Abstract

Introduction: Limbal Relaxing Incisions (LRI) is a surgical technique used to correct astigmatism during cataract surgery. This technique used to reduce the steepness of the corneal curvature in a particular meridian. LRI can be performed alone or in combination with phacoemulsification.  Methods: This prospective study aimed to investigate the effect of Limbal Relaxing Incisions (LRI) on corneal astigmatism in patients who underwent phacoemulsification cataract surgery. Five patients were included in this study, and preoperative and 1-week postoperative keratometry values (K1=flat keratometry and K2=steep keratometry) were measured using the IOL Master. Paired t-test analysis was used to compare the changes in K1 and K2 values before and after LRI.  Results: Five patients with the mean age 39.8 years (range: 22 to 76 years) and corneal astigmatism 3.12 D (range: 2.25 to 4.66 D) were underwent LRI and cataract surgery. The mean preoperative K1 and K2 values were 42.12 D and 46.44 D, respectively, while the mean 1-week postoperative K1 and K2 values were 42.60 D and 45.80 D, respectively. Paired t-test analysis showed a statistically significant decrease in K2 values (p = 0.025) but no significant change in K1 values (p = 0.329).  Conclusion: This study showed there were no significant difference between pre and postoperative of K1 and showed a significant decrease in K2 on IOL Master examination. The wide age range of the included patients may have influenced the effectiveness of LRI in reducing astigmatism. Further study with more subjects are required.

Abstract

Introduction and Objective: The COVID-19 pandemic has virtually made many work activities, resulting in increased use of Visual Display Terminals (VDT) at work and home. Excessive close-range activities due to the use of VDT causes Computer Vision Syndrome (CVS). Various therapies, such as ocular yoga and warm compress, have been created to reduce CVS-related complaints. Diponegoro University developed “Senam PERMATA-KU” as an alternative therapy to reduce complaints related to CVS. This study compares the effect of “Senam PERMATA-KU” and periocular warm compress on the amplitude of accommodation (AA) value in patients with CVS. Methods: The study subjects were divided into “Senam PERMATA-KU” group (22 people) and periocular warm compress group (20 people) with each treatment for two weeks. CVS score was measured using CVS-Questionnaire and AA using Prince’s rule. Both variables were assessed before and after treatment. Data were collected and analyzed using a statistical computer program. Result: “Senam PERMATA-KU” group experienced a significant increase in monocular and binocular AA (p<0.001 and p=0.006), while periocular warm compress did not show a significant difference (p=0.982 and p=0.483). The mean delta of monocular and binocular AA between groups differed significantly (p=0.001 and p=0.034). The mean CVS scores in both groups have significant improvement (p<0.001), while the mean delta CVS scores between groups was not significant (p=0.522). Conclusion: “Senam PERMATA-KU” for two weeks significantly increased monocular and binocular AA, while periocular warm compress showed no significant difference. “Senam PERMATA-KU” and periocular warm compress can significantly reduce CVS score, whereas the difference between the two is insignificant.
