|6. |BRIEF RESUME OF THE INTENDED WORK: |
| |6.1 Need for study: |
| |Cataract is the leading cause of blindness worldwide and cataract extraction is |
| |the treatment of choice leading to improvement in quality of life, cognitive function and |
| |productivity as reported by multiple published studies.1 To maximize the outcome of |
| |cataract surgery, post-operative treatment includes antimicrobials, NSAIDs and a potent |
| |steroid.1 Studies have shown the benefit of antimicrobials in prophylaxis against ocular |
| |infection and endophthalmitis, NSAIDs for reducing macular edema and steroids for |
| |reducing anterior chamber reaction.1 From the perspective of the adverse effects of |
| |steroids like delayed wound healing, increase in intraocular pressure and increase in |
| |chances of infection due to non specific immunosuppressive action, the postoperative |
| |use of steroids is best avoided.2 |
| |The advent of topical NSAIDs provides the ocular surgeon with alternative |
| |approach to the control of postoperative inflammation that may have distinct advantages |
| |over the corticosteroid use. Topical NSAIDs are of multifunctional therapeutics. They |
| |were first used in cataract surgeries for the prevention of surgically induced miosis, but |
| |now they have been shown to be effective in controlling pain of the surgery and to have |
| |the potential in treating and preventing cystoid macular edema. The NSAID, Bromfenac |
| |has shown to reduce the surgically induced miosis, ocular inflammation and CME.3 |
| |The recent advances in the cataract surgeries like phacoemulsification and the |
| |use of foldable IOLs, the chances of postoperative ocular inflammation are reduced.2 |
| |Chances of high grade fibrinous reaction is low.2 So, the use of potent steroids can be |
| |avoided and instead Non Steroidal Anti Inflammatory Drugs can alone be used in |
| |combating the ocular inflammation. So a study is needed for the substitution of potent |
| |steroids with Non Steroidal Anti Inflammatory Drug like Bromfenac sodium. Hence in |
| |the present study, the effects of bromfenac sodium will be studied and compared with |
| |that of prednisolone acetate in postoperative cataract patients. |

| |6.2 REVIEW OF LITERATURE: |
| |1. Duong HQ, Westfield KC, Singleton IC studied taking 137 patients at Las Vegas, |
| |USA, the comparison of Intraocular Pressure, degree of post operative anterior |
| |chamber inflammation and macular edema among three different groups with different |
| |treatments in a prospective, randomized, single blind study. Preoperative evaluation |
| |included a comprehensive ophthalmic examination and baseline macular optical |
| |coherence tomography (OCT). The control group was given gatifloxacin 0.3%, |
| |prednisolone acetate 1% and bromfenac 0.09%. The second group was given |
| |gatifloxacin 0.3% and bromfenac 0.09%.The third group was given one intraoperative |
| |steroid (triamcinolone) injection, gatifloxacin and bromfenac in the postoperative |
| |period. Postoperative data included intraocular pressure and anterior chamber cell |
| |count at 1 day, 1 week and 1 month postoperatively. Macular OCTs were performed at |
| |1 week and 1 month postoperative. This study concluded that all the three regimens |
| |were equally efficient in decreasing the IOP and preventing the cystoid macular edema |
| |(foveal thickness was used to determine the degree of macular inflammation). The study |
| |was statistically insignificant with p=0.39 for anterior chamber inflammation and |
| |p=0.82 for foveal thickness .The IOP were high on 1st postoperative day but were |
| |statistically insignificant (p=0.15). The IOPs reached normal level by one week.1 |
| | |
| |2. Nishino M, Eguchi H, Iwata A, Shiota H, Tanaka M, Tanaka T in Japan, conducted a |
| |single blind, randomized and prospective study in 21 patients, with 11 patients assigned |
| |to steroid group and 10 to non steroid group. After phacoemulsification with posterior |
| |chamber IOL, they were given the respective drugs that were assigned to them. Visual |
| |acuity, anterior chamber flare and cells and corneal endothelial cell density were |
| |examined. After 1 month postoperatively, no difference was observed between the two |
| |groups in terms of the outcomes described earlier. No evidence of CME was detected. |
| |This study concluded that, topical steroid medication may not be absolutely essential |
| |after an uneventful Phacoemulsification with posterior chamber IOL.2 |
| | |
| |3. Donnenfeld ED, Holland EJ, Stewart RH, Gow JA, Grillone LR conducted a |
| |multicenter, randomized, double masked, parallel, placebo controlled clinical trial to |
| |evaluate the efficacy and ocular safety of Bromfenac ophthalmic solution 0.09% for the |
| |treatment of postoperative inflammation and reduction of ocular pain in subjects who |
| |underwent cataract extraction. 527 subjects were assigned sequentially according to a |
| |computer generated randomized list in 2:1 ratio i.e. 2 bromfenac to 1 placebo ratio. The |
| |subjects without any prior anti inflammatory treatment with postoperative Summed |
| |Ocular Inflammation Score(SOIS) of 3 or more than 3 were treated with either |
| |Bromfenac or the placebo instilled twice daily for 14 days. They were observed on 15th |
| |day. The baseline mean SOIS was 3.7 in both groups. A greater proportion of bromfenac |
| |(64%) than placebo subjects (43.3%) achieved complete clearance of ocular |
| |inflammation on 15th day (p ................
