All patients had been subjected to complete preoperative and postoperative ophthalmological examinations — unaided VA, BCVA, refraction, Pentacam, and contrast sensitivity examinations at 3-month, 6-month, and 1-year follow-ups.Results: Mean unaided VA had changed significantly from 0.649± 0.239 logMAR preoperatively to 0.514± 0.222 (P=0.014), 0.419± 0.162 (P< 0.001), and 0.379± 0.142 (P< 0.001) logMAR at the three follow-up visits, respectively. Mean BCVA had changed significantly from 0.326± 0.144 logMAR preoperatively to 0.231± 0.140 (P=0.006) at 1-year follow-up. Mean spherical equivalent refraction had decreased significantly at 6-month (P=0.0298) and 1-year follow-up (P=0.0081). Mean steep keratometry (K2) had also significantly reduced from 51.89± 3.81 D to 49.87± 4.57 D (P=0.034) at 6 months and 49.40± 4.39 D (P=0.011) at 1 year. Mean refractive and keratometric astigmatism had significantly decreased at all follow-up visits.Conclusion: At 1-year follow-up, keraring intrastromal corneal ring–segment insertion assisted by femtosecond laser performed simultaneously with corneal collagen cross-linking resulted in an improvement in visual, refractive, and topographic outcomes, which may suggest it is an effective treatment of keratoconus.Keywords: keratoconus, corneal collagen cross-linking, Pentacam, ICRSEl-Massry ARashid KSaad SOsman IDove Medical Pressarticlekeratoconuscorneal collagen cross-linkingpentacamicrsOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 4447-4453 (2021) |
