Assessment of Optometrists’ Knowledge, Skills and Practice on Cataract: A Cross-Sectional Study from Kisumu County, Western Kenya
Abstract Background: Cataract is a major contributor to avoidable blindness in the world and greatly impact negatively on the quality of life. The prevalence of blindness in Kenya is estimated at 0.7% with cataract contributing 43%. Optometrists being the primary eye care providers for cataract patients, they are well placed to assess and refer cataract patients. Though there is no data on optometrist knowledge, skill and practice on cataract in Kisumu, Kenya. Methods: A cross-sectional study design was used. The study was conducted from June 2019 to August 219 using self-administered questionnaire. We collected basic socio-demographic characteristics and investigated participants’ knowledge, skills and practice on cataract. The primary outcome measures were the proportions of participants who identified the questions related to knowledge, skills and practice on cataract. Chi-square analysis was performed to look at the association between demographic and practice, knowledge and skills. Results: A total of 49 optometrists were interviewed with a male to female ratio of 2:1, mean age of 30.4(72%) years and mean duration of practice of one to ten years. Majority of the optometrists had good knowledge on various aspects of cataract. Like 98% had a good knowledge on the types of cataract. Based on skills, 75.5% could diagnose cataract correctly. However, 57.1% could not identify nuclear cataract. Practice among the optometrists was largely low in the sense that, 61.2% of optometrists did not screen patients aged 40 years and above for cataract. Almost half of the optometrists, 52.6% did a routine eye examination but did not know the importance of examining the crystalline lens for patient above 40 years. Conclusion The study established that despite the good level of knowledge among the optometrist on cataract, there exist gaps in skills in categorizing the type of cataract and practice. The results of this study calls for skills development training for optometrists on cataract and immediate ophthalmic division response for improvement on the scope of training for optometrists. This will eases diagnosis of cataract and its management so as to reduce its burden in Kenya.
