. The method comprises determining the material's Collagen IV Index.

Abstract: A method is provided for applying a coating to an ophthalmic device by applying a coating to a face of the mold used to make the device and partially curing the coating, or, if the viscosity is sufficiently high, leaving the coating uncured. Then the liquid used to form the lens is poured into the mold and the liquid and coating are concurrently cured.

Abstract: Apparatus for removing biological material from a body thereof comprising a hollow tubular elongate member, one end of which can engage biological material to be removed, a casing in which a portion of the tubular member is mounted for longitudinal sliding movement, a motor which is connected to the casting and has a rotatable drive shaft, means for coupling the rotation of the drive shaft to the tubular member so as longitudinally to vibrate the tubular member and means for withdrawing removed biological material up the tubular member from the said end thereof.
