Purpose: To study the outcome of conventional trabeculectomy with or without cataract surgery in different types of glaucoma in low risk cases. Materials and Methods: 50 consecutive eyes, each undergoing conventional trabeculectomy and, 50 eyes combined with cataract surgery are included in this prospective study; each patient had a minimum period of follow-up for six months. Preoperative details of medications, visual acuity, slit lamp evaluation, applanation tonometry, cup to disc ratio and visual fields were compared with similar parameters postoperatively. __ampersandsignldquo;Complete success__ampersandsignrdquo; was defined in this study as intraocular pressure (IOP) __ampersandsignlt;21mmHg or 30% reduction from the preoperative IOP. Latest IOP recorded in each eye has been considered for this study. Results: Postoperative mean IOP in the trab group was 13.08 + 3.52 mm Hg and in combined group it was 13.70 + 3.31 mm Hg during 100% visits, with follow ups ranging from six months to __ampersandsigngt; 5 years. There was no significant difference in IOP reduction between trabeculectomy and combined groups. 87% of long-term __ampersandsignldquo;Complete Success__ampersandsignrdquo; rate in both the groups and 76% visual outcome of __ampersandsigngt; 6/18 in the combined group may be attributed to minimum rate of complications. Conclusion: Conventional trabeculectomy without using antimetabolites is successful even in the present day glaucoma management in low risk glaucoma cases, when performed with technical precision aided by vigilant postoperative care. It is equally effective and convenient when combined with cataract surgery in relevant cases.
