Abstract

Aim: To evaluate the causes of small pupil and its intra-operative complications in SICS. Materials and Methods: A total of 50 patients presenting to OPD with Small pupil measured after maximal dilation using tropicamide (0.5%) with phenylephrine (1%) e/d administered 4 times at 15 minutes interval were enrolled in this study. Detailed clinical history, prior medication, presence of possible risk factors, underlying co-morbidities and history of trauma were noted for every case. Results: The results drawn from the study out of 50 patients, revealed that 14 cases were associated with Pseudo-exfoliation syndrome, 16 cases with posterior synechiae (11 were associated with chronic uveitis And 5 cases had history of Trauma), 12 cases were associated with DM, 2 patients had history of intraocular surgery, 1 patient was on Tab. Tamsulosin for treatment of BPH. The remaining 5 cases were atonic pupil in old age patients. Conclusion: The current study discusses the causes of Small pupil and its intra-operative complications along with its management. It’s crucial for every cataract surgeon to cope with small pupil manifesting preoperatively and intra-operatively. Keywords: Tamsulosin, Synechiae, Tropicamide

Abstract

Aim of the study: Study of comparison of postoperative astigmatism in small incision cataract surgery depending on size and shape of incision Materials and Methods: A prospective study of 50 eyes of 50 patients who underwent manual SICS under local anaesthesia between December 2020 and May 2021 conducted by single surgeon and followed up on post op day 1 day 7 and 6 weeks. Patients selected were having grade 1 to 2 nuclear sclerosis the size and shape of incision was decided depending upon the grade of cataract. On follow ups thorough ocular examination was done especially looking for corrected visual acuity and correction needed for that. Keratometry was done in each follow up visits. At the end surgically induced astigmatism (SIA) was calculated. Results: Surgically Induced Astigmatism (SIA) calculated by SIA calculator SIA was 0.5 - 1 D in 38 patients with frown incision of 4 to 5mm,1.0 - 1.5 D in 10 patients with frown incision size of 5 to 6mm 2D in patients with straight incision size of 6mm and more In all cases. Conclusion: The less average SIA was noted in group with smaller incision of about 4 to 5mm. Frown superior incision has got added advantage of early wound stabilization than straight incision. It is possible to reduce the amount of post-operative astigmatism significantly by choosing the incision shape and size.   Keywords: Surgically induced astigmatism, Manual small incision cataract surgery

Abstract

Purpose: Computer and video display users complain of eye irritation due to changes in tear film and decreased blink rate .Therefore purpose of this study was to know the prevalence of dry eye in computer users. Materials and Methods : A prospective study was done in 120 eyes of 60 clerical staff working on computer for more than 4 hours/day in a medical college. A detailed ocular examination with assessment of dry eye was done with TBUT, SCHIRMER’S test, tear meniscus height and a questionnaire about dry eye. Results : The prevalence of dry among computer users of this group was found to be 18%. Conclusion: Prevalence of dry eye is increasing in the computer users. We also created awareness about dry eye among them. Keywords: Dry eye, TBUT, SCHIRMER’S test.
