A supplemental lens assembly for attachment to the position fixation means of a primary intraocular lens to change its optical characteristics. The assembly comprises a supplemental lens body with at least one connecting member extending from it and adapted for attachment to the position fixation means of the primary lens.

The present invention is directed towards a surgical system and method of use for treating and removing unwanted tissue, preferably from an organ or other internal part of a patient. The system includes a cryosurgical component for first freezing the unwanted living tissue by forming an ice mass which completely encompasses the unwanted living tissue and means for treating the cryogenically-treated tissue and then removing the tissue while it remains in a frozen state. In one embodiment, an ultrasonic device is used to ultrasonically vibrate the cryogenically-treated tissue to break apart the frozen tissue and the frozen broken-up pieces of tissue are removed using a technique, such as an aspiration process.

Decentered intraocular lens, usable to correct high myopia of an intact natural lens in an eye having a decentered pupil, by insertion through an eye incision and implanting in the anterior chamber at minimum risk of contacting the natural lens. The intraocular lens includes a lens body having a thickened outer edge and a concave face, and a pair of opposed haptics each terminating in a transverse edge having a pair of laterally spaced lobes to engage adjacent eye tissue at a corresponding pair of spaced tissue points, the transverse edges being of unequal length and arranged at respective distances from the lens body so that the lobes lie in a circle whose center is eccentric to the lens body optical axis, to position the lens body in spaced relating to the natural lens, decentered relative to the circle and eye optical axis and centered relative to the decentered pupil, with the lens body outer edge masked by the iris to inhibit transmission thereat of entering edge glare causing light rays.

An improved tip for use with a device for disintegrating tissue located in a predominantly liquid environment. The tip is connected to an oscillation generator, which results in ultrasonic oscillating movement along the tip axis. When placed within the posterior capsule of an eye, the tip causes the tissue of the natural lens in close proximity to disintegrate. The tip has an elongated curved portion having a convex front surface, a concave rear surface and a rear-facing end surface. The elongated curve of the tip and the rear facing end surface allow easy access to all areas of the capsular bag, some of which were relatively unreachable with known ultrasonic tips.

An injector head forming a hollow cone of spreadable leaves is partially inserted into a minimum size eye incision to inject a temporarily folded intraocular lens into the eye without stressing the incision. An injector device having a holder with a bore holding the lens in folded state is connected to the cone, and a plunger of the device inserted in the bore pushes the lens into and through the cone for controlled gradual injection into the eye and simultaneous controlled gradual unfolding therein.

The present invention relates to a method of treating a patient with visco-surgery, particularly ocular visco-surgery, utilizing a collagen-based viscoelastic solution having a reversibly high viscosity. The invention also relates to collagen-based viscoelastic solutions which further include mucopolysaccarides or growth factors.

An injector formed of a slotted tube is partially inserted via its front end in a minimum size eye incision to inject a temporarily folded intraocular lens having opposed haptics extending from its periphery, into the eye without stressing the incision. Holding and locking mechanisms serve to fold the lens into the tube rear end with the haptics protruding from the tube slot so as not to be jammed in the tube, and to unfold the lens out of the tube front end in the eye for release, all in controlled manner, and so as to avoid patient trauma from stress on the incision or contact of the unfolding lens with the inner wall of the cornea or other eye parts.

The present invention provides a non-biodegradable corneal implant comprising (1) a polymerized transparent collagenous core having acylated amine or esterified carboxyl groups, and (2) a polymerized periphery surrounding the core, the periphery comprising fibrous collagen, e. g. , Type I, being in the form of fibrils under suitable physiological conditions, or fibrillar collagenous material prepared from intact tissue. A method of preparing such an implant is also provided.

A housing for an intraocular lens having opposed walls and having a lens in at least one of these walls which is the same in magnitude and opposite in sign to the optical power of the lens intended to be housed therein. The housing bears indicia of the optical magnitude and sign of the lens intended to be housed therein. A surgeon can ascertain whether the intended lens is in the housing by viewing an object through the housing walls and through the lens housed therein. There will be substantially no optical distortion if the intended lens is in the housing.

The present invention provides a biologically compatible collagenous reaction product comprising ethylenically unsaturated or polymeric substituted collagen, the monomeric substituents being essentially free of nitrogen, e. g. , methacrylate, styrene, polyvinyl, ethylene. The collagenous reaction product can be polymerized, e. g. , by exposure to UV irradiation, chemical agents or atmospheric oxygen, and molded to form useful medical implant articles. Methods of preparation are also provided.
