Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims at detecting the minimum effective daily dose and duration of difluprednate that can be used to treat postoperative inflammation after phacoemulsification without increasing the intraocular pressure, and whether it can be safely given within the first 24 hours after the operation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Conventional phacoemulsification will be performed by the same surgeon for all the cases using the stop and chop technique. Anterior chamber examination for flare and cells using slit-lamp biomicroscopy according to the SUN recommendations and intraocular pressure measurement using Goldmann applanation tonometer will be done for all the cases before surgery and on the 1st, 3rd, 7th, 14th days as well as one month after the procedure.

All cases will receive Nepafenac 0.1% ( Nevanac 0.1%) 3 times per day on the last preoperative day, one tablet of Acetazolamide 250 mg (Cidamex 250mg) within the first 3 hours after the procedure and Moxifloxacin (Vigamox 0.5%) 0.1 ml intracameral and post-operative drops 3 times per day for 10 days and will be divided into:

In this pilot study:

* Group A : will receive Difluprednate 4 times per day for 1 week, then twice per day for 1 week and then once per day for 5 days starting 24 hours after the operation
* Group B : will receive Difluprednate 3 times per day for 4 days, then twice per day for 4 days and then once per day for 4 days starting 4 hours after the operation
