Assessment of optometrists’ knowledge, skills and practice on cataract: a cross-sectional study from Kisumu County, Western Kenya

Abstract

Background The quality of life can be impacted negatively by blindness arising from cataract. The total prevalence of blindness in Kenya is estimated at 0.7%, however cataract contributes almost half (43%) of the total blindness in Kenya. Optometrists are well placed to assess and refer cataract patients. However, little is known on optometrists’ skills, practice and knowledge. Therefore, this study was designed to assess optometrists’ 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. Basic socio-demographic characteristics were collected and participants’ knowledge, skills and practice on cataract were investigated. The primary outcome measure was the proportions of participants who identified the questions related to knowledge, skills and practice on cataract. Chi-square analysis was performed to assess the association between demographic characteristics of participants with practice, knowledge and skills. Results A total of 49 optometrists with a mean age of 30.4 years and mean duration of practice of 1–10 years were interviewed. Most optometrists had good knowledge on various aspects of cataract. For example (98%) had a good knowledge on the types of cataract. Almost three quarter (75.5%) of the optometrists reported that they could diagnose cataract correctly based on skills. However, half (57.1%) of the optometrists could not identify nuclear cataract. Being a self reported practice and not an observed practice, most optometrists (61.2%) reported that they did not screen patients aged 40 years and above for cataract. Almost half (52.6%) of the optometrists reported that they did a routine eye examination however, they could not justify the significance of examining the crystalline lens for patient above 40 years. Conclusion The study established that despite the good level of knowledge among optometrist on cataract, there exist a gap on skills and practice. The results of this study calls for more clinical based activities among optometrists. This will eases diagnosis of cataract and its management with an aim to reduce the burden in Kenya.

Impact of professional wrangles among eye care providers in Kenya on refractive error service delivery

“…The results from the study also pointed out on specialty as a source of wrangles existing among eye care providers in Kenya. The existing eye care providers consist of ophthalmologists who are to conduct comprehensive ocular examination and offer surgical correction when need be, optometrists who are well placed to handle optic issues of the eye ranging from detection to management of refractive error services speci cally, ophthalmic clinical o cers who were trained to ensure that cases of cataract 14 are addressed and ophthalmic nurses who assist ophthalmologists during procedures. The description of the roles places optometrists to be more conversant and majorly focused on refractive error.…”
