A water soluble, biodegradable ABA- or BAB-type tri-block polymer is disclosed that is made up of a major amount of a hydrophobic A polymer block made of a biodegradable polyester and a minor amount of a hydrophilic polyethylene glycol(PEG) B polymer block, having an overall average molecular weight of between about 2000 and 4990, and that possesses reverse thermal gelation properties. Effective concentrations of the tri-block polymer and a drug may be uniformly contained in an aqueous phase to form a drug delivery composition. At temperatures below the gelation temperature of the tri-block polymer the composition is a liquid and at temperatures at or above the gelation temperature the composition is a gel or semi-solid. The composition may be administered to a warm-blooded animal as a liquid by parenteral, ocular, topical, inhalation, transdermal, vaginal, transurethral, rectal, nasal, oral, pulmonary or aural delivery means and is a gel at body temperature. The composition may also be administered as a gel. The drug is released at a controlled rate from the gel which biodegrades into non-toxic products. The release rate of the drug may be adjusted by changing various parameters such as hydrophobic / hydrophilic component content, polymer concentration, molecular weight and polydispersity of the tri-block polymer. Because the tri-block polymer is amphiphilic, it functions to increase the solubility and / or stability of drugs in the composition.

A water soluble biodegradable ABA- or BAB-type triblock polymer is disclosed that is made up of a major amount of a hydrophobic polymer made of a poly(lactide-co-glycolide) copolymer or poly(lactide) polymer as the A-blocks and a minor amount of a hydrophilic polyethylene glycol polymer B-block, having an overall weight average molecular weight of between about 2000 and 4990, and that possesses reverse thermal gelation properties. Effective concentrations of the triblock polymer and a drug may be uniformly contained in an aqueous phase to form a drug delivery composition. At temperatures below the gelation temperature of the triblock polymer the composition is a liquid and at temperatures at or above the gelation temperature the composition is a gel or semi-solid. The composition may be administered to a warm-blooded animal as a liquid by parenteral, ocular, topical, inhalation, transdermal, vaginal, transurethral, rectal, nasal, oral, pulmonary or aural delivery means and is a gel at body temperature. The composition may also be administered as a gel. The drug is released at a controlled rate from the gel which biodegrades into non-toxic products. The release rate of the drug may be adjusted by changing various parameters such as hydrophobic / hydrophilic componenet content, polymer concentration, molecular weight and polydispersity of the triblock polymer. Because the triblock polymer is amphiphilic, it functions to increase the solubility and / or stability of drugs in the composition.

A new lens design and method of implantation uses the change in pupil diameter of the eye concurrent with the changes induced by a contraction of the ciliary muscle during the accommodative reflex, in order to assist in focusing of nearby objects. This new intraocular lens consists of two parts. The posterior part or haptic part is inserted behind the iris and in front of the natural lens or artificial implant. Its main purpose is to participate in the accommodative mechanism and to prevent excessive lateral movement and luxation of the lens. An anterior or optical part is made of flexible material and is placed before the iris. Its diameter is variable but should be large enough to cover the pupillary margins to some degree under various conditions of natural dilation. The anterior and posterior part of the lens are separated by a compressible circular groove in which the iris will settle. The diameter of this groove is slightly larger than the pupillary diameter measured under normal photopic daylight conditions and for distance vision. Since the pupil becomes smaller in near vision, the iris will exert a slight pressure at the level of the groove of the lens which will cause a progressive and evenly distributed flexing of the anterior part of the intraocular lens, as the diameter of the compressible circular groove slightly decreases. This flexing will induce an increase in refractive power which corresponds to a variable part of the amount necessary for focusing nearby objects.
