Abstract

Introduction: To evaluate the prevalence and the factors associated with Computer Vision Syndrome. Materials and Methods: This cross-sectional, descriptive, questionnaire based, non–randomized study included 320 professionals. After obtaining written consent subjects were asked to fill a set of questionnaire to get their personal information including demographic data (age, gender, occupation) and information regarding computer usage. Results: A total of 320 participants aged between 16 to 55 years were surveyed. The prevalence of symptoms of CVS was found to be 70.3%. 97 (33%) individuals used computer around 4-6 hours per day. The most frequently observed symptom was headache seen in 176 individuals (55.1%) followed by neck, shoulder, wrist or back pain in 155 (48.5%), dryness of eyes in 128 (39.9%) & blurred vision in 118 (36.9%) individuals. 42 participants (12.4%) were aware of CVS. 261 participants (81.6%) took preventing measures and the most common preventive measure was taking breaks in between work. Conclusion: Around 70.3% of surveyed participants experienced symptoms related to CVS. Out of 320 participants only 42 participants (12.4%) were aware of CVS. Some of the strategies found beneficial in reducing the symptoms are keeping the computer screen away which reduces eye strain, taking regular small breaks, maintaining good sitting posture to avoid neck pain and back pain, correction of visual problems and optimum room lighting. Keywords: Blurred vision, Computer vision syndrome, Dry eye, Eye strain, Headache.

Abstract

Purpose: To analyze and determine the postoperative visual acuity and complications after intraocular implantation of an iris-claw lens in aphakic patients. Setting: Sri Devaraj Urs Medical College, Kolar, Karnataka, India. Design: Retrospective study. Materials and Methods: Medical records of cataract and aphakic patients who underwent posterior fixation of iris claw lens over a five-year period were reviewed for collection and analysis of data. Results: The study comprised 138 eyes of 57.25% female and 42.75% male with mean age of 62.84 ± 8.649 years. The follow up period was 6 to 24 months. The mean preoperative CDVA was 0.44 + 0.23 logMAR. After 1 year of follow up period the mean postoperative CDVA was 0.3+ 0.15 logMAR which was statistically significant (p Conclusions: This study showed the merits of retrofixated iris claw lens over AC IOL and SF IOL in terms of simple technique, short learning curve, satisfying overall visual outcome, less risk of complications and good safety profile. Keywords: Aphakia, Enclavation, Iris claw, Retrofixation.
