Abstract: A contact lens is disposed in a well containing hydration fluid, such that a concave surface of the lens faces upwardly and the lens is submerged in the hydration fluid, thereby allowing contaminants to leach out of the lens into the hydration fluid. After hydration, a washing fluid is introduced into the well and contaminated hydration fluid is removed from the well so as to replace at least some of the contaminated hydration fluid in the well with the washing fluid in a predetermined fluid-exchange procedure. The washing fluid is introduced into the well so as to be directed against the concave surface of the lens and the contaminated hydration fluid is removed at a removal location remote from where the washing fluid impinges against the lens, such that the action of the introduced washing fluid serves to oppose The predetermined fluid-exchange procedure is monitored so as to establish whether the predetermined fluid-exchange procedure has been correctly performed.

Abstract: An iris-supported intraocular lens having an optic portion and a plurality of fixation members coupled thereto. Each fixation member has a pair of pincer arms that separate outward of the optic and converge toward one another at aligned end tips. One or both of the end tips are covered with a soft sleeve or cap. The IOL is fixed in the anterior chamber of the eye by pinching the iris tissue between the end tips of each pair of pincer arms. The soft sleeves eliminate damage to the iris tissue.

Abstract: An improved opthalmic lens is disclosed which has a plurality of alternating power zones with a continuously varying power within each zone, as well as in transition from one zone to another. In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa. This change is continuous (progressive), without any abrupt correction changes, or “edges”. Two versions of the invention are disclosed. In the first version continuous, alternating power variation is accomplished by a continuously changing curvature of the lens posterior surface, thereby altering the angle of impact of light rays on the eye.

Abstract: A cast mould for use in the manufacture of a contact lens by the polymerisation of a flowable precursor comprises a female mould part and a male mould part. The female mould part has a concave first surface region adapted to receive the flowable precursor in use, and a second surface region. The male mould part has a convex first surface region and a second surface region. The male mould part is engageable with the female mould part to define a lens-forming recess between the concave and convex surface regions and to define a first overflow cavity between said second surface regions. The first overflow cavity is adapted to receive excess flowable precursor displaced from the lens-forming recess in use, and the first overflow cavity is provided with first retaining means such that, in use, after polymerisation, polymer in the first overflow cavity is mechanically interlocked with a single one of the mould parts after separation of the mould parts.
