A composition for debridement of retained lens materials, comprising an effective amount of ethylenediaminetetraacetic acid (EDTA) or salts thereof and a viscoelastic material in an amount sufficient to prevent leakage of said EDTA or salts thereof from a lens capsule, both dissolved in a physiologically acceptable solution.
A composition for debridement of retained lens materials comprising a viscoelastic material and ethylenediaminetetraacetic acid or salts thereof both dissolved in a physiologically acceptable solution, the viscosity of the solution containing the viscoelastic material and ethylenediaminetetraacetic acid or salts thereof being 10,000 to 100,000 cP, and the concentration of the ethylenediaminetetraacetic acid or salts thereof being in the range of 5 to 50 millimol/l.
A composition for debridement of retained lens materials comprising sodium hyaluronate having a moleculer weight of 600,000 to 4,000,000, and ethylenediaminetetraacetic acid or salts thereof both dissoloved in a physiologically acceptable solution, the viscosity of the solution containing the viscoelastic material and ethylenediaminetetraacetic acid or salts thereof being 10,000 to 100,000 cP, and the concentration of the ethylenediaminetetraacetic acid or salts thereof being in the range of 5 to 50 millimol/l.
