Purpose

To evaluate clinical retinal optical image quality following implantation of a phakic Implantable Collamer Lens ICL (EVO-V5, STAAR Surgical, Nidau, Switzerland)

Setting

Hospital Arruzafa. Córdoba

Methods

This prospective, descriptive study included 20 eyes implanted with myopic (alone ore combined with astigmatism) or hyperopic ICL. Total root mean square, ocular lower (LOA) and higher (HOA) order aberrations and spherical aberration were analyzed using Pentacam Wave aberrometer at two different pupil sizes (3 and 4mm).

Results

Preoperatively, LOA, HOA and spherical aberration at 3 and 4mm diameter were 2.16±0.82 and 3.61±1.26, 0.06±0.03 and 0.11±0.05, 0.02±0.02 and 0.02±0.02, respectively.

One month after surgery, LOAs had decreased in both pupil sizes to 0.26±0.09 (p=0.007) and 0.44±0.09 (p= 0.01), respectively. For HOA, a slight increase was obtained to 0.07±0.02 (p=0.49) and 0.13±0.03 (p=0.05). Finally, spherical aberration was similar to before surgery with 0.02±0.01 (p= 0.12) and 0.03±0.03 (p=0.54).

Conclusions

The  outcomes found in this study lead us to conclude that the ICL V5 model provides good optical quality, by means of different metrics, when implanted.
