To report the results of intrastromal corneal ring segment [ICRS] (355º KeraRing; Mediphacos, Belo Hori- zonte, Brazil) implantation in keratoconic patients.
Ophthalmology Department, Bina Eye Hospital Research Center, Tehran, Iran
In this prospective study,Ten keratoconic patients (10 eyes) who underwent ICRS insertion (355º KeraRing) and completed at least 3 months of follow-up were included in this study. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, topographic findings, and adverse events were assessed.
No intraoperative and postoperative complications were demonstrated in this series of patients. At the last postoperative examination, there was a statistically significant reduction in the spherical equivalent refractive error compared with that observed at the examination before implantation (mean ±standard deviation, -2.7±1.8 diopters [D; range, -1.5 to -6.5 D] to -0.6±0.8 diopters [D;range, -1.5 to 0.5 D]; P = 0.027). The The mean preoperative UCVA (logMAR) before implantation was 0.74±0.25 (range, 0.5 to 1.0), whereas at the last follow-up examination, had a UCVA of 0.48±0.16 (range, 0.3 to 0.7). The mean preoperative BSCVA (logMAR) before implantation was 0.33±0.18(range 0.22 to 0.7, whereas at the last follow-up examination had a BSCVA of 0.24±0.10 (range 0.15 to 0.4). No late postoperative complications were observed during the follow-up period.
ICRS (355º KeraRing) implantation is a minimally invasive procedure for improving visual acuity (both UCVA and BSCVA) in keratoconic patients. FINANCIAL INTEREST: NONE
