Abstract Details

Purpose:

The aim of our work is to evaluate the incidence and results of laser enhancement in patients after cataract surgery and RLE ( refractive lens exchange) with FineVision Micro F trifocal lens implantation (PhysIOL, Liège, Belgium).

Setting:

Gemini Eye Clinic, Prague, Czech Republic

Methods:

Retrospective study of 1129 eyes of 596 patients who underwent an uncomplicated cataract surgery (679 eyes) and a RLE surgery (450 eyes) with trifocal FineVision Micro F lens implantation in the period from 09/2014 to 6/2018. We determined the rate of laser enhancement of residual refractive error in both groups. Uncorrected distance visual acuity (UCDVA), best corrected distance visual acuity (BCDVA), uncorrected near visual acuity (UCNVA) before and after laser correction, preoperative and postoperative spherical equivalent (SE) and type of laser surgery were evaluated.

Results:

Laser enhancement was performed in 61 eyes (5.4%), out of which 30 eyes (4.4%) in cataract group and 31 eyes (6.9%) in RLE group. Laser correction by FemtoLASIK was performed in 11 eyes, the PRK method in 50 eyes.The mean UCDVA before laser enhancement was 0.26 ± 0.19 logMAR in FemtoLASIK group and 0.24 ± 0.14 in PRK group. After a laser enhancement it reached 0.04 ± 0.05 logMAR in FemtoLASIK group and 0.13 ± 0.19 in PRK group. UCNVA, evaluated based on Jaeger optotypes, improved from values of 2-3 before laser enhancement to 1-2 after laser enhancement.

Conclusions:

Implantation of FineVision Micro F (PhysIOL, Liège, Belgium) trifocal lens is an effective solution for gaining independence from spectacle correction. With a properly guided and adequate preoperative strategy in the indication and selection of the dioptric power of the lens, the incidence of residual refractive error requiring laser enhancement is low. Any laser correction of residual refractive error is, according to our experience, a safe and effective solution for improving the quality of vision and patient satisfaction.
