Embodiment 1
[0033] Example 1: In this example, a foldable intraocular lens containing gatifloxacin was prepared.
[0034] The preparation method comprises the following steps:
[0035] (1) Prepare a polyurethane acrylate prepolymer: the molar ratio of isocyanate: polyether polyol: hydroxy acrylate is 2:1:2.1. The reaction vessel is a 250ml four-necked flask, which is connected with an overhead mechanical stirrer, a reflux condenser, a constant pressure dropping funnel, a thermometer, and nitrogen gas. The heating device is an oil bath. 4.4456 g of isophorone diisocyanate and 0.0086 g of a catalyst dibutyltin dilaurate were put into a four-necked flask, and 10.0000 g of polyethylene glycol-1000 was added dropwise at 60°C. After reacting for 2 hours, slowly add 2.4385g of 2-hydroxypropyl acrylate and 0.0273g of hydroquinone, raise the temperature to 80°C and continue the reaction for 3 hours to obtain a transparent viscous liquid, which should be sealed and stored in a cool place.

Embodiment 2
[0041] Example 2: In this example, a foldable intraocular lens containing levofloxacin was prepared.
[0042] The preparation method comprises the following steps:
[0043] (1) Prepare a polyurethane acrylate prepolymer: the molar ratio of toluene diisocyanate: polytetrahydrofuran-1000: 2-hydroxyethyl acrylate is 5:1:8.1. The reaction vessel is a 250ml four-necked flask, which is connected with an overhead mechanical stirrer, a reflux condenser, a constant pressure dropping funnel, a thermometer, and nitrogen gas. The heating device is an oil bath. Put 9.4057g of 2-hydroxyethyl acrylate and 0.0930g of hydroquinone into a four-neck flask, add 8.7100g of toluene diisocyanate dropwise at 30°C, and react for 5 hours, then slowly add 10.0000g of polytetrahydrofuran-1000, and raise the temperature The reaction was continued at 40°C for 6 hours to obtain a transparent viscous liquid, which was sealed and stored in a cool place.
