PURPOSE
Intrastromal corneal ring segments (ICRS; Intacs) were inserted in a patient with residual myopia of -3.375 D (spherical equivalent) 10 months after laser in situ keratomileusis (LASIK).
METHODS
A standard intrastromal corneal ring segment implantation technique was used with the addition of intraoperative ultrasonic pachymetry in 4 quadrants at the 7-mm zone to insure adequate stromal thickness for segment insertion.
RESULTS
Four months after ICRS surgery and 14 months after LASIK, the patient had uncorrected visual acuity of 20/20 and a cycloplegic refraction of plano -1.00 x 23 degrees.
CONCLUSION
Implantation of intrastromal corneal ring segments in an eye with previous LASIK resulted in additional corneal flattening with a decrease in residual myopia and improved uncorrected visual acuity.
目的
在准分子原位角膜磨镶术（LASIK）后10个月，为一名残余近视-3.375 D（等效球镜）的患者植入角膜基质环片（ICRS；Intacs）。
方法
采用标准的角膜基质环片植入技术，并在7毫米区域的4个象限术中增加超声测厚，以确保有足够的基质厚度用于环片植入。
结果
ICRS手术4个月后及LASIK手术14个月后，患者的裸眼视力为20/20，睫状肌麻痹验光结果为平光-1.00×23度。
结论
在先前接受LASIK手术的眼中植入角膜基质环片可导致角膜进一步变平，残余近视度数降低，裸眼视力提高。
