Cases were divided into 2 groups; the first group had been treated with femtosecond laser-assisted ICRS (Keraring) implantation accompanied or followed by TE-ACXL, while the second group had been treated by TE-ACXL only and all cases completed a follow-up period of 3 years.Results: In group 1: the mean uncorrected (UCVA) and best-corrected (BCVA) visual acuity, spherical equivalent, K-max and Q-value improved markedly from 0.97 ± 0.19, 0.67 ± 0.18, −8.75 ± 4.55, 60.41 ± 4.98, and −1.18 ± 0.54 preoperatively to 0.61 ± 0.27, 0.39±0.21, −3.25 ± 3.56, 55.22 ± 5.72, and −0.44 ± 0.68 postoperatively respectively. While in group 2: the preoperative mean UCVA, BCVA, spherical equivalent, K-max and Q-values were 0.68 ± 0.28, 0.38 ± 0.24, −2.84 ± 2.59, 50.29 ± 4.04, and-0.58 ± 0.23 respectively while their corresponding postoperative values were 0.58 ± 0.34, 0.19 ± 0.17, −2.35 ± 2.07, 49.58 ± 3.26, and −0.57 ± 0.25. Only one case in group 1 required repeat cross-linking.Conclusion: Although the long-term safety and efficacy of femtosecond laser-assisted ICRS implantation accompanied or followed by TE-ACXL in children with keratoconus and VKC is high, some cases still may need repeat cross-linking.Keywords: accelerated transepithelial cross-linking, Keraring, pediatric keratoconus, spring catarrhAbozaid MAHassan AAAAbdalla ADove Medical Pressarticleaccelerated transepithelial cross-linkingkeraringpediatric keratoconusspring catarrh.OphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 2151-2157 (2019) |
