Purpose
To determine the effect of LASIK complement surgery on visual outcomes in patients with trifocal IOL implantation with a history of refractive surgery
Setting
Research Department at Ofttalmosalud, Instituto de Ojos, Lima, Peru.
Methods
This is an observational retrospective cohort study that included 25 eyes of 18 patients who underwent LASIK complement after trifocal IOL implantation with a history of refractive surgery, at the Instituto Oftalmosalud in Lima, Peru, between January 2021 and September 2021. The variables of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), subjective refraction, spherical equivalent (SE) and high order aberrations (HOA) were evaluated, these measurements were performed preoperatively and postoperatively within 1 month and 12 months; intraoperative complications were also recorded. Statistical analysis was performed with R softwear
Results
The mean age was 58.7 ± 7.7 years. Mean UDVA before LASIK complement was 0.29 ± 0.25 LogMAR and after LASIK add-on was 0.13 ± 0.20 LogMAR (p=0.032); no significant change in CDVA was observed. Refractive changes were mean sphere -0.43 ± 0.57 versus -0.23 ± 0.59 (p=0.170), mean cylinder -0.83 ± 0.38 versus -0.28 ± 0.25 (p<0.001) and mean SE -0.85 ± 0.63 versus -0.38 ± 0.60 (p=0.021). After treatment, no changes in higher order aberrations, nor intraoperative complications were observed.
Conclusions
The LASIK complement after trifocal IOL implantation with a history of refractive surgery was effective in correcting UDVA, LASIK complement is safe, efficient, and predictable.
