Introduction: Placement of a posterior chamber scleral fixated intraocular lens (SF-IOL) is the only option for patients whose eyes lack zonular or capsular support. Long-term data comparing the various techniques used to place scleral fixation intraocular lens (SF-IOL) will be crucial to identify optimal strategies for scleral fixation intraocular lens (SF-IOL) implantation. Aim of the study: The aim of the study was to observe the visual outcome after SFIOL implantation following PPV in case of dropped intraocular lens. Methods: This prospective observational study was conducted at National Institute of Ophthalmology & Hospital, Dhaka, Bangladesh. The study duration was 6 months, from August 2019 to January 2020. The study was conducted with a total of 30 patients with aphakia due to dropped intraocular lenses. The patients were selected non-randomly on a first come first serve basis. Results: The mean age of the participants was 57.7±7.64 years and the majority (60.0%) were female with 66.67% had left eye involvement. Mean visual acuity at baseline was 1.34 ± 0.26 (SD) in the Log MAR unit, which had significant improvement at each follow-up period. After 3 months visual improvement was 0.34±0.27 in LogMAR unit. A few cases of corneal edema, raised intraocular pressure, lens decentration and some other complications were observed after surgery. Conclusion: In most cases, a decent optical outcome may be reached by using this surgical approach. To prove that it might be a safe and effective treatment without zonular or capsular support, long-term follow-up, a large sample size, and many surgeons' involvement are required. J. Natl. Inst.

Background: External dacryocystorhinostomy (DCR) is now a well-established, effective approach to relieve nasolacrimal duct obstruction. Per operative hemorrhage obscure the operative field during surgery.so it is difficult to carry on an uncomplicated surgery. Moreover postoperative hemorrhage has become an added problem. The objective of this study is, to evaluate the effect of oral tranexamic acid in reducing both per operative and postoperative hemorrhage in external DCR surgery. Methods: This hospital based interventional quasi experiment included 60 patients with chronic dacryocystitis at DMCH between January 2014 to June 2014.Oral formulation of tranexamic acid 500mg two capsule and tablet Vit B complex as placebo started 1 hour prior to DCR surgery and continued up to second postoperative day in intervention and control group respectively. In every case, the rate of hemorrhage was evaluated peroperatively and postoperatively. Findings: In this study, mean duration of operation was 35.98 (range 30 to 51) min in group-A and 54.13(45-75min) minutes in group-B. Perioperative mean blood loss was of 15.03 ml with a maximum blood loss of 25ml in group A and was 33.57ml with maximum blood loss of 39ml in group B. Mean postoperative bleeding was 2.55ml with maximum blood loss 5ml In group A and was 5.53ml with maximum blood loss 13ml in group B. postoperatively no bleeding was found in 24(73.33%) cases in group A and 10(40%) cases in group B. Conclusion: This study suggests that oral tranaxemic acid significantly reduces peroperative and postoperative hemorrhage and reduces duration of surgery and improves the quality of DCR surgery.

Purpose: Keratoconus is an ectatic corneal disease characterized by regional thinning and protrusion that leads to irregular astigmatism and, ultimately, substantial vision impairment. The aim of this study was to see if there was a link between serum IgE levels and keratoconus. Methods: At the Combined Military Hospital Dhaka, a prospective observational study was conducted in the general Eye OPD and Cornea clinic. The study involved 60 participants who were divided into 2 groups. Thirty people with keratoconus were assigned to Group A, while 30 healthy people were assigned to Group B. All 60 patients had their serum IgE levels checked. Results: The mean age of the study subjects in Group A and group B were 19.60±5.28 (SD), and 20.23±5.62 (SD) respectively; 13 were male and 17 were female in Group-A, and 10 were male and 20 were female in Group-B. Serum IgE was 243.183±143.059 (SD) in group-A and 86.067±77.065 (SD) in group-B. There was a significant rise in serum IgE in Group-A (p value <0.0001). Conclusion: Elevated serum IgE levels are strongly associated with keratoconus. Measuring serum IgE could be an important parameter in the management of Keratoconus. J. Natl. Inst.
