Abstract Details


To evaluate the refractive and visual results, security and predictability of posterior segment lens ICL V4C (Staar®) implantation to treat moderate to high myopia.


Department of Ophthalmology, Hospital de Braga, Portugal


Inclusion criteria: Patients undergoing posterior segment lens V4C for treating myopia with 12 and 24 months of follow-up and normal pre-operative ophthalmologic examination. Exclusion criteria included those with insufficient follow-up time, ICL V4B lens implantation for treating hyperopia, secondary procedures to previous anterior segment surgery (namely intracorneal segments or LASIK) and patients with keratoconus. The following parameters were assessed; visual acuity (uncorrected and with correction), sphere, cylinder, spherical equivalent, central vault, central endothelial counts and induced astigmatism vectorial count.


33 eyes of 19 patients were included following ICL V4C lens implantation for correcting myopia and astigmatism. Mean age was 30,39 ±7,37 years old. Pre-operative sphere and cylinder power was -5,90±4,24 D and -1,29±1,45 D, respectively; post-operative sphere and cylinder power was 0,11 ±0,32 D and -0,46 ±0,33 D, respectively. Refractive predictability was high: 88% ±0,50 D and 100% ±1,00 D; Efficiency ratio was 1,00 and security ratio was 1,14; All patients kept or registered higher best corrected visual acuity lines.There was a mean endothelial loss of 2.06% at 12 months and 3.30% loss at 24 months of follow-up. Mean central vault at 24 months was 539,24 ±327,98 μm. No cases of cataract or intraocular hypertension were registered


Posterior segment lens ICL V4C implantation is an effective and safe procedure for treating moderate to high ametropies.
