Spontaneous Improvement of Channel Deposits Following Intacs Implantation

PURPOSE: To report a case of filamentous crystalline channel deposits and stromal haze extending outside the channel, which continued to worsen more than 3 years after implantation before eventually improving without significant intervention. METHODS: A 48-year-old woman presented for refractive surgery evaluation. Uncorrected visual acuity was 20/400 in both eyes. Ocular history was significant for mild blepharitis but was otherwise normal. Approximately 4 months after bilateral Intacs (KeraVision) implantation, the patient developed intrachannel deposits in both eyes, which had increased significantly at 3-year follow-up. RESULTS: The intrachannel deposits and haze spontaneously improved, and 9 years following implantation few deposits and little haze remained. CONCLUSIONS: Channel deposits, opacification, and haze are widely reported complications following the implantation of intrastromal corneal ring segments. Such deposits and opacifications are generally not clinically significant and may resolve spontaneously. [J Refract Surg. 2011;27(4):303-305.] doi:10.3928/1081597X-20100804-03
