Abstract Details

Purpose:

To report outcomes in eyes with intracorneal ring segments (ICRS) and subsequent collagen crosslinking (CXL) procedures for stabilization of keratoconus.

Setting:

Illinois Eye and Ear Infirmary - Chicago Eye Institute. Chicago- IL

Methods:

A multicenter, retrospective study of all eyes implanted with ICRS (Intacs® Oasis, CA.) that underwent subsequent CXL. Segment size implanted were between 350 and 450 microns. Preoperative and postoperative best-corrected visual acuity (BCVA), refraction, intraoperative and postoperative complications, and keratometry values were examined.

Results:

Eleven eyes of 10 patients were included in this study. All eyes first underwent ICRS implantation. Mean age at the time of CXL was 39.7±3.6 years. Mean interval time between ICRS and CXL was 36.5±11.5 months. BCVA was logMAR 0.2 (SD ±0.2) prior to ICRS implantation and logMAR 0.2(SD ±0.08) prior to CXL. Prior to CXL, mean K2 was 50.6± 4.1 D and mean K1 was 47.1 ± 3.6 D, and at last follow up time after CXL was 49.6 ± 5.3 D and 46.4± 2.9 D for K2 and K1 respectively.

Conclusions:

Sequential implantation of femtosecond laser-assisted image-guided intracorneal ring segments followed by collagen crosslinking is safe and effective in select cases of ectatic disorders, particularly when stabilization of the condition is a primary objective.
