Abstract Details

Purpose:

To observe the efficacy, safety and predictability of implantable collamer lens (ICL) implantation for correction of myopia after excimer laser corneal refractive surgery.

Setting:

Chongqing Aier Eye Hospital

Methods:

Prospective study. Eight patients (12 eyes) with recurrent myopia (refractive regression or under-correction) after excimer laser corneal refractive surgery were selected for ICL implantation. Semi-deep ICL implantation was performed at least 6 months after each participants’ first excimer laser corneal refractive surgery. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refraction error, intraocular pressure (IOP), corneal endothelial count, and vault were collected before and at 1 day, 1 month, 3 months, and 3 years after ICL implantation. Paired t tests were carried out for statistical analyses.

Results:

The mean follow-up period was 8.17±11.86 m (range, 1 m–7 m). The mean preoperative SE was -5.19±2.76 D. UCVA at the final visit was 4.88±0.24, 83.33% of eyes reached preoperative CDVA or better. The safety index and the effective index were 1.004 and 1.002 at 1 month postoperatively. No significant difference in IOP or corneal endothelial cell density occurred during the follow-up period. Glaucoma and ghosting occurred in 3 eyes, visual fatigue occurred in 3 eyes, and 2 eyes had difficulties in near vision. No cataracts, retinal detachment or other serious complications were observed.

Conclusions:

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.
