AIM: To evaluate the efficacy, safety and stability of Crystal replacement after implantable contact lens(ICL).

METHODS: The research was based on the retrospective analysis of 9 patients(10 eyes)who underwent Crystal replacement after ICL surgery in Wuhan Aier Eye Hospital during March 2012 to August 2012, because of their vault had raised, including 2 males(2 eyes)and 7 females(8 eyes). All patients were followed-up for 3-6 months. The visual acuity, peripheral anterior chamber angle, anterior chamber volume, intraocular pressure, pupil size, vault, glare sensitivity, endothelial cell morphometry, as well as lens opacities were observed.

RESULTS: After operation, naked visions of the 10 eyes were better than or equal to preoperative corrected vision. Peripheral anterior chamber angle and anterior chamber volume was significantly increased. Vault returned to normal. The glare sensitivity was relieved obviously. Pupil size returned to the preoperative level at 6 months after surgery. The intraocular pressure and corneal endothelium counting before and after the operation had no significant difference. No case of lens opacities had happened. No serious complication was detected during the follow-up.

CONCLUSION: The choose of Crystal replacement after ICL had been shown to have the great efficacy, safety and stability, which can effectively solve the problem of spring height after ICL, and greatly improve the postoperative vision correction effect and patient satisfaction.
