Effect analysis of perioperative comprehensive intervention of laser-assisted in situ keratomileusis in myopia patients
Objective To explore the perioperative comprehensive intervention of laser-assisted in situ keratomileusis(LASIK)in myopia patients.Methods 200 patients with myopia were selected for the study and randomly divided into a control group and a study group,with 100 cases(200 eyes)in each group.All patients were treated with laser-assisted in situ keratomileusis,with perioperative conventional interventions in the control group and perioperative comprehensive interventions in the study group.Both groups were compared in terms of visual quality[Strehl's ratio(SR),modulation transfer function cutoff frequency(MTF cutoff),and optical quality analysis system(OQAS)values under 100% contrasts(OV100% ),OQAS values under 20% contrast(OV20% ),OQAS values under 9% contrast(OV9% ),objective scatter index(OSI)],satisfaction with the intervention modality,and incidence of postoperative complications.Results The study group had SR of(0.27±0.09),MTF cutoff of(33.05±5.18)c/deg,OV100% of(1.36±0.41),OV20% of(1.37±0.43)and OV9% of(1.50±0.47),all of which were greater than(0.23±0.02),(30.20±4.26)c/deg,(1.15±0.11),(1.18±0.14)and(1.26±0.21)in the control group;OSI of(0.39±0.08)in the study group was lower than(0.46±0.12)in the control group;the difference was statistically significant(P<0.05).The incidence of postoperative complications of 0.50% in the study group was lower than 12.50% in the control group,and the difference was statistically significant(P<0.05).The total satisfaction rate of the study group 99.00% was higher than that of the control group 75.00%,and the difference was statistically significant(P<0.05).Conclusion Perioperative comprehensive interventions for laser-assisted in situ keratomileusis can reduce postoperative complications,improve satisfaction,and enhance visual quality of patients.
