Abstract:AIM: To investigate the satisfaction and satisfaction score of myopic patients after small incision lenticule extraction(SMILE).
METHODS: Myopic patients treated with SMILE were enrolled from Jan. to Dec.2013 in Henan Eye Institute. The patients were divided into different myopia groups according to spherical equivalent, and were divided into low age group and high age group according to age. The satisfaction survey was performed 18-30mo after SMILE. The differences of response rate and satisfaction score among different myopia groups were performed by Chi-square test and One-way ANOVA, respectively. The differences of satisfaction score between different age groups were performed by sample t-test. The differences of satisfaction score between postoperative symptomatic group and asymptomatic group were performed by sample t-test.
RESULTS: A total of 239 eyes of 120 patients were enrolled. A total of 183 eyes of 92 patients replied, the response rate was 76.6%. The average age was(25.6±5.3)years, the mean preoperative spherical equivalent was(-4.87±1.37)D. The response rates were not statistically significant among different myopia groups(χ2=12.00, P>0.05). The percentage of patients that were very satisfied with surgery was 98.9%, and they would like to recommend the surgery to their families or friends. The satisfaction score of moderate myopia group was significantly higher than that of low myopia group and high myopia group(P<0.05). The satisfaction score of low age group was higher than that of high age group(t=2.95, P<0.05). The incidence of dry eyes, poor night vision, glare and eye discomfort was 15.3%, 9.8%, 7.7%, and 7.1% after operation. The satisfaction score of dry eye was lower than that of asymptomatic patients(P<0.05). There were no significant differences between asymptomatic patients and poor night vision, glare or eye discomfort patients(P>0.05).
CONCLUSION: The satisfaction extent of myopic patients after SMILE is very high. The satisfaction score of moderate myopia group and low age group was high, and the postoperative satisfaction score of dry eye is low.
