To observe the efficacy, safety and predictability of implantable collamer lens (ICL) implantation for correction of myopia after excimer laser corneal refractive surgery.
Prospective study. Eight patients (12 eyes) with recurrent myopia (refractive regression or under-correction) were selected for ICL implantation. Visual acuity, refraction, intraocular pressure, corneal endothelial count, and vault were collected before and at 1 day, 1 month, 3 months, and 3 years after ICL implantation. The mean follow-up period was 8.17±11.86 m (range, 1 m–7 m).
Before the operation,the mean UCVA(Uncorrected Visual Acuity) was 4.16±0.35 and mean BCVA（Best Corrected Visual Acuity ）was 4.87±0.14.At 1 month follow-up,the mean UCVA was 4.90±0.21, better than preoperative UCVA（t=-6.230,p＜0.01）,reaching 83.33% (10/12) of preoperative BCVA or better; The safety index was 100.41% and the effective index was 100.21%.The mean arch heights at 1 month follow-up was (441.82±349.34)um. No serious complications were observed.
The safety, efficacy, and predictability of ICL in the correction of myopia after excimer laser corneal refractive surgery are remarkable. However, its long-term stability needs further observation.
