1例46岁的远视性左眼，屈光度为+ 7.75D/− 1.25D， × 5°，矫正距离视力为20/50，因医疗疏忽误行− 8.50DS/− 1.50 DC × 175°矫正近视散光。取出的晶状体随后被重新植入原位。术后8个月行FS- 矫正远视散光(+ 5.0DS/− 0.75 DC × 100°)。FS-LASIK术后两年，角膜断层扫描未见扩张，显微镜下可见透明角膜。左眼CDVa为20/50，屈光度为− 0.75DS/− 0.25 DC × 165°。结论SMILE晶状体原位植入提供了一种恢复角膜体积和厚度的方法。FS-LASIK为晶状体再次植入术后的屈光不正提供了可行的矫正方法。还需要进一步的研究来确定这种治疗的有效性。
BackgroundThis report describes a case in which hyperopic femtosecond laser-assisted in situ keratomileusis (FS-LASIK) was performed following small incision lenticule extraction (SMILE) lenticule in situ implantation.Case presentationThe hyperopic left eye of a 46-year-old patient with refraction of + 7.75 diopters sphere (DS)/− 1.25 diopters cylinder (DC) × 5° and corrected distance visual acuity (CDVA) of 20/50 mistakenly underwent the SMILE procedure for myopic astigmatism (− 8.50 DS/− 1.50 DC × 175°) due to medical negligence. The extracted lenticule was subsequently re-implanted in situ. After 8 months, the left eye underwent FS-LASIK to correct hyperopia and astigmatism (+ 5.0 DS/− 0.75 DC × 100°). Two years after FS-LASIK, corneal tomography showed no ectasia and microscopy revealed transparent cornea. The left eye exhibited CDVA of 20/50 with refraction of − 0.75 DS/− 0.25 DC × 165°.ConclusionsSMILE lenticule in situ implantation offers a solution for corneal volume and thickness restoration. FS-LASIK provides feasible correction of refractive error following lenticule re-implantation. Future studies are needed for determining the effectiveness of the treatment.
