Abstract
Injectable collagen-based compositions can be used in methods to fill a lens capsular sac, following lens extraction procedures, to form a new intraocular lens. Purified soluble or partially fibrillar collagen may be modified with acylating agents, sulfonating agents or combinations thereof to form a clear, transparent collagen composition having indices of refraction between about 1.2 to 1.6. The modified collagen may injected into a lens capsular sac to form an intraocular lens (IOL) in situ. The IOL is clear, transparent, resistant to epithelialization and is capable of accommodation. The collagen-based IOL produced by the method of the present invention may remain in its original viscous liquid state or may be polymerized into a soft gel. The collagen-based IOL may be used to replace diseased or natural lens to treat cataracts, presbyopia, myopia and hyperopia.
