摘 要：Background:To evaluate the efficacy of manual mid-stromal dissection in stabilizing progressive ***:Surgeries were performed in 16 eyes of 14 patients with progressive *** eyes were examined before and at 1 day,1 week,1,3,6 and 12 months after surgery,and every 6 months ***(simK,Kmax and pachymetry),best corrected visual acuity(BCVA)and subjective refraction were recorded up to the latest follow-up visit(mean follow-up time 6.6±2.4 years).Results:All surgeries were uneventful,and no postoperative complications *** values(n=15)stabilized in 6/11 eyes(55%)with a preoperative Kmax60 D showed continued *** 11/15 eyes(73%)pachymetry was *** with spectacles remained stable in 7/12 eyes(58%)and improved≥2 Snellen lines in 5/12 eyes(42%).BCVA with a contact lens remained stable in 4/9 eyes(44%),improved≥2 Snellen lines in 3/9 eyes(33%)and deteriorated in 2/9 eyes(22%).Conclusions:Manual mid-stromal dissection was effective in 50%of keratoconic corneas with Kmax values60 D and may be considered in cases ineligible for other interventions such as UV-crosslinking,stromal ring implantation or Bowman layer *** advantage of the procedure may be that the tissue is unaltered and that no synthetic or biological implant is required.
