Purpose. To evaluate the incidence of laser enhancement following cataract surgery and refractive lens exchange (RLE) with FineVision Micro F trifocal lens implantation (PhysIOL, Liège, Belgium).

Methods: Retrospective study of patients who had undergone cataract or RLE surgery and had received a FineVision Micro F intraocular lens. Laser enhancement of residual refractive error was determined. Visual acuity (VA) assessments were performed before and after surgery: uncorrected distance VA (UCDVA), best-corrected distance VA (BCDVA), uncorrected near VA (UCNVA), plus preoperative and postoperative spherical equivalent (SE) assessments.

Results: Of the 1129 eyes from 596 patients, 61 (5.4%) required laser enhancement to correct residual refractive error (by group: 30/679 eyes [4.4%] cataract; 31/450 eyes [6.9%] RLE). Eleven eyes received FemtoLASIK; 50 eyes received PRK. Mean UCDVA before laser enhancement was 0.26±0.19 logMAR and 0.24±0.14 in the FemtoLASIK and PRK groups, respectively. After laser enhancement, these were 0.04±0.05 logMAR and 0.13±0.19, respectively; BCDVA values were 0.00±0.00 logMAR in the FemtoLASIK group and 0.06±0.11 in the PRK group. Laser enhancement improved UCNVA (Jaeger) from 2-3 to 1-2 in both groups. Enhancement reduced preoperative SE of -0.39±0.99 D and -0.53±0.58 D (FemtoLASIK and PRK groups, respectively) to 0.24±0.36 D and 0.04±0.47 D.

Conclusions: The FineVision Micro F trifocal lens is an effective solution for gaining increased spectacle independence. The incidence of residual refractive error requiring laser enhancement is low, and laser procedures are a safe and effective solution for improving the quality of vision and patient satisfaction. Synopsis. Laser enhancement rates and outcomes were determined following cataract / refractive lens exchange surgery that used a trifocal IOL. Enhancement was safe and effective and rates were low (5.4%).
