METHODS:This retrospective case series included 222 consecutive eyes implanted with the trifocal FineVision Micro-F IOL (PhysIOL) after laser corneal refractive surgery. The series was divided into two groups according to safety outcomes after lensectomy: eyes with loss of one or more lines of corrected distance visual acuity (CDVA) [n = 59, 26.5%]) (failed eyes group) and eyes with no loss or gain in CDVA lines (n = 163, 73.4%]) (successful eyes group). Distribution of tomographic corneal aberrations (spherical aberration [Z40], comatic and root mean square of higher order aberrations [RMS-HOA]), laser corneal refractive surgery error, kappa angle, and CDVA after laser corneal refractive surgery were compared among both groups. RESULTS:Mean CDVA after lensectomy was 0.15 ± 0.07 logMAR (range: 0.05 to 0.30 logMAR) versus 0.03 ± 0.04 logMAR (range: 0.00 to 0.15 logMAR) in the failed and successful eyes groups, respectively (P < .001). Comparison of both groups showed that failed eyes had a statistically significantly higher grade of hyperopic laser corneal refractive surgery than successful eyes measured as mean sphere (+0.71 ± 3.10 diopters [D] [range: −7.75 to +6.00 D] vs −0.46 ± 3.70 D [range: −10.75 to +6.00 D], P < .01), spherical equivalent (+0.27 ± 3.10 D [range: −8.00 to +5.50 D] vs −0.97 ± 3.60 D [range: −12.50 to +4.90 D], P < .05), and percentage of hyperopic laser corneal refractive surgery (64% vs 43.5%, P < .05). Corneal aberration analysis showed that mean Z40 values were significantly more negative in the failed eyes group than in the successful eyes group (+0.07 ± 0.40 mm [range: −0.82 to +0.65 mm] vs +0.18 ± 0.37 mm [range: −0.79 to +0.87 mm], P < .05). Laser corneal refractive surgery cylinder was distributed homogeneously between both groups, as well as coma and RMS-HOA, kappa angle, and CDVA after laser corneal refractive surgery that were not statistically significant. CONCLUSIONS:Surgeons should consider tomographic corneal spherical aberration after implantation of a trifocal IOL in eyes after keratorefractive surgery, particularly in eyes previously treated with hyperopic laser corneal refractive surgery, to prevent loss of lines of visual acuity after lensectomy.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/journal articleopen access10.3928/1081597X-20220207-01
