Abstract Details

Purpose:

mplantable Collamer Lens V4b model for moderate and high myopia: one year follow-up.

Setting:

Fernandez-Vega Ophthalmological Institute, Oviedo, Spain

Methods:

Uncorrected (UDVA) and corrected distance visual acuity (CDVA), refraction, ICL vault and adverse effects were evaluated 12 months after ICL V4b implantation in 121 eyes of 68 patients

Results:

Twelve months postoperatively, the mean spherical equivalent dropped from -7.73 diopters (D) ± 3.33 (range -1.37 to -17.25 D) preoperatively to 0.08 ± 0.26 D (range 0.75 to -0.75), where 92 eyes (75.4%) were within ± 0.25 D and more than 80% of eyes were within ± 0.50 D of the target (r2=0.98). The mean Snellen decimal UDVA and CDVA were 0.91 ± 0.17 and 0.97 ± 0.09, respectively. Eighty eyes (66%) achieved UDVA of 20/20 or better and 115 eyes (95%) had UDVA of 20/40 or better; the efficacy index was 0.96 ± 0.14. One-hundred and three eyes (85.1%) achieved CDVA of 20/20 or better and all eyes evaluated had CDVA of 20/40 or better. No eyes lost any lines of CDVA and 22 eyes (18%) gained 1 or more lines of CDVA; the safety index was 1.04 ± 0.10. No intraoperative complications.

Conclusions:

The outcomes of predictability, safety and effectiveness of V4b ICL model are good and comparable with previous ICL models throughout 12 moths follow-up. These results suggest the V4b ICL model is a right option to correct moderate to high levels of myopia. FINANCIAL INTEREST: NONE
