Impact of Nursing Care on Curative Effect of SMILE Operation for Moderate Myopic Astigmatism
Objective To study the impact of nursing on the curative effect of SMILE surgery for moderate myopia correction.Methods Totally 60 patients(120 eyes)of myopia and astigmatism given SMILE surgery between Mar.2024 and Sep.2024 were selected.According to the degree of astigmatism before the operation,they were divided into a low astigmatism(-0.75～-1.50)group(38 patients,76 eyes)and a moderate astigmatism(-1.75～-3.00)group(22 patients,44 eyes).All the patients were given perioperative psychological nursing.Three months after the surgery,the uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),equivalent spherical(SE),keratometry(K),surface reguiarity index(SRI),target induced correct astigmatism(TIA),surgical induced correction for astigmatism(SIA),difference vector(DV),correction index(CI)and index of success(IOS)of the patients in both groups were detected and compared.Results Three months after the surgery,UCVA increased significantly in all the eyes,reaching or exceeding the preoperative BCVA,and the difference between the two groups was significant(P＜0.05).The postoperative average cylindrical degree of the low astigmatism group and moderate astigmatism group was(-0.39+0.2)D and(-0.65+0.3)D respectively,and the difference was statistically significant(t=2.583,P=0.014).The predictability of astigmatism in the low astigmatism group and moderate astigmatism group was(y=0.78x+0.023,R2=0.734)and(y=0.87x-0.18,R2=0.525)respectively.On average,for every ID of astigmatism,the less correction was about 8％for moderate astigmatism and 13％for high astigmatism.There was no significant difference in DV between the two groups(P＞0.05).For both groups,the eye astigmatism correction showed an owing trend,and the correction owed in the low astigmatism group(CI=0.87)and moderate astigmatism group(CI=0.85)was 13％and 15％respectively,indicating the difference that was not significant(P=0.835).The difference between the two groups in IOS was not great(P=0.835).After the perioperative psychological nursing,7 patients(18.4％)in the low myopia group and 4 patients(18.2％)in the high myopia group experienced visual discomfort during the surgery.There was no statistically significant difference between the two groups(P＞0.05).Three months after the surgery,3 patients(7.90％)in the low myopia group and 2 patients(9.01％)in the high myopia group experienced visual discomfort.There was no statistically significant difference between the two groups(P＞0.05).Conclusions SMILE is safe and effective in the correction of mild and moderate myopic astigmatism.Although the degree of astigmatism is partially uncorrected,the surgical predictability is good,and SMILE has a good correction effect for mild and moderate myopic astigmatism.
