Background: Cataracts are opacities in the lens of the eye that scatter light, frequently compromising vision and impacting persons across all age groups. Pediatric cataracts, especially congenital or infantile (occurring within the first year of life), are the most severe cases. Aim of the study: to evaluate the effect of nursing program on nurses' performance for children undergoing cataract surgery. Research design: A quasi-experimental research design was used. Setting: The study was conducted at Ophthalmology Minia University Hospital – Minia governorate – Egypt. Sample: A convenient sample of all available nurses (46 nurses) who were providing direct pre- and post-operative care to children undergoing cataract surgery. Tools: two tools were used; Tool (I): A structured interview questionnaire covering the demographic characteristics of the studied nurses and nurses' knowledge. Tool (II): Observational checklist form. Results: the total nurses' performances increased post nursing program than pre-nursing program regarding cataract surgery with statistically significant differences. In addition, no statistically significant differences was found between total practice levels and demographic data of the studied nurses pre nursing program. Conclusion: Applying the designed nursing program could significantly improve knowledge, preoperative practice, and postoperative practice of nurses, which consequently led to improvement of the quality of the nursing care. Recommendation: Ophthalmic nurses should receive periodic training programs to improve, update and refresh their performance regarding pediatric cataract.
