[0024] The present invention also provides the preparation method of this non-steroidal anti-inflammatory eye drop, it is characterized in that comprising the steps:
[0025] A, disperse the flurbiprofen prodrug with an appropriate amount of water for injection, and set aside to obtain liquid A;
[0026] B. Disperse the thickener with an appropriate amount of water for injection and let it cool, then add the antibacterial agent, stir well and filter, add to the liquid A obtained in step A) to obtain liquid B;
[0027] C. Dissolve the pH adjuster with water for injection, slowly add it to liquid B, adjust the pH value to 5.5-7.5, and obtain liquid C;
[0028] D. Dissolve the osmotic pressure regulator with water for injection, slowly add to the solution C obtained in step 3), adjust the osmotic pressure molar concentration to 250-350mOsmol / kg, and obtain liquid D;
[0029] E. Add water for injection to the liquid D to make up the volume, so that the concentration of flurbiprof...
