Abstract

CLINICAL RELEVANCE: Having an understanding of the refractive outcomes of different forms of cataract surgery will assist optometrists in explaining the implication of such procedures to patients being referred for such procedures. BACKGROUND: The purpose of this study was to compare the refractive outcomes after toric intraocular lens implantation between femtosecond laser-assisted cataract surgery and traditional phacoemulsification. METHODS: This retrospective non-randomised case series included 114 eyes of 92 consecutive patients (59 male and 55 female) aged 71.65 +/- 10.46-years (range 57 to 92-years), who underwent either femtosecond laser-assisted cataract surgery (using two laser platforms) (group 1) or traditional phacoemulsification (group 2) between August 2013 and September 2015. Pre-operative keratometric values, the attempted refraction from the biometry platform and the toric intraocular lens web-based calculator, and the one month post-operative manifest refraction were assessed to evaluate the refractive outcomes of the two groups. RESULTS: Mean pre-operative topographic corneal astigmatism was -1.94 +/- 0.73 D (range 0.91 to 4.61 D) and -1.98 +/- 0.60 D (range 1.07 to 3.43 D) for groups 1 and 2, respectively (p > 0.05). Mean axial length was 24.22 +/- 0.73-mm (range 21.78 to 29.30-mm) and 24.60 +/- 1.09-mm (range 21.82 to 25.95-mm) for groups 1 and 2, respectively (p > 0.05). Multivariate vector analysis of the remaining refractive error between the two groups (desired refraction minus achieved refraction) revealed no statistically significant difference (p > 0.05). Analysis within each group demonstrated a higher accuracy of refractive outcomes for the femtosecond laser-assisted cataract surgery eyes (p < 0.05) when compared to the traditional phacoemulsification (p > 0.05). CONCLUSION: Femtosecond laser-assisted cataract surgery and traditional phacoemulsification demonstrate similar refractive outcomes after toric intraocular lens implantation, while femtosecond laser-assisted cataract surgery seems to provide a slightly higher accuracy.
