To contend the market in the existent state, cost efficacy is vastly desired. For that, productivity improvement technique is among the many ways [1]. Submerged Arc Welding (SAW) is used as a productivity improvement method in the present paper where manufacturing process of fabricated parts are not only curtail by tumbling the process time, moreover by strengthening the weld quality too. Efforts are initiated to improve the productivity of the fabrication department of one of the industrial set up under study is taken by achieving the tensile strength of the weld bead in single pass only. In this process, conventional flux is supplemented by alloying in variations to achieve the optimal tensile strength, which are further verified by one of the optimisation method. The effect of input parameters are analysed over the output response and observed that one parameter has more substantial effect on the tensile strength than the other remaining parameters.Keywords

Background: Suturing of conjunctival graft is a traditional technique for pterygium excision surgery. Owing to its many disadvantages & complications many newer techniques like autologous fibrin glue have been introduced & accepted as an alternative method of graft adhesion. Methodology: The present study was conducted at the Department of Ophthalmology, MMIMSR, Mullana (Maharishi Markandeshwar Deemed to be University) in the time period extending between December 2017 and January 2019. 100 eyes of patients of either sex with primary pterygium were selected and divided into 2 groups of 50 each in Group 1- patient underwent conjunctival auto graft with 10-0 ethilon sutures while in Group 2 suture less conjunctival auto graft was done with patient’s own blood fibrin. Results: Parameters such as mean operating time, presenting complaints like pain, watering, burning and foreign body sensation, complications & recurrence were compared between the two groups on postoperative Day 1, Day 7, 2 weeks, 1 month, 2 month, 3 month & 6th month. Statistical significant difference (p<0.01) was found between the suture and sutureless surgery for pterygium in relation to post-operative discomfort grading. There was a significant difference (t = 22.149, p = 0.001) in the duration of surgery for GROUP I surgery. Conclusion: Conjunctival auto graft with autologous serum is a safe and fast method. It is equally effective as conventional sutured autograft technique. Post operative discomfort is significantly less in this method. It also prevents suture related complications.Keywords

Aim: To study postoperative outcome & related complications of Glue free and suture free conjunctival autograft in pterygium excision in Haryana-A North Indian state. Materials and Method: The present study was conducted at the Department of Ophthalmology, MMIMSR, Mullana (Maharishi Markandeshwar Deemed to be University) in the time period extending between December 2017 and January 2019. 50 eyes of patients of either sex with primary pterygium were selected and pterygium was excised & sutureless & glue free conjunctival autograft was done with patient’s own blood fibrin. Parameters such as mean operating time, presenting complaints, grade, complications & recurrence were observed on postoperative Day 1, Day7, 2 weeks, 1 month, 2 month, 3 month & 6th month. Results: The mean age of the study population was 48.82 + 11.13 years... Out of 50 eyes only 1 (2%) had conjunctival cyst, 2 (4%) graft edema and 3 (6%) had graft displacement, 1(2%) had graft lost, 1(2%) had graft rejection & 1(2%) had recurrence at 6 month follow up. The mean operation time was 24.88 minutes. Regarding type of the pterygium, out of 50 patients 9(18%) were grade 1, 26(52%) were grade 2, 11(22%) were grade 3 and 4(8%) were grade 4. Conclusion: Conjunctival autograt using patients own blood technique is a safe, cheaper, effective, with less surgical time & has minimal postoperative discomfort.Keywords
