Abstract Details

Purpose:

Phakic intraocular lens (pIOL) implantation for the treatment of myopia under -6,00 D is an alternative surgical procedure to corneal laser ablative techniques. Visual and refractive results for pIOL for moderate to high myopia have been extensively described. The purpose of this paper is to evaluate and compare the efficacy, safety and predictability of posterior chamber pIOL ICL model V4C for the correction of low and moderate to high myopia.

Setting:

Ophthalmology Department, Hospital de Braga, Portugal

Methods:

Retrospective, comparative study of patients submitted to posterior chamber pIOL ICL V4C for the correction of myopia. Inclusion criteria: age > 20, stable refraction for 12 months, ACD > 2,80 mm, normal endothelial profile and normal topography. Minimum follow-up was 12 months. Analysed parameters: uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), subjective refraction (sphere, cylinder and spherical equivalent SE), safety and efficacy indexes, predictability evaluation, mean endothelial cell loss. Two groups of patients were created for analyses: group 1 (SE equal or inferior to -6,00 D) and group 2 (SE superior to -6,00 D).

Results:

A total of 134 eyes were included, 57 in group 1 and 77 in group 2. The mean preoperative SE was -4,05 D ᄆ 2,39 in group 1 and -9,55 D ᄆ 3,55 (p<0,05) in group 2, the refractive astigmatism was similar in both groups (p>0,05). The preoperative BCVA was 0,90 ᄆ 0,12 in group 1 and 0,80 ᄆ 0,19 in group 2 (p<0,05). At 12 month, we observed a significant improvement of all parameters in each group (p>0,05). Refractive predictability was high for both groups (p>0,05) and the percentage of eyes between ᄆ 0,50 D was 92% and 96%.

Conclusions:

Posterior chamber ICL pIOL implantation is a safe, effective and predictable surgical procedure for the correction of low and moderate-high myopia; it is a viable procedure when corneal laser ablative procedures for low ametropia are not indicated or applicable.
