Efficacy Comparison Study of Steroids to Control Post-operative

Status Recruiting

Clinical Trial Summary

Phacoemulsification is a quick method with less complication for cataract surgery. Due to the use of ultrasonic energy, it produced more post-operative inflammation than other methods. Many routes of steroid had been used to control post-operative inflammation. The investigators here compare the efficacy of single depot steroid subtenon injection (20-mg triamcinolone) with four-time-a-day steroid eye drop (0.1% dexamethasone) in controlling inflammation after uneventful phacoemulsification.

Clinical Trial Description

Cataract is one of the most common causes of blindness in the world. Surgical removal of lens is the only treatment for cataract, which now shifts from extracapsular cataract extraction to phacoemulsification. Although phacoemulsification provides faster operating time and gives better optical result and rapid recovery to the patient, it causes more inflammation post-operatively compare with extracapsular cataract extraction. Corticosteroids eye drops are mainly use to control intraocular inflammation after the surgery.

Other routes of corticosteroids have been introduced to increase the intraocular level and to increase the patient's compliance. Subtenon triamcinolone injection is easy and safe. Antiinflammatory effect of single subtenon triamcinolone injection lasts about 4-6 weeks. This method has been used in combination with corticosteroid eye drop to control the inflammation after cataract surgery in uveitic patients. It shows potency in controlling of intraocular inflammation with lower rate of increasing the intraocular pressure. The investigators here quantitatively compare the efficacy of subtenon 20-mg triamcinolone injection with 0.1% dexamethasone eye drop in controlling intraocular inflammation after uneventful phacoemulsification. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
