Abstract Details

Purpose:

To observe the efficacy, safety, and predictability of implantable collamer lens (ICL) implantation combined with corneal laser surgery to correct extreme myopia.

Setting:

Chongqing Aier Eye Hospital

Methods:

This retrospective study included a total of 7 patients (13 eyes) with spherical equivalent refractive error (SE) ≥-16.0D. ICL surgery was performed to correct most of the refractive errors. Over 3 months later, the remaining refractive error was corrected by corneal laser surgery. Comparison of ICL preoperative and corneal laser surgery was performed 1 day, 1 week, 1 month, and over 8 months postoperatively. Visual acuity, vault, intraocular pressure, corneal endothelial cell density, and other indicators were evaluated. The mean preoperative SE was -21.15±2.70 D, and the mean follow-up period was 28.7±17.9 m (8 m–5.5 y).

Results:

Mean SE was -1.46±0.77 D at the last examination. The combined surgical efficacy index and safety index were 1.02 and 1.03, respectively. A total of 84.62% of eyes were within ± 1.0 D of the predicted SE, 61.54% were ±0.5 D. We compared these values to preoperative CDVA. A gain of 1 line of UDVA was seen in 3 eyes, and a gain of 2 or more lines of UDVA was seen in 5 eyes (61.54%, 8/13). One eye suffered retinal detachment (8 months after the operation), 4 eyes suffered glare and halo, and 3 eyes had dry eye symptoms.

Conclusions:

Posterior chamber intraocular lens implantation combined with corneal laser surgery was found to be a safe, effective, and predictable method of correcting extreme myopia.
