摘　　要：AIM:To compare the clinical outcome of small-incision lenticule intrastromal keratoplasty(s LIKE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK)for correction of moderate and high hyperopia.METHODS:A case-controlled clinical study was performed.Twenty right eyes of 20 moderate and high hyperopia patients underwent s LIKE(s LIKE group)and 22 right eyes of 22 moderate and high hyperopia patients underwent FS-LASIK(FS-LASIK group)were enrolled in this study from October 2015 to October 2017.Visual acuity,refractive error,corneal thickness,and keratometry were compared between the groups before and 1 y postoperatively.RESULTS:The postoperative uncorrected near visual acuity(UNVA)and uncorrected distance visual acuity(UDVA)were improved in the two groups.The UNVA reached J1 in 15 eyes(75.0%)in the s LIKE group and 5 eyes(22.7%)in the FS-LASIK group 1 y after surgery(χ2=11.476,P=0.001).The UDVA was equal or better than the preoperative CDVA in 16 eyes(80.0%)in the s LIKE group and 8 eyes(36.4%)in the FS-LASIK group,respectively(X2=8.145,P=0.004).No eyes lost any line of best-corrected visual acuity(BCVA)in either group.The amount of postoperative residual hyperopia in the s LIKE group was significantly less than in the FS-LASIK group(Z=-2.841,P=0.004).The postoperative keratometry and corneal thickness were significantly higher in the s LIKE group than in the FS-LASIK group(t=4.411,10.279,P<0.001).The SRI and SAI of the s LIKE group were significantly higher than that in the FS-LASIK group.There was no statistically significant difference in mean decentration between the two groups.CONCLUSION:s LIKE has better visual and refractive outcome than FS-LASIK for correction of moderate and high hyperopia.
