Comparison of the Quality of Life in Patients with Eye Diseases Before and After Surgery (A Comparative Study: Patients with Strabismus and Keratoconus)

 Based on the definition of quality of life-related to vision based on patients' understanding of vision and their daily problems, this study examines patients' problems and quality of life-based on their judgments. 

 The research method used was a descriptive "prospective cohort" type. Two groups of patients were followed up for six months, and information was collected from them. The study population was all patients referred to Farabi Hospital for two months who were suffering from strabismus and keratoconus. A simple random sampling method was used to recruit strabismus patients while all keratoconus patients were recruited. First, the quality of life of both groups of patients was checked before the surgery. Then after the surgery, it was re-evaluated in three months and six months (the third month and the sixth month after) to check whether the surgery was effective.

 Explanatory and analytical findings showed a significant difference in the variable score of quality of life and its dimensions before and after surgery in strabismus patients. Also, the quality of life of strabismus patients has grown significantly after three months of surgery compared to before surgery. Also, Analytical findings related to examining the difference in the quality of life and its dimensions in patients with keratoconus showed no significant difference in the variable score of quality of life and its dimensions before and after surgery.

 Strabismus patients were satisfied with the surgery, and this had a very positive effect on their life. Although the score and the average quality of life in these patients increased slightly after the operation compared to before the operation, this increase in the quality of life score was not enough to significantly increase their satisfaction and quality of life.
