Intrastromal corneal ring segments followed by PRK for postkeratoplasty high astigmatism: prospective study

“…16,17,21–30 Therefore, studies regarding the association of several different techniques have been published with promising results. 23,36,37…”

“…16,17,[21][22][23][24][25][26][27][28][29][30] Therefore, studies regarding the association of several different techniques have been published with promising results. 23,36,37 This article aims to assess the outcomes of the association of ICRS and PRK for the treatment of high PKA.…”

Safety and efficacy of a laser refractive procedure in eyes with previous keratoplasty: systematic review and meta-analysis

“…Included studies were published between 1992 and 2022; 23 were prospective clinical trials and 8 were retrospective. 4,15,16,24–52 Almost all studies had 1 treatment arm, except the study by Huang et al, which had 2 arms. 36 Six studies were conducted in the United States; 5 in Brazil; 4 in Canada; 3 in Italy; 3 in Turkey; 3 in Germany; and 1 each in Australia, Egypt, Iran, Japan, Korea, England, and Spain.…”

“…Twenty-three studies reported patients' sex; the percentage of female patients was 43.6% of the total number of participants. 4,15,16,24,[26][27][28][29][30][31][32][33][35][36][37][39][40][41][43][44][45][46][47]49,50,52 Follow-ups ranged from 1 month to 56 months. Seventeen studies performed LASIK; 12 studies performed PRK, of which 2 performed additional refractive procedures (PTK, intrastromal corneal ring segments) and 1 performed laser-assisted subepithelial keratectomy (LASEK) on a comparison group.…”
