Abstract Details
Purpose:
The purpose is to asses the intraestromal corneal ring segment (ICRS) as an option to avoid or delay the need of corneal trasplantion in pediatric patients with advanced keratoconus
Setting:
Larcovision Eye Clinic and Surgery, Quito, Ecuador
Methods:
This retrospective study include pediatric patients between ages 8 to 17 years old with advanced keratoconus and poor corrected distance visual acuity (CDVA) that underwent ICRS implantation with femtosecond laser for the creation of a corneal tunnel under topical anesthesia. In none of the cases cross-linking (CXL) procedure was done. Data was obtained from preoperative and postoperative controls at 6th and 12th month. Statistical analyses were performed with a commercially available software package (SPSS for Mac, Version 20.0; IBM Corporation, Armonk, NY, USA). For all statistical tests, a p-value of less than 0.05 was considered as statistically significant.
Results:
36 eyes of 33 patients with mean age 14.9 years were enrolled. CDVA mean at the 6-month follow-up, improved from 0.86 ± 0.67 logMAR to 0.30 ± 0.32 logMAR (P .005); spherical equivalent as well as keratometry mean readings decreased from -5.68D to -3.60D and 52.27D ± 5.39D to 49.58D ± 5.46D, respectively. In the 6-month follow-up, all cases shown stability, that is why CXL wasn't effected, also because some cases the corneal pachymetry was under 400μm. Patients didn't present intraoperative or postoperative complications, except 2, one suffered a corneal microperforation; the other suffered exposure of part of the ring.
Conclusions:
The implantation of intrastromal corneal rings is a safe and effective that grants stability, improves vision and could be an option to avoid or defer a transplant cornea in children
