ABSTRACT
Purpose: To evaluate changes in higher order aberrations (HOAs) induced by implantable collamer lens (ICL) implantation in correction of high myopia and to compare the anterior segment parameters before and after surgery. Also, to correlate these parameters with HOAs, the best corrected visual acuity (BCVA) and intraocular pressure (IOP). Methods: This prospective interventional cohort case series study included 40 eyes with high myopia that underwent ICL V4c implantation. They were evaluated pre-operatively and post-operatively at 1st and 3rd month HOAs using Scheimpflug Sirius Camera. The anterior segment parameters were evaluated by optical biometry. Correlations between HOAs, BCVA and anterior segment parameters were evaluated. Results: The mean pre-operative BCVA was 0.67 ± 0.17, while post-operative BCVA was 0.74 ± 0.16 (p-value < 0.001). The spherical equivalent was -13.66 ± 2.23 pre-operatively, while post-operatively it was -0.77 ± 0.65 (p-value < 0.001). The mean pre-operative root mean square (RMS) of HOAs was 0.62 ± 0.11 µm, while mean post-operative RMS in the 1st month was 0.82 ± 0.29 µm (p-value < 0.001). At 3rd month, it was 0.63 ± 0.17 µm (p-value = 0.685). The mean pre-operative anterior chamber depth (ACD) was 3.66 ± 0.26 mm. It decreased in the post-operative 1st month to 3.46 ± 0.30 mm, while in 3rd month 3.45 ± 0.24 mm (p-value < 0.001, < 0.001) respectively. The mean pre-operative anterior chamber angle (ACA) 45.98 ± 8.39 o while, the mean ACA was 31.65 ± 4.14, 31.03 ± 3.74 post-operatively (p-value < 0.001, < 0.001) respectively. There was significant increase in IOP (p-value < 0.001). Conclusion: ICL implantation is safe and effective in correction of high myopia, as HOAs increase at first month post-operatively then, return to the pre-operative level by 3rd month. However, anterior segment parameters show significant changes which may need longer follow up.
ABSTRACT
BACKGROUND: Epilepsy is a disorder characterized by recurring seizures that do not have an immediate identifiable cause. It is a disorder with complex symptoms and a wide range of risk factors, with age, genetics, and origin being the most prevalent variations. This study aimed to evaluate the knowledge of and attitude towards epilepsy among the Jordanian community. METHOD: An online cross-sectional study using a self-administered questionnaire was conducted between 29 March and 15 May 2022 in Jordan. In this study, three previously validated questionnaire items were adapted and employed. Binary logistic regression was applied to identify predictors of good knowledge and a positive attitude. RESULTS: A total of 689 participants were involved in this study. A weak level of knowledge about epilepsy was observed among the study participants (35.3%). The participants showed a moderately positive attitude towards epilepsy (63.3%). Being female, holding a bachelor's degree, knowing anyone who had epilepsy and seeing anyone having an epileptic seizure were factors that positively affected participants' knowledge about epilepsy. Being aged between 24 and 29 years or being divorced were factors that affected the participants' attitudes negatively towards epilepsy. CONCLUSION: The study's participants had limited knowledge of epilepsy and a favorable attitude toward it. The community's understanding of epilepsy and attitude toward epilepsy patients should be improved by an informed educational effort on the part of various media platforms. All facets of the community, including parents, should be the focus of these initiatives.
