“…Explantation was performed in 6 treated eyes (7.4%) because of halos, glare, and reduced UDVA. Beer et al [21] reported the 1-year clinical outcomes of 31 patients. The mean UNVA improved to 0.17 logMAR, and 87.1% of the patients showed 0.3 or better UNVA.…”

“…50.0% of patients answered that they never used spectacles for near work, whereas Limnopoulou et al [19] reported that 81.25% of their patients perceived their UNVA as excellent, and 93.75% were independent of their spectacles. Also, Beer et al [21] reported that 91% of their patients subjectively rated their UNVA as excellent or good, and 65% never used spectacles for near vision. Direct comparisons to previous studies might be irrelevant because of different scoring systems, but our study seems to report relatively low patient satisfaction.…”

“…The Flexivue Microlens is a refractive optic corneal inlay that alters the corneal index of refraction to improve near vision performance by means of a bifocal optic that separates distance and near focal points [18]. Previous studies showed encouraging outcomes and safety, including increased near visual acuity, high patient satisfaction, and stable corneal structure [19–21]. But insufficient clinical evaluation of the Flexivue Microlens inlay has been done to confirm its efficacy and safety.…”

Background To evaluate the 6-month clinical outcomes of Flexivue Microlens refractive corneal inlay in emmetropic patients in Asia for the surgical compensation of presbyopia. Methods In this retrospective study, corneal inlay implantation was done using a femtosecond laser. The follow-up period was 6 months. Near/intermediate/distant visual acuities, refraction, keratometry, defocus curve, wavefront aberrations, contrast sensitivity, Scheimpflug corneal scanning, endothelial cell density, dry eye test, confocal microscopy scanning, and patient questionnaires were evaluated. Results The inlay implantation was performed in 21 eyes from June 2015 to April 2017. 6 months after surgery, the uncorrected near visual acuity of the operated eyes increased significantly from 0.55 ± 0.22 logMAR preoperatively to 0.25 ± 0.15 logMAR ( p < 0.05) but mean bilateral uncorrected distant visual acuity did not change significantly ( p = 0.90). Total higher-order aberration and spherical aberration increased, and the contrast sensitivity of the operated eyes decreased. Endothelial cell density and central corneal thickness did not change from preoperative values. Patient satisfaction for near vision was increased 6 months after implantation, and 50.0% of patients were independent of near spectacles. Explantation was done in 2 cases. Conclusion The Flexivue Microlens refractive corneal inlay was effective for improving near visual acuity at 6 months follow-up But proportion of spectacle independency and patient satisfaction were lower in this Korean population than in previous reports. Further study with a longer follow-up period is needed.
